Don’t mind the work in the box I didnt have space on the other question.
Answer:
9.3 units
Step-by-step explanation:
By Pythagoras Theorem:
[tex] {x}^{2} + {(18 - 5)}^{2} = {16}^{2} \\ \\ {x}^{2} + {13}^{2} = {16}^{2} \\ \\ {x}^{2} + 169 = 256 \\ \\ {x}^{2} = 256 - 169 \\ \\ {x}^{2} = 87 \\ \\ x = \sqrt{87} \\ \\ x = 9.32737905 \\ \\ x \approx9.3[/tex]

ii. Are the vectors = <2, 3> and = <-3, -2> parallel? Show your work and explain.
Type your response here:
Answer:
Hey there,
The answer is below!!
Step-by-step explanation:
Knowing that those vectors start at the point (0,0) we can "think" them as lines.
As you may know, two lines are parallel if the slope is the same, then we can find the "slope" of the vectors and see if it is the same.
A) the vectors are: (√3, 1) and (-√3, -1)
You may remember that the way to find the slope of a line that passes through the points (x1, y1) and (x2, y2) is s = (y2 - y1)/(x2 - x1)
Because we know that our vectors also pass through the point (0,0)
then the slopes are:
(√3, 1) -----> s = (1/√3)
(-√3, -1)----> s = (-1/-√3) = (1/√3)
The slope is the same, so the vectors are parallel.
Part B:
The vectors are: (2, 3) and (-3, -2)
the slopes are:
(2, 3) -----> s = 3/2
(-3, -2)----> s = -2/-3 = 2/3
the slopes are different, so the vectors are not parallel.

Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes ne sells in a day. His daily
earnings goal is $112.
Write an equation to determine how many pairs of shoes, D, Roger must sell in a day to meet his daily earnings
goal
Answer:
Equation : y = 4.50D + 40
Number of pairs = 16
Step-by-step explanation:
It is given that:
Per day wage of Roger = $40
Commission on per pair of shoes = $4.50
Daily goal = $112
Number of pairs of shoes = D
Total earning = y
y = 4.50D + 40
112 = 4.50D + 40
4.50D = 112 - 40
4.50D = 72
Dividing both sides by 4.50
[tex]\frac{4.50D}{4.50}=\frac{72}{4.50}\\D = 16 \\[/tex]
Therefore,
Equation : y = 4.50D + 40
Number of pairs = 16
One airplane located 200km north and 50km east of an airport. A second plane at the same altitude is located 30km north and 100km west. The distance between the planes is closet to:
Answer: 200
Step-by-step explanation: You can use the Pythagorean theorem for this question. First, you must find a and b. You can do this by finding the distance between North and South, and East and West. For this specific equation, you'd use 200 North - 30 North to get 170 miles on the y-axis. Then, you'd do 50 East + 100 West to get 150 kilometers distance on the x-axis. Now that you have 170 and 150, you can begin the equation
170^2 + 150^2 = c^2
28900 + 22500 = c^2
51400 = c^2
√51400 = √c^2
~226 = c
They are approximately 226 kilometers apart, and 226 is closest to 200, which is B.

What is the value of x?
Enter your answer in the box.
Answer:
x = 111º
Step-by-step explanation:
In a heptagon, (A polygon with 7 sides, and therefore 7 angles), the sum of the interior angles is always 900º (just like the sum of all interior angle in a quadrilateral is always 360º). So you can add up all of the interior angles, and subtract them from 900º.
900º - (158º + 120º + 126º + 125º + 121º + 139º) = 111º
The price of a notebook has risen to $3.70 today. Yesterday's price was $3.20 . Find the percentage increase. Round your answer to the nearest tenth of a percent.

help please! answer correctly for brainliest . ( look at picture for problem )
Answer:
The slope is -2.
Step-by-step explanation:
1) The equation for a slope is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
2) Plug in x and y values into the equation. I plugged in (3,0) and (8,-10) into the equation.
3) You end up with: [tex]\frac{-10 -0}{8-3}[/tex], which simplifies down to [tex]\frac{-10}{5}[/tex], which equals -2.
Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck on your assignment. :)

Answer:
3.712 x 10^8
Step-by-step explanation:
use the commutative property to reorder the terms
(5.8x 6.4) x (10^5 x 10^2)
multiply 5.8 x 6.4 = 37.12
add 5+2=8
37.12 x 10^7
write the number in scientific notation
3.712 x 10^8
that'sur answer
Answer: 5.8 x 10^5 =
6.4 x 10^2 =
Step-by-step explanation:
There is 5 10's because number of exponents are 5
so you multiply 5.8 by 10 10 10 10 10
The other is 6.4
multiply that by 10 10
But you can't multiply by all of that with one constant
So you answer the first one 10 x 10 x 10 x 10 x 10 = 100000
the other is 100
So now you multiply 5.8 by 100000
And multiply 6.4 by 100
