Sometimes I think the questioners could at least say thank you.

Here is the answer.

A sphere with a radius of 3 cm has the same volume as a cone with a radius of 6 cm. What is the height of the cone?

The height h above the roadway of the main cable of the Golden Gate Bridge can be modeled by the function h(x) = 1/9000x^2-7/15x+500, where x is the distance in feet from the left tower.

a. Complete the square, and write the function in vertex form.

b. What is the vertex, and what does it represent?

c. The left and right towers have the same height. What is the distance between them?

    Disdance: d=4200 feet.

AB = sqrt(4²+4²+4²) = sqrt(16+16+16) = sqrt(16*3)=4*sqrt3 = 6.9

A store sells white scarves and red scarves . A white scarf is $3 and a red scarf is $5. One day the store sold 12 scarves for $50. What is the total number of scarves sold on that day?

-4(x + 4) > x + 7.

 -4x - 16 > x + 7   | -x + 16

        -5x > 23       | : (-5)

           x < -4.6

[-inf , -4.6]
