Answer:

Step-by-step explanation:

I am assuming the question is asking which x value plugged into the function will give you a zero so

(-1)3 -8(-1)2 -23(-1)+30

so that simplyfiys to -1-8(1)+23+30

so that is -1-8+53

so -9+53

= 44

trying 3 we get

(3)3-8(3)2-23(3)+30

so that is 27 -72-69+30

and that is not zero

trying -10

we get

(-10)3-8(-10)2-23(-10)+30

which is -1000- 800+230+30

that is not zero so lastly trying 1 we get

(1)3-8(1)2-23(1)+30

which is 1-8-23+30

which is -7+7 which is zero

1. Which of the following questions has a constant of

garik1379 [7]

Answer:

In B) y = x/7 , the constant of proportionality is 7.

Step-by-step explanation:

Two quantities X and Y are said to be in proportion if and only if

X = kY or, $\frac{X}{Y} = k$ ,

where k = Proportionality Constant.

Here, 7 is the constant of proportionality. Then,

A . y = 14x

here, $\frac{y}{x} = 14$ ≠ 7

B . y = x/7

here, $\frac{x}{y} = 7$ = constant of proportionality .

C. y = x

here, $\frac{y}{x} = 1$ ≠ 7

Suppose a cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cyl

IrinaVladis [17]

Answer: option A

Step-by-step explanation:

The volume of a cylinder can be calculated with the formula:

$V=\pi r^2h$

Where r is the radius and h is the height of the cylinder.

The radius is diameter divided by 2, then:

$r=\frac{18ft}{2}\\\\r=9ft$

Substitute the radius into the formula. Then you get the following equation that can be used to find V, the volume of the cylinder:

$V=\pi (9)^2h$

Find the greatest common factor

Lerok [7]

Answer:

(3b + 4) is the greatest common factor

Step-by-step explanation:

$3b(2b- 3)+4(2b-3) = 0 \\ {6b}^{2} - 9b + 8b - 12 = 0 \\ {6b}^{2} - b - 12 = 0 \\ {6b}^{2} - 9b + 8b - 12 = 0 \\ 3b(2b - 3) + 4(2b - 3) = 0 \\ (2b - 3)(3b + 4) = 0$

Subtract the following polynomials, then place the answer in the proper location on the grid.

melamori03 [73]

When we add or subtract polynomials, the addition or subtraction is applied to the coefficients of the terms of equal powers.

For the given polynomials, we are required to do subtraction as follows:
(-4.1 x^2 + 0.9 x - 9.8) - (1.7 x^2 - 2.4 x - 1.6)
= -4.1 x^2 + 0.9 x - 9.8 - 1.7 x^2 + 2.4 x + 1.6
= (-4.1-1.7) x^2 + (0.9+2.4) x + (-9.8+1.6)
= -5.8 x^2 + 3.3 x - 8.2

The final expression (solution) is:
-5.8 x^2 + 3.3 x - 8.2
