Answer:
f(-2) = 4
Step-by-step explanation:
f(x) = x²
f(-2) = (-2)² = (-2)(-2) = 4
Answer:
A = 6.13e^(0.00884769t)
Step-by-step explanation:
The exponential growth model can be written two ways. Comparing them, we can find the value of k.
A = 6.13×(7.00/6.13)^(t/(2015-2000)) = 6.13×e^(kt)
Dividing by 6.13 and taking natural logs, we get ...
t/15×ln(7.00/6.13) = kt
k = ln(7.00/6.13)/15 . . . . . divide by t
k ≈ 0.00884769
Then the exponential growth function can be written as ...
A = 6.13e^(0.00884769t)
Answer:
The length of a rectangle is 5 centimetres longer than twice its width. If the perimeter of the rectangle is 88 centimetres, what is the width?
width=x
length=2x+5
perimeter=88=2L+2W
so half perimeter=44=L+W
x+2x+5=44
3x=39
x=13 cm width ANSWER
2x+5=31 cm length
