X=4 you have to write it out as 6x+8=32 the subtract 8 from both sides so it will say 6x=24 then divide 6x and 24 (both sides) by 6 and it is x=4

A projectile is thrown upward so that its distance above the ground after t seconds is h =-13t2 + 390t. After how many seconds d

sertanlavr [38]

Answer:

<h3>The option C) 15 s is correct</h3><h3>Therefore the maximum height it reaches in <u>15 seconds. </u></h3>

Step-by-step explanation:

Given equation is $h =-13t^2 + 390t$

Given that a projectile is thrown upward so that its distance above the ground after t seconds is $h =-13t^2 + 390t$

<h3>To find how many seconds does it reach its maximum height:</h3>

"The standard form of a parabola's equation is expressed as :

$y=ax^2+bx+c$ .

If $a>0$ , then the parabola opens upwards;

if $a$ the parabola opens downwards."

The maximum height is the vertex of the parabola $h =-13t^2 + 390t$ which is $\frac{-b}{2a}$ .

Comparing the given equation with the standard form of parabola we get

the values of a=-13 , b=390 and c=0

The maximum height in $t=\frac{-b}{2a}$ .

Substitute the values we get

$t=-\frac{390}{2(-13)}$

$=\frac{390}{26}$

$=15$

<h3>∴ t=15 s</h3><h3>∴ The option C) 15 s is correct.</h3><h3>∴ the maximum height is the vertex of the parabola, at t reaches in 15 seconds. </h3>

A parking garage in the city charges $2.75 for the first hour and S1 25 for each additional hour or part thereof. What is the ma

Korolek [52]

Answer: The first hour is free, and the rest charges is $2.50

Let x be the time.

Let y be the total

Your equation will look like

When x < 2, y = 0

When x > 1, y = $2.50(x)

So:

1 < x < ∞ for hours, then equation will look like:

y = total amount

$2.50 is cost (remember that the first hour is for free, and so you subtract $2.50 from the total.

$2.50x - $2.50 = y should be your equation.

hope this helps
