Option B. It represents a nonlinear function because its points are not on a straight line.
What is linear and non-linear functions?
When plotted on a graph, a linear function produces a straight line. Therefore, any non-linear functions are those that are functions. The quickest way to tell if a function is linear or non-linear is probably by graphing it, but we can also tell if a function is linear by looking at its input/output table or equation.
If A(0, 0), B(1, 0) and C(2, 4).
We know that,
If point A,B and C are on a straight line then the slope of AB must be equal to the slope of AC
The formula to calculate the slope between two points is equal to
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Find the slope AB
A(0, 0) and B(1, 0)
[tex]m = \frac{0-0}{1-0} = 0[/tex]
Find the slope AC
A(0, 0) and C(2, 4)
[tex]m = \frac{2-0}{4-0} = \frac{1}{2}[/tex]
Slope of AB ≠ Slope of AC
Points A, B and C are not on a straight line.
Hence, it represents a nonlinear function because its points are not on a straight line.

Find the volume of a pyramid with a square base, where the perimeter of the base is 8.6 cm and the height of the pyramid is 8.1 cm. Round your answer to the nearest tenth of a cubic centimeter.
Answer: 12.5 CC
Step-by-step explanation:
V=1/3Bh where B is the area of the base and h is the height
The perimeter of the square base is 8.6 so each side is 2.15 and the area of the base is (2.15)^2 or 4.6225
V=1/3(4.6225)(8.1)=12.5cc

Jenny used a total of 3 5/6 gallons of gas while driving her car. Each hour she was driving, she used 7/9 gallons of gas. What was the total number of hours she was driving?
Answer:
Jenny drove for about 4.93 hours
Step-by-step explanation:
Jenny uses 7/9 gallons of gas per hour.
She used a total of 3 5/6 gallons.
If x is the number of hours she drove, then she used 7x/9 gallons.
X* 7/9 = 3 5/6
3 5/6 can be converted to an improper fraction.
((3*6)+5) / 6 = 23/6 gallons
=> x * 7/9 = 23/6
=> x = (23/6) / (7/9)
=> x = (23/6) * (9/7)
=> x = 69/14
=> x = 4.928571429 hours.

Find k so that x + 2 is a factor of x ^ 3 - k * x ^ 2 + 2x + 7k. (If anyone could help me out with this that would be amazing!!)
Answer:
k = 4
Step-by-step explanation:
If x + 2 is a factor of the polynomial;
By the factor theorem, if we set x + 2 = 0, then make x the subject of the formula; if we substitute the value into the polynomial, the result we should have after calculating should be zero
So, we have it that;
x + 2 = 0
x = -2
Substitute into the polynomial and equate to zero
(-2)^3 - k (-2)^2 + 2(-2) + 7k = 0
-8 -4k -4 + 7k = 0
-12 -4k + 7k = 0
-12 + 3k = 0
-3k = -12
k = -12/-3
k = 4

Step-by-step explanation:
A street light is 7.5 feet tall casts a 3-foot-long shadow A nearby flagpole casts a 16.5 foot long shadow what is the height of the flag pole
Answer:
h = 41.25 foot
Step-by-step explanation:
Given that,
Height of a street light = 7.5 feet
It casts a 3-foot-long shadow.
A nearby flagpole casts a 16.5 foot long shadow. We need to find the height of the flag pole. Let the height be h. It can be calculated as :
[tex]\dfrac{\text{height of street light}}{\text{height of shadow of street light}}=\dfrac{\text{height of flagpole}}{\text{height of shadow of the flag pole}}\\\\\dfrac{7.5}{3}=\dfrac{h}{16.5}\\\\h=\dfrac{7.5\times 16.5}{3}\\\\h=41.25\ foot[/tex]
So, the height of the flag pole is equal to 41.25 foot.
The height of the flag pole is 41.25 feet tall.
Word problems in mathematics are methods used to solve real-life cases. They usually follow a logical approach with the use of arithmetic operations when solving them.
From the parameters given:
If 7.5 feet tall casts = 3-foot long shadowLet the height of the flag pole be = x
∴
(x) feet tall casts = 16.5 foot long shadow.To determine the height of the flag pole, we have:
[tex]\mathbf{x = \dfrac{7.5 feet \ tall \times 16.5 \ foot \ long} {3 \ foot \ long} }[/tex]
x = 41.25 feet tall

The ground pool for a hot air balloon can see the balloon in the sky at an angle of elevation of 11°. The pilot radios the crew that the balloon is 950 feet above the ground. What is the horizontal distance from the balloon to the ground crew.
Answer:
4,886.83feet
Step-by-step explanation:
The question will result in a right triangle with
Opposite = distance of the balloon above the ground = 950feet
Angle of elevation = 11 degrees
Required
Horizontal distance h (adjacent)
Using SOH CAH TOA identity
Tan theta =opp/adj
Tan 11 = 950/h
h = 950/tan 11
h = 950/0.1944
h = 4,886.83feet
Hence the horizontal distance from the balloon to the ground crew is 4,886.83feet

Answer:
$16.05
Step-by-step explanation:
50% of 10.00
0.50 x 10.00 = 5.00
10.00 + 5.00 = 15.00

Answer:
There are 47 Borogroves and 35 Mome raths
Step-by-step explanation:
Here, given the number of legs, we want to find the number of each type of animals
Let the number of borogoves be b and the number of mome raths be m
From the question, there are 82 creatures;
Thus;
m + b = 82 ••••••••(i)
the total number of legs by b borogroves will be b * 2 = 2b
the total number of legs by m mome raths will be m * 4 = 4m
the sum of all legs is 234
2b + 4m = 234 •••••••••(ii)
From equation 1, m = 82-b
Substitute this into equation ii
2b + 4(82-b) = 234
2b + 328 - 4b = 234
4b-2b = 328-234
2b = 94
b = 94/2
b = 47
Recall;
m + b = 82
m + 47 = 82
m = 82-47
m = 35
Use technology or a z-score table to answer the question.
The scores on a memory test are normally distributed with a mean of 100 and a standard deviation of 25. Consider a group of 400 people who take the test.
How many people will score 90 or less?
63
138
180
262
Answer:138
Step-by-step explanation:
I just took the test
The number of people who score 90 or less is 138, option B is correct.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Let us find the proportion of people in the group of 400 who score 90 or less on the memory test.
Given that the scores are normally distributed with a mean of 100 and a standard deviation of 25.
Using a z-score table, we can find the z-score corresponding to a raw score of 90 as follows:
z = (90 - 100) / 25 = -0.4
The area under the standard normal distribution curve to the left of z = -0.4 is 0.3446, which represents the proportion of people who score 90 or less on the memory test.
Therefore, the number of people who will score 90 or less is:
0.3446 x 400 = 137.84
Hence, the number of people who score 90 or less is 138, option B is correct.
