Answer:
f(-3)=56
Step-by-step explanation:
When evaluating a specific input for a function, you just plug that input in for x.
So in this case, f(-3)=5(-3)^2-2(-3)+5
f(-3)=5(-3)^2-2(-3)+5
f(-3)=5(9)+6+5
f(-3)=45+6+5
f(-3)=56
Answer:
Janet reads 13.865 pages in 4.7 minutes.
Step-by-step explanation:
Given that Janet can read 2.95 pages of a book in a minute.
- unit rate = 2.95 pages/per minute
As she reads for 4.7 minutes.
We just need to multiply 4.7 minutes with 2.95 to determine total pages she would read in 4.7 minutes.
i.e.
4.7 × 2.95 = 13.865 pages
Therefore, Janet reads 13.865 pages in 4.7 minutes.

Answer:
1120 cm^3
Step-by-step explanation:
Volume of the ice cube = B * h
B = 20 cm^2
h = 4 cm
Volume = 20 * 4 = 80 cm^3
This volume is for one cube holder in the tray.
There are 7 * 2 such holders
There are 14 holders
Total volume of the holders =
14 * 80 =
1120 cubic cm
