Answer: g(-2) = -15, g(0) = -9,

g(3) = -18

Step-by-step explanation:

g(-2) = -2*2 + 3(-2) - 5

g(-2) = -4 - 6 - 5

g(-2) = -15

g(0) = -4 - 0 - 5

g(0) = -9

g(3) = -4 - 3(3) - 5

g(3) = -4 - 9 - 5

g(3) = -18

4-20. When Susan's brother went to college, she and her two sisters evenly

Zigmanuir [339]

Each sibling got 1 poster, 8 CDS and 72 books.

<h3>How the belongings were divided </h3>

Since the belongings were divided equally, each sibling would get the same amount of belongings. In order to determine the belongings each person got, we would divide each possession by 3.

Number of poster each person got = 3/3 = 1
Number of books each person got = 216
Number of CDs each person got = 24 / 3 = 8

Help with 7 and 8 please <br> ASAP !!! Thanks

7) 52h because that's how you'd find the distance traveled if there was a number instead of a variable.(d=st)

8)525+3w because you have to add his original total to the amount of cds he will get and if he gets 3 every week that's 3w and then you add them to get the new total.

a small rocket is shot from the edge of a cliff suppose that after t seconds the rocket is y meters above the cliff where y=30t-

Natalka [10]

Answer:

Greatest height: 45 meters

Time for greatest height: 3 seconds

Height after 5 seconds: 25 meters above the cliff

Time for height of 40 meters: 7.123 seconds

Height after 7 seconds: -35 meters (35 meters below the cliff)

Step-by-step explanation:

to find the maximum height, we need to calculate the derivative of y in relation to t and then find when dy/dt = 0:

dy/dt = 30 - 10t = 0

10t = 30

t = 3 seconds

In this time, the height is:

y = 30*3 - 5*3^2 = 45 meters

After 5 seconds, the height is:

y = 30*5 - 5*5^2 = 25 meters

The time for the height of 40 meters is:

40 = 30t - 5t^2

t^2 - 6t - 8 = 0

Using Bhaskara's formula, we have:

Delta = 6^2 + 4*8 = 68

sqrt(Delta) = 8.246

t1 = (6 + 8.246) / 2 = 7.123 seconds

t2 = (6 - 8.246) / 2 = -1.123 seconds (negative value for time is not valid)

So the time when the rocket reaches 40 meters is 7.123 seconds

After 7 seconds, the height is:

y = 30*7 - 5*7^2 = -35 meters

The rocket will be 35 meters below the cliff.
