Answer:
$133.40
Step-by-step explanation:
First you have to find 15% of 29 which is 4.35. The way I figured this out was 10% of 29 is 2.9 and 5% of 29 is 1.45 and 2.9 + 1.45 = 4.35.
Then you want to add 4.35 to 29 which equals 33.35, her new hourly pay. Multiply 33.35 by the 4 hours she is working and you end up with $133.40.

Felix needs to determine whether x + 3 is a factor of f(x)=−2x4−8x3−2x−63. How can Felix use the factor theorem to determine whether x + 3 is a factor of f(x)? Drag a value, expression, or phrase into each box to correctly complete the statements. Felix evaluates{ } Response area and determines its value to be{ } Response area. Felix concludes that x + 3{ } Response area a factor of f(x)=−2x4−8x3−2x−63.
Answer:
1st Slot: f(-3)
2nd Slot: -3
3rd Slot: is not
Step-by-step explanation:
Using the Remainder Theorem, we plug in the root of x + 3 (which is x = -3) and see the remainder.
If the remainder = 0, it is a factor
If the remainder ≠ 0, it is NOT a factor
f(-3) = -2(-3)⁴ - 8(-3)³ - 2(-3) - 63
f(-3) = -3
So, x + 3 is NOT a factor.
We then have our 3 answers.

You estimate that the driving distance from Raleigh, NC to Charlotte, NC is around 180 miles. When you looked it up on the internet, you found that the actual distance is only 167.5 miles. What was the relative (percent) error of your estimate? In other words, how far off were you from the actual value?
Answer:
7.5%
Step-by-step explanation:
Approximate distance = 180 miles
Actual distance = 167.5 miles
Percent error = { (approximate value - actual value) / actual value } × 100
= { (180 - 167.5) / 167.5 } × 100
= (12.5 / 167.5) × 100
= 0.075 × 100
= 7.5%

The line graph shows the time spent by people visiting the
Department of Motor Vehicles to renew their driver's license during
their birth month. To the nearest minute, what is the average waiting
time for all the months shown on the graph?
A)
18 minutes
B)
29 minutes
C)
37 minutes
D)
41 minutes
Answer:
Option (B)
Step-by-step explanation:
Average waiting time in the month of October = 20 minutes
Average waiting time in the month of November = 30 minutes
Average waiting time in the month of December = 60 minutes
Average waiting time in the month of January = 40 minutes
Average waiting time in the month of February = 10 minutes
Average waiting time in the month of March = 10 minutes
Average waiting time in the month of April = 30 minutes
Average waiting time in the month of May = 40 minutes
Average waiting time in the month of June = 20 minutes
Total waiting period from October to June = 20 + 30 + 60 + 40 + 10 + 10 + 30 + 40 + 20 = 260
Average waiting period = [tex]\frac{260}{9}[/tex]
= 28.89

The area of a rectangle is the product of its length and width. Both length and width are whole numbers. A rectangular poster has an area of 204 square inches. The width of the poster is greater than 10 inches and is prime. What is the width of the poster?
Answer:
The width of the poster will be 17 inches
Step-by-step explanation:
The area = 204 square inches
Note:
- both length and width are whole numbers
- The width of the poster is greater than 11 inches
- The width is a prime
The prime numbers greater than 11 are
13, 17, 19, 23, 29, ...,
all these numbers divide 204 with a remainder except for 17
Therefore, the width will be 17 inches, and the length will be 12
since 17 divides 204 into 12 places

Jason had to replace the floor of a triangular portion of his dining room. The portion had a height that was twice as high as the base. If the total area of the portion he needed to replace was 16 square feet (16ft2),how long in feet was the base of the portion he needed to replace?
Answer:
4 feet
Step-by-step explanation:
We know the the area of a triangle can be represented as [tex]\frac{bh}{2}[/tex].
Since the height is twice the base, we can substitute the value [tex]2b[/tex] in as [tex]h[/tex] in the expression, making it [tex]\frac{b\cdot2b}{2}[/tex]. If the area is 16, we can make the equation
[tex]\frac{b\cdot2b}{2} = 16[/tex]
Now to solve for b.
[tex]\frac{2b^2}{2} = 16\\\frac{2b^2}{2}\cdot2 = 16\cdot2\\\\2b^2 = 32\\\\2b^2\div2 = 32\div2\\\\b^2 = 16\\\\b=4[/tex]

What is equation?A statement of equality between two expressions consisting of variables and/or numbers. In essence, equations are questions, and the development of a mathematics has been driven by attempts to find answers to those questions in a systematic way.
For example
An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. For example, 3x + 5 = 15. There are different types of equations like linear, quadratic, cubic, etc.
Given:
x= 5 ± √16
Now, taking the root of 16 which is +4 and -4.
So, x= 5 ± 4
We have two values ,
x= 5+4 or x= 5-4
x=9 or 1
Hence, the solution to x= 5 ± √16 is B. 1 and C. 9.

What is the vertex of g(x) = 8x2 – 48x + 65? (–3, –7) (3, –7) (24, –7) (–24, –7)
B. (3, -7)
When the equation is graphed, the vertex is at the point (3,-7). I hope this helps!!!
The vertex of the quadratic expression g(x) = 8x² - 48x + 65 is (3, -7).
What are Quadratic Expressions?Quadratic expressions are polynomial expressions of second degree.
The general form of a quadratic expression is ax² + b x + c.
The vertex of a quadratic function f(x) = ax² + b x + c is,
(-b/2a, f(-b/2a)).
Here the function is,
g(x) = 8x² - 48x + 65
b = -48 and a = 8.
Vertex = (-(-48) / 16, g(-(-48) / 16))
= (3, g(3))
g(3) = 8(3)² - 48(3) + 65 = 0
g(3) = -7
Hence the correct option is B.

Convert 43/7 into a proper fractions show work?
Step-by-step explanation:
Hey, there!!
[tex] = \frac{43}{7} [/tex]
Divide 43 by 7.
you will get quotient as 6 and remainder is 1.
so,
The proper fraction is:
[tex] = 6 \frac{1}{7} [/tex]

Question 8 Find the unit vector in the direction of (2,-3). Write your answer in component form. Do not approximate any numbers in your answer.
Answer:
The unit vector in component form is [tex]\hat{u} = \left(\frac{2}{\sqrt{13} },-\frac{3}{\sqrt{13}} \right)[/tex] or [tex]\hat{u} = \frac{2}{\sqrt{13}}\,i-\frac{3}{13}\,j[/tex].
Step-by-step explanation:
Let be [tex]\vec u = (2,-3)[/tex], its unit vector is determined by following expression:
[tex]\hat {u} = \frac{\vec u}{\|\vec u \|}[/tex]
Where [tex]\|\vec u \|[/tex] is the norm of [tex]\vec u[/tex], which is found by Pythagorean Theorem:
[tex]\|\vec u\|=\sqrt{2^{2}+(-3)^{2}}[/tex]
[tex]\|\vec u\| = \sqrt{13}[/tex]
Then, the unit vector is:
[tex]\hat{u} = \frac{1}{\sqrt{13}} \cdot (2,-3)[/tex]
[tex]\hat{u} = \left(\frac{2}{\sqrt{13} },-\frac{3}{\sqrt{13}} \right)[/tex]
The unit vector in component form is [tex]\hat{u} = \left(\frac{2}{\sqrt{13} },-\frac{3}{\sqrt{13}} \right)[/tex] or [tex]\hat{u} = \frac{2}{\sqrt{13}}\,i-\frac{3}{13}\,j[/tex].

[tex]q(x)=2x-5,x\neq-2[/tex]
Step-by-step explanation:
So we have:
[tex]a(x)=2x^2-x-10\\b(x)=x+2[/tex]
And we want to find the quotient q(x). Thus:
[tex]q(x)=\frac{a(x)}{b(x)}[/tex]
Substitute:
[tex]q(x)=\frac{2x^2-x-10}{x+2}[/tex]
Factor the numerator:
[tex]2x^2-x-10\\=2x^2+4x-5x-10\\=2x(x+2)-5(x+2)\\=(2x-5)(x+2)[/tex]
Substitute:
[tex]q(x)=\frac{(2x-5)(x+2)}{x+2}[/tex]
The (x+2)s cancel out. Therefore:
[tex]q(x)=2x-5[/tex]
However, we must restrict x such that it cannot equal -2.
In the original equation, if it did, our answer would be undefined. Thus, our final answer is:
[tex]q(x)=2x-5,x\neq-2[/tex]
And we are done :)

In 1990 the average family income was about $ 39 , 000 , and in 2010 it was about $ 70 , 768 . Let x = 0 represent 1990, x = 1 represent 1991, and so on. Find values for a and b so that f ( x ) = a x + b models the data A= _____. B=______. What was the average family income in 2005?
Answer:
[tex]f(x) = 1588.4x + 39000[/tex]
[tex]f(15) = 62826[/tex]
Step-by-step explanation:
Given
In 1990; Income= $39000
In 2010; Income= $70768
Solving (a): An equation in form of f(x) = ax + b
First, we need to determine the slope, a
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Taking y as income and x as year index.
When x = 0; y = 39000
When x = 20; y = 70768
Substitute these values in the above formula
[tex]a = \frac{70768 - 39000}{20 - 0}[/tex]
[tex]a = \frac{31768}{20}[/tex]
[tex]a = 1588.4[/tex]
Next, is to determine the formula using:
[tex]y - y_1 = a(x - x_1)[/tex]
Considering :When x = 0; y = 39000, we have
[tex]y - 39000 = 1588.4(x - 0)[/tex]
[tex]y - 39000 = 1588.4x[/tex]
Make y the subject of formula
[tex]y = 1588.4x + 39000[/tex]
Express y as a function of x
[tex]f(x) = 1588.4x + 39000[/tex]
Solving (b): Income in 2005
In 2005, x = 15
So:
[tex]f(x) = 1588.4x + 39000[/tex] becomes
[tex]f(15) = 1588.4 * 15 + 39000[/tex]
[tex]f(15) = 62826[/tex]
