Step-by-step explanation:

So the first 1 on the left is A=2lw+2lh+2wh

Then the first 1 on the right the property you use is distribute

Then the rest I don’t know I’m sorry

The path of a volley ball thrown over a net is modeled with the function A(x) = -0.02x2 + 0.6x + 5, where x is

LiRa [457]

Answer:

The ball travel horizontally 37 feet before it hits the ground

Step-by-step explanation:

we have

$A(x)=-0.02x^2+0.6x+5$

where

x ----> is the horizontal distance in feet

A ---> is the altitude of the ball, in feet.

we know that

When the ball hit the ground, the altitude of the ball is equal to zero

For A(x)=0

$-0.02x^2+0.6x+5=0$

solve the quadratic equation

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$-0.02x^2+0.6x+5=0$

$a=-0.02\\b=0.6\\c=5$

substitute in the formula

$x=\frac{-0.6\pm\sqrt{0.6^{2}-4(-0.02)(5)}} {2(-0.02)}$

$x=\frac{-0.6\pm\sqrt{0.76}} {-0.04}$

$x=\frac{-0.6\pm0.87} {-0.04}$

$x=\frac{-0.6+0.87} {-0.04}=-6.75$

$x=\frac{-0.6-0.87} {-0.04}=36.75$

therefore

The ball travel horizontally 37 feet before it hits the ground

[5x+10y+15z=60<br> [2x+4y+6z=60<br> [x+2y+3z=60

Alla [95]

9514 1404 393

Answer:

no solution

Step-by-step explanation:

The equations are inconsistent. The set of equations reduces to ...

x + 2y + 3z = 12

x + 2y + 3z = 30

x + 2y + 3z = 60

No values of x, y, and z can satisfy all three equations. There is no solution.

Mike is working on solving the exponential equation 37x = 12; however, he is not quite sure where to start. Using complete sente

Oksana_A [137]

Mike would first have to divid 37 from 12 and he would then find x
