Answer:
B. {(x, y): y = x²}
Step-by-step explanation:
A function is a graph where every input (x-value) has one and only one output (y-value). In other words if the value for x=2, there will only be one corresponding point for y. For the function in B, that y-value would be 4. Both A and D, solve for y, means taking the square root which leaves a +/- x-value. C is absolute value of y, which means the positive and negative values for y would have the same point. Only choice B has x-values corresponding to a singular y-value. If you can remember what these graphs look like you can test if they are functions based on the vertical line test.

Answer:
[tex]A' = (0,20)[/tex]
[tex]B' = (16,12)[/tex]
[tex]C' = (8,4)[/tex]
Step-by-step explanation:
Given
[tex]A = (0,10)[/tex]
[tex]B =(8,6)[/tex]
[tex]C=(4,2)[/tex]
[tex]k = 2[/tex] --- scale factor
Required
The coordinates of A'B'C'
This is calculated as thus:
[tex]A'B'C' = ABC * k[/tex]
So, we have:
[tex]A' = (0,10) * 2[/tex]
[tex]A' = (0,20)[/tex]
[tex]B' = (8,6) * 2[/tex]
[tex]B' = (16,12)[/tex]
[tex]C' = (4,2)*2[/tex]
[tex]C' = (8,4)[/tex]

Find the 55 ^ (th) term of the following arithmetic sequence .
4, 11, 18, 25, ...
Answers
To get the 2nd term, add 7 to the first term: 4 + 7 = 11
To get the 3rd term, add 7 to the second term: 11 + 7 = 18
Put another way, add 7 twice to the first term: 4 + 2*7 = 18
Similarly, get the 4th term by adding 7 to third term, or add 7 three times to the first term: 18 + 7 = 25, or 4 + 3*7 = 25.
Following the pattern, the n-th term of the sequence is obtained by adding n - 1 copies of 7 to the first term. So the 55th term is 4 + 54*7 = 382

Enter the value of b when the expression 9x + b is equivalent to
3(3x + 1).
BE
ker notes
Answers
Answer:
b = 3
Step-by-step explanation:
Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other:
First, distribute 3 to all terms within the parenthesis:
3(3x + 1) =
3 * 3x = 9x
3 * 1 = 3
9x + b = 9x + 3
Isolate the variable, b. Subtract 9x from both sides:
9x (-9x) + b = 9x (-9x) + 3
b = 3
3 is your value for b.

The variable y varies directly as x. When x = 20, y = 12. What is the value of y when x = 15?
A. 7
B. 9
C. 18
D. 25
Answers
The value of y when x = 15 is 9
VariationIf the variable y varies directly as x, this is expressed as;
y = kx
where k is the constant of proportionality
If x = 20 when y = 12, then;
k = y/x
k = 12/20
If x = 15, then the value of y is;
y = 12/20*15
y = 9
Hence the value of y when x = 15 is 9

what is the value of angle x?
Answers
Answer:
x=66
Step-by-step explanation:
Hello There!
∠BAC ≅ ∠CDB because in a parallelogram opposite angles are congruent
So all we have to do is solver for ∠BAC
Remember the sum of the triangles angles is 180 so to find ∠BAC
we subtract the given angles (83 and 31) from 180
180-83-31=66
so ∠BAC = 66
like stated before
∠BAC≅∠BDC so if ∠BAC = 66 then x also equals 66
Answer:
x = 66

A parallelogram is shown below:
A parallelogram ABCD is shown with DC equal to 9 feet and the perpendicular distance between AB and DC equal to 8 over 9 foot.
Part A: What is the area of the parallelogram? Show your work. (5 points)
Part B: How can you decompose this parallelogram into two triangles? If this parallelogram was decomposed into two triangles, what would be the area of each triangle? (5 points)
Answers
Answer:
a). Area of the parallelogram = 8 cm²
b). Area of both the triangles = 4 cm²
Step-by-step explanation:
a). Area of the given parallelogram ABCD = Base × Height
= DC × (Vertical distance between
AB and DC)
= 9 × [tex]\frac{8}{9}[/tex]
= 8 ft²
b). If we decompose this parallelogram into two triangles ΔABC and ADC by a diagonal AC,
Area of both the triangles will be equal.
(Since, diagonal of a parallelogram divides the parallelogram into two equal triangles)
Therefore, area of ΔABC = Area of ΔADC = 4 ft²

Trucks in a delivery fleet travel a mean of 90 miles per day with a standard deviation of 36 miles per day. The mileage per day is distributed normally. Find the probability that a truck drives less than 118 miles in a day. Round your answer to four decimal places.
Answers
Answer:
0.7823 = 78.23% probability that a truck drives less than 118 miles in a day.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Trucks in a delivery fleet travel a mean of 90 miles per day with a standard deviation of 36 miles per day.
This means that [tex]\mu = 90, \sigma = 36[/tex]
Find the probability that a truck drives less than 118 miles in a day.
This is the pvalue of Z when X = 118. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{118 - 90}{36}[/tex]
[tex]Z = 0.78[/tex]
[tex]Z = 0.78[/tex] has a pvalue of 0.7823
0.7823 = 78.23% probability that a truck drives less than 118 miles in a day.
If 9% of a number equals 10, find 90% of that number.
