Sinα=h/w

w=h/sinα, we are told that h=15 ft and α=70° so

w=15/sin70° ft

w≈15.96 ft (to nearest hundredth of a foot)

The Ferris wheel has a radius of 70 feet. The distance between the wheel and the ground is 4 feet. The rectangular coordinate sy
Leya [2.2K]

Answer:

The equation of the circular wheel is x^2+(y-74)^2=(70)^2.

Step-by-step explanation:

Given :

Radius of Ferris wheel r = 70 feet.

The distance between the wheel and the ground = 4 feet.

Also, the rectangular coordinate system shown has its origin on the ground directly below the center of the wheel.

So the x coordinate of center of wheel must  be 0 , and y coordinate = 70 + 4 = 74

Thus, Coordinates of center = (0,74)

The equation of circle is given by :-

(x-h)^2+(y-k)^2=r^2

Now center (h,k) = (0,74) and r = 70 , we get

x^2+(y-74)^2=(70)^2

Hence, the equation of the circular wheel is x^2+(y-74)^2=(70)^2.

The area of a rectangle is 78 square meters. The length of the rectangle is one more than twice the width. What are the dimensio
crimeas [40]

area \:  = 78

area = length \:  \times  \: width

78 = (x)(2x + 1)

x = 6

Thus the dimensions are 6 & 13
