Answer:

  C.  The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).

Step-by-step explanation:

The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.

The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.

Additionally, the x-term needs to match the result of multiplying out the factors.

  B.  (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)

  C.  (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)

The factors of C are zero when x=-1, x=5/2.

Mr. Hanky has 5 rolls of butcher paper. If you roll out a whole roll the paper would
KiRa [710]

 8,262ft^2  of a single roll . Mr. Hanky have 5 roll so Total Area = 8,262(5) = 41,310 . So , 41,310ft^2 paper does Mr. Hanky have

<u>Step-by-step explanation:</u>

Here we have , Mr. Hanky has 5 rolls of butcher paper. If you roll out a whole roll the paper would  measure 510 yards long. If the paper is 1.8 yard wide .We need to find that how many total square feet of  paper does Mr. Hanky have . Let's find out:

We know that when butcher paper will be unfolded it will be in form of a rectangle with dimensions as :

Length = 510yards\\Breadth =1.8 yards

So , Area of rectangle = Length(Breadth)

⇒ Length(Breadth)

⇒ 510(1.8)

⇒ 918yards^2

But , 1 yard = 3 feet

⇒ 918(3ft)^2

⇒ 8,262ft^2

Therefore ,  8,262ft^2  of a single roll . Mr. Hanky have 5 roll so Total Area = 8,262(5) = 41,310 . So , 41,310ft^2 paper does Mr. Hanky have .

Given below are three pairs of numbers
bearhunter [10]

Answer: in the 3 pairs we can find a rational number.

Step-by-step explanation:

A rational number can be any number written as a quotient of two integers.

The rational numbers have a finite number of decimals after the point (or periodic)

a) (-10, -9)

between those two numbers we have, for example, -9.5

and we can write this as:

-9.5 = 95/100

b) (5.91, 5.92)

between these numbers, we have the number 5.915

and we can write it as: 5.915 = 5915/1000

c) (2/3, 4/5)

between 2/3 and 4/5 we have for example the number 3/4.

because 2/3 = 0.66....

4/5 = 0.80

a number between those two is 0.75 = 3/4.
