Lucy received a $1300 bonus. She decided to invest it in a 3-year certificate of deposit (CD) with an annual interest rate of 1.27% compounded monthly.
Answer the questions below. Do not round any intermediate computations, and round your final answers to the nearest cent. If necessary, refer to the list of financial formulas.
(a) Assuming no withdrawals are made, how much money is in Lucy's account after 3 years?
$____
(b) How much interest is earned on Lucy's investment after 3 Years?
$____
Answer:
(a) $1350.46
(b) $50.46
Step-by-step explanation:
You want to know the future value of a $1300 CD earning 1.27% compounded monthly for 3 years, along with the amount of interest earned.
Future valueThe compound interest formula tells you the future value is ...
FV = P(1 +r/12)^(12·t)
where r is the annual interest rate and t is the number of years.
ApplicationUsing the given values, we have ...
FV = $1300(1 +0.0127/12)^(12·3) ≈ $1350.46
(a) The value after 3 years is $1350.46.
The interest earned is the difference between the final value and the amount of the original investment:
Interest = $1350.46 - 1300.00 = $50.46
(b) The interest earned by the CD is $50.46.

Celine is training to run a marathon. During her training, she kept track of how much time
she spent running on the treadmill inside and on a trail outside each week. These box plots
show the results.
Where was there more variation in the amount of time Celine spent running?
Answer:
There was more variation in her time spent running outside.
Step-by-step explanation:
This is because the range for running outside is larger.
To find range you subtract the largest number in the data by the smallest.
RANGE FOR INSIDE: 150 - 25 = 125
RANGE FOR OUTSIDE: 200 - 50 = 150
Since the range is larger for the time outside spent running, there is more variation.
Given that ZQRP = (2x + 20) and ZPSQ = 30°, find the value of x.
The value of x is 65. Please note that this solution is based on the assumption that the angles QRP and PSQ are supplementary. If this assumption doesn't hold, feel free to let me know.
We need to find the value of x in the equation ZQRP = (2x + 20)° given that ZPSQ = 30°. Since the question doesn't provide enough information about the relationship between angles QRP and PSQ, I'll assume that they are supplementary angles (angles that add up to 180°). This assumption is based on the possibility that the angles form a straight line or a linear pair.
If angles QRP and PSQ are supplementary, their sum is 180°:
(2x + 20)° + 30° = 180°
Now, we can solve for x:
2x + 50 = 180
Subtract 50 from both sides:
2x = 130
Divide by 2:
x = 65

Carly will need to buy 27.05 gallons of gas for the trip, which will cost her $7.28.
To calculate the total cost of the road trip, we need to find out how many gallons of gas Carly will need and then multiply that by the cost per gallon.
First, we need to convert the distance from miles to gallons, using the truck's fuel efficiency of 21 miles per gallon
568 miles ÷ 21 miles per gallon = 27.05 gallons
So Carly will need approximately 27.05 gallons of gas for the trip.
Next, we need to convert the cost of gas from liters to gallons. There are 3.79 liters in 1 gallon, so the cost of gas is:
$1.02 per liter ÷ 3.79 liters per gallon = $0.269 per gallon
Finally, we can calculate the total cost of the road trip by multiplying the number of gallons of gas by the cost per gallon
27.05 gallons × $0.269 per gallon = $7.28
Therefore, the road trip will cost Carly approximately $7.28.

imagine that you are offered two jobs. there is a 50% chance that you will take the first job and a 40% chance that you will take the second job. assume that you cannot take both jobs. what is the probability that you will take either one job or the other job?
Answer:
The probability of taking either one job or the other job can be calculated by adding the probabilities of taking the first job and taking the second job, and then subtracting the probability of taking both jobs (since we cannot take both).
Let A be the event of taking the first job, and B be the event of taking the second job. Then, the probability of taking the first job is P(A) = 0.5, and the probability of taking the second job is P(B) = 0.4. The probability of taking both jobs is zero, since we cannot take both.
Therefore, the probability of taking either one job or the other job is:
P(A or B) = P(A) + P(B) - P(A and B)
= 0.5 + 0.4 - 0
= 0.9
So the probability of taking either one job or the other job is 0.9 or 90%

The average rate of change of each function on the interval 2 ≤ x ≤ 6 is given as follows:
f(x): -1.25.g(x): -0.715.How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.
For the function f(x), we have that:
When x = 2, y = 7.When x = 6, y = 2.Hence the rate is given as follows:
r = (2 - 7)/(6 - 2)
r = -5/4
r = -1.25.
For the function g(x), we have that:
When x = 2, y = 2(-5/7) - 6 = -7.43.When x = 6, y = 6(-5/7) - 6 = -10.29.Hence the rate is given as follows:

what is arithmetic progression ?The phrase "arithmetic progression" (AP) describes a series of numbers in which every term—aside from the first—is derived by multiplying the previous term by a set value. The common difference is a constant number. The following equation can be used to symbolise an arithmetic progression: a n = a 1 + (n-1)d where d is the clear differentiation, a n is the n - th term, a 1 represents the initial term, and n is the total number of terms. For instance, an arithmetic progression with 5 terms and a common difference of 3 starting at 1 would be: 1, 4, 7, 10, 13
given
The formula for the sum of an arithmetic series can be used to determine the total number of contestants:
[tex]S = (n/2) * [2a + (n-1)d][/tex]
Here are the facts:
a = 23 (the first phrase) (the first term)
d = 7 (the usual difference, since each day 7 more participants enter the contest) (the common difference, since each day 7 more people enter the contest)
n = 28 (the number of terms, since the contest lasts 28 days) (the number of terms, since the contest lasts 28 days)
With these values entered into the formula, we obtain:
S = (28/2) * [2(23) + (28-1)(7)]
S = 14 * [46 + 189]
S = 14 * 235
S = 3290
Thus, 3290 persons in total have entered the contest. We calculated the sum using the following arithmetic series formula: S = (n/2) * [2a + (n-1)d].

What is 2^6*2^5 is other exponent?
Answer:
below
Step-by-step explanation:
Yes, there is another exponent.
When you are multiplying exponents, you add the exponents.
So from the equation 2^6 x 2^5, you can keep the 2 the same, as this is the base:
2^11
and add the exponents (6+5)
To check:
2^6=64
2^5=32
64x32=2048
2^11=2048
So, 2^11 is equivalent to your equation. Hope this helps ;)

A circle with center Q and equilateral triangle NOP, where points N and O lie on the circle
What is a circle?
A circle is a two-dimensional shape with a perfectly round boundary that has no corners or edges. It is defined as the set of all points in a plane that are equidistant from a fixed point called the center. The distance from the center to any point on the boundary of the circle is called the radius.
The circumference of a circle is the distance around the boundary of the circle, and it is calculated as 2π times the radius. Circles are found in many natural and man-made objects, such as wheels, planets, and coins, and they have a wide range of applications in mathematics, science, and engineering.
To construct a circle with center Q and equilateral triangle NOP where points N and O lie on the circle, follow these steps:
Draw line segment PQ as the base of the equilateral triangle NOP.
Draw a perpendicular bisector of PQ, which intersects PQ at its midpoint, say M. This bisector will be the axis of symmetry of the equilateral triangle NOP.
With M as the center and MP (or MQ) as the radius, draw a circle that intersects PQ at two points, say X and Y.
Using Q as the center and QX (or QY) as the radius, draw two arcs that intersect the circle drawn in step 3 at two points, say N and O.
Draw the lines NQ and OQ to complete the equilateral triangle NOP.
Now, you have a circle with center Q and equilateral triangle NOP, where points N and O lie on the circle.

given u=5i+4j and v = 4i-3j, determine -9u-v
-9u - v = -49i - 33j
To find -9u - v, you need to multiply the vector u by -9 and subtract the vector v from the result.
Given u = 5i + 4j and v = 4i - 3j, first multiply u by -9:
-9u = -9(5i + 4j) = -45i - 36j
Now, subtract the vector v from -9u:
-9u - v = (-45i - 36j) - (4i - 3j) = (-45i - 4i) + (-36j + 3j) = -49i - 33j
