Answer:
Multiply the rate per hour by the number of hours (n) and add the deposit.
A)
Bike shop x: c = 2.75n + 3.00
Bike shop z: c = 1.75n + 7.00
B) to find when they will cost the same set the equations equal to each other and solve for n:
2.75n + 3.00 = 1.75n + 7.00
Subtract 3 from each side:
2.75n = 1.75n + 4.00
Subtract 1.75n from both sides:
1.00n = 4.00
Divide both sides by 1:
n = 4 hours
Answer:
Alternate Interior Angles
Answer:
( 
, 0) and (8, 
)
Step-by-step explanation:
Curve is concave downward when the second derivative is negative.
y' = 
, by the Fundamental Theorem of Calculus
y'' = 
, which has a denominator that is always positive. The numerator 
is negative when x > 0 and when x < 8. So that is when y'' is negative, and consequently when the curve y is concave down.
