Answer:
Step-by-step explanation:
perimeter = 2(4ft+7ft) = 2*11ft = 22ft
We want to determine the domain of

any function of the form

is called an "exponential function",
the only condition is that b is positive and different from 1, and a is a nonzero real number.
The domain of such functions is all real numbers.
That is for any x, the expression <span>3(2^-x) "makes sense".
Answer: </span><span>The domain is all real numbers</span>
I am not sure but I would say either step 2 or 4 but I am not 100% sure I hope you do well. Good Luck:)
3c/5-1/2=-31/2 Add 1/2 both sides
+1/2 +1/2
3c/5=-30/2 Then simplify the fraction
(5)3c/5=-15(5) Multiply 5 both sides
3c=75 Finally, divide by 3 both sides
c=25
So the answer to your question is E.
