Answer:
7/1000
Step-by-step explanation:
I'm assuming the blueprint shows 1 inch is equal to 10 ft. This means that 1 inch on the blueprint corresponds to 10 feet in real life.
We have the ratio
1 inch: 10 feet
If we multiply both sides by 0.5 then,
0.5*(1 inch) : 0.5*(10 ft)
0.5 inch : 5 feet
So 0.5 inches (aka half an inch) on the blueprint corresponds to 5 feet in real life.
Answer: A) 5 feet
Answer:
-1
Step-by-step explanation:
See the attachment for the polynomial long division. The constant in the quotient is -1.
_____
Here, there is a remainder of -x. If there were no remainder the constant in the quotient is the ratio of the constant in the dividend to the constant in the divisor: -2/2 = -1.
That could be a first guess in a "guess and check" solution approach.
<em>Guess</em>: first term of binomial quotient is (2x^3)/x^2 = 2x; last term of binomial quotient is -2/2 = -1. So, the quotient is guessed to be (2x -1).
<em>Check</em>: (2x -1)(x^2 -x +2) = 2x^3 -3x^2 +5x -2
Subtracting this from the actual dividend gives a remainder of -x. This has a lower degree than the divisor, so no further adjustment of the quotient is required.
Hello from MrBillDoesMath!
Answer:
(x + 6) (2 x - 9)
Discussion:
6 and -9 are the factors of the constant term as 6 * (-9) = -54
The x term is given by -9x + 12x = 3x (multiply the factorization out)
