Answer:
2x² + 6
Step-by-step explanation:
f(g(x)) = 2(g(x))
= 2(x² + 3)
= 2x² + 6
Answer:
D). 659.73 in^3.
Step-by-step explanation:
The volume of a cone = 1/3 π r^2 h
The volume of the large cone = 1/3 π 6^2 * 20 in^3.
The plane passes through the midpoint of the cone so the height of the small cone = 10 in
and the radius of this cone is 1/2 * 6 = 3 in.
The volume of the small cone = 1/3 π 3^2 * 10 in^3.
So the volume of the blue section
= 1/3 π 6^2 * 20 - 1/3 π 3^2 * 10
= 659.73 in^3.
Answer:x
2−14x+40=0 Factor x2−14x+40 using the AC method.(x−10)(x−4)
0 If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.x−10=0x−4=0 Set the first factor equal to 0 and solve.x=10Set the next factor equal to 0and solve....x=4
The final solution is all the values that make (x−10)(x−4)=0 true x=10,4

Answer:
The last package having 18 ounce beans in $6.30 is best to buy.
Step-by-step explanation:
Given that:
A 7-ounce package costs $2.52
for 1 ounce it will cost = $2.52/7
1 ounce will cost = $0.36
A 15-ounce package costs $5.55
for 1 ounce it will cost = $5.55/15
1 ounce will cost = $0.37
An 18-ounce package costs $6.30.
for 1 ounce it will cost = $6.30/18
1 ounce will cost = $0.35
So the last package having 18 ounce beans in $6.30 is best to buy.
i hope it will help you!
