Answer:

The height of the pyramid is 50\ in

Step-by-step explanation:

we know that

The volume of a triangular pyramid is equal to

V=\frac{1}{3}BH

where

B is the area of the base

H is the height of the pyramid

we have

V=1,800\ in^{3}

The area of the base B is equal to

B=\frac{1}{2}(12)(18)=108\ in^{2}

substitute and solve for H

1,800=\frac{1}{3}(108)H

5,400=(108)H

H=5,400/(108)=50\ in

A rock is thrown from the top of a tall building.The distance in feet between the rock and the ground t seconds after thrown is
marusya05 [52]

Answer:

0.448 seconds

Step-by-step explanation:

d = -16t² -4t + 412

find t when d = 407

substituting d = 407 into the equation:

407 = -16t² -4t + 412 (subtract 407 from both sides)

-16t² -4t + 412 - 407 = 0

-16t² -4t + 5 = 0 (multiply both sides by -1)

16t² + 4t - 5 = 0  

solving using your method of choice (i.e completing the square or using the quadratic equation), you will end up with

t = (-1/8) (1 + √21)= -0.70 seconds (not possible because time cannot be negative)

or

t = (-1/8) (1 -√21) = 0.448 seconds (answer)
