We're going to draw a triangle on the graph paper to solve this. (in theory)
The top point is at 2 on the x axis, and the bottom is at 6. That's a difference of 4. Draw a line from the top dot over 4 spaces, so a line dropped from there could go straight to the bottom dot. We'll call this line/side of the triangle a, and a = 4.
Then we drop the line from there (6, 4) down to the second dot at (6, -5). That line is 9 places long. We'll call this line/side of the triangle b, and b = 9.
(This is so much easier to draw than type, I'll attach a picture).
Then we connect the two dots diagonally to form line/side c of our triangle. This is the length we don't know.
The pythagorean theorem says a^2 + b^2 = c^2
So a = 4, b = 9, c is unknown for our triangle
(4)(4) + (9)(9) = c^2
16 + 81 = 97
The square root of 97 = 9.8488, so if they have you round, I would say 9.85

The perimeter of a square P depends on the length of its sides S this can be written in function notation as P( s) what is the best interpretation of p(3)=12
Answer:
Step-by-step explanation:
The best interpretation of P(3) = 12 is that if the length of the sides of the square is 3 units, then the perimeter of the square is 12 units.
What is a square?A square is a two-dimensional figure that has four sides and all four sides are equal.
The area of a square is side²
We have,
The best interpretation of P(3) = 12 is that if the length of the sides of the square is 3 units, then the perimeter of the square is 12 units.
i.e
Since the function P is defined as the perimeter of the square in terms of its side length S,
We can substitute S = 3 into the function and get P(3) = 12.
This means that the sum of the four sides of the square when its length is 3 units is equal to 12 units.
Thus,
The best interpretation of P(3) = 12 is that if the length of the sides of the square is 3 units, then the perimeter of the square is 12 units.

3) Raeana is twice as old as Madeline, and Laura is 10 years older than Raeana.
If Laura is 50 years old, how old is Madeline? Let m represent Madeline's age in
years, and let r represent Raeana's age in years.
Answer:
M = 20; R = 40
Step-by-step explanation:
R = 2M
L = R + 10
L = 50
50 = R + 10
(Take away 10 from both sides)
50 - 10 = 40
40 = R
Remember, R = 2M
40 = 2M
(Divide both sides by 2)
40 / 2 = 20
20 = M

6.) Convert the following linear equation into slope-intercept form.
4x + 3y = 9
Answer:
[tex]y=\frac{-4}{3} +9[/tex]
Step-by-step explanation:
Slope-intercept form is y-mx+b. To find slope-intercept form solve for y.
First, subtract 4x from both sides,
3y=-4x+9
Then, divide both sides by 3,
y=-4/3x+3

A)The price was increased by 40% and then decreased by 85%.
B) The price was increased by 40% and then decreased by 15%.
C)The price was increased by 40% and then decreased by 0.15%.
D) The price was increased by 140% and then decreased by 85%.
Answer:
D
Step-by-step explanation:
D) The price was increased by 140% and then decreased by 85%.
Answer:
B
Step-by-step explanation:
The price was only increased by 40% because for example, the starting price was 100, then if you increased it by 140% or $140, then the price would be 240.
next, the decreased by 15% and not 85% because 100% - 15% = 85%

When the peak temperature is 40°C, 48 units of electricity are used on average.
D.
When the peak temperature is 40°C, 120 units of electricity are used on average.
Answer:
B. When the peak temperature is 40°C, 72 units of electricity are used on average.Step-by-step explanation:
We see the relationship is closer to linear in the interval 30 to 40
Approximate points:
(30, 34) and (34, 54)The slope of the line:
m = (54 - 34)/(34- 30) = 20/4 = 5The line is:
y - 34 = 5(x - 30)y = 5x - 116At x = 40, the value of y would be:
y = 5*40 - 116 = 84The closet option is B

equilateral triangle with side lengths of 8 millimeters and a height of about 5.2
millimeters. What is the approximate surface area of the prism?

1410 mm²Step-by-step explanation:
Given triangle prism with:
a = 8mm, h = 5.2 mm, l = 57 mmTotal surface area:
S = Pl + ah = 3al + ah = a(3l + h)S = 8(3*57 + 5.2) = 1409.6 mm² ≈ 1410 mm²Micayla wants the print shop to reduce the size of her painting but keep the ratio of length to width so that it will fit her frame. Study the scale drawings to determine the proportional relationship between her painting and the frame she wants to use.
Answer:
The width of the frame must be 12 inches (15in by 12in)
Step-by-step explanation:
Given
See attachment for painting and frame
Required
Determine the dimension of the frame
To do this, we make use of the following scale ratio.
[tex]Scale = Length : Width[/tex]
For the painting,
[tex]Scale = 20: 16[/tex]
For the frame,
[tex]Scale = 15: w[/tex]
Since she wants to maintain the same ratio; both scale must be the same.
i.e.
[tex]15 : w = 20 : 16[/tex]
Express as fraction
[tex]\frac{w}{15} = \frac{16}{20}[/tex]
[tex]\frac{w}{15} = 0.8[/tex]
Make w the subject
[tex]w = 15 * 0.8[/tex]
[tex]w = 12[/tex]
The width of the frame must be 12 inches i.e. 15in by 12in frame

Answer:
f(x) = 2(4^x)
Step-by-step explanation:
Look at x = 0 in the table. It corresponds to f(x) = 2.
Now look at your answer:
f(x) = 4^x
Use x = 0:
f(0) = 4^0 = 1, but the table has f(0) = 2, so your answer is not correct.
Notice the numbers in the f(x) column. They are 2, 8, 32, 128.
Notice that they are 2 times perfect squares.
2 = 2 * 1
8 = 2 * 4
32 = 2 * 16
128 = 2 * 64
Try
f(x) = 2(4^x)
Now you have
f(0) = 2(4^0) = 2 * 1 = 2
f(1) = 2(4^1) = 2 * 4 = 8
f(2) = 2(4^2) = 2 * 16 = 32
f(3) = 2(4^3) = 2 * 64 = 128
and all the given points work.
Answer: f(x) = 2(4^x)
