Step-by-step explanation:
g(r) = 25 - 3r
When r = 4, g(4) = 25 - 3(4) = 25 - 12 = 13.
Answer:
[tex]\boxed{\pink{\sf The\ required\ answer\ is\ 13 .}}[/tex]
Step-by-step explanation:
According to the Question , a function is given to us which is ,
[tex]\implies g(r) = 25 - 3r [/tex]
And we need to find the value of g(4) . So , substituting r = 4 , we have ;
[tex]\implies g(r) = 25 - 3r \\\\\implies g(4) = 25 - 3(4) \\\\ \implies g(4) = 25 - 12 \\\\\boxed{\red{\tt\implies g(4) = 13 }}[/tex]
Hence the required answer is 13.

Find the value of T.
A. 12 B. 5 C. 4 D. 16
the points (-5,4)and (1,r) lie on a line with slope -1. Find the missing coordinates r.
Answer:
R has to be -2
Step-by-step explanation:
So to find a slope the formula is written as
Y2-Y1/ X2 -X1
We know X1 and X2 and Y1.
If we plug those in and put Y2 as the variable ”r”
You’ll get
[tex]\frac{r-4}{1+5}[/tex]
Now make that equal to -1 since thats the slope
If you solve the equation it should get you -2

sheet at the start of the match. If zero or one Libero is designated on the line-up sheet, the coach may select a different Libero for subsequent sets, but may not have two Liberos. If two Liberos are designated on the line-up sheet for Set 1, those are the only two Liberos who may play for that team for the match. b.
Step-by-step explanation:
No. Whether a team designates one or two Liberos for the start of the match, the player(s) designated as Libero prior to the match will be the only players who may participate as a Libero in the match, except in the cases where re- designation is permitted

Step-by-step explanation:
For f(x) = 4x + 1 and g(x) = x ^ 2 - 5 , find (f o g)(4)
Step-by-step explanation:
(f o g)(x)
= f(x² - 5)
= 4(x² - 5) + 1
= 4x² - 19.
Therefore (f o g)(4) = 4(4)² - 19 = 64 - 19 = 45.
Answer:
[tex]\boxed {\boxed {\sf 45}}[/tex]
Step-by-step explanation:
When solving a composition of function composition, work from the inside to the outside.
We have the composition:
(f o g)(4)We must start on the inside, and find g(4) first.
1. g(4)
The function for g is:
[tex]g(x)=x^2-5[/tex]
Since we want to find g(4), we have to substitute 4 in for x.
[tex]g(4)=(4)^2-5[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition, and Subtraction. First we should solve the exponent.
(4)²= 4*4= 16[tex]g(4)=16-5[/tex]
Subtract 5 from 16.
[tex]g(4)= 11[/tex]
Now, since g(4) equals 11, we have:
(f o g)(4)= f(11)2. f(11)
The function for f is:
[tex]f(x)= 4x+1[/tex]
We want to find f(11), so substitute 11 in for x.
[tex]f(11)= 4(11)+1[/tex]
Solve according to PEMDAS and multiply first.
[tex]f(11)= 44+1[/tex]
Add.
[tex]f(11)= 45[/tex]
(f o g)(4) is equal to 45.
what type of transformation is described by (x,y)-(x+2,y+3)
Answer:
reflection across the x axis.
Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

will mark brainliest ~ Select the correct answer. Which function is the inverse of f(x)= x^2 – 16 if the domain is
[tex]x \geqslant 0[/tex]
Step-by-step explanation:
y = x² - 16
x² = y + 16
x = sqrt(y + 16) as x is non-negative.
Therefore f^-1(x) = sqrt(x + 16). (A)

A box of cereal has a width of 4 inches, and a length of 8 inches and a height of 12 inches. What is the volume of the box, in cubic inches?
A box has a width of 4 inches, a length of 8 inches, and a height of 12 inches.
Use the formula V = l w h, where V represents the volume, l represents the length, w represents the width, and h represents the height.
Answer:
Volume=384 inches squared
Step-by-step explanation:
Multiply the width to the length. Therefore it would be 32. Next you multiply 32 to your height, giving you an answer of 384
Simple. 12in cubed.
Also if u wanted me to be VERY specific as to what 12in cubed equals it would be 1728.
What is the equation of the line that passes through the point (4,5) with a zero slope?
Answer:
x=5
Step-by-step explanation:
Since there is no slope, there must be a constant y.
The constant y for this coordinate is 5.
When we have the equation x=5, that creates a straight line through all coordinates with 5 as a y-value.
1) Graph the quadratic function given in standard form and identify the key features. Include at least 5 points on your
graph.
y = -x2 - 2x + 1
Axis of Symmetry:
Vertex:
Y-intercept:
Domain:
Range:
Answer:
Please find attached the graph of the quadratic function is created using Microsoft Excel
1) The line of symmetry is x = -1
2) The vertex is (-1, 2)
3) The y-intercept is (0, 1)
4) The domain is -∞ ≤ x ≤ ∞
5) The range is 2 ≥ y ≥ -∞
Step-by-step explanation:
The given equation is y = -x² - 2·x + 1
The general vertex form is y = a·(x - h)² + k
h = -b/(2·a) = 2/(-2) = -1
k = f(h) = -(-1)² - 2×(-1) + 1 = 2
Therefore;
1) The line of symmetry goes through the vertex and the line of symmetry is x = -1
2) The vertex = (h, k) = (-1, 2)
3) The y-intercept is the coordinate of the point where x = 0 which is (0, 1)
4) The domain are the possible x-values, therefore, the domain = -∞ ≤ x ≤ ∞
5) The range is the possible values y-values.
From the graph, we have the range = 2 ≥ y ≥ -∞
The graph of the quadratic function is created using Microsoft Excel by generating y-values based on the equation and using the graphing function to insert a two dimensional graph of the generated combination of x and y values as shown in the attached figure.

Ruth is at the park standing next to a slide.
Ruth is 5 feet tall, and her shadow is 3 feet
long. If the shadow of the slide is 7.5 feet
long, what is the height of the slide? Assume
the triangles are similar.
Answer:
The slide is approximately 12.75 feet.
Step-by-step explanation:
We know that Ruth is 5 feet tall, and her shadow is 3 feet tall.
5 ÷ 3 = 1.7 when rounded to the nearest tenth
Therefore, the shadow height of an object multiplied by 1.7 is the height of the actual object.
If the shadow of the slide is 7.5 feet, we need to multiply 7.5 by 1.7.
7.5 x 1.7 = 12.75
Therefore, the slide is approximately 12.75 feet.
Hope this helps! :D
Find the distance between the two points. Write your answer as a decimal rounded to the hundredths place if needed.
(-9,1) and (-10, -11)
Answer:
12.04Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x_1 - x_2})^{2} + ({y_1 - y_2})^{2} } \\[/tex]
From the question we have
[tex]d = \sqrt{ ({ - 9 - - 10})^{2} + ({1 - - 11})^{2} } \\ = \sqrt{ ({ - 9 + 10})^{2} + ({1 + 11})^{2} } \\ = \sqrt{ {1}^{2} + {12}^{2} } \\ = \sqrt{1 + 144} \\ = \sqrt{145} \: \: \: \: \: \: \: \: \\ = 12.041594[/tex]
We have the final answer as
