Answer:
72 novels
Step-by-step explanation:
A number of assumptions are involved regarding operating environment, utilization fraction, and probability of failure as a function of time. The precise meanings of the words "average", "supposed to last", "maximum", and "expect" are involved. The details are too arcane to go into here.
(450 hours)/(6 1/4 hours/novel)
= (450/(25/4)) novels
= (450*4/25) novels
= 72 novels

Answer:
The turning point of the graph is at (3,-16)
Step-by-step explanation:
The general equation of curve is given as:
y = x² + ax + b
The two point for which the equation satisfies is (0,-7) and (7,0).
Substitute (0,-7) in the general equation:
y = x² + ax + b
-7 = 0² + a(0) + b
b = -7
Substitute (7,0) in the general equation:
y = x² + ax + b
0 = 7² + 7a + b
Where b = -7
0 = 49 + 7a - 7
0 = 42 + 7a
a = -6
The equation of the curve is:
a = -6 and b = -7
y = x² + ax + b
y = x² - 6x - 7
Graph of the equation is attached below.
We can see that the the turning point of the graph is at (3,-16)
The system of equations of two unknowns is formulated and solved.




The fraction that satisfies the request is
, since in
the negative signs are canceled and the first fraction is obtained.
2-5/8-6/8=16/8-5/8-6/8=5/8 pizza slices left
3/8+7/8=10/8=1 2/8 pizza slices altogether
hope it helps:))
