Answer:
$77.4
Step-by-step explanation:
GIVEN: On the trip from KC to Springfield, the church van consumed
gallons of gas to go
miles. If gas cost
per gallon.
TO FIND: Cost of a round trip to Springfield.
SOLUTION:
Distance of springfield from KC 
As it is a round trip total distance 
As
gallons gas used for
miles distance
gas required for
mile
gallons
gas required for
miles
gallons
cost of one gallon of gas 
cost of
gallons of gas 
Hence cost of roundtrip to Springfield is $77.4
Answer:
76%
Step-by-step explanation:
First, we know that 6 tables of 6 are already seated. We can go ahead and multiply 6 by 6, which is 36.
This means that 36 of the 150 seats are already taken.
But, we want to find the amount of seats that are still empty. So, we subtract 36 from 150 to get 114 seats.
The question is asking for the percentage, so we can divide 114 by 150 seats to get 0.76. Then, we have to move the decimal to the right 2 spaces to get 76%
Step-by-step explanation:
First, find the zeroes of the parabola







So the zeroes or where the curve crosses the x axis is at 4 and -3.
Now, we take the derivative of the function.

Plug in -3, and 4 into the derivative function


So at x=-3, our slope of the tangent line is -7 and must pass through (-3,0). So we use point slope formula.



At x=4, our slope of tangent line is 7, and pass through (4,0) so


So the equations of tangent is
