Hello There!

In order for a relation to be a function the x value cannot repeat

In answer choice  A the x value 3 repeats therefore a cannot be the answer

In answer choice B the x value -1 repeats therefore B cannot be the answer

In answer choice C the x value -1 repeats therefore C cannot be the answer

In answer choice D none of the x values repeat so d is your answer

Here is the complete question

A window shaped like a parallelogram has an area of 73 2/3 square feet. The height of the window is 8 2/3 feet. How long is the base of the window?

A parallelogram is  quadrilateral that has two pairs of parallel sides. The opposite sides  equal in length

Area = base x height

73 2/3 = 8 2/3 x base

divide 73 2/3  by 8 2/3

221/3 x 3/26 = 8 1/2 feet

Answer:

A) ∠L = 67.5°

B) ∠E = 112.5°

C) ∠K = 112.5°

D) ∠H = 67.5°

Step-by-step explanation:

A) ∠L is alternate interior to ∠F so it is equal to 67.5°

B) ∠E is supplementary to ∠F so ∠E = 180° - 67.5° - 112.5°

C) ∠K is alternate exterior to ∠E so ∠K = 112.5°

D) ∠H is a vertical angle to ∠F so ∠H is 67.5°

Answer:

5) r=40 gals/min

6) r= 125 mm/hr

7) $2600

8) d = 36 in

9) h= 1176 m

Step-by-step explanation:

5) r=v/r

r= 15,600 gals ÷ 390 mins

r= 40 gals/min

6) r=v/t

r= 1000mm ÷ 8 hrs

r= 125 mm/hr

7) $4500 - $1900 = $2600

8) C = Pi x d

c/Pi =d

113 in/3.14 = d

d = 36 in

9) Formula for h

h = 2 x a/b

h = 2 (84m2/12m)

h = 2 (7056/12)

h = 2(588)

h = 1176 m

trigonometry

Step-by-step explanation:

Have a great day!

Answer:

Abackyard = (3w + 5)2

Apool = w(w + 10)

Asurround = (3w + 5)2 - w(w + 10)

A=8w2+20w+25

The expression for the area surrounding the pool after the pool is

installed is  (3w + 5)² - w(w + 10).

The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.

We have,

The pool needs to have a length of 10 feet more than the width.

Then, the area of pool is

= w(w + 10)

and, The backyard have sides measuring 5 feet more than 3 times the width of the pool.

Then, area of backyard

= (3w + 5)²

Now, the area surrounding the pool after the pool is

=  (3w + 5)² - w(w + 10)

Answer:

2x=110 degree

Answer:

26ft

Step-by-step explanation:

Complete Question:

The equation a = 26w gives the area of a (in square feet) of a rectangle dance floor with a width of w feet. Find its length

Formula for calculating the area of a rectangle is expressed as shown;

Area of a rectangle = Length * Width

Given the equation a = 26w that gives the area of a rectangle

On comparing with the formula;

Length * Width = 26w

Length = 26ft (by comparison)

Hence the length of the rectangle is 26ft

Answer:

32 feet

Step-by-step explanation:

given the following;

Length of wire = 40feet = hypotenuse

Base of the pole = 24 feet = adjacent

Required

Height of the pole (opposite)

Using the pythagoras theorem;

hyp^2 = opp^2 + adj^2

40^2 = 24^2 + opp^2

1600 = 576 +opp^2

opp^2 = 1600 - 576

opp^2 = 1024

opp = √1024

opp = 32feet

Hence the utility pole is 32feet tall

Step-by-step explanation:

To first answer; this we would need to figure out the cost of one taco

Since there are already 4 we would need to divide the price by the amount so you would do

6.00/4=1.5

And now that we have the price of one we can multiply it by 10

1.5*10=15

Answer:

18.44°

Step-by-step explanation:

The line of sight of the player to the rim, the height of the eyes of the player above the floor, the distance of the player from the center of the rim and the height of the center of the rim above the ground form a trapezium. The height  of the center of the rim above the ground and  the height of the eyes of the player above the floor form parallel sides.

Since The height  of the center of the rim above the ground = 10 ft and the height of the eyes of the player above the floor = 5 ft, the height of the triangular part of the trapezium is 10 ft - 5 ft = 5 ft. The base of this triangle is parallel to the side of distance of the player from the center of the rim = 15 ft. So the base of this triangle is 15 ft. Since the angle of elevation Ф of the line of sight of the player to the rim is adjacent to this base = 15ft and opposite to the height of the triangle = 5ft,

By trigonometric ratios,

tanФ =opposite/adjacent = 5 ft/15 ft = 1/3

Ф = tan⁻¹(1/3)

Ф = 18.435°

Ф ≅ 18.44°

Answer:

6 inches

Step-by-step explanation:

basically, first write an equation

2x^2 = x^2 + 5x + 6

then simplify this into

x^2 = 5x + 6

then use sum-product pattern and factor

(x - 6)(x + 1) = 0

then split into two equations

x - 6 = 0, x + 1 = 0

so, you have x = 6 and x = -1

because it can't be negative, 6 is your answer
