Answer:
18
Step-by-step explanation:
9*2= 18
18-9=9
because it said twice as old as Robin you multiply
Hope this helped you
You have a base that is 8x8 and the slant height of the triangle is 22.
This is the formula, L=1/2Ph
H = 22 Meters
1. P=2L+2W -> 2(8)+2(8) = 32 meters
2. L= 1/2(32)(22) = 352 meters squared :)
I believe the fourth one is the answer.
Given:
f(x) is an exponential function.


To find:
The value of f(0.5), to the nearest hundredth.
Solution:
The general exponential function is

For, x=-0.5,

...(i)
For, x=1.5,

...(ii)
Divide (ii) by (i).


Taking square root on both sides, we get


Putting b=0.882 in (i), we get




Now, the required function is

Putting x=0.5, we get



Therefore, the value of f(0.5) is 23.81.
