What is the correct answer choice?
Answer:
the answer is J
Step-by-step explanation:
f(x) = (3)^2 - 8 = 9-8-1
f(x)= (7)^2 - 8 = 49 - 8 = 41
1 <= f(x)<= 41
2. The volume of a cylinder varies jointly with its height and the square of the radius. A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. Another spice container is 3 inches tall with a radius of 1.5 inches, what would be the volume?
Answer:
Volume=21.195 cubic inch
Step-by-step explanation:
The volume of a cylinder varies jointly with its height and the square of the radius is expressed as
V∝hr^2
Introducing our constant of proportionality,K we have that
V =Khr^2
Given that A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. We have that
V =Khr^2
7.85=K 2.5 X 1^2
K=7.85/2.5 x1
K=3.14
Given that another spice container is 3 inches tall with a radius of 1.5 inches, Volume=?
V =Khr^2
V=3.14 X 3 X 1.5^2
V=21.195 cubic inch
Find the solutions to x2 = 8.
A. X = +2.2
B. x= 12,4
C. X = +4-2
D. = +4.6
Answer:
x = ± 2√2
Step-by-step explanation:
Assuming "x2" is x^2 or "x squared", the answer can be derived from "square-rooting" both sides.
√ x^2 = √ 8
Then we simplify.
x = ± 2√2

mathematic equation
Answer:
[tex] \frac{0.56}{w - 6} [/tex]
Step-by-step explanation:
1) Simplify 4.8 - 2 to 2.8.
[tex] \frac{2.8}{5(w - 6)} [/tex]
2) Simplify.
[tex] \frac{0.56}{w - 6} [/tex]
Therefor, the answer is 0.56/w-6.

1. (08.01, 8.02 MC) An expression is shown below: 2x3y2 + 18xy2 − 20x2y − 180y Part A: Rewrite the expression so that the GCF is factored completely. (4 points) Part B: Rewrite the expression completely factored. Show the steps of your work. (6 points) (10 points)
Answer:
A. 2y
B. (xy − 10)(2x²y + 18y)
Step-by-step explanation:
Part A: Rewrite the expression so that the GCF is factored completely.
2x³y² + 18xy² − 20x²y − 180y
Factoring y out, we have
(2x³y + 18xy − 20x² − 180)y
Factoring 2 out, we have
(x³y + 9xy − 10x² − 90)2y
So, the GCF is 2y and the expression factored is (x³y + 9xy − 10x² − 90)2y
Part B: Rewrite the expression completely factored.
2x³y² + 18xy² − 20x²y − 180y
Rearranging, we have
2x³y² − 20x²y + 18xy² − 180y
Separating them into brackets, we have
(2x³y² − 20x²y) + (18xy² − 180y)
Factorizing the expressions in bracket, we have
(xy − 10)2x²y + (xy − 10)18y
collecting like terms, we have
(xy − 10)(2x²y + 18y)

Answer: X is less than or equal to 7 (keep the inequality sign you already have)
Step-by-step explanation:
Subtract 11 from 18
18-11 = 7
X is less than or equal to 7
Answer:
OMG i am doing this is school to!! So anyways 11+x< or equal to 18=0.611.
Step-by-step explanation:
Simplify 11/x. Then it should be 11/x-18=0.
What steps do you need to take to solve the equation 7x+6= 18?

A. Subtract 6. Then, multiply by 2.
B. Add 6. Then, multiply by 2.
C. Subtract 6. Then, divide by 2.
D. Add 6. Then, divide by 2.
The probability of rolling a number cube and getting a 6 and 3.
We have to find out the probability of getting 6 and 3,
Since this only one roll it is not possible to get 2 numbers in one roll
So, I will presume you want the probability of getting 6 or 3,
Total number of outcomes= {1,2,3,4,5,6} = 6 outcomes
Number of favorable outcomes = {3,6} = 2 outcomes
Probability of rolling 6 or 3 = [tex]\frac{Number'of 'favorable' outcomes}{Total' number 'of' outcomes}[/tex]
= 2/6
= 1/3 or 0.33333%
Therefore the probability of rolling 6 or 3 is one in three chances

Mr. Carlevato and Mr. Burrows get into a debate about two different expressions. · Mr. Carlevato says "2(2x + 3) is equal to 4x + 6". · Mr. Burrows says "Nope, wrong, those are clearly different expressions" Try substituting x=5 into both expressions. Do you get the same answer for both expressions? Show your work!
Answer:
Yes, the same answer is obtained.
Step-by-step explanation:
According to Mr. Carlevato, [tex]2(2x+3)[/tex] is equal to [tex]4x+6[/tex]. However, [tex]2(2x+3)[/tex] is not equal to [tex]4x+6[/tex] according to Mr. Burrows.
Put [tex]x=5[/tex] in [tex]2(2x+3)[/tex]
[tex]2[2(5)+3]=2(10+3)=2(13)=26[/tex]
Put [tex]x=5[/tex] in [tex]4x+6[/tex]
[tex]4x+6=4(5)+6=20+6=26[/tex]
Therefore,
[tex]2(2x+3)=4x+6[/tex]
Yes, the same answer is obtained.
