Answer:
C. F(x)= 2^x + 1
Step-by-step explanation:
Step 1: Substitute x into the various various functions.
Putting x into F(x)= 2^x + 1
When x= 1, 3 and 8 respectively.
when x =1
F(1)= 2¹ + 1 = 3
when x =3
F(3)= 2³ + 1 = = 8+1 =9
when x =8
F(8)= 2^8 + 1 = 256 +1 = 257
The correct equation is to substitute for x is F(x)= 2^x + 1
Answer:
First, add the two mixed numbers together.
Combine the equation and number.
4 2/7
Therefore, the answer is 1/2
Prism volume = lbh
= 10*8*12
= 960cm^3
Note: I'm assuming the hole was cut right through it...
Hole volume = lbh
= 2*3*12
= 72cm^3
Final volume = 960 - 72 = 888cm^3
