Step-by-step explanation:

1. Perimeter = 2 ( 5+4) = <u>18 cm</u>

Area = 5 × 4 = <u>20 cm^2</u>

2. Perimeter = 2 (5+5) = <u>20 cm</u>

Area = 5 × 5 = <u>25 cm^2</u>

3. Cups of seed needed per sq. meter = Area of the rectangle backyard

= 6 × 7

= <u>42 </u><u>cups</u><u> </u><u>of</u><u> </u><u>seed</u>

4. Feet of fence needed = Perimeter of the Square garden

= 2(8+8)

<u>= 32 feet</u>

5. Perimeter of rectangular quilt = 2 (4+6) feet

= <u>20 feet</u>

6. Area of the room = 9 feet × 8 feet

= <u>72 feet^2</u>

Howard is designing a chair swing ride. The swing ropes are 4 44 meters long, and in full swing they tilt in an angle of 2 3 ∘ 2
qaws [65]

Question:

Howard is designing a chair swing ride. The swing ropes are 4 meters long, and in full swing they tilt in an angle of 23°. Howard wants the chairs to be 3.5 meters above the ground in full swing. How tall should the pole of the swing ride be? Round your final answer to the nearest hundredth.

Answer:

7.18 meters

Step-by-step explanation:

Given:

Length of rope, L = 4 m

Angle = 23°

Height of chair, H= 3.5 m

In this question, we are to asked to find the height of the pole of the swing ride.

Let X represent the height of the pole of the swing ride.

Let's first find the length of pole from the top of the swing ride. Thus, we have:

cos \theta = \frac{h}{L}

Substituting figures, we have:

cos(23) = \frac{h}{4}

Let's make h subject of the formula.

h = 4cos(23) = 3.68

The length of pole from the top of the swing ride is 3.68 meters

To find the height of the pole of the swing ride, we have:

X = h + H

X = 3.68 + 3.5

X = 7.18

Height of the pole of the swing ride is 7.18 meters

Range = -4= g(x)

Therefore, g(x) = -3x+2

or, -4=3x +2

or, 3x= -4-2

or, 3x= -6

or, x= -6/3 = -2

OPTION A is the correct answer.
