Answer:
x = 63.5 degrees
Step-by-step explanation:
use sine:
sine = [tex]\frac{opposite}{hypotenuse}[/tex]
sine x = [tex]\frac{17}{19}[/tex]
sine x = 0.8947
sine-1 of 0.8947 = 63.4699
x = 63.4699

Find all real solutions and show work:
2x^3-3x^2+18x-27=0
Given:
The given equation is
[tex]2x^3-3x^2+18x-27=0[/tex]
To find:
All the real solutions.
Solution:
We have,
[tex]2x^3-3x^2+18x-27=0[/tex]
It can be written as
[tex]x^2(2x-3)+9(2x-3)=0[/tex]
[tex](2x-3)(x^2+9)=0[/tex]
Using zero product property, we get
[tex](2x-3)=0[/tex] and [tex](x^2+9)=0[/tex]
[tex]2x=3[/tex] and [tex]x^2=-9[/tex]
[tex]x=\dfrac{3}{2}[/tex] and [tex]x=\pm\sqrt{-9}[/tex]
We know that [tex]x=\pm\sqrt{-9}[/tex] is an imaginary number because there is a negative sign under the square root.
Therefore, [tex]x=\dfrac{3}{2}[/tex] is the only real solution of the given equation.

Collins has a part-time job as a dog walker. The table below shows the amount of money Collins earned for different numbers of hours of work:
Collins' Earnings from Dog Walking

66
Part A: What are the missing numbers in the table? Show your work. (4 points)
Part B: Collins also does part-time yard work. The ratio of the number of hours Collins works to the money he earns in dollars is 1:7. Create a table to show the money earned by Collins for 5, 6, and 8 hours of doing yard work. (3 points)
Part C: How many more dollars does Collins earn doing yard work for 5 hours than working as a dog walker for 5 hours? Show your work. (3 points)
Answer:
See below.
Step-by-step explanation:
Part A:
For Dog walking, he earns $30 for 5 hours of work.
He earns $36 for 6 hours of work.
$30/5 hours = $6/hour
$36/6 hours = $6/hour
He earns $6/hour dog walking.
For 8 hours, he earns 8 hours * $6/hour = $48
To earn $66, he works 66/6 = 11 hours.
5 30
6 36
8 48
11 66
Part B:
He earns $7/hour for yard work, so multiply the number of hours by 7 to find the money he earns.
Table for yard work
Hours Money
5 $35
6 $42
8 $56
Part C:
For 5 hours, he earns $35 for yard work and $30 as a dog walker.
$35 - $30 = $5

The area of the triangle is 108.7 square yards.
What is the area of the triangle?Let a, b, and c is the sides of the triangle.
The area of the triangle is given as
S = (a + b + c) / 2
[tex]\rm A = \sqrt{s(s - a)(s - b)(s -c )}[/tex]
The third side of the triangle will be
c² = a² + b² - 2ab cos θ
c² = 9.5² + 23² - 2 × 9.5 × 23 × cos 85°
c² = 619.25 - 38.09
c² = 581.16
c = 24.11 yd
Then the area of the triangle will be
S = (9.5 + 23 + 24.11) / 2
S = 56.61 / 2
S = 28.3
Then the area will be
[tex]\rm A = \sqrt{28.3(28.3 - 24.11)(28.3 - 23)(28.3 - 9.5)}[/tex]
Simplify the expression, then the value will be
A = √11815.01
A = 108.7 square yd
The area of the triangle is 108.7 square yards.

i just did this one lol
The system of equations that describes the problem situation is y=250+0.12x and y=475+0.08x. The correct option is D.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that The first store will pay her a weekly salary of $250 plus a commission of 12% of her sales. Therefore, the equation can be written as,
Total earning = Weekly salary + 12% of weekly sales
y = 250 + 0.12x
Also, The second store will pay her a weekly salary of $475 plus an 8% commission. Therefore, the equation can be written as,
Total earning = Weekly salary + 8% of weekly sales
y = 475 + 0.08x
Hence, the system of equations that describes the problem situation is y=250+0.12x and y=475+0.08x.

Suppose you dilate a square with a length and width of 12 by a scale factor of 1. What is
the width of the new image?
Answer:
12Step-by-step explanation:
Given the length and width of a square to be 12
If the of the square is dilated by a factor of 1, this means that the value will be multiplied by 1 as shown;
New width = Old width * 1
New Width = 12 * 1
New width = 12
Hence the width of the new image will also be 12
