H = 151t - 16t²

The height of the ball when it return to the ground will be 0
0 = 151t - 16t²

The zero product property is that when two numbers are being multiplied and the product is 0, one of them must be equal to 0. Therefore, we can factorize this equation:
16t² - 151t = 0
t(16t - 151t) = 0
By the zero product property:
t = 0 or 16t - 151 = 0

So t = 0 or t = 9.44 seconds

The first solution is before he releases the ball and the second is when the ball comes back to the ground. Thus, the ball's air time is 9.44 seconds.

What is the length of side a?

Bad White [126]

$\huge \bf༆ Answer ༄$

According to given figure, The Triangle BDC is a right angled Triangle (Angle D = 90°)

So, we can apply Pythagoras theorem to find the Side a (Hypotenuse)

Now, let's solve ~

$\sf \: BD {}^{2} + CD {}^{2} = BC {}^{2}$

$\sf4 {}^{2} + {3}^{2} = {a}^{2}$

$\sf16 + 9 = {a}^{2}$

$\sf \: a {}^{2} = 25$

$\sf \: a = \sqrt{25}$

$\sf \: a = 5 \: units$

Therefore, Length of side a is 5 units ~
