The value of the function g(x) = 8x² + 4x at g(-4) is 112.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, a function g(x) = 8x² + 4x.
Now to obtain the value of g(-4) we'll simply substitute - 4 in place of x.
which is g(-4) = 8(-4)² + 4(-4).
g(-4) = 8×16 - 16.
g(-4) = 128 - 16.
g(-4) = 112.

Find the height of a cone with a diameter of 12 m and whose volume is 133 m.
A. 2 m
B. 9 m
C. 3 m
D. 1 m
Answer:
D
Step-by-step explanation:
Here, we want to get the height of the cone
radius = diameter/2
r = 12/2 = 6 m
To get this, we use the formula for the volume
V = 1/3 * pi * r^2 * h
133 = 1/3 * 3.142 * 22/7 *6^2 * h
h = 1.12 m
Please do number 16 for me. (With work)
Answer:
m<5 = 75°
Step-by-step explanation:
16. Given:
m<1 = 75°; m<3 = 40°
Required:
m<5
Solution:
Since lines A and B are parallel, and m<1 corresponds to m<5, therefore,
m<1 = m<5 (corresponding angles are congruent)
m<1 = m<5 = 75°
m<5 = 75°

Two angles of a triangle measure 55 and 20 what is the measure of the third angle of the triangle
Answer:
105 degrees
Step-by-step explanation:
well if we take a look at this
we know for sure that every triangle must have a total angle measurement of 180 degrees
so if we take the information we have and we add those together
55 + 20
that will give us
75
then in order to find the missing angle measurement we take the total number of degrees in a triangle and subtract the two angles together from it
180-75
giving us 105 degrees as the third measurement of the angle in the triangle
Answer:
the third measure is [tex]105[/tex]°
Step-by-step explanation:
All measures of a triangle add up to 180°
[tex]A+ B + C = 180[/tex]
[tex]20 + 55 + C = 180[/tex]
[tex]75 + C = 180[/tex]
[tex]C = 105[/tex]°

Choose the graph of the solution to this inequality. c – 12 ≥ –16 A number line with a closed dot at negative 4 shaded to the right. A number line with a closed dot at 4 shaded to the left. A number line with a closed dot at 4 shaded to the right. A number line with a closed dot at negative 2 shaded to the right.
A number line with a closed dot at -4 is shaded to the right. Option A is correct.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
Given inequality,
c – 12 ≥ –16
Add 12 on both sides
c ≥ -4
So the required number line would be as a closed dot at -4 and shaded to the right.
Thus, A number line with a closed dot at -4 is shaded to the right. Option A is correct.

Answer:
Step-by-step explanation:
A jeweler sells a popular line of charm bracelets. Each bracelet includes one chain and a number of charms selected by the customer. The price of the chain is 25 dollars, and each charm costs c dollars. Which expressions represent the price, in dollars, of a charm bracelet with five charms? Select ALL that apply.
Answer:
Price of bracelet = $(25 + 5c)
Step-by-step explanation:
As given,
A bracelet = 1 chain + Number of charm selected by customer
Also given,
Price of chain = $25
Price of each charm = $c
As,
we have to write equation for a bracelet with 5 charm
So,
Price of bracelet = Price of 1 chain + Price of 5 charm
As
Price of 1 charm = $c
⇒Price of 5 charm = $5×c = $5c
∴ we get
Price of bracelet = $25 + $5c = $(25 + 5c)
