a = 40° (vertical angles are equal)

b = 90 - 40 = 50° (sum of all interior angles in a triangle is equal 180 but one angle is 90° so a + b = 90°)

c = 180 - 65 = 115° (angle c and 65° are supplementary angles, so sum = 180°)

Pls help: without graphing determine whether the function represents exponential growth or exponential decay. Then find y-interc

Mrac [35]

Given

$0.99(\frac{1}{3})^x$

To determine whether the function represents exponential growth or exponential decay, and the y-intercept.

now,

It is given that,

$0.99(\frac{1}{3})^x$

The exponential functions are of the form,

$y=ab^x$

If a is positive and b is greater than 1, then it represents exponential growth.

And, if a is positive and b is greater than 0 and less than 1, then it represents exponential decay.

Since b=1/3<1.

Then, the given function represents exponential decay.

The y- intercept of the function is,

$\begin{gathered} y=0.99(\frac{1}{3})^x \\ \text{When x=0.} \\ y=0.99(\frac{1}{3})^0 \\ y=0.99 \end{gathered}$

Hence, the y-intercept is 0.99.
