Answers

Answer 1
Answer:

Determine how much cost one ounce in both cases:

1. Brand A: 14 ounces for $44.66, then 1 ounce costs (\$44.66)/(14) =\$3.19.

2. Brand B: 20 ounces for $63.80, then 1 ounce costs (\$63.80)/(20) =\$3.19.

As you can see both brands cost the same per ounce.

Answer: correct choice is A.
Answer 2
Answer:

Both brands have the same cost which is 3.19 dollars/ounce. The correct answer is option A.

What is the division operation?

In mathematics, divides left-hand operands into right-hand operands in the division operation.

To determine which brand is the better buy, we need to compare the cost per ounce of each brand.

For brand A:

Cost per ounce = 44.66/14

Apply the division operation,

Cost per ounce = 3.19 dollars/ounce

For brand B:

Cost per ounce = 63.80/20

Cost per ounce = 3.19 dollars/ounce

Therefore, both brands have the same cost per ounce.

Hence, the correct answer is option A.

Which of the following is a polynomial with roots 4, −5, and 7?Question 4 options:

1) f(x) = x3 − 6x2 − 27x + 140
2) f(x) = x3 − 6x2 − 20x + 27
3) f(x) = x3 − 20x2 − 27x + 35
4) f(x) = x3 − 20x2 − 35x + 140

Answers

If x = 4, then the factor is (x - 4); if x = -5, then the factor is (x + 5); if x = 7, then the factor is (x - 7).  We need to FOIL all these together to get a third degree polynomial.  (x - 4)(x + 5) = (x^2 + x - 20).  Now multiply that by (x- 7):  (x^2+x-20)(x-7) = x^3+x^2-20x-7x^2-7x+140.  Combine like terms to get  x^3-6x^2-27x+140,  the first choice above.

Answer: 1) f(x) = x3 − 6x2 − 27x + 140
