Find the savings plan balance after 3 years with an APR of 7​% and monthly payments of ​$150.
Citrus2011 [14]

Answer:

The balance is $5989.5

Step-by-step explanation:

The savings plan balance is given by the following formula:

A = P*\left[\frac{(1 + \frac{APR}{n})^{n*Y} - 1}{\frac{APR}{n}}\right]

In which A is the savings plan balance, P is the monthly payment, APR is the annual percentage rate(decimal), n is the number of payments per year and Y is the number of years.

In this problem, we have that

Find the savings plan balance after 3 years with an APR of 7​% and monthly payments of ​$150.

So we have to find A when P = 150, APR = 0.07, n = 12, Y = 3.

So

A = P*\left[\frac{(1 + \frac{APR}{n})^{n*Y} - 1}{\frac{APR}{n}}\right]

A = 150*\left[\frac{(1 + \frac{0.07}{12})^{12*3} - 1}{\frac{0.07}{12}}\right]

A = 5989.5

The balance is $5989.5

4) Which graph represents a function?​
maxonik [38]

Answer:

C

Step-by-step explanation:

The other graphs do not pass the vertical line test (if you draw a vertical line through the line graphed, it should pass through once), but graph c <em>does</em> pass the test.

What is the sum of the first 5 terms of this geometric series? Use . -4 + 12 + (-36) + ⋯
yKpoI14uk [10]

Answer:

The sum of the first 5 terms is -244

Step-by-step explanation:

To calculate the sum of the geometric series, we need the first term, the common ratio and the number of terms we would like to sum.

The first term here is -4

The common ratio is T2/T1 or T3/T2 = 12/-4 = -3

number of terms n = 5

The formula to use is;

Sn = a(1-r^n)/(1-r)

Plugging these values, we have;

Sn = -4(1-(-3)^5)/(1-(-3))

Sn = -4(1+243)/4 = -1(244) = -244

Help please! I need to know if it’s a function or not!! Thank you!
BartSMP [9]

Answer:

The table represents a function and the slope is -1/2

Step-by-step explanation:

Here, we want to know if the given table is a function

For a relation to be a function, no two y values have same x value

however, 2 x values can have same y value

Looking at the table, we can conclude that what we have is a function

To find the slope, we select any two points and apply the slope formula

m = (y2-y1)/(x2-x1)

(x1,y1) = (6,-2)

(x2,y2) = (-2,2)

m = (2 -(-2))/(-2-6) = 4/-8 = -1/2
