============================================================

1. 0 or -3

2. 0 or 4

3. -2 or 3

4. 0 or 1/2

5. -2 or 3

6. 0 or 5

7. 0 or 7

8. 0 or -2
============================================================

9. Substitute 0 for h in "h = -16x^2 + 16x" then solve for x
0 = -16x^2 + 16x

Subtract -16x^2+16x from both sides.
0−(−16x2+16x)=−16x2+16x−(−16x2+16x)
16x2−16x=0

Factor the left side of the equation
16x(x−1)=0

Set factors to equal 0
16x=0 or x−1=0
x = 0 or x = 1

VARVARA [1.3K]

Answer:

6 samples

Step-by-step explanation:

Given :

Sample size, = n

Standard deviation, = 6000

Margin of Error = 2000

Confidence interval, α = 95%

Zcritical at 95% = 1.96

n = (Zcritical * σ) / margin of error

n = (1.96 * 6000) /2000

n = 11760 / 2000

n = 5.88

n = 6 samples

You bought a magazine for $5 and four erasers. you spent a total of $25.

Magazine cost: 5$ each
Eraser cost: X$ each

Total cost is the number of items (1 magazine) times the cost of each item (5$). We don't know the cost of each eraser, so we represent that using a variable, X.

1(5) + 4(X) = 25

5 + 4X = 25

subtract 5 from both sides

4X = 25 - 5

4X = 20

divide both sides by 4

X = 20/4

X = 5

Each eraser cost 5$

Answer:

A. 2x(x+1)(x-6); 0, -1, 6

Step-by-step explanation:

The zeros are the values of x that make the factors zero. That is, for binomial factors, they are the opposite of the constant in the binomial factor. For example, the factor (x+1) will be zero when x = -1, so that -1+1 = 0.

This observation eliminates choices B and C.

The product of binomial factors looks like this:

(x +a)(x +b) = x² +(a+b)x +ab . . . . . x-coefficient is (a+b)

Once 2x is factored from the given polynomial, the resulting quadratic is ...

x^2 -5x -6

This means the sum of the constants in the binomial terms must be -5. That will only be the case for choice A.
