Answer:

Choice D is correct. Every x-value corresponds to exactly one y-value.

Step-by-step explanation:

We have given the set of ordered pairs :

{ (-5,-5) ,(-1,-2),(0,-2),(3,7),(8,9) }

We have to explain that is this set represent a function or not?

Function is a rule that assigns each input exactly one output.

In the set, each value of x has unique value of y.

From the definition of function,this set represent a function because each input has a single output.

Every x-value corresponds to exactly one y-value.

Answer:

D. Yes,because every x-value corresponds to exactly one y-value.

Step-by-step explanation:

The given ordered pairs are;

{ $(-5,-5),(-1,-2),(0,-2),(3,7),(8,9)$ }

We do not have the same x-value corresponding to more than one y-value.

We can see from the ordered pairs that every x-value corresponds to exactly one y-value.

Therefore the graph of this relation will pass the vertical line test.

Which of the following is the most profitable investment for a candy shop that earns $1 revenue per pound of candy? (5 points) G

rewona [7]

Then the most profitable investment is the first machine (third option) because for each dollar, it produces 2 pounds of candy.

<h3>Which of the following is the most profitable investment?</h3>

The first option is a worker that costs $10 per hour and produces 8lb, then this worker gives:

8lb/$10= <em>0.8 pounds per dollar.</em>

The second worker costs $12 per hour, and produces 16lb per hour, so this worker gives:

16lb/$12 = <em>1.33 pounds per dollar.</em>

The third option is a machine that cost $5 per hour and produces 10lb per hour, then:

10lb/$5 = <em>2 pound per dollar.</em>

The last option costs $8 per hour, and produces 14 pounds per hour, then:

14lb/$8 = <em>1.75 pounds per dollar.</em>

Then the most profitable investment is the first machine (third option) because for each dollar, it produces 2 pounds of candy.

A man walks along a straight path at a speed of 4 ft/s. A searchlight is located on the ground 20 ft from the path and is kept f

krek1111 [17]

Answer:

0.128rad/sec

Step-by-step explanation:

Let x represent the between the man and the point on the path

θ = the angle

dx/dt = 4 ft/s

dθ/dt = rate is the searchlight rotating when the man is 15 ft from the point on the path closest to the searchlight

tan θ = x/20 ft

Cross Multiply

20tan θ = x

dx/dt = 20sec² θ dθ/dt

dθ/dt = 1/20 × cos² θ dx/dt

dθ/dt= 1/20 × cos² θ × 4

dθ/dt = 1/5 × cos² θ

Note : cos θ = 4/5

dθ/dt = 1/5 × (4/5)²

dθ/dt = 16/125

dθ/dt = 0.128rad/sec
