What is the range of the function g for the given domain?
g(x) = 2x - 5
D = (-2, 0, 2, 4)
Answer:
R = {-9, -5, -1, 3}
Step-by-step explanation:
To find the range, plug in each value of the domain into the given equation for x.
g(-2) = 2 (-2) - 5 = -9
g(0) = 2 (0) - 5 = -5
g(2) = 2 (2) - 5 = -1
g(4) = 2 (4) -5 = 3
Answer:
R = {-9, -5, -1, 3}
Step-by-step explanation:
We can determine the range of the function g by inputting each given domain value into the function itself.
g(x) = 2x - 5 and D = {-2, 0, 2, 4}
g(-2) = 2(-2) - 5 = -4 - 5 = -9
g(0) = 2(0) - 5 = 0 - 5 = -5
g(2) = 2(2) - 5 = 4 - 5 = -1
g(4) = 2(4) - 5 = 8 - 5 = 3
Therefore, R = {-9, -5, -1, 3}.

What is the range of the function 2x + y = 7
if the domain is {-4, -2,0, 5, 7)?
Answer| range: {15, 11, 7, -3, -7}
Step-by-step explanation:
Plug in the domain to find the range:
x = 4
2(-4) + y = 7
-8 + y = 7
y = 15
x = -2
2(-2) + y = 7
-4 + y = 7
y = 11
x = 0
2(0) + y = 7
0 + y = 7
y = 7
x = 5
2(5) + y = 7
10 + y = 7
y = -3
x = 7
2(7) + y = 7
14 + y = 7
y = -7
Can anybody help me solve for surface area?
(Formula=add all the areas of the faces)
Answer:
230.3cm^2
Step-by-step explanation:
surface area: sum of all faces
base: 12 x 2.5 = 30cm^2
back: 84 cm ^2
cross section x 2 = 7 x 2.5 = 17.5
use Pythagoras theorem to find the width of slope: 7^2 + 2.5^2 = 49 + 6.25 = 55.25. square root of 55.25 = 7.4
so, area of slope : 7.4 x 12 = 88.8cm^2
sum of all areas: 114 + 106.3 = 230.3

The value of x in the the two-step equation is -6.80.
What is the value of x in the equation?In order to determine the value of x, take the following steps:
The first step is to combine similar terms together:
3/4x = -6.821 + 1.72
Add similar terms
3/4x = -5.101
Divide both sides of the equation by 4/3
x = -6.80

What is the square root of 25?
Show your work
Answer:
5
Step-by-step explanation:
The square root of a number is basically that number multiplied by itself.
for example, the square root of 4 is 2 because 2 x 2 is 4
the square root of 25 is 5 because 5 x 5 = 25
Answer:
root 25 = 5
Step-by-step explanation:
because when we will do the prime factorisation then at your left side 5x5 will come aand at right side will come so, 5x5 = 25 .

An athletics squad trains on a long straight track with dots marked at 10m intervals. The coach sets out cones on some of the dots for the squad's sprint training drills. She wants the squad to be able to run any distance which is a multiple of 10m, up to some maximum distance which depends on the number of cones.
Explain why it is not possible to place four cones A, B, C, D, in a line so that each multiple of 10m up to 70m can be run between two of the cones.
Answer:
There are 6 ways to run 10 m between two cones of the four cones giving a maximum available distance to run as 60 meters
Step-by-step explanation:
The parameters given are
Distance between two cones = 10 m
Number of cones = 4
Therefore, number of ways to choose two 10 m distances (distance between two cones) from the four cones = [tex]\binom{4}{2}[/tex] = 6
Hence there are only six 10 m distances to run between two cones which gives a maximum distance available to run as 60 m.

The length, width, and height of Richards Fish tank are 24 inches 16 inches and 18 inches,respectively. Richard is filling his fish tank with water from a hose at the rate of 500 cubic inches per minute. How long will it take to the nearest minute to fill the tank to a depth of 15 inches
Answer: 12 minutes
Step-by-step explanation:
Volume of water in the tank
l x b x h = 24 * 16 * 15 = 5760 cu. in.
Time it will take to fill the tank
= 5760 / 500 = 11.52 = 12 minutes
what is the leading coefficient of the polynomial f(x) defined below:
Explanation:
The leading term of a polynomial is the term with the largest exponent, which in this case that exponent is 4. So the leading term is -3x^4.
The leading coefficient is the coefficient of the leading term. The coefficient of the term -3x^4 is -3.
If the polynomial is written in standard form, then the process is as simple as reading the first coefficient. Otherwise, you may have to sort the terms out first.

Find the percent increase in volume when 1 foot is added to each dimension of the prism. Round your answer to the nearest tenth of a percent. Percent increase ≈ %
Answer:
The percentage increase in volume of the prism is impossible to find. This is because the current dimension or the diagram from which the dimension of the prism could be determined is not given.
However I will explain the methods to follow in finding this percentage increase, assuming that the current dimension of the prism is given.
Step-by-step explanation:
Assuming the volume the of prism is x ft³. After adding 1 ft to each dimension, the volume becomes y ft³.
The percentage increase = (y/x) × 100
= z%
That is,
Percentage increase = [(New volume) ÷ (Old volume)] × 100
The resulting value, z% is the percentage increase.

A quadrilateral-shaped land property is drawn on a coordinate grid. Two adjacent sides of the property lie along the lines y = 4x + 8 and y = – 0.25x – 9, with one corner of the property at the intersection point P of the lines. One of these sides ends at an oak tree located at (–1, 4) and the other side ends at a pine tree located at (4,–10).
What are the coordinates of the point where the two lines intersect?
Answer:
P(-4,-8)
Step-by-step explanation:
Given two lines:
[tex]y = 4x + 8;$ and $ \\y = -0.25x - 9[/tex]
To determine the point of intersection P of the lines, we equate the two lines and solve for (x,y).
[tex]4x + 8= -0.25x - 9\\4x+0.25x=-9-8\\4.25x=-17\\$Divide both sides by 4.25$\\x=-4\\$Recall:$\\y = 4x + 8\\=4(-4)+8\\=-16+8\\=-8[/tex]
Therefore, the intersection point P of the lines is: P(-4,-8)

Brenda collected this data from an experiment.
For the line of fit h = 0.6t + 0.44, what is the residual of the data point at t = 11?
Answer:
7.04
Step-by-step explanation:
To get the value of residual of the data point, we simply substitute 11 for t
The substitution equation is h = 0.6t + 0.44
Substituting 11, we have
h = 0.6(11) + 0.44
h = 6.6 + 0.44
h = 7.04
Answer:
The residual of the data point h = 0.6t + 0.44, is h = 7.04.
Step-by-step explanation:
Given the line of fit, h = 0.6t + 0.44, which Brenda collected from an experiment, at the point t = 11, the residual of the data point is obtained by replacing t with 11 in the given equation h = 0.6t + 0.44.
Doing this, we have
h = 0.6(11) + 0.44
h = 6.6 + 0.44
= 7.04
This is what we want to obtain.
