Which of the following theorems verified that angle xyz is congruent too angle uwv?

Answer:

Option B.  AA

Step-by-step explanation:

we know that

Angle-Angle (AA) Similarity Postulate, states that If two angles of one triangle are congruent to two angles of another, then the triangles must be similar

In this problem

<em>In the triangle XYZ</em>

∠X=70°

∠Y=90°

∠Z=90°-70°=20° (remember that angle X and angle Z are complementary)

<em>In the triangle UWV</em>

∠V=20°

∠W=90°

∠U=90°-20°=70° (remember that angle V and angle U are complementary)

therefore

Traingles XYZ and UWV are similar by AA Similarity Postulate

Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level
jek_recluse [69]

Answer:

Step-by-step explanation:

Is this the entire question? Some of it makes no sense without a diagram or something.

To get rid of A you actually have to solve the equation.

7h – 5(3h – 8) = –72        Remove the brackets

7h - 15h + 40 = - 72          Combine the like terms

- 8h + 40 = - 72                Subtract 40 from both sides

- 8h = -112                        Divide by -8

    h = 14

Well the depth is a whole number so A is true.

We don't know anything about time. But the answer is positive.

C is false because B is true.

We don't know exactly what the depth of the well is.

I would pick A, but you need the entire question.

A new, trendy department store is experiencing exponential growth across America. The chain began in 2004 when it opened 16 stor
QveST [7]
The equation is y=16(1.35)ˣ.

This equation is of the form y=a(1+r)ˣ, where a is the initial amount, r is the rate of growth expressed as a decimal number, y is the total, and x is the amount of time.  For our problem, a is 16; b is 0.35 (35%=35/100=0.35).  This gives us the equation above.

Find f^-1(x) <br><br> A<br> B<br> C<br> D
inna [77]

<u><em>Answer:</em></u>

D. f⁻¹(x) = 2x + 10

<u><em>Explanation:</em></u>

<u>The given is:</u>

f(x) = \frac{1}{2}x - 5

<u>To find the inverse, follow the below procedures:</u>

<u>1- Convert f(x) to y. </u>

<u>This will give:</u>

y = \frac{1}{2} x - 5

<u>2- Swap the x and y variables.</u>

<u>This will give:</u>

x = \frac{1}{2}y - 5

<u>3- Solve for y.</u>

<u>This will give:</u>

x = \frac{1}{2}y - 5\\ \\ \frac{1}{2}y = x+5\\ \\ y = 2x+10

<u>4- Replace the y in the above step with f⁻¹(x).</u>

<u>This will give us:</u>

f⁻¹(x) = 2x + 10

Hope this helps :)

HELP ME PLS I WILL GIVE YOU THE BRAINEST
Fiesta28 [93]

Answer:

The first term should be positive

She did not distribute the -4 properly

She added \frac{2}{7} to negative -4 instead of multiplying

Step-by-step explanation:

In order to tell where she is wrong we should solve the question our selves. we are going to get the following......

-4(-3x + \frac{2}{7})= -4(-3x) +  (-4)(\frac{2}{7} )= 12x - \frac{8}{7}

So now we see that the three things she did wrong are.

The first term should be positive

She did not distribute the -4 properly

She added \frac{2}{7} to negative -4 instead of multiplying

Hope this helps :)
