Answer:
Volume of green house = 54 m³
Step-by-step explanation:
Given:
Base = 3m x 9m
Height of house = 2 m
Find:
Volume of green house
Computation:
Volume = lbh
Volume of green house = 3m x 9m x 2m
Volume of green house = 54 m³
 
        
             
        
        
        
Answer:
Two straight lines with slopes m and m' are parallel when m = m'
Two straight lines with slopes m and m' are perpendicular when m × m' = - 1. 
Step-by-step explanation:
Let us assume that the two non-vertical lines in the slope-intercept form are
y = mx + c ........... (1) and  
y = m'x + c' ............ (2)
If those two lines are parallel then we can say the slope of them will be the same i.e. m = m'
Now, if given two straight lines (1) and (2) are perpendicular to each other and neither of them is parallel to the axes, then we can write m × m' = - 1. (Answer)

Answer: x>8
Step-by-step explanation: when we plug g(x) into f(x) we get sqrt7(1/x-8) and when you graph (as shown below) this you see that the graph has a vertical asymptote of 8 therefore the domain is x>8
