Step-by-step explanation:
If we consider the right angled triangle,
we can use the pythagarus theorem and find the answer.
Hi there!

f(x) = 2(1/5)ˣ
Recall the form of an exponential function:
f(x) = a(b)ˣ where:
a = initial value
b = rate of decay/growth
If b > 1, the function is undergoing exponential growth. If b < 1, then the function is undergoing exponential decay.
1/5 < 1, so the function is undergoing exponential decay, not growth.
Isolate the variable by dividing each side by factors that don't contain the variable I believe the correct answer is 1. c=ab-da
Well you can combine like terms. 3x-5=1/4x and that's as far as I got hope this helps. sorry I didn't get all the way through
