2. angle ABE = angle MNP

Write another valid congruency statement:​

Answers

Given:

[tex]\Delta ABE\cong \Delta MNP[/tex]

To find:

The congruent angles and sides, then find the another valid congruency statement.

Solution:

We have,

[tex]\Delta ABE\cong \Delta MNP[/tex]

We know that, corresponding parts of congruent triangles are congruent (CPCTC).

Using CPCTC, we get

Angles:

[tex]\angle A\cong \angle M[/tex]

[tex]\angle B\cong \angle N[/tex]

[tex]\angle E\cong \angle P[/tex]

Sides:

[tex]AB\cong MN[/tex]

[tex]BE\cong NP[/tex]

[tex]AE\cong MP[/tex]

The another congruent statement is [tex]\Delta BEA\cong \Delta NPM[/tex].

Therefore, the required table is

Angles                                              Sides

Write the slope-intercept form of the equation of each line given the slope and y-intercept.
Slope=-1/4, y-intercept =2

Answers

Answer:

y = -1/4x+2

Step-by-step explanation:

The SIF (slope intercept form) is pretty easy once you get it down. the slope is the interger before x, and the y-intercept is b. so, if you input each number into it's spot, it would become y = -1/4x + 2.

Answers

Answer:

Step-by-step explanation:

First, we need to find the unit rate to figure out how many miles Shane rides in 1 hour. To do this it is simple, I divided 12 and 2 to get 6 miles per hour. Then we would do 22/6 but we get a decimal so it would be about 3.66666666667.

im giving 20 points

Answers

Answer:

2.7 miles

Step-by-step explanation:

25 - 10.4 - 4.5 - 7 2/5 will give you 2.7

Answer:

8 miles

Step-by-step explanation:

If we divide 70 by 50, we get the unit rate for the ratio 70 minutes for every 50 miles.

70÷50=1.4

So the runner is running 1.4 minutes per mile. We can multiply this unit rate by the number of miles:

1.4 minutes mile × 5 miles = 7 minutes

Thus it will take her 7 minutes to run 5 miles at this pace.

If it takes her 7 minutes to run 5 miles, it will take her 7÷5 = 1.4 minutes to run 6÷3=2 miles at the same pace.

If it takes her 1.4 minutes to run 5 miles, it will take her 1.4×5=7 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.

We found her pace in minutes per miles in part (a).

Answer:

The equation that models the population growth is y = 90,000(1.02)^x

Step-by-step explanation:

The formula of the exponential growth is y = a [tex](b)^{x}[/tex], where

a is the initial valueb is the factor of growth  ⇒ b > 1

Let us solve the question

∵ At x = 0, the population y = 90,000

→ That means the initial value is 90,000

a = 90,000

→ Substitute it in the form of the equation above

∴ y = 90,000 [tex](b)^{x}[/tex]

→ To find b use any values from the table to substitute x and y

∵ At x = 1, y = 91,800

∵ 91,800 = 90,000 [tex](b)^{1}[/tex]

∴ 91,800 = 90,000 b

→ Divide both sides by 90,000

∵ [tex]\frac{91,800}{90,000}[/tex] = [tex]\frac{90,000b}{90,000}[/tex]

1.02 = b

→ Substitute it in the equation above

∵ y = 90,000 [tex](1.02)^{x}[/tex]

The equation that models the population growth is y = 90,000(1.02)^x

Answer:

Step-by-step explanation:

A perfect square trinomial will be in the form of [tex]a^2[/tex] ± [tex]2ab + b^2.[/tex] A trick to factoring a perfect square trinomial would to write it as [tex](a^2[/tex]±[tex]b^2)[/tex]. (When doing this, the sign in the middle is determined by the middle sign in the original trinomial).

[tex]36x^2 -84x + 49[/tex] is known as a perfect square trinomial, too. Its first and last terms are both perfect squares (6x squared makes [tex]36x^2[/tex], 7 squared makes 49) and the middle term is 2 times the square roots of both of the other terms ( [tex](2) (7) (6x)[/tex] is [tex]84x[/tex]).

So, we can use the trick described earlier, and the answer would be [tex](6x-7)^2[/tex], also known as (6x-7) (6x-7).
