Answer:
2x^2
Step-by-step explanation:
The coefficients of the terms in this expression are 8, 4, and 18.
The largest number that you can divide all of them with and get a whole number is 2.
So, 2 is part of our greatest common factor.
These terms also have the variable x. The exponent of the smallest x term is 2, so x^2 is the other part of our greatest common factor.
To determine the maxima and minima of the polynomial, differentiate the given based on x and equate to 0.
C(x) = 400x - 0.2x²
dC(x) / dt = 400 - 0.4 x = 0
The value of x is 1000. This is the value of the maxima. As the value of C(x) continously becomes lesser as the value of x is set higher, the minima is not identified. Substitute x to the original equation,
C(x) = (400)(1000) - 0.2(1000²) = $ 200,000
Thus, the answer is letter B.
Answer:
-3
Step-by-step explanation:
p(x) = x^2-6x+5
Let x= 4
p(4) = 4^2-6(4)+5
Exponents first
= 16 -6(4) +5
Multiply
= 16 -24 +5
Add and subtract
= -8+5
= -3
Answer:
133.06 miles per hour
Step-by-step explanation:
Distance =2438.9 miles
Time=18 hours 20 minutes.
First we convert the time to hour
60 minutes = 1 hour
20 minutes=(20/60) hour=0.33
Therefore her time=18+0.33 hour=18.33hour
We are to determine the average speed of her flight in miles per hour.
rate=distance/time
=2438.9/18.33
=133.06 miles per hour
Her average speed is 133.06 miles per hour
