Answer:

  c.  D = {x | x ≥ -3}, R = {y | y ≥ 0}

Step-by-step explanation:

The domain is the horizontal extent of the graph. The range is its vertical extent.

__

We observe that point (-3, 0) is a point on the graph, so x=-3 is included in the domain, and y=0 is included in the range. The only answer choice that has the "or equal to" case included for both x and y is ...

  D = {x | x ≥ -3}, R = {y | y ≥ 0}

The figure is an illustration of the relationship between the angles in a circle and arc

From the figure, the arc PQ is subtended by the angle PAQ.

This means that:

PQ = ∠PAQ

Given that ∠PAQ = 130, it means that:

Arc PQ = 130

The measure of PSQ is then calculated using:

∠PSQ = 0.5 * Arc PQ ----- inscribed angle is half a subtended angle.

This gives

∠PSQ = 0.5 * 130

∠PSQ = 65

Hence, the measure of ∠PSQ is 65 degrees

A semicircle measures 180 degrees.

This means that:

QR + PQ = 180

So, we have:

QR = 180 - PQ

Substitute 130 for PQ

QR = 180 - 130

QR = 50

Hence, the measure of QR is 50 degrees

The measure of arc RS is then calculated using:

∠RPS = 0.5 * Arc RS ----- inscribed angle is half a subtended angle.

Where ∠RPS = 35

So, we have:

35 = 0.5 * Arc RS

Multiply both sides by 2

Arc RS = 70

Hence, the measure of RS is 70 degrees

In (a), we have:

∠PSQ = 65

This means that:

∠PSQ = ∠PSB = 65

So, we have:

∠PSB = 65

Next, calculate SBP using:

∠SBP + ∠BPS + ∠PSB = 180 ---- sum of angles in a triangle.

So, we have:

∠SBP + 35 + 65 = 180

∠SBP + 100 = 180

This gives

∠SBP = 80

The measure of AQS is then calculated using:

AQS = AQB = 180 - (180 - SBP) - (180 - PAQ)

This gives

AQS = 180 - (180 - 80) - (180 - 130)

Evaluate

AQS = 30

Hence, the measure of AQS is 30 degrees

A semicircle measures 180 degrees.

This means that:

PS + RS = 180

This gives

PS = 180 - RS

Where RS = 70

So, we have:

PS = 180 - 70

Evaluate

PS = 110

Hence, the measure of arc PS is 110 degrees

Answer:

50 cents ($0.50)

Step-by-step explanation:

We need to find the price for one orange. To get one orange, you have to divide 6 by 6. Anything you do to one side of the equation must be done to the other side. You have to divide 3 by 6. If you do this, you get .5, or 1/2. In money, that translates to 50 cents.

Hope this helps!

Step-by-step explanation:

the price of one orange is indeed 3/6 = 1/2 = $0.50.

the equation residential the price for any number of oranges contains then a variable, say x, to stand for the number of purchased oranges :

p(x) = 0.5x

meaning that the price of x oranges is 0.5×x.

Becuase the two numbers have the same variable, you can add them together. The exponents do not change.

Answer:

5t +9t is equivalent to 14t

5t -9v is not equivalent to 9v-5t

5(9t-5) is not equivalent to 45t-5 because 5(9t-5) is 45t-25

Answer:

Mean - 63

Median - 57

The Mean affects the outlier the most.

Step-by-step explanation:

Mean is where u add all the numbers up and then divide them by how many are there. So  50 + 50 + 52 + 57 + 66 + 67 + 99 = 441. There are 7 numbers so 441/7 which equals 63. So mean is 63.

For median u order them least to greatest which is 50,50,52,57,66,67,99. The median is the middle number of this set which is 57.

Outlier is the first number which is 50. So the mean is the answer for which measure does the outlier affect the most bc 63 is bigger than 57 the median. So basically which is a more difference.

Answer:

No Change

Step-by-step explanation:

If you add all of the numbers, you get 32.  When you divide it by how many numbers there were, you get 4.  When you add 4 to 32, you get 36 and since you added one more number, you need to divide 36 by 9, which still makes 4.

[tex]\blue{\textsf{\textbf{\underline{\underline{Question:-}}}}[/tex]

          What is the equation of the line in slope intercept form if its slope is 8 and its y-intercept is -3?

[tex]\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}[/tex]

y=8x-3

[tex]\blue{\textsf{\textbf{\underline{\underline{How to solve:-}}}}[/tex]

Slope Intercept form, as the name implies, has slope & intercept in its equation.

It looks like y=mx+b, where "m" is the slope and "b" is the y-intercept.

To determine the equation of the line, we need to write the value of m, which in this case is 8, in lieu of m:-

y=8x+b

Same with the y-intercept:-

[tex]\tt{y=8x+(-3)}[/tex]

Which simplifies to

Answer:

f(x) ≈ −2.42x3 + 15.89x2 − 7.55x + 12

Step-by-step explanation:

Notice that the year data are evenly spaced. Check the first differences between the total number or units to see if the data set is linear.

First Differences

41 − 18 = 23

67 − 41 = 26

82 − 67 = 15

69 − 82 = −13

17 − 69 = −52

Because the first differences are not constant, a linear model is not the best model of the data. Check the second differences to see if the data set can be modeled by a quadratic function.

Second Differences

26 − 23 = 3

15 − 26 = −11

−13 − 15 = −28

−52 − (−13) = −39

Because the second differences of the independent variable are not constant, a quadratic model is not the best model of the data. Check the third differences to see if the data set can be modeled by a cubic function.

Third Differences

−11 − 3 = −14

−28 − (−11) = −17

−39 − (−28) = −11

The third differences are approximately the same so we will use a cubic function to represent the data.

Enter the data into a calculator. Plot the data and find the cubic regression equation that best models the data.

Answer:

$33.25

Step-by-step explanation:

Taking Eric's hours as a ratio to the total hours :

Multiply the ratio into the amount paid :

Eric's share of the money is $33.25

Answer:

$33.25

Step-by-step explanation:

The combined, total number of hours they worked is

3.5 hours + 2 hours = 5.5 hours

The total pay is $52.25

The pay rate is $52.25/(5.5 hours) = $9.50/hour

Eric worked 3.5 hours.

Pay = 3.5 hours × $9.50/hour = $33.25

Answer:

1.) The power in repeated multiplication form is: -8 × -8

     -----> Since -8 is raised to the power of 2, it means that there should be two -8's being multiplied together.

2.) The value of the power is: 64

   -----> Remember, a negative number times a negative number is equal to a positive number. Therefore, -8 × -8 = 64.

The solution to the system of linear equation x + y = 4 and x - y = 6 is (5, -1).

x + y = 4

x - y = 6

Therefore, let's add the equations.

2x = 10

divide both sides by 2

x = 10 / 2

x = 5

Let's find the value of y

Therefore,

x + y = 4

5 + y = 4

y = 4 - 5

y = - 1

Therefore, the solution of the system of equation is (5, -1)
