Answer:
after taxes: $38,250monthly: $3,187.50Step-by-step explanation:
Your after-tax income is the gross pay less the amount that is paid to taxes. The monthly income is 1/12 of the annual amount.
__
The tax is the taxed amount multiplied by the tax rate.
taxes = $45,000 × 15% = $6,750
The after-tax income is the income less the taxes:
after-tax income = $45,000 -6,750 = $38,250
The monthly income is 1/12 of this amount:
monthly income = annual income/12 = $38,250/12 = $3,187.50

Is the shaded triangle a right triangle?
no
The sides of the shaded triangle do not form a Pythagorean triple, therefore, it is not a right triangle.
What is a Right Triangle?A triangle is a right triangle if the square of its longest side equals the sum of the square of the other two smaller sides, based on the Pythagorean Theorem.
Using the Pythagorean Theorem, find the lengths of the legs of the shaded triangle, and find out the sum of their squares equals the length of the longest side.
First leg of the shaded triangle = √(8² + 6²) = 10
Second leg of the shaded triangle = √(8² + 9²) = 12
The third side (longest side) of the shaded triangle is 9 + 6 = 15.
15² = 10² + 12²
225 = 244 (not true)
Therefore, the shaded triangle is not a right triangle.

Lines c and d are perpendicular. The slope of line c is −1/3. What is the slope of line d?
Answer:
1/3
Step-by-step explanation:
When two lines are perpendicular, it means the lines intersect at a right angle and have opposite reciprocal slopes.The slope of perpendicular lines are the negative reciprocals of each other, and a pair of these lines intersects at 90 degrees.
To figure out d we need to use the formula:
- 1 / m

5. Sarah made 17 out of 25 free throws during practice. What percentage of free throws did she NOT make? A. 68% B. 58% C. 32% D. 36%
Answer:
C. 32%
Step-by-step explanation:
The percent 17 is of 25.
17 of 25 can be written as:
17/25
To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100
17/25 * 100/100
= (17 * 100/25) * 1/100 = 68/100
Therefore, the answer is 68%
If Sara made 68% of her free shows, that means she didn't make 32% of her free throws (100 - 68 = 32).

Where is the function f(x)=3x^2-6x-45/x^2-5x discontinuous, and what types of discontinuities does it have?
Answer:
Below.
Step-by-step explanation:
f(x)=3x^2-6x-45/x^2-5x
= 3x^2-6x-45 / (x(x - 5))
The denominator is zero when x - 0 and x = 5.
So there will be a vertical asymptote at x = 0 and a hole at x = 5.
If we do the division we get f(x) = 3 remainder 9x - 45
so there will also be a horizontal asymptote where x = 3.
Answer:
Hole at (3, 4.8)
Asymptotes at x = 0 and y = 3
Step-by-step explanation:
[tex]f(x)=\dfrac{3x^2-6x-45}{x^2-5x}[/tex]
Factor the numerator:
[tex]\implies 3x^2-6x-45[/tex]
[tex]\implies 3(x^2-2x-15)[/tex]
[tex]\implies 3(x^2+3x-5x-15)[/tex]
[tex]\implies 3(x(x+3)-5(x+3))[/tex]
[tex]\implies 3(x-5)(x+3)[/tex]
Factor the denominator:
[tex]\implies x^2-5x[/tex]
[tex]\implies x(x-5)[/tex]
Factored form of function:
[tex]\implies f(x)=\dfrac{3(x-5)(x+3)}{x(x-5)}[/tex]
Discontinuity: a point at which the function is not continuous.
Holes
After factoring the rational function, if there is a common factor in both the numerator and denominator, there will be a hole at that point (x-value):
[tex]\implies (x-5)=0 \implies x=5[/tex]
Factor out the common factor from the function and input the found value of x into the new function to find the y-value of the hole:
[tex]\implies f(x)=\dfrac{3(x+3)}{x}[/tex]
[tex]\implies f(5)=\dfrac{3(5+3)}{5}=4.8[/tex]
Therefore, there is a hole at (5, 4.8)
Asymptotes
To find the vertical asymptotes, set the denominator of the new (factored) function to zero and solve:
⇒ Vertical Asymptote at x = 0
As the degrees of the leading terms of the numerator and denominator are equal (both x²), the horizontal asymptote is equal to the ratio of the leading coefficients.
⇒ Horizontal Asymptote at y = 3

money in the account after
10 years if it earns 1.15%
interest compounded semi-
annually.
Answer:
$1.51 is in the account after 10 years.
Step-by-step explanation:
Step 1: Identify the Type of Problem
We can see that this is a compound interest problem due to the phrase "earns 1.15% interested compounded" in the problem.
The formula for compound interest is as follows:
[tex]A=P(1+\frac{r}{n})^{n*t}[/tex] where:
A = final amount P = principal amount (in other words, the initial or first investment)r = interest rate (as a decimal)n = number of times interest is compounded per yeart = time (in years)Step 2: Identify what we Know
Now that we have the formula we'll be working with, let's see what we know. From the problem, we can see:
A = ? (this is what we are solving for)P = $1.35r = 1.15% → 0.0115n = 2 (semi-annually means twice a year)t = 10 yearsStep 3: "Plug and Chug"
Now, all we have to do is substitute the above values into our formula. Doing so, we get:
[tex]A=1.35*(1+\frac{0.0115}{2})^{2*10} \\= \bf \$1.51[/tex]
(Note: Since the answer is an amount of money, I have rounded to the hundreths place.)
