Answers

Answer 1

The first three terms of the AP are -4.28, -7.28, -10.28

What is arithmetic sequence?

An arithmetic sequence in algebra is a sequence of numbers where the difference between every two consecutive terms is the same.

Given that, the sum of the first 9 terms of an AP is 56 and the sum of the next 10 terms is 430. we need to find the first three terms of the AP.​

The sum of the first n terms in an arithmetic sequence is (n/2)⋅(a₁+aₙ). It is called the arithmetic series formula.

Therefore,

56 = 9/2(2a₁+(9-1)d)

12.44 = 2a₁+7d

2a₁ = 12.44-7d....(i)

430 = 19/2(2a₁+18d)

45.26 = 2a₁+18d

2a₁ = 45.26-18d....(ii)

Equating the RHS of the equations,

12.44-7d = 45.26-18d

11d = 32.82

d = 3

Put d = 3, in equation (i)

2a₁ = 12.44-7(3)

2a₁ = -8.56

a₁ = -4.28

Therefore, the next three terms = -4.28, -7.28, -10.28

Hence, the first three terms of the AP are -4.28, -7.28, -10.28

−8(1+x)+7x pleaseeeeeeeeeeeee

Answers

-8-8x+7x

*Collect like terms

-8-x


Solution

-8-x

Answer:

To simplify the expression −8(1+x)+7x, we can use the distributive property of multiplication over addition, which states that a(b+c) = ab + ac. Applying this property, we get:


−8(1+x) + 7x = −81 − 8x + 7x (distributing the -8)

= -8x - 8 + 7x (simplifying the multiplication)

= -x - 8 (combining like terms)


Therefore, the simplified form of the expression −8(1+x)+7x is −x − 8.

Question 10 Leon has four barrels, each with a mass of 30kg to the nearest 10 kg. (a) Find the minimum possible mass of the four barrels. (b) Find the maximum possible mass of the four barrels​

Answers

Answer:

Step-by-step explanation:

(a) To find the minimum possible mass of the four barrels, we want to arrange them in a way that minimizes the total mass. One way to do this is to put the two lightest barrels together and the two heaviest barrels together. This way, the total mass is minimized because the lighter barrels balance out the heavier ones.

So, the minimum possible mass of the four barrels is:

2(30 kg) + 2(30 kg) = 120 kg

(b) To find the maximum possible mass of the four barrels, we want to arrange them in a way that maximizes the total mass. One way to do this is to put the heaviest barrel with the lightest barrel and the other two barrels together. This way, the total mass is maximized because the heaviest and lightest barrels are paired together, making the total mass greater than if they were all paired together.

So, the maximum possible mass of the four barrels is:

30 kg + 90 kg + 30 kg + 30 kg = 180 kg

Write a PYTHON program that:
1) Asks the user to input a sequence of comma separated numbers, e.g., 4,6,7,454,78 (no space in between)
2) Transforms the input string into a list using the function split(). For example, userstr.split(',') will split the string userstr at each ',' and return a list of separated items.
3) Checks whether the user input is all-digit (use .isdigit() function). If yes, go to next step; if not, let the user try until they get it right.
4) Converts all items in the list into integer
5) Adds all numbers together and return the sum.

Answers

Answer:

while True:

   user_input = input("Please enter a sequence of comma-separated numbers: ")

   if user_input.replace(",", "").isdigit():

       break

   print("Invalid input! Please try again.")

num_list = user_input.split(",")

num_list = [int(num) for num in num_list]

total_sum = sum(num_list)

print("The sum of the numbers is:", total_sum)

Step-by-step explanation:

This program uses a while loop to repeatedly ask the user for input until they provide a valid sequence of comma-separated numbers (all-digit input). The .isdigit() function is used to check if the input is all-digit. If the input is valid, the program splits the input string at each ',' using the .split() function, converts each item in the resulting list into an integer using list comprehension, then adds all numbers together using the sum() function. Finally, the program outputs the total sum.

Let f(x) = x2 + x - 6 and g(x) = 7x + 3. Find g(1) and f(g(1)).
PLEASE HELP ME ASAP !!!

Answers

Answer:

g(1) = 10f(g(1)) = 104

Step-by-step explanation:

You want the values of g(1) and f(g(1)), given that f(x) = x² +x -6 and g(x) = 7x +3.

Function evaluation

To find the value of a function for a particular argument (value of x), put that value where x is and do the arithmetic.

  g(1) = 7·1 +3 = 7 +3 . . . . . use 1 in place of x in 7x+3

  g(1) = 10

For f(g(1)), we first need to find g(1). We already did that, above.

  f(g(1)) = f(10) = 10² +10 -6 - 100 +10 -6 = 110 -6

  f(g(1)) = 104

B) x= 4, 14

C) x= -3, 4

D) x= -3, -7

Answers

Answer:

C

Step-by-step explanation:

x + y + 10 = 0 ( subtract x + 10 from both sides )

y = - x - 10 → (1)

x² + y - 2 = 0 → (2)

substitute y = - x - 10 into (2)

x² - x - 10 - 2 = 0

x² - x - 12 = 0 ← in standard form

(x - 4)(x + 3) = 0 ← in factored form

equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 4 = 0 ⇒ x = 4

A quadratic equation is an equation which can be expressed as; f(x) = a·x² + b·x + c, where a, b, and c are real numbers and a ≠ 0.

1. √(30 - x) = x

x = √(30 - x)

x² = 30 - x

x² + x - 30 = 0

Factoring the above quadratic equation, we get;

(x + 6)·(x - 5) = 0

x = -6 and x = 5

2. x = √(42 - x)

x² = 42 - x

x² + x - 42 = 0

(x + 7)·(x - 6) = 0

x = -7 and x = 6

3. √(12 - r) = r

Squaring both sides of the equation, we get;

r² + 2·r + 1 = 0

(r + 1)² = 0

r = -1

6. √(4·n + 8) = n + 3

4·n + 8 = (n + 3)² = n² + 6·n + 9

4·n + 8 = n² + 6·n + 9

n² + 6·n + 9 - (4·n + 8) = 0

n² + 6·n + 9 - 4·n - 8 = 0

(n + 1)² = 0

n = -1

7. -n + √(6·n + 19) = 2

-n + √(6·n + 19) = 2

√(6·n + 19) = n + 2

(6·n + 19) = (n + 2)² = n² + 4·n + 4

6·n + 19 = n² + 4·n + 4

n² + 4·n + 4 = 6·n + 19

n² + 4·n + 4 - (6·n + 19) = 0

√(-3·m + 10) = m - 4

-3·m + 10 = (m - 4)² = m² - 8·m + 16

-3·m + 10 = m² - 8·m + 16

Loren already knows that he will have $500,000 when he retires. If he sets up a payout annuity for 30 years in an account paying 10% interest, how much could the annuity provide each month?

Answers

Loren could receive a monthly payout of approximately $4,646.81 from the annuity to last for 30 years at a 10% annual interest rate.

What is annuity?

A contract between you and an insurance company known as an annuity entails you making a lump sum payment or a series of payments in exchange for regular payments starting either right away or in the future.

To calculate the monthly payout that Loren can receive from an annuity for 30 years, use the formula for the present value of an annuity -

PV = PMT x [(1 - (1 + r)^(-n)) / r]

Where PV is the present value of the annuity (the amount of money Loren has at retirement), PMT is the monthly payout, r is the monthly interest rate (10%/12 = 0.00833), and n is the number of monthly payments (30 years x 12 months/year = 360 months).

Substituting the given values into the formula -

$500,000 = PMT x [(1 - (1 + 0.00833)^(-360)) / 0.00833]

Solving for PMT -

PMT = $500,000 / [(1 - (1 + 0.00833)^(-360)) / 0.00833]

PMT = $4,646.81

Therefore, The value is obtained as $4,646.81.

Since the probability of rain on any given day is 0.5, and the weather on each day is independent of the others, we can calculate the probability of it raining all three days by multiplying the probabilities of rain on each individual day:

P(rain on day 1) x P(rain on day 2) x P(rain on day 3) = 0.5 x 0.5 x 0.5 = 0.125

What is a linear equation?

A linear equation is an equation of the form; y = m·x + c, where the slope of the graph of the equation is m and the y-intercept of the graph is c.

The analysis of the equations in the table are as follows;

Equation for Pinehill is; P = 800 - 20t

The slope of the above equation is; -20 and the y-intercept is 800. The negative sign for the slope indicates that the population is decreasing;

Therefore, the initial population of 800 in Pinehill is decreasing at a rate of 20 per unit time, t

Population for Rye; P = 500 + 15t

The population of Rye is increasing at a rate of 15 per unit time

Population for Smithfield; P = 10t + 950

The population of Smithfield is increasing at a rate of 10 per unit time

Population for Troy; P = -50·t + 600

The -50 indicates that population is decreasing at a rate of 50 per unit time

The solution of the system of equations is

x = 1/2 and y = -2

What are system of equations?

A system of equations are a pair of equations.

How to solve the system of equations?

Given the system of equations

4/x - 2/y = 12 (1) and

5/x + 1/y = 8 (2)

We proceed to solve as follows.

Since we have

4/x - 2/y = 12 (1) and

5/x + 1/y = 8 (2)

Multiplying equation (1) by 1 and equation (2) by 2, we have that

4/x - 2/y = 12 (1) × 1 and

5/x + 1/y = 8 (2) × 2

4/x - 2/y = 12 (4)  and

10/x + 2/y = 16 (5)

Now, adding equations (4) and (5), we have that

4/x - 2/y = 12 (4)  

+

10/x + 2/y = 16 (5)

14/x = 28

14 = 28x

x = 14/28

x = 1/2

Substituting x = 1/2 into equation (1), we have that

4/x - 2/y = 12 (1)

4/(1/2) - 2/y = 12 (1)

4 × 2 - 2y = 12

8 - 2y = 12

-2y = 12 - 8

-2y = 4

y = 4/-2

y = -2

So,

x = 1/2 and y = -2

Olivia planted bean seeds. After they started to grow, she measured their heights and recorded the heights in the line plot below. image a97cc9c5036040c58918973d56401d70 How many plants were less than 3 cm tall? A. 1 B. 18 C. 14 D. 3 answers

The height of the balloon is 1.3 miles above the ground.

What is height?

Height is the measure of vertical distance, either how "tall" something or someone is, or how "high" the point is. For example, a person's height is typically measured using a stadiometer and is recorded in centimeters or feet and inches. The height of a mountain is usually measured in meters or feet. In aviation, height is measured from the surface of the earth, either above ground level (AGL) or above mean sea level (AMSL).

The answer to this question can be found by using the trigonometric formula of Tangent. To calculate the height of the balloon, we must find the length of the hypotenuse in the triangle formed by the two towns and the balloonist.

Using the formula for tangent, we can calculate the length of the hypotenuse. The formula is:

tan (angle) = opposite side/adjacent side

In this case, the opposite sides are the two towns, and the adjacent side is the height of the balloon.

For the first town, the formula is:

tan 36° = 1.6/x

Solving for x, we can calculate the length of the hypotenuse for the first town to be 2.8 miles.

For the second town, the formula is:

tan 32° = 1.6/x

Solving for x, we can calculate the length of the hypotenuse for the second town to be 2.9 miles.

Since the hypotenuse is the total distance between the two towns and the balloonist, the height of the balloon can be calculated by subtracting the total length of the two towns (1.6 miles) from the hypotenuse of the second town (2.9 miles).

The height of the balloon is 1.3 miles above the ground.

Answer:

What is height?

Height:

When a rectangle is drawn with horizontal and vertical sides, the word height makes it clear which dimension is meant; height labels how high (how tall) the rectangle is. That makes it easy to indicate the other dimension—how wide the rectangle is from side to side—by using the word width. And if the side-to-side measurement is greater than the height, calling it the length of the rectangle is also acceptable, as it creates no confusion.

You have $500,000 saved for retirement. Your account earns 6% interest. How much will you be able to pull out each month, if you want to be able to take withdrawals for 20 years?

Answers

The answer comes to $43,592.00. 28 can be wiped from the account after 20 years, leaving nothing behind.

What is a fascinating illustration?

Think about taking out a $1,000 loan with a seven-year, 10% interest rate. The first year's interest would cost you $100. You would pay $1,100 in interest the next year, which is the sum of the initial amount plus interest. Because of this, your salary for the upcoming year will be $110 (1,100 times 0.10).

Calculate the Yearly Amount (A) given the Prepaid Value (P), at interest rate I over n periods using the equation (A/P, I n).

The equation is:

[tex]A=P \frac{i(1+i)^n}{(1+i)^n-1}[/tex]

Where:

P is the Present value = $500,000

A is the monthly Amount

i is the interest rate = 0.06

20 years are the number of periods (n).

Substituting values:

[tex]A=\$ 500,000 \frac{0.06(1.06)^{20}}{(1.06)^{20}-1}=\$ 43,592.28[/tex]

This is linear equations please help me.

Answers

Answer:

              The x-intercept of Line A is (-3, 0), and the x-intercept of Line B is (-1, 0). Therefore, the x-intercept of Line A is less than the x-intercept of Line B.

Step-by-step explanation:

              The x-intercept of a graph or function is where the line hits the x-axis on a coordinate plane. In other words, the y-value of the x-intercept is 0. Since we are looking for the x-intercept of Line A, we can use the given equation to solve for it by inserting the value y = 0 (as mentioned above, the x-intercept of a function will have the y-value as 0). By solving the equation, you'll get that [tex]-2=\frac{1}{3} (x-3)[/tex] ⇒ [tex]-6=x-3[/tex] ⇒ [tex]x = -3[/tex]. Therefore, the x-intercept of Line A is (-3, 0).

              The x-intercept on a graph is easier to find, as it is where the line touches the x-axis. So the x-intercept of Line B would be (-1, 0). Now that we have both x-intercepts, we can compare them and come up with the final answer that is required. As -3 is less than -1, we can conclude that the x-intercept of Line A is (-3, 0), and the x-intercept of Line B is (-1, 0). Therefore the x-intercept of Line A is less than the x-intercept of Line B.

The number of hamburgers sold in the winter is 57 million.

What is percentage ?

Percentage is a way of expressing a fraction or ratio as a portion of 100. It is denoted by the symbol "%".

For example, if there are 10 green balls in a bag of 20 balls, we can say that the percentage of green balls is:

(10/20) x 100% = 50%

This means that 50% of the balls in the bag are green.

Percentages are often used to represent proportions or amounts in many contexts, such as finance, statistics, and everyday life. They can be used to express changes, comparisons, and relationships between different quantities.

In addition, percentages are commonly used in calculations involving tax, interest rates, discounts, and other types of financial transactions. It is important to have a good understanding of percentages in order to manage personal finances, make informed business decisions, and interpret data accurately.

Let's suppose that the total number of hamburgers sold by the fast food chain in a year is represented by the height of the bars in the bar graph. We know that 25% of the hamburgers are sold in the fall, which means that the bar representing the fall sales must be 25% of the total height of the bars.

Since there are four seasons in a year, each season must represent 25% / 4 = 6.25% of the total height of the bars. Therefore, the height of each bar is 6.25% of the total number of hamburgers sold.

Let's denote the number of hamburgers sold in the winter by x. Then, the height of the winter bar is also x/100 of the total height of the bars.

We know that the winter bar is covered by a smudge, but we can still use the information we have to set up an equation. Since the heights of the bars must add up to the total height, we can write:

25% + 6.25% + 6.25% + 6.25% + x/100 = 100%

Simplifying the left-hand side, we get:

43% + x/100 = 100%

Subtracting 43% from both sides, we get:

x/100 = 57%

Multiplying both sides by 100, we get:

x = 57 million hamburgers.

Therefore, the number of hamburgers sold in the winter is 57 million.
