Answer:

A. 16 m

B. At t = 2 and t = 6

C. 8 seconds

Step-by-step explanation:

Maximum height is at the vertex

(4,16). So maximum height is 16 m at t = 4

The rocket is at a height of 12m at two distinct times:

At 2 seconds and again at 6 seconds

The rocket is in air when the height is not zero, I.e between t=0 and t=8

8-0 = 8 seconds

Millimeters<br> Equal 15 centimeters 4 millimeters
Svetradugi [14.3K]

154mm

we know that  1cm = 10 mm

 therefore      15cm= 10*15 mm

                               =  150 mm

and 4 mm

we get total mm= 15cm +4mm

                          = 150mm+4mm

                           = 154 mm                  

mm stands for millimeters and cm stand for centimeters

How to solve X^4-19x^2+48=0
ZanzabumX [31]
Two numbers that add up to -19 and multiply to 48 are -16 and -3:

(x^4-19x^2+48)=0\\(x^2-16)(x^2-3)=0\\(x+4)(x-4)(x^2-3)=0

So, the solutions come from each parentheses:  x+4=0, x-4=0, and x^2-3=0.

x+4=0
x = -4

x-4=0
x = 4

x^2-3=0
x^2 = 3
x = +/- √3

So, the solutions are -4, -√3, √3, and 4.

The internet was used by 30% of the population of a state in 2008. If 3200 people were surveyed, how many in the survey were usi
andrew-mc [135]
1. We know that 30% expressed as a decimal is 0.30

Since 30% of people were using the internet, 0.30*3200 is our answer.
3200*0.30= 960.

Therefore 960 people were using the internet out of the 3200 surveyed.
