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

:( A=? B=? please help me

Helen [10]

a= 16x+16

b= 40x + 15

Step-by-step explanation:

We know that perimeter of a rectangle is

$2(l + b)$

So therefore

$2(8x + 3 + 5) = a$

$= > 16x+ 6 + 10 = a$

$= > 16x + 16 = a$

Answer= A) that is perimeter is 16x+16

We know that area of a rectangle is l×b

So therefore

$(8x + 3) \times 5$

$= 40x + 15$

Answer = b) that is area is 40x + 15
