Answer:
Maximum volume error = ±540 cm³
Relative error = 0.02
Percentage error = 2%
Step-by-step explanation:
Relative error : The ratio of volume error to the total volume.
Percentage error: The product of relative error and 100.
The volume of a cube is = 
v =x³
Differentiate with respect to x
Here are x = 30 cm and dx= ±0.2 cm
∴ dv = 3×(30 cm)² (±0.2 cm)
=±540 cm³
The volume of the cube = 30³ cm ³ = 27,000 cm³
Then the relative error
= 0.02.
The percentage error
= (0.02×100)
=2%
Answer:
By unitary method
40/10 = 4km / litre
So,
4*25 = 100 km
The car covers 100km with 25 litres of fuel
Hope this helps
Please mark me as the brainliest
Thank you
That would be 8, its in the center so forget 9 or 7.

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The tricky part is always what is in the brackets with the x. It is highly anti intuitive.
(x + 2) moves the graph left, not right as you might think. So from this, only C and D can be considered as answers.
Since the 2 is with the x, that's how many units left you will go -- 2 units.
C is the only possible answer.
The - 7 tells you it will move 7 units down. The 7 with a minus acts the way you think it should. It goes down which is what normally happens on a graph. A mnus number outside the brackets means down.
