fomenos

Answer: It will take 4 seconds for the rock to hit the water.

Step-by-step explanation:

Given : Benjamin threw a rock straight up from a cliff that was 48 ft above the water.

If the height of the rock h, in feet, after t seconds is given by the equation

$h = -16 t^2+ 52 t + 48$

To find : Time taken for the rock to hit the water.

When rock hit the water height becomes zero , i.e. put h = 0 , we get

$-16 t^2+ 52 t + 48 =0$

Divide equation by 2 , we get

$-8t^2+26t+24=0$

The Laue of x for ax²+bx+c =0 is $x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

So , $t=\frac{-26\pm\sqrt{(26^{2}-4(-8)(24))}}{2(-8)}$

$t=\dfrac{-26\pm 38}{-16}\\\\ t=-\dfrac{-26+38}{-16}=-0.75\ \ t=\dfrac{-26-38}{-16}=4$

Since t cannot be negative , so t= 4

Hence, it will take 4 seconds for the rock to hit the water.

What is the volume of a rectangle prism withe the base area of 24 and the height of 4

grandymaker [24]

Answer:

The answer to your question is Volume = 32 u³

Step-by-step explanation:

Data

The volume of a rectangular prism = ?

Area of the base = 24

height = 4

Process

1.- Write the formula to calculate the volume of a pyramid

Volume = 1/3 Area of the base x height

2.- Substitution

Volume = 1/3 (24)(4)

3.- Simplification

Volume = 96/3

4.- Result

Volume = 32 u³

The amount of orange juice in a bottle is modeled by the equation y=128-8x, where y is the number of ounces of juice in the bott

Fantom [35]

Answer:

Number of servings left is bottle $= 128-9x$

Step-by-step explanation:

The amount of orange juice in a bottle is modeled by the equation

$y=128-8x$ ---Eq (1)

Here y = number of ounces of juice in the bottle

and x = number of servings of juice poured from the bottle

Number of servings left is bottle = number of ounces of juice in the bottle -number of servings of juice poured from the bottle

Thus,

Number of servings left is bottle = y -x

Substracting x from both the sides of the above equation, we get - $y-x = 128-8x-x\\y-x = 128-9x$

Number of servings left is bottle $= 128-9x$
