Hey there! :)

Answer:

a. b = y - mx

b. x = y - b /m

c. t = I/ pr

d. t = A - p/pr

Step-by-step explanation:

a. y = mx + b (for b)

Isolate the b variable by subtracting both sides by mx:

y - mx = b.

Therefore:

b = y - mx.

b. y = mx + b (for x)

Subtract 'b' from both sides:

y - b = mx

Divide 'm' from both sides:

y - b / m = x

c. I = prt

Divide both sides by pr:

I /pr = t.

d. A = p + prt

Subtract p from both sides:

A - p = prt

Divide both sides by pr:

A - p / pr = t

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

devlian [24]

The constant of the proportional relationship graphed in this problem is of 10.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

In this problem, the points on the graph are: (0,0), (2,20), (4,40), ..., hence the constant is:

k = 40/4 = 20/2 = 10.

A 100-foot rope from the top of a tree house to the ground forms a 45∘ angle of elevation from the ground. How high is the top o

DochEvi [55]

Answer:

The height of tree house is 70.71 feet

Step-by-step explanation:

We are given that A 100-foot rope from the top of a tree house to the ground forms a 45∘ angle of elevation from the ground

Refer the attached figure

Length of rope AC = Hypotenuse =100 feet

The top of a tree house to the ground forms a 45∘ angle of elevation from the ground = $\angle ACB = 45^{\circ}$

We are supposed to find the height of tree house i.e.AB = Perpendicular

So, Using trigonometric ratio

$Sin \theta = \frac{perpendicular}{Hypotenuse}\\Sin 45= \frac{AB}{AC}\\\frac{1}{\sqrt{2}}=\frac{AB}{100}\\100 \times \frac{1}{\sqrt{2}}=AB\\70.71=AB$

Hence The height of tree house is 70.71 feet

Anyone know #3 for me I’m stuck

<h3>Answers: 4, 3, 2</h3>

Each number gets its own box, and the values are entered in that exact order.

============================================================

Explanation:

x and y are placeholders for numbers.

If we replace x with -1, then we get

y = -x+3

y = -(x)+3

y = -(-1)+3 ... replace x with -1

y = 1+3

y = 4

This means that x = -1 leads to y = 4. So we'll write 4 underneath the "-1" in the y row.

------------------------

Similarly, if x = 0, then

y = -x+3

y = -0+3

y = 0+3

y = 3

Leading to 3 being the next item we input.

------------------------

Finally, if x = 1, we get this y value

y = -x+3

y = -1+3

y = 2

Which is the last value in the bottom row.

------------------------

The order of the y values in the bottom row is therefore: 4, 3, 2

This means the points (-1, 4), (0, 3), and (1, 2) are on the line y = -x+3.

Side note: The equation y = -x+3 has slope -1 and y intercept 3.

= 4 (6) - 4 (√2) + √2 (6) - √2 <span>√2
</span>= 24 - 4√2 + 6√2 - 2
= (24 - 2) + (- 4√2 + 6√2)
= 22 + √2(- 4 + 6)
= 22 + √2 (2)
= 22 + 2√2
