Rachel has a box in the shape of a prism with a square base. The capacity of the box is 150 cubic inches. The height of the box

V = s²h

150 = s²h 
150 = s²(3/2)s 
(2/3)150 = s³ 
100 = s³ 
s = ∛100 (approx 4.642 in)

Answer:

x = -3, 0, or 7

Step-by-step explanation:

After removing common factors, the remaining quadratic can be factored by comparison to the factored form of a quadratic.

Write the equation in standard form.

4x³ -16x² -84x = 0

Factor out the common factor from all terms.

= 4x(x² -4x -21) = 0

Compare to the factored form of a quadratic:

(x +a)(x +b) = x² +(a+b)x +ab

This tells you the constants 'a' and 'b' in the factors can be found by considering ...

(a+b) = -4 . . . . the coefficient of the x term of the quadratic

ab = -21 . . . . . the constant term of the quadratic

It is often helpful to list factor pairs of the constant:

-21 = (-21)(1) = (-7)(3) . . . . integer pairs that have a negative sum

The sums of these pairs are -20 and -4. We are interested in the latter. We can choose ...

a = -7, b = 3

Put it all together.

4x³ -16x² -84 = (4x)(x -7)(x +3) = 0 . . . . . factored form of the equation

Apply the zero product rule. This rule tells you the product of factors will be zero when one or more of the factors is zero:

4x = 0 ⇒ x = 0

x -7 = 0 ⇒ x = 7

x +3 = 0 ⇒ x = -3

Solutions to the equation are x ∈ {-3, 0, 7}.

Additional comment

What we did in Step 3 is sometimes referred to as the X-method of factoring a quadratic. The constant (ab product) is put at the top of the X, and the sum (a+b) is put at the bottom. The sides of the X are filled in with values that match the product and sum: -7 and 3. The method is modified slightly if the coefficient of x² is not 1.

A graphing calculator often provides a quick and easy method of finding the real zeros of a polynomial.

Help me please this was due yesturday

Step-by-step explanation:

Slope intercept form is

$y = mx + b$

where m is the slope( average rate of change) and b is the

y intercept( the y value when x is zero).

When x=0, y is 2. This means b=2

Slope is change in y value/ change in x value. Another obvious arbitrary point we are given is (-8,0).

So let use the formula we given.

So our slope is 1/4 so our equation is

1/4x+2

3. Identify the subsets of real numbers that apply to /100/5

Alina [70]

Using number sets, it is found that the correct classification of the number is:

C. rational number, integer, whole number, natural number , real number.

Numbers are classified as:

Whole, which is all positive numbers and zero, also called natural.
Integers, which is the set of whole numbers plus negatives.
Rational, which is the set of integer numbers plus terminating or repeating decimals.
Irrational, which are non terminating decimals.
Real, which are the sum of rational and irrational.

In this problem, the number given is:

$\frac{100}{5} = 20$

Which is a whole(natural) number, thus it is also integer, rational and real, and the correct option is C.
