To find the total amount, you will use the formula for finding compounded interest.  This means you will be paid interest on top of the interest you have earned each year.

A = P(1 + r)^nt
P stands for the principal.
r is the interest rate when compounded annually
nt is the number of years

A = 17.50(1 + 0.04)^25
A = $46.65

This person would have $46.65 after 25 years.

The table shows three values of x and their corresponding values of f (x) for a linear function f, such that f (r) = 0 and f (0)
Rus_ich [418]

Using a linear function, it is found that the product rs is rs = 81.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, when x changes by 68(from -64 to 68), y changes by -16(from 12 to -4), hence the slope is given by:

m = -16/64 = -0.25.

Hence:

y = -0.25x + b.

When x = 34, y = -4, hence this is used to find b.

-4 = -0.25(34) + b

b = 4.5.

Hence the function is:

y = -0.25x + 4.5.

f(r) = 0, hence:

-0.25x + 4.5 = 0

x = 4.5/0.25

x = 18

r = 18.

f (0) = s, hence s = 4.5.

Then the value of the product is:

rs = 18 x 4.5 = 81.

KengaRu [80]

Answer: C) 40 degrees

Step-by-step explanation:

if the total angle is 70 degrees and part of it is 30 degrees

then the other part is x degrees

30 + x = 70

30 - 30 + x = 70 - 30

x= 40

Hope this helped!
