a)The value of acceleration will be 4.8 m/s²

b)The total distance travelled is 505 m.

a) As all the movement happens along a straight line, we need to define an axis only, which we call x-axis, being the positive direction the one followed by the car.

We can choose to place our origin at the location where the motorcycle was stopped at the side of the road (assuming that it is the same point  for the car when it passes him), so our initial position is 0.

We can also choose our time origin to be the same as the instant that the motorcycle starts from rest, so t₀ = 0.

With these assumptions, and assuming also that the acceleration is constant, we can write two equations, one for the car (at constant speed) and the another one for the motorcycle, as follows:

xc = vx*t

xm= 1/2*a*t²

When the motorcycle passes the car, both distances traveled from the origin will be equal each other, i.e., xc = xm :

⇒ vx*t = 1/2*a*t²

We have as givens vx=35 m/s and t = 14.5 sec when both equations are equal each other.

⇒ 35 m/s* 14.5 s = 1/2*a*(14.5)²(s)²

Solving for a:

a = (2* 35 m/s) / 14.5 s = 4.8 m/s²

b) Replacing the value of a in the equation for xm, we have:

xm = 1/2*4.8 m/s²* (14.5)²s² = 505 m.

The values of x are 3 or 0. 3 and 0 will satisfy the equation |2x-3| +7 =10.

What is an absolute function?

A function that wraps an algebraic expression in absolute value symbols is known as an absolute value function. Remember that a number's distance from 0 on the number line represents its absolute value. The parent function with an absolute value is defined as f(x)=| x |.

Given equation is

|2x-3| +7 =10

Subtract 7 from both sides:

|2x-3| +7 - 7 = 10 - 7

|2x-3| = 3

Applying absolute function:

Either, 2x-3 = 3         or, 2x-3 = -3

Add 3 on both sides:

2x = 6                         2x = 0

We can rewrite our system of equations as:

x + y + z = 25

5x + y + 9z = 89

-7x + 6y + 6z = -6

First, if we subtract the first equation and the second one, we will get:

(5x + y + 9z) - (x + y + z) = 89 - 25

4x + 8z = 64

And if we subtract 6 times the first equation from the third one, we will get:

-7x + 6y + 6z - 6*(x + y + z) = -6 - 6*25

-13x = -156

We can solve this for x:

x = -156/-13 = 12

Now we know the value of x, replacing it in:

4x + 8z = 64

Will give:

4*12 + 8z = 64

8z = 64 - 4*12 = 16

z = 16/8 = 2

And the value of y will be given by:

x + y + z = 25

12 + y + 2 = 25

Using the given restrictions we can see that there are 37 balls on the box.

Let's assume that the total number of balls is B.

We know that in the box there are more than 25 and fewer than 40 tennis balls, so we have the inequality.

25 < B < 40

If we count in 3's, then there is one left over, so we can write:

B = 3*n + 1   (where n is an integer number)

And if we count in 5's there are 2 leftovers:

B = 5*m + 2  (where m is an integer, from this we conclude that the number ends in a 2 or a 7)

Then we have 3 restrictions:

25 < B < 40

B = 3*n + 1

B = 5*m + 2

notice that if n = 12

B = 3*12 + 1 = 37

if m = 7

Answer: The answer is  (A)

Step-by-step explanation:

The real GDP per capita increased by 28% from 2012 to 2013.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

We need to Write the percent as a fraction in simplest form

16.24%

So, we can rewrite it as;

16.24 / 100

16 and 24/100 or 16 6/25

So the percent as a fraction is 16 6/25

We are given that;

The table with GDP deflator and population

Now,

i. The percentage change in nominal GDP from 2012 to 2013 can be calculated as follows:

[(Nominal GDP in 2013 - Nominal GDP in 2012) / Nominal GDP in 2012] x 100

= [(112 - 75) / 75] x 100

= 49.33%

Therefore, nominal GDP grew by 49.33% from 2012 to 2013.

ii. Real GDP is nominal GDP adjusted for inflation. To find real GDP, we need to use the GDP deflator:

Real GDP (in billions) = Nominal GDP (in billions) / (GDP Deflator / 100)

In 2012: Real GDP = 75 / (50 / 100) = £150 billion

In 2013: Real GDP = 112 / (54 / 100) = £207.41 billion

iii. The percentage change in real GDP from 2012 to 2013 can be calculated as follows:

[(Real GDP in 2013 - Real GDP in 2012) / Real GDP in 2012] x 100

= [(207.41 - 150) / 150] x 100

= 38.27%

Therefore, real GDP grew by 38.27% from 2012 to 2013.

iv. To determine if the growth in nominal and real GDP increased the standard of living, we need to look at the change in real GDP per capita. Real GDP per capita is calculated by dividing real GDP by the population:

Real GDP per capita in 2012 = 150 / 50 = £3 billion

Real GDP per capita in 2013 = 207.41 / 54 = £3.84 billion

The percentage change in real GDP per capita can be calculated as follows:

[(Real GDP per capita in 2013 - Real GDP per capita in 2012) / Real GDP per capita in 2012] x 100

= [(3.84 - 3) / 3] x 100

= 28%

If the generation time of bacteria is 30 minutes, it means that in every 30 minutes, the number of cells will double. Let No = 100 be the initial number of cells, and n be the number of generations at that point.

Using the given formula N1 = N x 2^n, we can find the number of cells at any given time t, in minutes.

For t = 30 minutes:

The number of generations in 30 minutes is 1 (since generation time is also 30 minutes)

N1 = 100 x 2^1 = 200 cells

For t = 60 minutes:

The number of generations in 60 minutes is 2 (since generation time is 30 minutes)

N1 = 100 x 2^2 = 400 cells

For t = 90 minutes:

The number of generations in 90 minutes is 3 (since generation time is 30 minutes)

N1 = 100 x 2^3 = 800 cells

For t = 120 minutes:

The number of generations in 120 minutes is 4 (since generation time is 30 minutes)

N1 = 100 x 2^4 = 1600 cells

Therefore, after 30 minutes, the number of cells will be 200, after 60 minutes it will be 400, after 90 minutes it will be 800, and after 120 minutes it will be 1600.

The exponential equation that passes through these two points is:

y = 26.678*(14/11)^x

A general exponential equation is:

y = A*(b)^x

If we know the two points (3, 55) and (4, 70), then we can write  two equations:

55 = A*(b)^3

70 = A*(b)^4

If we take the quotient between the second equation and the first one, then we get:

70/55 = (A*(b)^4)/(A*(b)^3)

70/55 = b

14/11 = b

Then we can write:

The solution to the system of equation 2x - 3y = 4 and -2x + 6y = -10 is (-1,-2).

Given the system of equation in the question;

2x - 3y = 4

-2x + 6y = -10

First, solve for y in equation one.

2x - 3y = 4

2x - 4 = 3y

3y = 2x - 4

Divide each term by 3

y = (2/3)x - 4/3

Now, solve the system of equation, plug y = (2/3) - 4/3 into equation two and solve for x.

-2x + 6y =-10

Plug in y = (2/3) - 4/3

-2x + 6( (2/3)x - 4/3 ) = -10

Simplify

-2x + 4x - 8  = -10

2x - 8 = - 10

2x = -10 + 8

2x = -2

x = -2/2

x = -1

Now, plug x = -1 into equation two and solve for y.

-2x + 6y = -10

Plug in x = -1

-2( -1 ) + 6y = -10

2 + 6y = -10

6y = -10 - 2

6y = -12

The Standard deviation of the given data is 989.615.

The term "standard deviation" refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

We have data as

$54,410, $51,991, $51,730, $51,300, $51,196, $51,190, $51,122, $51,115, $51,037 and $50,875.

Also we have

Count, N: 10

Sum, Σx: 515966

Mean, μ: 51596.6

Now, using the formula of Standard Deviation

= √1/ N[tex]\sum_{i=1}^n (x_i- \mu)[/tex]²

= (54410 - 51596.6)² + (51991 - 51596.6)² +(51730 - 51596.6)² + (51300 - 51596.6)²+ (51122- 51596.6)² + (51115- 51596.6)² + (51037- 51596.6)² + (50875 - 51596.6)² / 10

= √9793384.4 /10

= √979338.44

= 989.615

Step-by-step explanation:

Simplifying the expression (2+1)2, we can first perform the operation within the parentheses, which gives us:

(2+1)2 = 3 x 2

Then, we can multiply 3 by 2, which gives us:

3 x 2 = 6

Therefore, the simplified expression for (2+1)2 is 6

It is found that the distance between the two memorials is of 1,42 miles.

The distance between two points (x1 , y1) and (x2 , y2) is of:

Distance formula = [tex]\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }[/tex]

One memorial is at point (3,-1).

The other is at point (7, -5).

Thus, in the coordinate grid, the distance is of:

D = 5.66

In the coordinate, the distance is of 5.66 units. Each unit is worth 0.25 miles, thus:

This graph shows how far Han is from his house as he drives. (0, 10) is the Y Vertical intercept. Han is therefore originally located 10 miles from his house.Horizontal intercept of X (10,0) It indicates that it takes 10 minutes to reach.

The point where the graphs of a function and relation meets the y-axis of the coordinate system is known as a y-intercept, also referred to as a vertical intercept. Analytic geometry is used for this, with the widely accepted standard that the variable y is represented by the vertical axis and the variable x by the horizontal axis.

Anything straight to the horizon is said to as horizontal. Since the vertical is the polar opposite of the horizontal, everything that intersects it at a right angle of 90 degrees is known as vertical. Hence, the line that runs form left to center is seen as being horizontal.

Step-by-step explanation:

To calculate the GPA of the student, we first need to calculate the total number of grade points earned by the student. We can do this by multiplying the number of credits for each course by the corresponding grade point value and then adding up the results:

A in a 3-credit course: 4 x 3 = 12 grade points

B in each of three 4-credit courses: 3 x 4 = 12 grade points each, for a total of 3 x 12 = 36 grade points

C in a 2-credit course: 2 x 2 = 4 grade points

D in a 3-credit course: 1 x 3 = 3 grade points

Total grade points earned = 12 + 36 + 4 + 3 = 55

Next, we need to calculate the total number of credits earned by the student:

A in a 3-credit course = 3 credits

B in each of three 4-credit courses = 3 x 4 = 12 credits

C in a 2-credit course = 2 credits

D in a 3-credit course = 3 credits

Total credits earned = 3 + 12 + 2 + 3 = 20

To find the GPA, we divide the total grade points earned by the total credits earned:

GPA = Total grade points earned / Total credits earned

GPA = 55 / 20

GPA = 2.75

Therefore, the GPA of the student is 2.75.

To calculate the GPA, convert each grade into points, multiply each point value by the number of credits for that course, and add the total. Then divide the total by the total credits. Using this calculation, the student's GPA is 2.75.

The grade point average (GPA) is calculated on the basis of the grades earned in each course and the course's credit value. First, each grade is converted into points. Then, each point value is multiplied by the number of credits for that course. Finally, the total points are added together, and the sum is divided by total credits to yield GPA.

The total credits are 3 (for A) + 12 (for Bs) + 2 (for C) + 3 (for D) = 20. The total points are 12 (for A) + 36 (for Bs) + 4 (for C) + 3 (for D) = 55. Hence, the GPA is 55 total points ÷ 20 total credits = 2.75.
