Answer:
6
Step-by-step explanation:
f(6) from the graph is -6
g(5) from the graph is -5
4*f(6)-6*g(5)=(4)(-6)-(6)(-5)=-24+30=6
Answer:
250 cubic m
Step-by-step explanation:
volume of the Olympic grid pool

The domain is the x-values. So domain is 3. Range is y-values. So range is -2, 1, 4,7, and 8. When writing either range or domain don't repeat numbers ,(example: domain is 3,3,3: wrong) and try putting the numbers from least to greatest.
This question clearly states that it is a 'find the volume' question.
Given dimensions of the object are :
Length of the object =
inches or 40.5 inches
Depth of the object = 10 inches
Height of the object is = 8 inches
So, the volume becomes =
= 3240 cubic inch
Hence, the amount of cement needed is 3240 cubic inches.
