First picture:
You got the first two right (good job!), so I'll just tackle the third one. If you have to compute 
, it means that you have to substitute 
in place of 
. Differently from the first two points, this will generate a new function, rather than a specific value:
Second picture:
Given the point 
highlighted in the picture, you can deduce that the base is 
units long (since it spans from 
to 
) and the height is 
units long (because it spans from to ). So, the area of the rectangle is the multiplication between base and height:
But we know that 
, so we have
The domain of this function is given by the domain of the square root: we want its argument to be non, negative, so we have
But since the problem is symmetric, the answer is
You can only see the answer 
because, if you choose 
or 
, the rectangle degenerates to a segment, and your exercise doesn't like this scenario, apparently
Answer:
a
Step-by-step explanation:
It begins at the point (0, -1200). 0 tickets sold, $1200 spent.
$5 for a ticket means that slope =5.
(600, 1800) and (0,-1200)
m= (1800-(-1200))/(600-0)=3000/600=5
slope=5
Answer is a.
I think that the answer is 63 although I could be wrong
First find the square root of -24 which would be -4.898979486 then either subtract 1 or add negative 1, it's the same thing, and that would give you -5.898979486.
Compatible numbers are rounded numbers. the compatible number for 777 is 800 , and the compatible number for 248 is 200 because I rounded to the nearest hundreds place
I hope I helped you!!!!<3
