A ball is thrown from the top of the school. The height of the ball (in feet) written in

seropon [69]

Answer:

3 seconds

Step-by-step explanation:

When the ball hits the ground, the height will be 0. Therefore, you can substitute 0 in for the value of f(t), hence the equation will be:

0 = -16t^2 + 32t + 48

You can then factor out -16:

0 = t^2 - 2t - 3

Factor:

0 = (t-3)(t+1)
t = 3, -1

However -1 is an extraneous solution because time cannot be negative. Therefore, the answer is 3 seconds.

Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month. Her friend Kate’s hair is 16 inches long and grows

Gelneren [198K]

<h3>18 months will pass before the two friends have the same hair length</h3>

<em><u>Solution:</u></em>

Let "x" be the number of months

Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month

$Equation : 13 + \frac{2}{3}x ------- eqn\ 1$

Her friend Kate’s hair is 16 inches long and grows at an average rate of ½ in per month

$Equation: 16 + \frac{1}{2}x ----- eqn\ 2$

<em><u>For two friends to have the same hair length, eqn 1 must be equal to eqn 2</u></em>

$13 + \frac{2x}{3} = 16 + \frac{x}{2}\\\\\frac{2x}{3} - \frac{x}{2} = 16 - 13\\\\\frac{4x}{6} - \frac{3x}{6} = 3\\\\x = 18$

Thus 18 months will pass before the two friends have the same hair length

Determine the type of triangle that has side lengths of 18, 24, and 42.

NNADVOKAT [17]

This is not a triangle since 1 side is equal to the sum of the other 2 sides , whereas it should be lesser:

42 < 24+18; so 42<42 Impossible
