Answer:

16

Step-by-step explanation:

(x - y)² = x² - 2xy + y²

x = x and y = a

2xy = 8x

2*x*a = 8x

     a = [tex]\frac{8x}{2x}[/tex]

a = 4

a²  = 16

Answer:

6 hours

Step-by-step explanation:

For Bob

12 hours = 1 fence

1 hour = 1/12 fence

Together Bob and Jen

4 hours = 1 fence

1 hour = 1/4 fence

Now, for Jen:

1 hour = 1/4 - 1/12= 3/12 - 1/12 = 2/12=1/6

Find the amount of time Jen will need:

1/6 fence = 1 hour

1 fence = 6 hour

Answer:

48 Ounces of red

Step-by-step explanation:

4+3=7

112/7= 16

you will need to add 3 ounces of red and 4 ounces of blue 16 times

16 x 3 (ounces of red)= 48

Answer:

90 degrees

Step-by-step explanation:

Answer:

x=103

Step-by-step explanation:

sum=(n-2)*180

sum=(6-2)*180

sum=4*180

sum=720

90+155+112+120+140+x=720

617+x=720

x=720-617

x=103

All you have to do is rotate the left-hand triangle to match the right one, and you see that the angle degrees match up, so KL = 9.5

Answer:

Each fraction is greater than the previous.

Step-by-step explanation:

Each fraction is equivalent to 2/3  and the next is 32/48 so the first choice is not true.

Answer:

Answer:

40 degrees

Step-by-step explanation:

- All internal angles of a triangle add up to 180 degrees.

- A right angle is 90 degrees.

90+50=140

subtract 140 from 180, which is 40 degrees.

Answer:

y - 20 = (-1/5)(x - 5)

Step-by-step explanation:

The slope of the given line is 5.  The slope of any line perpendicular to the given line is the negative reciprocal of the given slope:  

Slope of perpendicular line here is -1/5.

We use the point-slope formula as a framework here:

y - 20 = (-1/5)(x - 5)

Answer:

Positive

Step-by-step explanation:

Both of the roots are real numbers so that means the discrimnat is greater than zero or positive.

Answer:

f(4) = 6

Step-by-step explanation:

Given the rule f(n) = 4f (n - 1) + 2 where f(1) = 3, f(n) is just a fancy way to name the variable y. As you've seen before, there are equations that are usually y equals x and something. For example:

y = mx + b

is the same thing as

f(n) = y = mn + b.

It might be that you have multiple of the same equation where f(n) and f(x) have two different outcomes.

The f(n) part (bolded) is the "x variable" in this equation. So in f(1), n = 1.

f(n) = 4f (n - 1) + 2

f(n) = (4fn - 4f) + 2

f(n) = (n) + 2

f(1) = 1 +2

3 = 3

Now do the same thing for f(4):

f(n) = 4f (n - 1) + 2

f(n) = (4fn - 4f) + 2

f(n) = (n) + 2

f(4) = 4 + 2

f(4) = 6

Answer: The correct answer would be F. Half the students drank from 78 to 114 fluid ounces.

Step-by-step explanation:

The statement best describes the data represented in the box plot half the students drank from 78 to 114 fluid ounces. The correct option is F.

A rectangle is created to represent the second and third quartiles, normally with a vertical line inside to indicate the median value, in a simple way of presenting statistical data on a plot.

Given that students recorded the amount of liquid in fluid Ounces each of them drank In one day. The box plot shows the summary of the results. Amount of Liquid (fluid Ounces).

The highest and the lowest limit of the box plot is range from 78 to 114. The statement best describes the data represented in the box plot half the students drank from 78 to 114 fluid ounces.

Therefore, the correct option for the box plot will be F.

Answer:

The value of 6(2b-4) is 36.

Step-by-step explanation:

Given expression: 6(2b-4)

To find the value of 6(2b-4) at b=5, we need to substitute the b=5 in the expression, we get

6(2(5)-4)

= 6(10-4)

=6(6)

= 6x6=36

⇒ 6(2(5)-4)=36

Answer:

The value of 6(2b-4) when b=5 is 36.

Step-by-step explanation:

Given expression: 6(2b-4). To find the value of 6(2b-4) at b= 5, we need to substitute the b=5 in the expression, we get….Therefore, the value of 6(2b-4) is 36, when b=5.

Answer:

(-7, -2)

Step-by-step explanation:

Answer:

[tex](a)\ b = 8[/tex]

[tex](b)\ T = 3.1[/tex]

Step-by-step explanation:

Given

[tex]y = 2\sqrt x[/tex]

See attachment

Solving (a): Find b

At point b, [tex]x = 16[/tex]

So, the value of b is:

[tex]b = 2 * \sqrt{16[/tex]

[tex]b = 2 * 4[/tex]

[tex]b = 8[/tex]

Solving (b): Find T

First, we calculate the value of y at point T

[tex]y = 2\sqrt x[/tex]

At point T, [tex]x = 6[/tex]

So:

[tex]y = 2 * \sqrt 6[/tex]

[tex]y = 2 * 2.45[/tex]

[tex]y = 4.9[/tex]

To calculate T, we subtract the calculated height (y) from the value of b

[tex]T =b - y[/tex]

[tex]T = 8 - 4.9[/tex]

[tex]T = 3.1[/tex]
