C(x) = 3x3 + 2x2 − 18x + 11
C(x) = 3x3 + 2x2 − 18x − 11
C(x) = 2x3 + 2x2 − 18x + 11
We have been given that the water usage at a car wash is modeled by the equation , where W is the amount of water in cubic feet and x is the number of hours the car wash is open.
The amount of decrease in water used is modeled by , where D is the amount of water in cubic feet and x is time in hours.
The function C(x) will be difference of W(x) and D(x) that is .
Upon substituting both function values in above formula, we will get:
Let us remove parenthesis.
Combine like terms.
Therefore, the function represents the water used by the car wash on a shorter day and option A is the correct choice.
Answer:
a
Step-by-step explanation:
Hey!
Adjacent angles are when two angles in a plane share a vertex and side but no common interior points.
I hope this helps;)
For this case we have that by definition, the law of the signs of multiplication states that:
So:
Option A:
It does not give a negative sign.
Option B:
It does not give a negative sign.
Option C:
It does not give a negative sign.
Option D:
The sign is negative.
Answer:
Option D
Answer: The Last One
Step-by-step explanation: The Last One Would Be A Product Of Negative
Tyanna's net proceeds algebraically?
A.
B.
C.
D.
p - x(1.04d - 22)
p - 1.04(xd – 22)
p - (1.04xd + 22)
(1.04xd +22) - p
Answer:
p - (1.04xd + 22)
Step-by-step explanation:
Tyanna bought x number of shares for d dollars ⇒ xd
paid a 4% commission ⇒ 0.04 xd
Tyanna paid = xd + 0.04xd = 1.04 xd
She sold the stock for p dollars ⇒ p
paid a flat fee of $22
The sell price = p - 22
Net = p - 22 - 1.04xd = p - (22 + 1.04 xd)
The answer is option ⇒ p - (1.04xd + 22)
Answer:
The correct option is 1.
Step-by-step explanation:
We need to find a graph that indicates an object whose velocity is zero.
Velocity is the change in displacement with respect to time.
Let d represents displacement and t represent time.
Velocity is 0.
It means the slope of line must be 0.
A horizontal line has slope 0.
In option 1, the graph represents a line whose slope is 0. It means displacement is 0 for any interval of time. So, velocity is 0.
Therefore the correct option is 1.
Answer:
The horizontal line.
Step-by-step explanation:
A horizontal line has a slope of 0. This would be expected on a graph where time is the x axis and distance is the y axis. Time would elapse but the distance would not change.
