You're uncle is having a new roof installed in his house. The roof is a square pyramid. The side length of the base of the roof
Kaylis [27]

Answer:

The height of the roof in his house is 72.43 ft.

Step-by-step explanation:

The volume of square pyramid is :

V=\frac13 Bh

B= area of the base.

h= the height.

Given that,

The roof is a square pyramid in shape. The volume of the roof is 18929.333 cubic feet.

The side length of the base of the roof is 28 feet.

Since the base of the roof is square in shape.

The area of the square is = side²

The area of the base is =(28×28) square feet

                                       =784  square feet

Assume the height of the roof be h ft.

Then, the volume of the roof is = \frac13 Bh

                                                   =\frac13 \times 784 \times h square feet.

According to the problem,

\frac13 \times 784 \times h= 18929.3333

\Rightarrow h=\frac{18929.3333\times 3}{28}

\Rightarrow h\approx 72.43 ft.

The height of the roof in his roof is 72.43 ft.

Plz help ASAP! I will mark brainliest if correct
MaRussiya [10]
A = L^2
A = L^2 = 2^2 + 4^2 (Pythagorean’s theorem)
A = L^2 = 20
Therefore the area of the square is 20 units square.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th
oksian1 [2.3K]

Answer:

17 seconds

Step-by-step explanation:

Solution:-

The trajectory of a rocket launched is modeled by a parabolic path via a quadratic equation as follows:

                               y = -16x^2 + 266x +102

Where,

                   y: The height of the rocket from ground

                   x: The time taken since rocket launch

We are to determine the time ( x ) it takes for the rocket to hit the ground. This can be determined by setting the quantity ( y ) to zero as follows

                             y = -16x^2 + 266x +102 = 0\\\\ -16x^2 + 266x +102 = 0

solve the quadratic equation using quadratic formula as follows:

                             x = \frac{-b +/- \sqrt{b^2 - 4ac} }{2a} \\\\x = \frac{-266 +/- \sqrt{266^2 - 4*(-16)*(102)} }{2*(-16)} \\\\x = \frac{-266 +/- 278 }{-32} \\\\x = 8.3125 +/- 8.6875\\\\x = 17 , -0.375

Answer: Ignore the negative value for time " -0.375 ". Hence, the rocket hits the ground at time t = 17 seconds
