Answer:
The report is 960 words long.
Step-by-step explanation:
The handwritten book report is 4 pages long and the typed report is 3 pages long.
Now, it is given that typing at a steady rate of 20 words per minute, it takes 48 minutes to enter the report into soft copy.
So, the required number of words of the report is (20 × 48) = 960 words.
Hence, the report is 960 words long. (Answer)
Answer:
f ( - 2 ) = - 12
Step-by-step explanation:
f ( - 2 ) = - 3 ( -2 )^2
then you do the exponent first so
- 3 ( 4 )
now you multpily the - 3 and 4
you get - 12
Answer:

Step-by-step explanation:
We have
this equals to
now we try to agrupate to have exponent of 2 that we can cancel
we can take out the ones with exponent from the root

Volume of a cone:


r²h
Plug the radius and volume in the formula.


10²h = 942
Divide both sides by

.

10²h = 2,826
Divide both sides by pi.
10²h = 900
Divide both sides by 10² (100).
h = 9
The cone's height is 9 units.
So because it's x^2 that means it's a parabola. The 3 before it is it's stretch factor (slope, so instead of going over one up one it goes over one up 3)
