Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

Bula drives to work and back every day. One way, the trip is fifty miles.

The number of miles that she drives in five days will be given as,

50 = D / 5

D = 50 x 5

The function y= √(x+11) + 5 has Domain x≥-11 .

The Domain of the function is defined as the set of all possible values , that can be input in the function .

In the question;

it is given that

Option(a)

the function is ,

y = √(x + 11) + 5

the square root is defined only for x≥0,

So, we have x+11≥0

subtracting 11 from both the side , we get

x ≥ -11

hence Domain is x≥-11 .

Option(b)

the function is ,

y = √(x - 11) + 5

we have x-11≥0

Adding 11 to both the side , we get

x ≥ 11

hence Domain is x ≥ 11 .

Option(c)

the function is ,

y = √(x + 5) - 11

we have x+5≥0

subtracting 5 from both the side , we get

x ≥ -15

hence Domain is x ≥ -5 .

Option(d)

the function is ,

y = √(x + 5) + 11

we have x+5≥0

subtracting 5 from both the side , we get

x ≥ -15

hence Domain is x ≥ -5 .

From above we can see that only option(a) has Domain as x ≥ -11.

Therefore , the function y= √(x+11) + 5 has Domain x≥-11 , option(a) is correct .

The given question is incomplete , the complete question is

Which function has the domain x ≥ -11?

(a) y = √(x + 11) + 5

(b) y = √(x - 11) + 5

(c) y = √(x + 5) - 11

Answer: 0.8

Step-by-step explanation:

The formula to find area of a parallelogram is A = bh. This means that area = base x height. You can manipulate this formula to what height equals instead of the area. To do that, you can divide b on both sides. This would make the equation h = A/b.

Now that you know how to find what height equals, first find the base of the parallelogram. To find b, multiply 6 x 5. 6 x 5 = 30. This means that your base is 30.

Take the information given to you in the problem about the area. The area is given to you. We know that the area is 24 squared units. Remember what the equation to find height is. It's h = A/b. Substitute the variables for your numbers. h = 24/30.

24/30 = 0.8.

This means that your height is 0.8. This would be 8/10 in fraction form, but you can simplify it further to 4/5.

Hope it helps. Good luck!

The line AB joining the points A and B on the plane M lies in plane M.

Say there are two points A and B which lies on the plane M.  

Through any two points, there is only one line. Then there is exactly one line joining the two points A and B which is the line AB

Since both the points lies on the plane M, the line joining them should also lie on the plane M.

The postulate which verifies this is:

If two points lie on a plane, then the line joining the points also lies on the same plane.

Using the expression 5x/12 = 20, the amount that A originally had was $48.

We have,

Let x be the amount of money that A originally had.

Then, A gave away 1/2 x 1/3 = 1/6 of the amount, which is equal to x/6.

The amount received by B is 1/2 of the remaining amount,

which is (x - x/6)/2 = 5x/12.

We know that 5x/12 = 20,

Solving for x.

5x/12 = 20

5x = 240

x = 48

Answer:

Step-by-step explanation:

The mean absolute deviation is 0.75

To calculate the mean absolute deviation (M.A.D.), you need to find the average of the absolute differences between each data point and the mean of the data set

From the information given, we have that the data set is;

8 9 9 7 8 6 9 8

Let's calculate the mean, we get;

Mean = (8 + 9 + 9 + 7 + 8 + 6 + 9 + 8) / 8

Mean = 64 / 8

Divide the values

Mean = 8

Let's determine the absolute difference, we get;

Absolute differences=

|8 - 8| = 0

|9 - 8| = 1

|9 - 8| = 1

|7 - 8| = 1

|8 - 8| = 0

|6 - 8| = 2

|9 - 8| = 1

|8 - 8| = 0

Find the mean of the absolute differences:

Average of absolute differences = (0 + 1 + 1 + 1 + 0 + 2 + 1 + 0) / 8

Absolute difference = 6 / 8 = 0.75

The area of the square A is 19.98 square feet

From the question, we have the following parameters that can be used in our computation:

Two squares constructed on the sides of a rectangle.

Let the side lengths of square C be x

Let the side lengths of rectangle B be x and y

So, we have

x² = 5

xy = 10

Solving for x and y, we have

x = 2.24 and y = 4.47

The area of square A is

Area = y²

So, we have

Area = 4.47²

Evaluate

Area = 19.98

Answer: Half of them are even and half of them are odd.

Step-by-step explanation:

The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.

The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.

Therefore, out of the given numbers, half of them are even and half of them are odd.

It is very simple

Any number's absolute value should be positive

Let's say absolute value of 3 - >answer is 3

But absolute value of - 3 - > is also 3

Hope you understood it.

Answer:

In math students think that the function just removes negative signs, and actually that is basically what happens...

BUT !!! the definition that you want is that absolute value is a measure of how far (distance) you are from ZERO.... and note that distances are not negative...

If you run out of gas one mile in front of behind a gas station, you have to travel "one mile" you don't walk "negative one mile"...

forward one mile or backward one mile are both "one mile" just in different directions

Step-by-step explanation:

We are asked to decide if the expression:

x^2 + y^2 = 1 represents a function.

We recall that in order to have a function, we need for a given value of x to have a SINGLE value of y associated with it.

So in this case, when x is 0 for example, we have the following:

0^2 + y^2 = 1

then y^2 = 1

and we realize that there are TWO values of y whose square form gives 1 (one is 1 and the other -1) Therefore, this relationship is NOT a function, since for example when x = 0 there are TWO values of y to which that x is associated (y = 1 and y = -1).

So please select that this is NOT a function for your answer.
