<span>Okay so this is a multiplication problem, so we need to multiply the numerators and denominators of the fractions to get the product.

</span>\frac{-4}{7} × \frac{-3}{4} = \frac{12}{28}

The fraction 12/28 is not in lowest terms, so we need to reduce it. List the factors of the numerator and denominator:

Factors of <span>12: 1, 2, 3, 4, 6, 12</span>

Factors of <span>28: 1, 2, 4, 7, 14, 28</span>

4 is the largest factor of both 12 and 28, so we need to divide both the numerator and denominator by 4.

Numerator: 12 ÷ 4 = 3

Denominator: 28 ÷ 4 = 7

Write the new fraction:

\frac{3}{7}


Hope this helped :)

lora16 [44]

Answer:

The minimum cost per unit is obtained for an order of 8 units.

Step-by-step explanation:

Since the total cost is modeled by;

C(x)=5x²+320

Then;

1 unit costs; C(x)=5(1)²+320 = 325

cost per unit 325/1 = 325

8 units costs; C(x)=5(8)²+320 = 640

cost per unit = 640/8 = 80

80 units costs; C(x)=5(80)²+320 = 32320

Cost per unit = 32320/80 = 404

The minimum cost per unit is obtained for an order of 8 units.

Important guyz.....

Answer:

When two functions combine in a way that the output of one function becomes the input of the other, the function is a composite function.

Step-by-step explanation:

In mathematics, the composition of a function is a step-wise application. For example, the function f: A→ B & g: B→ C can be composed to form a function that maps x in A to g(f(x)) in C. All sets are non-empty sets. A composite function is denoted by (g o f) (x) = g (f(x)). The notation g o f is read as “g of f”
