Answer:
A
Step-by-step explanation:
The greatest common factor of 16 and 12 is 4
The greatest common factor of x² and x is x
Thus combining the 2 gives 4x as the greatest common factor
Answer:
2
Step-by-step explanation:
Given
f(x) = | x - 4 | - 9, then
f(- 7) = | - 7 - 4 | - 9
= | - 11 | - 9 ( absolute value returns a positive value )
= 11 - 9
= 2
Answer:
15
Step-by-step explanation:
8+9.8x+9=7.6x-16
17+9.8x=7.6x-16
33+9.8x=7.6x
33=-2.2

Answer:
Below in bold.
Step-by-step explanation:
(a) Volume = volume of the cylinder + volume of hemisphere
= pi r^2 h + 1/2 * 4/3 pi r^3
= pi 2^2 3 + 2/3 pi 2^3
= 12pi + 16pi/3
= 52pi/3
= 52pi/3 in^3
= 54.45 in^3 to nearest hundredth.
(b) Surface area = area of base + area of curved part + area of the hemisphere
= pi 2^2 + 3 * 2pi 2 + 2 pi 2^2
= 4pi + 8 pi + 12pi
= 24pi in^2
= 75.40 to nearest hundredth.
This one was a little more complex. I factored in 6 to get rid of fraction since standard for is just integers. Then I followed the steps from before.
