Use slope formula to find the missing coordinate.<br><br> (r, 1) and (5, -7) Slope = 8/3
Lena [83]

Answer:

r=8

Step-by-step explanation:

The formula for slope is

m = (y2-y1)/ (x2-x1)

Substitute in what we know.

8/3 = (-7-1)/(5-r)

Simplify

8/3 = -8/(5-r)

We can use cross products to help us solve.

8 * (5-r) = 3 * (-8)

divide each side by 8

8/8 * (5-r) = 3 * (-8)/8

5-r = -3

Subtract 5 from each side

5-r-5 = -3-5

-r = -8

Multiply by -1

r = 8

Brooklyn Bridge is 5,985 ft long and 85 ft wide. What distance is one sixth of its length
I am Lyosha [343]

Answer:

The distance is 997.5 ft.

Step-by-step explanation:

Given:

Length of Brooklyn Bridge = 5,985 ft.

Width of Brooklyn Bridge = 85 ft.

We need to find the Distance

Distance = \frac{1}{6}\times lenght

Substituting the value of length to find distance we get;

Distance = \frac{1}{6}\times 5985 = 997.5 ft.

Hence Distance is 997.5 ft.

A sector of a circle of radius is 15Cm, and angle 216 degrees is bent to form a cone. What is base radius of the cone and the ve
-Dominant- [34]

Answer:

Step-by-step explanation:

Radius r = 15

Circumference = 2πr = 30π cm

Circumference of cone = arc length of sector

= 30π × 216°/360°

= 18π cm

Radius of base of cone = 18π/(2π) = 9 cm

Slant height of cone = radius of circle = 15 cm

Height of cone = √(15² - 9²) = 12 cm
