Answer:

(2/5a²x)( -1/5x²a) = -2/25a³x³

Step-by-step explanation:

We have given two terms.

2/5a²x and -1/5x²a

We have to find product of given terms.

We use following formula to solve this.

yᵃyᵇ = yᵃ⁺ᵇ

The product is:

(2/5a²x)( -1/5x²a) =2/5a²x . -1/5x²a

Combining like terms, we have

(2/5a²x)( -1/5x²a) = (2/5)(-1/5)(a²a)(xx²)

(2/5a²x)( -1/5x²a) = (-2/25)(a²⁺¹)(x¹⁺²)

(2/5a²x)( -1/5x²a) =( -2/25)(a³)(x³)

(2/5a²x)( -1/5x²a) = -2/25a³x³

Answer: -\frac{2}{25}a^{3}x^{3}

Step-by-step explanation:

1. The problem asked for the product of \frac{2}{5}a^{2}x and -\frac{1}{5}x^{2}a, therefore, you must mutliply them, as you can see below:

2. According the exponents propertiess, when you have a multiplication of two powers that has the equal base, you must add the exponents. THerefore, you have the following result:

 (\frac{2}{5}a^{2}x)(-\frac{1}{5}x^{2}a)=-\frac{2}{25}a^{3}x^{3}

What are the solutions to the equation?<br> 7x^3=28x
11Alexandr11 [23.1K]

7x³ = 28x is our equation. We want its solutions.

When you have x and different powers, set the whole thing equal to zero.

7x³ = 28x

7x³ - 28x = 0

Now notice there's a common x in both terms. Let's factor it out.

x (7x² - 28) = 0

As 7 is a factor of 7 and 28, it too can be factored out.

x (7) (x² - 4) = 0

We can further factor x² - 4. We want a pair of numbers that multiply to 4 and whose sum is zero. The pairs are 1 and 4, 2 and 2. If we add 2 and -2 we get zero.

x (7) (x - 2) (x + 2) = 0

Now we use the Zero Product Property - if some product multiplies to zero, so do its pieces.

x = 0        -----> so x = 0

7 = 0       -----> no solution

x - 2 = 0   ----> so x = 2   after adding 2 to both sides

x + 2 = 0  ---> so = x - 2  after subtracting 2 to both sides


Thus the solutions are x = 0, x = 2, x = -2.

A company sells doughnuts. They incur a fixed cost of $23000 for rent, insurance, and other expenses. It costs $0.1 to produce e
olasank [31]

Answer:

C(x) = 0.1x+23000

Step-by-step explanation:

Given that a company sells doughnuts. They incur a fixed cost of $23000 for rent, insurance, and other expenses. It costs $0.1 to produce each doughnut. The company sells each doughnut for $0.2.

Let X be the no of units produced

Then we have variable cost = 0.1x

Fixed cost = 23000 (irrespective of value of x)

Total cost

C(x) = 0.1x+23000

where C represents the total cost and x no of units produced.

Revenue function would be

R(x) = 0.2x assuming all doughnuts are sold.

Profit function would be

P(X) = 0.1x-23000
