Answer:

0

Step-by-step explanation:

(f-g)(x) = 12-sqrt(x)

plugging in 144, we get 12 - 12 = 0

one could also do f(x)-g(x) which would yield 24-24=0

When dropped, a super ball will bounce back to 80% of its peak height,continuing on in this way for each bounce.

Liono4ka [1.6K]

An expression for the height of the nth bounce is 0.80X^N = Height.

<h3><u>Equations</u></h3>

Since when dropped, a super ball will bounce back to 80% of its peak height, continuing on in this way for each bounce, to determine an expression for the height of the nth bounce the following calculation must be performed:

X = Initial value
80% = 0.80
N = Number of times the ball bounces
0.80X^N = Height

Therefore, an expression for the height of the nth bounce is 0.80X^N = Height.

Help meeeeeeeeeeeeeeee pleaseee!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

For the equation F(x) = ax² + bx + c we have:

maximum value if a<0
minimum value if a>0

F(x) = -3x² + 18x + 3 ⇒ a = -3, b = 18

a < 0 ⇒ the function has a maximum value

Quadratic function has the maximum value (or minimum) at vertex of its parabola.

The maximum value is k at x=h where: $h=\dfrac{-b}{2a}$ and k = F(h)

$h=\dfrac{-18}{2\cdot(-3)}=3\\\\F(3)=-3\cdot3^2+18\cdot3+3=-27+54+3=30$

Therefore:

<h3> The function has a maximum value of 30 at x = 3</h3>

Nanda Yueh and Lane Zuriff sell homes for ERA Realty. Over the past 6 months they sold 136 homes. Nanda sold 3 times as many hom

Marta_Voda [28]

Answer:

Lane sold 34 homes.

Nanda sold 102 homes.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

Nanda sold x homes

Lane sold y homes

Over the past 6 months they sold 136 homes.

This means that $x + y = 136$

Nanda sold 3 times as many homes as Lane.

This means that $x = 3y$

Replacing in the first equation:

$x + y = 136$

$3y + y = 136$

$4y = 136$

$y = \frac{136}{4} = 34$

Lane sold 34 homes.

$x = 3y = 34*3 = 102$

Nanda sold 102 homes.
