Answer:

6 seconds after it is launched

Step-by-step explanation:

h(t) = -4t² + 16t + 48

The balloon is at ground level when it lands.

When it is launched, t = 0, and h(0) = 48

When it lands, at time t, h(t) = 0.

-4t² + 16t + 48 = 0

t² - 4t - 12 = 0

(t - 6)(t + 2) = 0

t = 6 or t = -2

The balloon will hit the ground 6 seconds after it is launched.

In what quadrant would the ordered pair (-5, 4) be located?<br><br> I<br> II<br> III<br> IV
statuscvo [17]
Ok, so
 Quadrants are found on coordinate planes. So the first number tells you to go on the X axis. It goes this way ---------
you look on the left side side of the origin (zero) and go to -5
since the second umber will be found on the Y axis, and is positive, go up to 4.
That is how you find your point.  The qudrants are counted like this.

3 4
The answer is Quadrant 2

The square below represents one whole.
zaharov [31]

Answer:

6 percent

Step-by-step explanation:

6/100 is shaded. This is the same thing as 0.06. Once I move the decimal two places to the right, I get 6. (I move the decimal place because percents are out of 100, so two decimal places.) This means 6 percent.
