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.

x = ×-3/4

because you hace the variable x and you do not know the number of fruit snacks he ate and you need to have the same variables to properly find the answer.

Use the Pythagorean Theorem to find the missing length in the right triangle

Gelneren [198K]

Answer:

it depends

Step-by-step explanation:

If 17 is the hypotenuse

$c=17\\\\b=12\\\\a=?\\\\c^{2} =a^2+b^2\\\\17^2=a^2+12^2\\\\17^2-12^2=a^2\\\\(17-12)(17+12)=a^2\\\\5(27)=a^2\\\\a=\sqrt{9*3*5} \\\\a=3\sqrt{15} \\\\a=11.6$
