Answer:

f(3) = 12

Step-by-step explanation:

f(x) = 2x - 12 + 2x²

f(3) = 2(3) - 12 + 2(3)²

f(3) = 6 - 12 + 2(9)

f(3) = -6 + 18

f(3) = 12

Remember that x=3 is being substituted into the equation, so you can apply this to any function rule problem for any value of x.

What value, written as a decimal, should lena use as the common ratio? 1.0 1.5 2.5 2.0
mariarad [96]

The Lena has no common ratio for the sequence 1.0 1.5 2.5 2.0

According to the question,

1.0  1.5  2.5  2.0

a = 1.0

r = 1.5/1 = 1.5

r = 2.5/1.5 = 1.6667

r = 2/2.5 = 0.8

MatroZZZ [7]

Answer:

207 cubic centimeters

Step-by-step explanation:

Given

volume of cone  = 9 cubic centimeters

Since the cone and cylinder above have the same radius, r, and height, h, then r = h

volume of the cone = 1/3πr²h

69 =  1/3πr²h

πr²h = 69*3

πr²h = 207cubic cm

Since the volume of the cylinder =  πr²h

Hence volume of the cylinder is 207 cubic centimeters
