Answer:

C. y = 3x - 4

Step-by-step explanation:

slope intercept form - y = mx + b

where m = slope and b = y intercept

our first step is to find the slope

remember slope = change in y over change in x

looking at the line, as y goes up 3 x goes up 1

hence, slope = 3/1 or just 3

so m = 3

now to find the y intercept ( or b )

b is equal to the y value of the coordinate where the line passes the y axis

the line passes the y axis at ( 0 , -4 ) and the y value of that coordinate is -4

hence b = -4

now we plug everything into the slope intercept form

we get the equation y = 3x - 4

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

Drag each tile to the correct box.

Anni [7]

Answer:

$3x^{2}y^{2}\sqrt[4]{7xy^{3}}$ .

Step-by-step explanation:

Since we have to find the simplified form of the expression as below

$\sqrt[4]{567x^{9}y^{11}}$

we will solve the expression as below

$=[567x^{9}y^{11}]^{\frac{1}{4}}$

$=(81\times 7)^{\frac{1}{4}}\times x^{\frac{9}{4}}\times y^{\frac{11}{4}}$

$=81^{\frac{1}{4}}.7^{\frac{1}{4}}.x^{\frac{8}{4}+\frac{1}{4}}.y^{\frac{8}{4}+\frac{3}{4}}$

$=(3^{4})^{\frac{1}{4}}.7^{\frac{1}{4}}.x^{2+\frac{1}{4}}.y^{2+\frac{3}{4}}$

$=3^{1}.7^{\frac{1}{4}}.x^{2}.x^{\frac{1}{4}}.y^{2}.y^{\frac{3}{4}}$

$=3.x^{2}.y^{2}.(7^{\frac{1}{4}}.x^{\frac{1}{4}}.y^{\frac{3}{4}})$

$=3x^{2}y^{2}.(7xy^{3})^{\frac{1}{4}}$

$=3x^{2}y^{2}\sqrt[4]{7xy^{3}}$ .

Wildfires in the United States covered three and forty-two hundredths million acres one year. The second year, they covered eigh

enyata [817]

Everything is in million acres, so we can just drop that while we work it out but just remember we have to add it back on at the end of the problem.

First year 3.42
Second year 8.71
Third year ???

Total 21.46

So...

3.42 + 8.71 + ? = 21.46
12.13 + ? = 21.46
? = 21.46 - 12.13
? = 9.33

The 3rd year 9.33 million acres were burned

*Note I put a ? for the unknown. I could have used x or y or anything else.
