the height y of a ball thrown by a child is given by y = -1/12x^2 + 2x + 4. how high is the ball when it is at its maximum heigh
zhuklara [117]

Answer:

The height of ball when it is at maximum height is 12  unit

Step-by-step explanation:

Given as :

A ball is thrown by child to height y

And y as a function  x is y = -\frac{1}{12}x^{2}+2x+4

So, for maximum value of height ,

\frac{\partial y}{\partial x}  = 0

Or , \frac{\partial (-\frac{1}{12}x^{2}+2x+4)}{\partial x} = 0

Or, -\frac{1}{12}(2x)+2 = 0

Or, \frac{1}{12}(2x) = 2

or,  x = 12

Hence The height of ball when it is at maximum height is 12  unit  Answer

nikitadnepr [17]

Answer: each eraser cost 5 dollors                

Step-by-step explanation: Simplifying

25 = 5 + 4e

Solving

25 = 5 + 4e

Solving for variable 'e'.

Move all terms containing e to the left, all other terms to the right.

Add '-4e' to each side of the equation.

25 + -4e = 5 + 4e + -4e

Combine like terms: 4e + -4e = 0

25 + -4e = 5 + 0

25 + -4e = 5

Add '-25' to each side of the equation.

25 + -25 + -4e = 5 + -25

Combine like terms: 25 + -25 = 0

0 + -4e = 5 + -25

-4e = 5 + -25

Combine like terms: 5 + -25 = -20

-4e = -20

Divide each side by '-4'.

e = 5

Simplifying

e = 5
