How do I workout/find the unknown angles please
Cerrena [4.2K]

Answer: x = 135 degrees and y = 225 degrees.

Step-by-step explanation: To solve this problem we first use the equation (n-2)*180 [n being the number of sides] to find the sum of interior angles in the figure. We plug the values in: (8-2)*180 = 6*180 degrees = 1080 degrees. We divide this by 8 to get the measure of an interior angle: 1080 degrees/8 = 135 degrees. Since all the interior angles of a regular polygon are congruent, we can say that angle x + angle y = 360 degrees. Thus subtract x degrees from 360 degrees to get y: 360 degrees - 135 degrees = 225 degrees. Therefore, x = 135 degrees and y = 225 degrees.

Given an exponential function for compounding interest, A(x) = P(.95)x, what is the rate of change?
statuscvo [17]

Answer:

Option 3

The rate of change is -5%                

Step-by-step explanation:

Given : An exponential function for compounding interest, A(x) = P(.95)^x

To find : What is the rate of change?

Solution :

The general form of an exponential function is:

f(x) = a(1+r)^x

Where, a is the initial amount,

(1+r) is the rate of change,

r is the growth or decay factor

We have given, A(x) = P(.95)^x

Rate of change is

1+r=0.95

r=0.95-1

r=-0.05

Convert to percent,

r=-0.05\times 100=-5\%

Therefore, Option 3 is correct.
