Identify the domain and range

Answers

Answer 1

Answer:

Answer:

Domain: (-∞, ∞), or x∈R, or -∞<x<∞

Range: (-∞, ∞), or y∈R, or -∞<y<∞

Step-by-step explanation:

Domain and range are all real numbers. Domain is all values of x, range is all values of y.

Domain: (-∞, ∞), or x∈R, or -∞<x<∞

Range: (-∞, ∞), or y∈R, or -∞<y<∞

You are paid $78 for 6 and a half hours of work. What is your rate of pay?

Answers

The most important part of the problem lies in the fact that the hours have to be converted to minutes before starting to solve the problem.
1 hour = 60 minutes
6 and half hours = (6 * 60) + 30 minutes
   = 360 + 30
   = 390 minutes
So the payment for 390 minutes is = 78 dollars
Then
The payment for 60 minutes = (78/390) * 60
   = 2 * 6 dollars
   = 12 dollars
So the rate of pay given is $12 per hour. I hope the procedure is easy enough for you to understand. You can always use this method for solving similar type of problems.

$78/ (6 1/2 hours)= $12/hour.

The rate of pay is $12 per hour~

How do you turn fractions into decemals

Answers

To turn fractions into decimals, we just have to divide the numerator by the denominator. It is very simple. Let me show you by giving an example ;

Let us convert 1/2 into a decimal. To do this, we divide 1 by 2. We get it 0.5.

Now, let us convert 30 / 5 into a decimal. by dividing 30 by 5 we get 6. Thus, 30/5 into decimal we get 6.0 , which we write as 6.

Divide the numurator to the denominator:)

Simplify six-hundred thirty over 10

Answers

630/10

Lets divide!

630/10 = 63
10/10 = 1

63/1 = 63

Answer: 63

The answer is 63 because six-hundred thirty = 630 and 630 over 10 means to divide which will equal 630/10=63 and that's the answer 63

The height of a penny dropped from a 64-foot-tall bridge is modeled by the function h=-16t^2+64, where t is the time in seconds and h is the highest of the penny above the lake.Part AComplete the table of values below.
Time(s),t | 0 | 0.5 | 1 | 1.5 | 2 |
-----------------------------------------------------
Height (ft), h | 64 | | | | |
Please tell me how you do the whole things thank yoy

Answers

For a sec, I thought this was AB Calculus with derivatives and second derivatives but it isn't! That's a good thing!

Anyhow, all the problem is asking is to plug in the values of time to find the height.

We see when time is zero, the height is 64 feet. Plug in zero for the "t" variable and you'll get 64 feet.

When the penny has dropped for half a second or 0.5 seconds, we know the "t" variable and plug in that value.

h = -16(.5)^2 + 64.
h = -16(.25) + 64.
h = -4 + 64.
h = 64 feet when the penny has dropped for half a second.

I encouraged student progression when given the knowledge to complete a problem. We know how to complete the rest of the table. Good luck!
