A golf ball is hit with an initial velocity of 100 feet per second. The height of the golf ball can be represented by the equati

LenaWriter [7]

Answer:

6.25 seconds

Step-by-step explanation:

<u>Using the the equation </u>

h = 100t − 16t^2

<u>The ball hits the ground, when h = 0, solving below equation:</u>

100t − 16t^2 = 0
4t(25 - 4t) = 0
t = 0 seconds, this is the starting point when ball was hit
25 - 4t = 0 ⇒ 4t = 25 ⇒ t= 25/4 = 6.25 seconds later the ball hits the ground

A right square pyramid is pictured below. if l is 15 cm and x is 18 cm, what is the surface area of the pyramid?

Nady [450]

Answer:

The surface area of square pyramid is 953.64 cm² .

Step-by-step explanation:

Given as for a square pyramid :

The height of pyramid = l = 15 cm

The base of square pyramid = x = 18 cm

Now,

The surface area of square Pyramid = $b^{2} + 2b\times \sqrt{\frac{b^{2}}{4}+h^{2}}$

or , The surface area of square Pyramid = $x^{2} + 2x\times \sqrt{\frac{x^{2}}{4}+l^{2}}$

Or, The surface area of square Pyramid = $18^{2} + 36\times \sqrt{\frac{18^{2}}{4}+15^{2}}$

Or, The surface area of square Pyramid = 324 + 36 × $\sqrt{81 + 225}$

or, The surface area of square Pyramid = 324 + 36 × 17.49

Or , The surface area of square Pyramid = 324 + 629.64 = 953.64 cm²

Hence The surface area of square pyramid is 953.64 cm² . Answer
