a machine worked for 5 hours and used 4 kilowatts of electricity. the machine used____of a kilowatt each hour it worked

Answers

The question is meaningless. It uses "kilowatt" completely incorrectly.

"Watt" and "kilowatt" are rates at which energy is used, NOT
amounts of energy.

The question is a lot like saying that a car traveled for 5 hours at
4 miles per hour, so how many miles per hour did it travel each
hour it drove ?

======================================

If a machine used energy at the rate of 4 kilowatts when it's
running, then it uses 4 kilowatt-hours of energy during every
hour that it runs.

If it runs for 5 hours, then it uses

(4 kilowatts x 5 hours) = 20 kilowatt-hours

of energy during that time.

Parallel, perpendicular, or neither

Answers

Answer: Parallel.

Step-by-step explanation:

Because both points run across the x-axis, never cross, and are in straight lines, the points would be known as parallel to one another.

Answer:

z = 3.3

Step-by-step explanation:

Given

2.2 = z - 1.1 ( add 1.1 to both sides )

3.3 = z

The range of y = sin(x) is _______. a. 0 ≤ y ≤ 1 b. -1 ≤ y ≤ 1 c. y ≤ 1 d. y ≥ 0

Answers

Answer:

$\sf\nb.\ -1 \le y \le 1$

Explanation:

$\sf\n\textsf{For all real values of x, value of sin(x) will always be greater than or equal to -1 }\n\textsf{and less than or equal to 1.}$

$\textsf{Here is a graph of sine function. From the graph, it is clear that the y-value of sine}\n\textsf{is never above 1 or below -1. So the range of y = sinx is }\sf{-1\le y \le 1.}$

Final answer:

The range of the sin(x) function is -1 ≤ y ≤ 1, because the output of the sin(x) function oscillates between -1 and 1 regardless of the input 'x' value.

Explanation:

The range of a function represents the set of all possible output (y) values that the function can produce. The sine function, sin(x), oscillates between -1 and 1. This is because the maximum height a sine wave can reach is 1 (at π/2 and its equivalents) and its minimal height is -1 (at 3π/2 and its equivalents). Therefore, no matter what value of 'x' you insert into the sin(x) function, the maximum and minimum values for the output 'y' is 1 and -1 respectively. Hence, the correct answer is -1 ≤ y ≤ 1.

Find the unknown side of the right triangle. Round to the nearest thousandths. One side is 9yd, the other side is 12 yd.

Answers

You haven't told us whether 9 and 12 are the two legs of the triangle, or whether the 12yd is the longest side.

If the 9 and the 12 are the two legs, then:
C² = A² + B²
C² = 81 + 144
C² = 225
C = 15 yd

If the 12 is the longest side, then:
(12)² = (9)² + B²
B² = (12)² - (9)² = 144 - 81 = 63
B = √63 = 7.937yd (rounded)

Find three rational numbers equivalent to each of the following rational numbers. (i)−2/5 (ii)3/7

Answers

Step-by-step explanation:

(i)

-2/5 = -4/10 = -6/15 = -8/20

(ii)

3/7 = 6/14 = 9/21 = 12/28

we simply multiply top and bottom (numerator and denominator) by the same number.
