Answer: (c * d)(x) =
4x^3 + 18x^2 - 10x</h3>
Work Shown:
I'm assuming the dot means multiplication. If so, then,
(c * d)(x) = c(x)*d(x)
(c * d)(x) = [ c(x) ] * [ d(x) ]
(c * d)(x) = (4x-2)(x^2+5x) .... substitution
(c * d)(x) = 4x(x^2+5x) - 2(x^2+5x) ... distribute
(c * d)(x) = 4x(x^2)+4x(5x) - 2(x^2)-2(5x) ... distribute again
(c * d)(x) = 4x^3 + 20x^2 - 2x^2 - 10x
(c * d)(x) = 4x^3 + 18x^2 - 10x

Answer:
15 ft
Step-by-step explanation:
If every 1/4 of an inch is a foot, than every inch is 4 feet.
1 inch = 4ft
3 inches = 12ft
1/4 + 1/4 + 1/4 = 3/4
3/4=3 ft
12+3=15ft
Answer:
A. exactly 0.50
Step-by-step explanation:
We have been given a statement. We are asked to choose the correct option about given statement.
We know that every histogram has 5 points summary.
1st point is known as minimum point, 2nd point is first quartile, 3rd point is median, 4th point is upper quartile and 5th point is maximum point.
In a normal distribution 25% of the data points are to the left 1st quartile, 50% of the data points are to the left of median and 75% of the data points are to the left 2nd quartile.
Therefore, exactly 0.50 of the total area which must be to the left of the median.
Congrats on getting that far!
From here, simplify the equation by dividing each term by the greatest common factor: 6.
36B + 30C = 822600 becomes 6B + 5C = 137100
Now you have stackable simultaneous equations that you can easily work with:
6B + 5C = 137100
B + C = 24500
Multiply the terms in the second equation by either 6 or 5 so that you can subtract the second equation from the first equation and cancel out the B or C, respectively.
Example:
6B + 5C = 137100
minus 5B + 5C = 122500
equals B = 14600
Then plug your answer into the B + C = 24500 equation to find C.
Finally plug B and C into the A + C + B = 49000 equation to get A.
