Answer:

<em>The average cost is less than 100 when the number of items x is greater than 2</em>

Step-by-step explanation:

The cost equation is $C(x) = 10x + 180$

The average cost $Cp = \frac{C(x)}{x}$

We want to know when the cost Cp is less than 100.

So

$Cp$

$Cp = \frac{C(x)}{x}$

$10 + \frac{180}{x}$

For $x> 0$

$\frac{180}{90}$

$x> 2$

The average cost is less than 100 when $x>2$

The area of the parallelogram is 936 sq ft what’s the height

Makovka662 [10]

Answer:

h = 24 ft

Step-by-step explanation:

A = 936 ft^2, b = 39 ft.

A = bh

Divide both sides by b:

h = A/b = 936 ft / 39 ft = 24 ft

Simplify x^1/3(x^1/2+2x^2)

Marizza181 [45]

Answer:

$x^{5/6 } + 2\cdot x^{7/3}$

Step-by-step explanation:

Let be $x^{1/3}\cdot (x^{1/2} + 2\cdot x^{2})$ , which can be simplified solely by algebraic means. We proceed to describe all the steps needed for simplification:

1) $x^{1/3}\cdot (x^{1/2} + 2\cdot x^{2})$ Given.

2) $x^{1/3}\cdot x^{1/2} + 2\cdot (x^{1/3}\cdot x^{2})$ Distributive and associative properties.

3) $x^{5/6 } + 2\cdot x^{7/3}$ $a^{m}\cdot a^{n} = a^{m+n}$ /Result

Find the area of the figure. (Sides meet at right angles.) <br>

ikadub [295]

Answer:

44ft^2

Step-by-step explanation:

Break the shape into 3 rectangles, two 3 by 2's and one 4 by 8. (Get 4 by subtracting 3 from 7 for the left and right most side)

3 x 2 = 6 ft^2

since there's two rectangles you end up 6 + 6 so you get 12 ft^2

then 4 x 8 = 32 ft^2

add 32 and 12, get 44 ft^2

Factor f(x) = 15x^3 - 15x^2 - 90x completely and determine the exact value(s) of the zero(s) and enter them as a comma separated

Illusion [34]

Answer:

$x=-2,0,3$

Step-by-step explanation:

We have been given a function $f(x)=15x^3-15x^2-90x$ . We are asked to find the zeros of our given function.

To find the zeros of our given function, we will equate our given function by 0 as shown below:

$15x^3-15x^2-90x=0$

Now, we will factor our equation. We can see that all terms of our equation a common factor that is $15x$ .

Upon factoring out $15x$ , we will get:

$15x(x^2-x-6)=0$

Now, we will split the middle term of our equation into parts, whose sum is $-1$ and whose product is $-6$ . We know such two numbers are $-3\text{ and }2$ .

$15x(x^2-3x+2x-6)=0$

$15x((x^2-3x)+(2x-6))=0$

$15x(x(x-3)+2(x-3))=0$

$15x(x-3)(x+2)=0$

Now, we will use zero product property to find the zeros of our given function.

$15x=0\text{ (or) }(x-3)=0\text{ (or) }(x+2)=0$

$15x=0\text{ (or) }x-3=0\text{ (or) }x+2=0$

$\frac{15x}{15}=\frac{0}{15}\text{ (or) }x-3=0\text{ (or) }x+2=0$

$x=0\text{ (or) }x=3\text{ (or) }x=-2$

Therefore, the zeros of our given function are $x=-2,0,3$ .
