7 0

Answer:

\sqrt{10}

Step-by-step explanation:

g(4) = \sqrt{(4)^2 - (4) - 2}  \\\\g(4) = \sqrt{16 - 4 - 2}  \\\\g(4) = \sqrt{16 - 6} \\\\g(4) = \sqrt{10}

You can't simplify this anymore

Hope this helps! : )

Well, the slope for each side is simple.

All you have to do to remember slope is rise over run.

So for example:
 For Vertices E and F the Slope would be 3/9
For Vertices  G to H the slope would be 3/9
For vertices G to F the slope would be 6/2
For vertices H to E the slope would be 6/2

 
What do you notice about slopes on opposite sides?
Answer:
( H to E,and G to F) Have the same slope
 (And G to H and E to F.) Have the same slope.


What do you notice about slopes of adjacent lines? 
adjacent means adjoining or next to. So can you figure this question out? Using the information above?

Which equation can be used to solve for b?<br> B<br> 5 cm<br> 10 cm<br> 30°
kati45 [8]

The Question is Incomplete The complete question with figure is below.

Answer:

Therefore the equation to solve for b is

\tan 30 = \dfrac{5}{b}

Step-by-step explanation:

Given:

In Right Angle Triangle ABC

∠C = 90°

BC = 5 cm

AB = 10 cm

∠A = 30°

To Find:

b = ?

Solution:

In Right Angle Triangle ABC Tangent identity we have

\tan A = \dfrac{\textrm{side opposite to angle A}}{\textrm{side adjacent to angle A}}

Substituting the values we get

\tan 30 = \dfrac{BC}{AC}\\\\\tan 30 = \dfrac{5}{b}

Therefore the equation to solve for b is

\tan 30 = \dfrac{5}{b}

steve made a mistake in writing a two step equation. Instead of multiplying by 3 and adding 7, he multiplied by 7 and added 3 to
rjkz [21]

Answer:

The correct answer of the problem is 1.

Step-by-step explanation:

Let the original number on which the wrong procedure is applied is x.

Now, Steve multiplied by 7 and then added 3 to get the answer of - 11.

So, 7x + 3 = - 11

⇒ 7x = - 14

⇒ x = - 2

Now, the correct step to get the answer is multiplying by 3 and adding 7.

Hence, the correct answer of the problem is (- 2) × 3 + 7 = - 6 + 7 = 1 (Answer)

Help out here asap the last it says how many units wide is the rectangle​
Marat540 [252]

Answer:

5m^5n^4

Step-by-step explanation:

Divide the length (5m^4n^2) into the area (25m^9n^6) to obtain the width:

25m^9n^6

----------------- = 5 m^(9-4)n(6-2)  = 5 m^5n^4

 5 m^4n^2

The width of the rectangle is 5m^5n^4.
