Choose all of the following relationships that represent functions. please help!!

ser-zykov [4K]

The rule of a function is:
You CANNOT have one x-value with multiple different y values in the same function. You can however have different x values with the same y value.
Also for reference: independent means x value and dependent means y- value.

The first answer is not a function because as you can see there is one x-value with multiple y values.

second answer IS a function because as I said before you can have different x values with the same y value

third answer is a function again because you can have different x values with same y value

number four isn't a function bc again the -2 x value has 2 different y Values.

Question 1

mamaluj [8]

Answer:

The maximum volume of space that 1,000 BTUs will cool is 400 cubic foot.

Step-by-step explanation:

Given : A total of 1,000 BTUs are needed to cool a space. If 2.5 BTUs are needed to cool 1 cubic foot of space.

To find : What is the maximum volume of space that 1,000 BTUs will cool?

Solution :

Applying unitary method,

2.5 BTU are needed to cool 1 cubic foot of space.

So, 1 BTU are needed to cool $\frac{1}{2.5}$ cubic foot of space.

Then,1000 BTU are needed to cool $\frac{1}{2.5}\times 1000$ cubic foot of space.

i.e. 1000 BTU are needed to cool 400 cubic foot of space.

Therefore, the maximum volume of space that 1,000 BTUs will cool is 400 cubic foot.

Identify the middle line for the function: f (t) = 5sec(3t − π) + 1

sergiy2304 [10]

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

(t) = 0 gives
-24t + 60 = 0
t = 2.5
For this t, the second derivative s"(t) = -24 is negative. And so, s(t) is maximum for t = 2.5.
Maximum height is S = -12(2.5)^2 + 60(2.5) +8 = 233ft

Ramon travels 20 miles in 20 minutes, how many miles can he travel in 120 minutes?

Elis [28]

Answer: 120

Step-by-step explanation:

20 divided by 20 is 1.

We have to multiply this by 120.

120 x 1 = 120. It is the answer.

What is the area of this question.

frez [133]

The area of a circle is \pi r^2, where r is the radius of the circle. The diameter of a circle is the length of a line that passes through the center of the circle and stops at the perimeter of circle. The radius of a circle is half the diameter. Divide the diameter by 2 to find the radius.
1. 2.8 m / 2 = 1.4 m
2 . $\pi (1.2m)^2$ : Plug in the value we just found for r.
3. $\pi 1.44m^2$ : Use the order of operations (PEMDAS).
4. $\pi * 1.44m^2 = ~4.52 m^2$
The area of the circle is equal to $4.52 m^2.$
