Vanessa uses the expressions (3x2 + 5x + 10) and (x2 – 3x – 1) to represent the length and width of her patio. Which expression
Brut [27]

The area of rectangle with length l and width w is

A=l\cdot w.

If the length of rectangle is expressed as l=3x^2 + 5x + 10 and the width of rectangle is expressed as w=x^2-3x-1, then the area of rectangle is

A=(3x^2 + 5x + 10)(x^2-3x-1)=3x^4-4x^3-8x^2-35x-10.

The cost of producing hard drives has three parts: cost of materials, cost of labor, and cost of equipment. To produce x hard dr
LenKa [72]
Let x represent the number of hard drives produced.
The first thing we need to do is convert 10 cents to dollars:
10cents( \frac{1dollar}{100cents} )=0.1dollar. Now, we know that the the cost of materials is 30 dollars and the cost of labor is  0.1 dollars, so the total coast to produce x hard drives will be: 30+0.1=30.1x.
Now the only thing left is add t<span>he cost of equipment to complete our function:
</span>f(x)=30.1x+10000

We can conclude that the equation that could represent the cost function for making x hard drives is <span>f(x)=30.1x+10,000</span>

Please need help on this one
Nookie1986 [14]
The answer is 130°
Because it is a circle, the angles have to all add up to 360°. So if you add up the two known angles, and subtract that sum from 360, you will get 130°

Left f(x)=x+1 and g(x)=1/x the graph of (f•g) (x) is shown below
Nikolay [14]

Answer:

Range of the function → (-∞, 1)∪(1, ∞)

Step-by-step explanation:

Two function has been given as,

f(x) = (x + 1)

and g(x) = \frac{1}{x}

Then (fog)(x) = f[g(x)]

Now f[g(x)] = \frac{1}{x}+1

As shown in the graph,

Domain of the graph is (-∞, 0) ∪ (0, ∞) [Since vertical asymptote of the function is x = 0, so x = 0 will not be included in the domain]

And the range is (-∞, 1) ∪ (1, ∞) [Since horizontal asymptote is y = 1, so y = 1 will not be included in the range]
