The function h=-16t^2 +1700 gives you the height h, of an object in feet, at t seconds. How long will it take the object to hit
garik1379 [7]

Answer:

The object will hit the ground after 10.308 seconds.

Step-by-step explanation:

h(t) = -16t² + 1700

If you graphed this function, the object would be shown hitting the ground when it crosses the x-axis, in other words, when h = 0. So, to find the answer, just set h(t) equal to 0 and solve.

-16t² + 1700 = 0   Plug this into a calculator if you have one.

t = -10.308 and t = 10.308

Since time can't be negative, your answer will be the positive value, 10.308.

What is the lateral area of the cone to the nearest whole number? The figure is not drawn to
Sveta_85 [38]

Answer:

The lateral surface area of the cone is 25120\ m^2.

Step-by-step explanation:

We have.

Height of a cone is 60 m

Diameter of a cone is 10 m

Radius, r = 80 m

The lateral surface area of a cone is given by :

A=\pi rl

l is slant height of the cone,

l=\sqrt{60^2+80^2} =100\ m

Plugging all values in above formula,

A=3.14\times 80\times 100\\\\A=25120\ m^2

So, the lateral surface area of the cone is 25120\ m^2.
