Consider these functions: f(x) = 3x3 + 8x − 2 k(x) = 4x What is the value of k(f(x))? A. 192x3 + 8x − 2 B. 192x3 + 32x − 2 C. 12x3 + 32x − 2 D. 12x3 + 32x − 8
Answers
Answer:
D. 13x3+32x-8
I hope this help
The value of k(f(x)) is 12x³+32x-8. Therefore, option D is the correct answer.
The given functions are f(x)=3x³+8x-2 and k(x)=4x.
We need to find the value of k(f(x)).
What is the function?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
Now, k(f(x))=4(3x³+8x-2)=12x³+32x-8
Therefore, option D is the correct answer.

Answers
Answer:
Step-by-step explanation:
Those standing is the same thing as people who didn't have seats.
Those standing = the total number of people attending - those seated.
Those standing = 5609 - 3800

A man 6 feet tall casts a shadow that is 11 feet long. A building casts a shadow of 139 feet long. The building is tall. Round your answer to the nearest 10th
Answers
Given:
Height of man = 6 ft
Height of man's shadow = 11 feet
Height of building's shadow = 139 feet
To find:
The height of the building.
Solution:
We know that the heights of the objects and there shadows are always proportional.
[tex]\dfrac{\text{Height of man}}{\text{Height of man's shadow}}=\dfrac{\text{Height of the building}}{\text{Height of building's shadow}}[/tex]
Let x be the height of the building.
[tex]\dfrac{6}{11}=\dfrac{x}{139}[/tex]
Multiply both sides by 139.
[tex]\dfrac{6}{11}\times 139=x[/tex]
[tex]\dfrac{834}{11}=x[/tex]
[tex]75.8181...=x[/tex]
[tex]x\approx 75.8[/tex]
Therefore, the building is 75.8 feet long.

Answer:
Let's solve your equation step-by-step.
11x − 2x + 15 = 8 + 7 + 9x
Step 1:
Simplify both sides of the equation.
11x − 2x + 15 = 8 + 7 + 9x
11x + −2x + 15 = 8 + 7 + 9x
( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )
( Combine Like Terms )
9x + 15 = 9x + 15
9x + 15 = 9x + 15
Step 2:
Subtract 9x from both sides.
9x + 15 − 9x = 9x + 15 − 9x
15 = 15
Step 3:
Subtract 15 from both sides.
15 − 15 = 15 − 15
0 = 0

A) 10
B) -2
C) -17

The graph of h(x) = x² was transformed to create the graph of k(x) = -1/7x²? Which of these describes the transformation from the graph of h to the graph of k?
A.) A reflection over the x-axls and a vertical stretch
B.) A reflection over the x-axis and a vertical compression
C.) A reflection over the y-axis and a vertical compression
D.) A reflection over the y-axis and a vertical stretch
Answers
Given:
The functions are:
[tex]h(x)=x^2[/tex]
[tex]k(x)=-\dfrac{1}{7}x^2[/tex]
To find:
The transformation from the graph of h to the graph of k.
Solution:
The transformation is defined as
[tex]k(x)=ah(x+a)=[/tex] .... (1)
Where, a is stretch factor
If 0<|a|<1, then the graph compressed vertically by factor |a| and if |a|>1, then the graph stretch vertically by factor |a|.
If [tex]a<0[/tex], then the graph of h(x) reflected across the x-axis.
We have,
[tex]h(x)=x^2[/tex]
[tex]k(x)=-\dfrac{1}{7}x^2[/tex]
It can be written as
[tex]k(x)=-\dfrac{1}{7}h(x)[/tex] ...(2)
On comparing (1) and (2), we get
[tex]a=-\dfrac{1}{7}<0[/tex]
The graph of h(x) reflected across the x-axis.
[tex]|a|=\dfrac{1}{7}<1[/tex]
So, the graph is compressed vertically.
It means the graph of h reflection over the x-axls and a vertical stretch to get the graph of k.
Therefore, the correct option is B.

first image -2.4/3, second image the x intercept is 28, and it represents the time it takes to totally empty the pool
Step-by-step explanation:
the rate of change, or slope, of an equation is the change in y over the change in x. 11-13.4 = -2.4 and 5-2 =3
the x intercept is the x value when y = 0, so 28 in this case. the question is graphing the total volume of a pool and how long it takes to empty it, so when the pool has no water left in it then that's how long it takes to empty

In ΔSTU, the measure of ∠U=90°, TS = 65, UT = 56, and SU = 33. What ratio represents the cosine of ∠S?
Answers
Answer:
33/65
Step-by-step explanation:
Given the following
∠U=90°,
TS = 65 = HYpotenuse
UT = 56 = Opposite
SU = 33 = Adjacent
Cos <S = adj/hyp
Cos <S = SU/TS
Cos <S = 33/65
Hence the required ratio is 33/65
