The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot.

Nookie1986 [14]

Answer: h(3.2) =753.44 units represents the height after 3.2 seconds .

Step-by-step explanation:

Since we have given that the function

$h(t)=-16t^2+28t+500$

where t represents the time in seconds .

And we need to find the value of h(3.2)

So,

we just substitute the value of 3.2 in the function,

$h(3.2)=-16\times (3.2)^2+28(3.2)+500\\\\h(3.2)=16\times 10.24+89.6+500\\\\h(3.2)=753.44$

So, after 3.2 seconds the height will be 753.44 units.

Answer:

27525.4902

Step-by-step explanation:

First need to add the total number of employees:

14+11+17+3+5+1=51

Now multiply the salary for each number of employees then add to have the total:

14x21000+11x22800+17x24800+3x32200+5x38500+1x148300= 1403800

Now to obtain the mean value just divide the total salary by the total number of employees:
