so given $750 as gross pay
18% withheld for taxes
48 withheld for personal term this also means 4%
18% = 0.18
4% = 0.04
so to get the annual net,
750 x (1 - 0.18 - 0.04) x 24
= 14040
=$14, 040

In the right triangle ABC angles B and C are congruent. What is the measure of B and C?
SOLUTION:
Step 1:
In this question, we are given the following:
Step 2:
From Triangle ABC, we have that:
[tex]\begin{gathered} A=90^0(Right\text{ angle)} \\ B\text{ = x} \\ C\text{ = x} \\ \text{Because Angles B and C are congruent} \end{gathered}[/tex][tex]\begin{gathered} 90^0+x+x=180^0 \\ 90^{0\text{ }}+2x=180^0 \\ \text{collecting like terms, we have that:} \\ 2x=180^0-90^0 \\ 2x=90^0 \\ \text{Divide both sides by 2, we have that:} \\ \text{x = }\frac{90^0}{2} \\ \text{x = 45}^0 \end{gathered}[/tex]CONCLUSION:
The measure of B and C are: 45 and 45 degrees --- OPTION A
If f(x) = 3tan2x, find f'(pi/2)
Given the function f(x) defined as:
[tex]f(x)=3\tan(2x)[/tex]We need to find the derivative first. Using the chain rule, we know that:
[tex](\tan u)^{\prime}=u^{\prime}\cdot\sec²u[/tex]Then, taking the derivative if u = 2x:
[tex]\begin{gathered} f^{\prime}(x)=3(2)\sec²(2x) \\ \\ \Rightarrow f^{\prime}(x)=6\sec²(2x) \end{gathered}[/tex]Using this result, we can evaluate the derivative at x = π/2:
[tex]\begin{gathered} f^{\prime}(\frac{\pi}{2})=6\sec²(2\cdot\frac{\pi}{2})=6\sec²(\pi)=6\cdot(-1)² \\ \\ \therefore f^{\prime}(\frac{\pi}{2})=6 \end{gathered}[/tex]In a recent survey of 1,050 people, 42 said that their favorite color of car was red. What percent of the people surveyed liked red cars?
In order to calculate the percentage of surveyed people that liked red cars, we need to divide this amount of people by the total amount of people surveyed.
So we have:
[tex]p=\frac{42}{1050}=0.04=4\text{\%}[/tex]Therefore the percent of the people surveyed that liked red cars is 4%.
Simplify the absolute value -17
Answer
The answer is 17.
Explanation
The absolute value of any number is taking the positive part of any number. For example, the absolute value of -2 = | -2 | = 2, the absolute value of -99 = | -99 | = 99.
So, the absolute value of -17 = | -17 | = 17.

Use the figure below to complete the following problem.Given:FLAG isGXYZ isGхYZY=
∠Y = ∠L (option C)
Explanation:FLAG is similar to XYZG.
This means the corresponding angles are congruent (equal).
∠F = ∠X
∠L = ∠Y
∠A = ∠Z
∠G =∠G
Hence, ∠Y = ∠L (option C)
what are the following transformations: f(-x)-4a. reflection over the y-axis and 4 units down b. reflection over the x axis and 4 units down c. reflection over the x axis and 4 units right d. reflection over the y-axis and 4 units right
a. reflection over the y-axis and 4 units down
Explanations:Note:
If f(x) is reflected over the x-axis, it becomes -f(x) because the y coordinate is negated.
If f(x) is reflected over the y-axis, it becomes f(-x) because the x coordinate is negated.
Therefore, for f(-x)-4, f(x) is reflected over the y-axis, and then translated 4 units down

If a line passes through (-4,3) and (6,2) what's the equation if an equation isn't possible say no
First, let's find the slope of the line that passes through the points (-4,3) and (6,2):
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \Rightarrow m=\frac{2-3}{6-(-4)}=\frac{-1}{6+4}=-\frac{1}{10} \end{gathered}[/tex]Now we can use the first point to get the equation of the line:
[tex]\begin{gathered} (x_1,y_1)=(-4,3) \\ y-y_1=m(x-x_1) \\ \Rightarrow y-3=-\frac{1}{10}(x-(-4))=-\frac{1}{10}(x+4)=-\frac{1}{10}x-\frac{4}{10}=-\frac{1}{10}x-\frac{2}{5} \\ \Rightarrow y=-\frac{1}{10}x-\frac{2}{5}+3=-\frac{1}{10}x-\frac{2}{5}+\frac{15}{5}=-\frac{1}{10}x+\frac{13}{5} \\ y=-\frac{1}{10}x+\frac{13}{5} \end{gathered}[/tex]therefore, the equation of the line is y=-1/10x+13/5

what is the solution set of y equals x squared plus 2X + 7 + y equals x + 7
The given equations are
y = x^2 + 2x + 7
y = x + 7
We would substitute y = x + 7 into the first equation. It becomes
x + 7 = x^2 + 2x + 7
Collecting like terms, it becomes
x^2 + 2x - x + 7 - 7 = 0
x^2 + x = 0
By factorising x, it becomes
x(x + 1) = 0
Thus,
x = 0 or x + 1 = 0
x = 0 or x = - 1
Substituting x = 0 into y = x + 7, it becomes
y = 0 + 7
y = 7
Thus, one solution set is (0, 7)
Substituting x = - 1 into y = x + 7, it becomes
y = - 1 + 7
y = 6
Thus, another solution set is (- 1, 6)
Therefore, the solution sets are
{(0, 7), (- 1, 6)}

Info given
Bob and dale served a total of 83 orders Monday at the school cafeteria. rita served 9 fewer orders than bob. Dale served 2 times as many orders as bob. how many orders did they each serve
Solution
We can find the number of orders for Rita like this:
[tex]\text{Rita}=83-9=74[/tex]And for Dale we have this:
[tex]\text{Dale}=2\cdot83=166[/tex]solve following equation6+y=18
y=12
Explanation
The subtraction property of equality tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same,
in order to know the y value, we have to isolate y, then
Step 1
subtract 6 in both sides
[tex]\begin{gathered} 6+y=18 \\ 6+y-6=18-6 \\ \end{gathered}[/tex]Step 2
add like terms
[tex]\begin{gathered} 6+y-6=18-6 \\ y=12 \end{gathered}[/tex]therefore, the answer is

A scientist was in a submarine below sea level, studying ocean life. Over the next ten minutes, she descended 21.4 feet. How many feet had she been below sea level, if she was 90.6 feet below sea level after she descended?
Step 1:
Let the height below sea level before she descends = h feet
The length she descended after 10 minutes = 21.4 feet
The height of the submarine after descended below the sea level = 90.6 feet
Step 2:
Height of the submarine before descended below the sea level
x = 90.6 - 21.4
x = 69.2 feet
Final answer
69.2 feet
If a rotation angle is 540 degrees how is it possible that the location is Quadrant 1 with a reference angle of 0?
Since a whole revolution has 360º, when we have an angle bigger than 360º the angles start to repeat.
We can subtract 360º to the given angle to find the coterminal angle. In this case:
[tex]540º-360º=180º[/tex]And from an reference angle of 0º, this is exactly a half revolution. Thus, the angle is in the x axis, and it's coterminal angle is 180º

time t = 7 sec
tangential speed = 2[tex]\pi[/tex]r/t

= 94.23
What is tangential speed?Tangential speed is the linear component of its velocity as it moves in a circle. If an object moves along a circular path at a distance r from the centre of the circle, the velocity of the object is tangent to the circle at some point.
In mathematics, a tangent is a line that touches a curve at one point. A quantity is tangent to another if it touches the other quantity once and then moves in the other direction.
Therefore, the tangential speed is a measure of the speed at any point where the tangent curves in this circular motion. Tangential velocity is useful for circular motion because it allows angular motion to be transformed into linear motion.

Given systemy = x² + 9 x + y = 11Substitute the value of y into second equationx + x² + 9 = 11x² + x - 2 = 0x² +2x - x - 2 = 0x(x + 2) - (x + 2) = 0(x + 2)(x - 1) = 0x + 2 = 0 and x - 1 = 0x = - 2 and x = 1 Find the value of yx = -2 ⇒ y = 11 - (-2) = 13x = 1 ⇒ y = 11 - 1 = 10Answer:
[tex](x,y)=\left(\; \boxed{-2,13} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]
[tex](x,y)=\left(\; \boxed{1,10} \; \right)\quad \textsf{(larger $x$-value)}[/tex]
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}\phantom{bbbb}y=x^2+9\\x+y=11\end{cases}[/tex]
To solve by the method of substitution, rearrange the second equation to make y the subject:
[tex]\implies y=11-x[/tex]
Substitute the found expression for y into the first equation and rearrange so that the equation equals zero:
[tex]\begin{aligned}y=11-x \implies 11-x&=x^2+9\\x^2+9&=11-x\\x^2+9+x&=11\\x^2+x-2&=0\end{aligned}[/tex]
Factor the quadratic:
[tex]\begin{aligned}x^2+x-2&=0\\x^2+2x-x-2&=0\\x(x+2)-1(x+2)&=0\\(x-1)(x+2)&=0\end{aligned}[/tex]
Apply the zero-product property and solve for x:
[tex]\implies x-1=0 \implies x=1[/tex]
[tex]\implies x+2=0 \implies x=-2[/tex]
Substitute the found values of x into the second equation and solve for y:
[tex]\begin{aligned}x=1 \implies 1+y&=11\\y&=11-1\\y&=10\end{aligned}[/tex]
[tex]\begin{aligned}x=-2 \implies -2+y&=11\\y&=11+2\\y&=13\end{aligned}[/tex]
Therefore, the solutions are:
[tex](x,y)=\left(\; \boxed{-2,13} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]
[tex](x,y)=\left(\; \boxed{1,10} \; \right)\quad \textsf{(larger $x$-value)}[/tex]
