Step-by-step explanation:
$78.75/5 hr=$15.75/hr
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.

Step-by-step explanation:
Answer:
a = – 8
Step-by-step explanation:
From the question:
When P(x) = 2x³ – ax² + 4x – 4 is divided by x – 1, it gives a reminder of 10.
To obtain the value of a, we shall equate x – 1 to 0 as illustrated below:
x – 1 = 0
x = 0 + 1
x = 1
Next, we shall substitute the value of x into 2x³ – ax² + 4x – 4 and equating it to 10 as illustrated below:
2x³ – ax² + 4x – 4 = 10
x = 1
2(1)³ – a(1)² + 4(1) – 4 = 10
2 – a + 4 – 4 = 10
2 – a = 10
Collect like terms
– a = 10 – 2
– a = 8
Divide through by –1
a = – 8
Therefore, the value of a is –8.
V-39=-16
V-39+39=-16+39
V=23
