Answer:
The value of f(3) = 13
Step-by-step explanation:
It is given that a function f(x),
f(x) = 2x²/2 + 4
<u>To find the value f(3)</u>
For that we have to substitute 3 instead of x
f(x) = 2x²/2 + 4
f(3) = 2 * (3)²/2 + 4
= (2 * 9/2 )+ 4 = 13
Therefore the value of f(3) = 13
Answer:
2110 cm³
Step-by-step explanation:
Volume = V1 + V2,
Where V1 is the volume of the pyramid, and V2 is the volume of half cylinder
V1 = ⅓×(Base area)×height
V1 = ⅓×(12.6×21.5)×8.5 = 767.55
V2 = ½×(pi×r²×h)
r = 12.6÷2 = 6.3
V2 = ½×(pi×6.3²×21.5) = 1340.415
Volume = V1 + V2
= 767.55 + 1340.415
= 2107.965
= 2110 cm³ (3 sf)

Answer:
3xy
Step-by-step explanation:
These terms are all like terms so you can add:
-2xy + 2xy = <em>0xy</em>
Now add 3xy + 0xy: 3xy

7 minutes for 49 gallons
that means 1 minutes filled 7 gallon
multiply the time by 7, that is number of gallons for each time
