STATE THE DOMAIN OF EACH OF THE FOLLOWING RELATIONS.

Mathematics
1 answer:
Maksim231197 [3]3 years ago
7 0

Step-by-step explanation:

1.7) x = √y

The square root must be non-negative, so the domain is x ≥ 0, or in interval notation, [0, ∞).

1.8) s = (2r − 5) / (3r)

The denominator can't be 0, so r can't be 0.  So the domain is r ≠ 0, or in interval notation, (-∞, 0) (0, ∞).

1.9) ab = 12

Solve for b: b = 12/a

The denominator can't be 0, so a can't be 0.  So the domain is a ≠ 0, or in interval notation, (-∞, 0) (0, ∞).

How much cashews at $1.58 per pound must be mixed with walnuts that cost 78 cents per pound to make a mixture of 40 pounds of nu
Likurg_2 [28]

Number of pounds of cashews is 36 pounds and number of pounds of walnuts is 4 pounds.

Step-by-step explanation:

  • Step 1: Given details are cost of cashews = $1.58, cost of walnuts = 78 cents = $0.78, total weight of nuts = 40 pounds, cost of nuts per pound = $1.50
  • Step 2: Let number of pounds of cashews to be mixed be C, then number of pounds of walnuts will 40 - C. Form equation with these variables.

⇒ 1.58 C + (40-C) 0.78 = 40 × 1.50

⇒ 1.58 C + 31.2 - 0.78 C = 60

⇒ 1.58 C - 0.78 C = 60 - 31.2

⇒ 0.8 C = 28.8

⇒ C = 36 pounds

  • Step 3: Calculate number of pounds of walnuts

⇒ Number of pounds of walnuts = 40 - C = 4 pounds

How do you use the order of operations to evaluate expressions with exponents?
IgorLugansk [536]
Using BEDMAS, it would be brackets first, so anything Inside a set of brackets would be solved first, and would follow the same rule. Once the brackets have been solved, next would be the exponents. Since your brackets have been solved you can expand with the exponents. After exponents, would be anything that has to be divided or multiplied. These two operations are interchangeable based on what is more convenient or beneficial to do first. And lastly, addition and subtraction, which once again are interchangeable operations
