Answer:
Part A: If Beatrice inputs −8 into the function, she must get an output of 8.
Part B: (−4,8) , (4,−8) , (8,−4)
Step-by-step explanation:
Part A:
We know that a function is a relation that maps elements from one set (The domain, the set of the inputs) into elements from another set (the range, the set of the outputs)
Such that each input can be mapped into only one output.
Then if we know that our function maps the input -8 into the output 8.
Always that we use this function with the input -8. we will have the same output, 8.
Then we can conclude that the correct option to the first part is:
"If Beatrice inputs −8 into the function, she must get an output of 8. "
Part B:
Remember, -8 is mapped into 8, then the point (−8,4) (this says "-8 is mapped into 4) can never be on the graph of the function.
But the points:
(−4,8) , (4,−8) , (8,−4)
Could be on the graph of the function.
Answer:
correct A:-8,8
B: -4,8

What events in Hitler Youth have impacted individuals or ideas?
Answer:
Hitler Youth, founded in 1926, young children were taught how to use weapons and how to kill. This could have had a psychological effect on their developing minds.

9514 1404 393
Answer:
a) $215,892.50
c) $220,803.97
e) $222,534.58
f) $222.554.09
Step-by-step explanation:
The compound interest formula is ...
FV = P(1 +r/n)^(nt)
where principal P is invested at annual rate r for t years, compounded n times per year. In this problem, you have P=100,000, r=0.08, t=10, and the only variable of interest is n.
When calculations are repeated, it is often convenient to let a calculator or spreadsheet do them. You only need to program the formula once, then use it for the different values of the variable of interest. Most spreadsheets have this formula built in, so you don't even need to program it.
__
For continuous compounding, the formula is ...
FV = Pe^(rt)
FV = 100,000e^(0.08·10) = 222,554.09

We need to know total number of miles and
we need to know the distance (in miles) between san diego to albuquerque, albuquerque to omaha, omaha to chicago (it’s labeled springfield on the map below but it’s chicago), then chicago (which is again labeled as springfield on the map below) to nashville
The scale is 1 cm to 204
THE INFORMATION, MAP, INSTRUCTIONS, SCALE, AND QUESTIONS ARE BELOW!
Answer:
total mile=(3.75+4.25+2.25+2)×204mile=12.25×204=2499mile
9514 1404 393
Answer:
765 mi867 mi459 mi408 mitotal: 2499 miStep-by-step explanation:
The estimated mileage is found by multiplying the map scale by the map distance:
#1: (204 mi/cm)(3.75 cm) = 765 mi
The last of your attachments correctly shows the mileage for each of the distances you have identified on the map.
(Please note that the map is actually showing Springfield, IL. The location of Chicago is at the south end of Lake Michigan, not in the middle of IL. Perhaps the grid incorrectly lists Chicago instead of Springfield.)
__
Of course, the total distance is the sum of the distances of the legs of the trip:
765 +867 +459 +408 = 2499 . . . . miles total distance

6. If A= 4, and B = 5, what is length of the hypotenuse? Show all work
Answer:
The formula is a^2 + b^2 = c^2
Step-by-step explanation:
A and B are legs and C is the hypothunisis.
The theorem is used for triangles.
4^2 + 5^2 = c^2
16 + 25 = c^2
41 = c^2
sqr(41) = sqr(c)^2

Find the value of x that makes the quadrilateral a parallelogram
What is x?
To make it a parallelogram, the diagonals have to bisect each other (6x=3x+2)
Calculate and you will get x = 2/3
The value of x that makes the quadrilateral a parallelogram is 2/3.
What is a parallelogram?A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.
We have a quadrilateral.
To show that the quadrilateral is a parallelogram:
If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.
That means,
6x = 3x + 2
3x = 2
x = 2/3
Therefore, the value of x is 2/3.

Examine the linear graph to find the slope , y-intercept, and write the equation for this linear relationship
Answer:
The slope of the line is: [tex]m=-\frac{1}{2}[/tex]
The y-intercept b = 3
The slope-intercept equation of the line is: [tex]y\:=\:-\frac{1}{3}x+3[/tex]
Step-by-step explanation:
Taking two points from the given graph
(0, 3) and (6, 0)
Determining the slope m
The slope between (0, 3) and (6, 0) using the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between (x₁, y₁) and (x₂, y₂)
In our case,
(x₁, y₁) = (0, 3) (x₂, y₂) = (6, 0)now substitute (x₁, y₁) = (0, 3) and (x₂, y₂) = (6, 0) in the slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{0-3}{6-0}[/tex]
[tex]m=-\frac{3}{6}[/tex]
[tex]m=-\frac{1}{2}[/tex]
Thus, the slope of the line is: [tex]m=-\frac{1}{2}[/tex]
Determining the y-intercept (b)
The slope-intercept form of the line equation is given by
[tex]y = mx+b[/tex]
where
[tex]m[/tex] is the slope[tex]b[/tex] is the y-interceptFrom the graph, we can figure out the y-intercept by checking the value of y at x = 0.
If we closely check the graph, at x = 0, the value of y = 3
Therefore, the y-intercept b = 3
Slope-intercept Equation
We already know that the slope-intercept form of the line equation is
[tex]y = mx+b[/tex]
substituting b = 3 and m = -1/2
[tex]y\:=\:-\frac{1}{2}x+3[/tex]
Therefore, the slope-intercept equation of the line is: [tex]y\:=\:-\frac{1}{2}x+3[/tex]

Alexander builds a triangular frame with side lengths of 3 ft and 5 ft and a 120∘ angle between them. Which can be the length of the unknown side of the frame?
Answer:
i got 7ft for the answer
Step-by-step explanation:
The length of the unknown side of the triangular frame is 7 ft.
What is a triangle?"A simple closed curve or a polygon formed by three line-segments (sides) is called a triangle."
From the drawn triangle
According to the law of cosines
[tex]x^{2} =3^{2} +5^{2} +2[/tex] × [tex]3[/tex] × [tex]5[/tex] × [tex]cos 120^{0}[/tex]
⇒ [tex]x^{2} =9+25+2[/tex] × [tex]3[/tex] × [tex]5[/tex] × [tex]\frac{1}{2}[/tex]
⇒ [tex]x^{2} = 9+25+15[/tex]
⇒ [tex]x^{2} = 49[/tex]
⇒ [tex]x = \sqrt{49}[/tex]
⇒ [tex]x = 7[/tex]
Hence, the length of the unknown side of the triangular frame is 7 ft.
