Step-by-step explanation:
we know that
The equation of a exponential decay function is given by
where
a is the initial value
r is the rate of decrease
we have
Convert to percentage

Answer:
Undefined
Step-by-step explanation:
This equation is just a vertical line, so the slope is undefined.
c=52, a=2b+8
<span>
Pythagorean Theorem = a^2+b^2=c^2</span>
<span>
(2b+8)^2+b^2=52^2</span>
<span>
<span>
4b^2+32b+64+b^2=2704</span></span>
<span><span>
5b^2+32b-2640=0 </span></span>
<span>
b=20 </span>
a= 2(20)+8 =
48
<span>48+20+52
= 120</span>
