Consider the complementary angles shown below. Find the value of x. X + 4 3x + 2

Answers

Answer:

x = 21

Step-by-step explanation:

For the complementary angles, the sum of two angles is equal to 90 degrees.

ATQ,

3x+2+x+4 = 90

Taking like terms together,

3x+x+6=90

4x+6=90

4x = 84

x = 21

So, the value of x is equal to 21.

Answer

y=5x−10.

Explanation:

The slope of a line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.

We have that x1=3, y1=5, x2=2, y2=0.

Plug the given values into the formula for slope: m=(0)−(5)(2)−(3)=−5−1=5.

Now, the y-intercept is b=y1−m⋅x1 (or b=y2−m⋅x2, the result is the same).

b=5−(5)⋅(3)=−10.

Finally, the equation of the line can be written in the form y=mx+b.

y=5x−10.

Answer:

The slope of the line is m=5.

The equation of the line in the slope-intercept form is y=5x−10.

The equation of the line in the point-slope form is y−5=5(x−3).

The equation of the line in the point-slope form is y=5(x−2).

The general equation of the line is 5x−y−10=0.

A 300 room hotel can rent every one of its rooms at $80 per room. For each $1 increase in rent,
3 fewer rooms are rented. How much should the hotel charge for each room to maximize its
daily revenue? What is the maximum daily revenue?
y = (300 – 3x)(80 + 1x)

you would distribute, 300 times 80 is 2400 and -3x times 1x is -3x so the equation would be y=2400-3x

Answer:
( y - 10 )( y - 2 )

Explanation:
First break down the equation y^2 -12y +20.
The equation now becomes y^2 -2y -10y +20. This is called creating and using the sum-product pattern. Now you need to find the common factor between both pairs to simplify the next equation, y ( y - 2 ) - 10 ( y- 2 ). ( y - 2 ) is the common factor. Now all you do is rewrite your equation in factored form. In this case, ( y - 10 )( y - 2 ). Comes out to be your answer.

The base of a right prism is a regular hexagon with side 4. The height of the prism is 6. Find the lateral area and volume.

Answers

Answer:

(i) The lateral area of the right prism is 144 square units

(ii) The volume of the right prism is 249.42 cubic units.

Step-by-step explanation:

The lateral area of the right prism is calculated as;

Lateral area = perimeter of the base x height

Given;

a side of the hexagon base, s = 4

height of the prism = 6

perimeter of the hexagon = 6s

Lateral area = (6 x 4) x 6

Lateral area = 144 square units

Volume of the right prism is calculated as;

V = base area x height

base area of a hexagon = [tex]\frac{3\sqrt{3} \ \times \ s^2}{2}[/tex]

Volume of the right prism = [tex]\frac{3\sqrt{3} \ \times \ s^2}{2} \ \ \times \ \ h\\\\[/tex]

[tex]V = \frac{3\sqrt{3} \ \times \ (4)^2}{2} \ \ \times \ \ 6\\\\V = 249.42 \ cubic \ units[/tex]
