Which of the following is the most profitable investment for a candy shop that earns $1 revenue per pound of candy? (5 points) G

rewona [7]

Then the most profitable investment is the first machine (third option) because for each dollar, it produces 2 pounds of candy.

<h3>Which of the following is the most profitable investment?</h3>

The first option is a worker that costs $10 per hour and produces 8lb, then this worker gives:

8lb/$10= <em>0.8 pounds per dollar.</em>

The second worker costs $12 per hour, and produces 16lb per hour, so this worker gives:

16lb/$12 = <em>1.33 pounds per dollar.</em>

The third option is a machine that cost $5 per hour and produces 10lb per hour, then:

10lb/$5 = <em>2 pound per dollar.</em>

The last option costs $8 per hour, and produces 14 pounds per hour, then:

14lb/$8 = <em>1.75 pounds per dollar.</em>

Then the most profitable investment is the first machine (third option) because for each dollar, it produces 2 pounds of candy.

Let f(x) = 4(x^2) - 3x

posledela

Answer:

(f+g)(x)=5x²-4x+3

(f-g)(x)=3x²-2x+3

(fg)(x) $=4x^4-7x^3+15x^2-9x$

$\frac{f}{g}(x)$ $=\frac{4x^2-3x}{x^2-x+3}$

Step-by-step explanation:

Given that,

f(x)=4x²-3x

g(x)=x²-x+3

(f+g)(x)

=f(x)+g(x)

=4x²-3x+x²-x+3

=(4x²+x²)+(-3x-x)+3 [ combined the like terms]

=5x²-4x+3

(f-g)(x)

=f(x)-g(x)

=4x²-3x-(x²-x+3)

=4x²-3x-x²+x-3

=(4x²-x²)+(-3x+x)-3 [ combined the like terms]

=3x²-2x+3

(fg)(x)

=f(x).g(x)

=(4x²-3x).(x²-x+3)

=4x²(x²-x+3)-3x(x²-x+3)

$=4x^4-4x^3+12x^2-3x^3+3x^2-9x$

$=4x^4+(-4x^3-3x^3)+(12x^2+3x^2)-9x$

$=4x^4-7x^3+15x^2-9x$

$\frac{f}{g}(x)$

$=\frac{f(x)}{g(x)}$

$=\frac{4x^2-3x}{x^2-x+3}$
