Given :

A skyrocket is launched from a 8-foot-high platform with an initial speed of 220 feet per second.

The polynomial -16t² + 220t + 8 gives the height in feet that the skyrocket will rise in t seconds.

To Find :

How high will the rocket rise if it has a 7-second fuse?

Solution :

Since, it is given that the rocket has a fuse time of 7 seconds.

Putting value of 7 sec in given equation, we get :

Height = -16×( 7 )² + 220×( 7 ) + 8

Height = 764 m

Therefore, height of rocket in 7 second fuse is 764 m.

16) The cost, in dollars, of retaining the services of a computer repairman in Anchorville is given by
eduard

Answer:

B) 42 signifies the hourly rate, and 32 signifies the overhead charge

Step-by-step explanation:

The hourly rate is the amount of money given per hour worked. 42x basically means that for every hour, $42 are given.

As for 32, it is the overhead charge, which isn't paid every hour but rather only once. That is why it has no variable beside it.

Hope this helps!

Answer:

12

Step-by-step explanation:

We can use the pythagorean theorem giving us:

a^2+b^2=c^2

(6sqr2)^2 + (6sqr2)^2 = c^2

72+72=c^2

144=c^2

12=c
