Circumference= 2 pi x r
Diameter= 9 (double the radius)
Radius= 4.5
Pi= 3.14
2 x 3.14= 6.28

Please show work. What is the volume of the figure?
Answers
Answer:
Volume = 288 in.³
Step-by-step explanation:
Volume of the solid = volume of the cube + volume of the square pyramid
V = a³ + ⅓*a²*h
a = 6 in.
h = 12 - 6 = 6 in.
Plug in the values into the volume formula
Volume = 6³ + ⅓*6²*6
Volume = 216 + 72
Volume = 288 in.³

Step-by-step explanation:
Given
The three equations
Required
Label the x and y-axes
The general rule is to place the independent variable (x) on the x-axis and the dependent (y) on the y-axis.
What x and y represented are always stated after writing the equation.
So, we have:
[tex](a)\ y = x + 5[/tex]
[tex]x \to[/tex] Number of chores
[tex]y \to[/tex]Amount
[tex](b)\ y =15x[/tex]
[tex]x \to[/tex] Time (hours)
[tex]y \to[/tex]Miles traveled
[tex](c)\ y = 6x[/tex]
[tex]x \to[/tex] Time (hours)

A cuboid with a volume of 924 cm^3 has dimensions
4 cm, (x + 1) cm and (x + 11) cm.
Find the longest length of the Cuboid.
Answers
Answer:
21
Step-by-step explanation:
Volume of a cuboid is given by
V = l*w*h
924 = 4 (x+1) (x+11)
FOIL
924 = 4(x^2 +11x+x+11)
924 = 4(x^2+12x+11)
Divide each side by 4
231 = (x^2+12x+11)
Subtract 231 from each side
0 = x^2 +12x +11-231
0 = x^2 +12x - 220
Factor
0 = (x+22) (x-10)
Using the zero product property
x+22 =0 x-10 =0
x=-22 x=10
We cannot have a negative length
x=10
The side lengths are 4, 10+1, 10+11
4,11,21
The longest is 21
I need help with this please
Answers
Answer:
B) 9x² + 6x + 1
Step-by-step explanation:
use the FOIL method:
(3x + 1)(3x + 1)
F: 3x(3x) = 9x²
O: 3x(1) = 3x
I: 3x(1) = 3x
L: 1(1) = 1
combine the 'like terms' in the middle to get 6x
answer: 9x² + 6x + 1
Answer:
the answer is B. 9x^2 + 6x+1
Describe how the graph of y= x2 can be transformed to the graph of the given equation. (2 points) y = (x-4)2-8
Answers
Answer:
The description is that the function was translated 4 units to the right and 8 units down.
Step-by-step explanation:
Translations:
Translating a function f(x) a units to the right is the same as finding f(x - a).
Translating a function f(x) a units to the left is the same as finding f(x + a).
Translating a function f(x) a units up is the same as finding f(x) + a.
Translating a function f(x) a units down is the same as finding f(x) - a.
y= x² to y = (x-4)²-8
First at the domain, x becomes x - 4, so f(x) becomes f(x - 4), that is, the function was translated 4 units to the right.
Then the function is subtracted by 8, that is, it was translated 8 units down.
The description is that the function was translated 4 units to the right and 8 units down.

Which equation represents a function of x that is not linear?
Answers
Answer:
y = 4x+3x^2
Step-by-step explanation:
For an equation to be linear, x must have a power of 1
y = 4x+3x^2 has a power of x that is not x ( x^2) so this is not linear ( it is quadratic)
