Hello!

The equation for a circle is

(h, k) is the center

You find what numbers make the equation

Since x is not subtracted from anything h = 0

Since k is positive k is the negative of that number

The equation is

The center is (0, -9)

Hope this helps!

Scientists discovered a large star 400,000 light years from Earth.A light-year is about 5,880,000,000,000 miles.What is the distance of the large star from Earth in scientific notation?
Solution 1
So if you want to find the distance, you would take 400,000x5,880,000,000,000=
2.35200000E+18. So your answer would be 2.35200000E+18 in scientific notation it would be 2.35200000x10^18. I hope this helps!

Question
The heights of the trees for sale at two nurseries are shown below. Heights of trees at Yard Works in feet : 7, 9, 7, 12, 5 Heights of trees at The Grow Station in feet : 9, 11, 6, 12, 7 Which statements are true regarding the measures of center and variability of these data sets? Check all that apply. The mean of tree heights at Yard Works is 7 feet. The mean of tree heights at Yard Works is 8 feet. The mean of tree heights at The Grow Station is 9 feet. The mean of tree heights at The Grow Station is 10 feet. The mean absolute deviations of the tree heights at both yards is 2. The mean absolute deviations of the tree heights at both yards is 3. Mark this and return Save and Exit
Solution 1

The mean of tree heights at Yard Works is 8 feet and at Grow Station is 9 feet.The mean absolute deviation of the tree heights at both yards is 2.

Step-by-step explanation:

1). Height of the trees at Yard Works are = 7,9,7,12,5 feet

So mean height of the trees = (7+9+7+12+5)÷5

= 40÷5 =8 feet

Standard deviation of the trees at Yard works = ∑(║(height of the tree-mean height of the tree))║/(number of trees)

(height of the tree-mean height of the tree)= ║(7-8)║+║(9-8)║+║(7-8)║+║(12-8)║+║(5-8)║ = (1)+1+(1)+4+(3)= 10

Therefore standard deviation = (10)/(5) =2

2). In the same way mean height of the trees at Grow Station=(9+11+6+12+7)/5= 45/5 = 9

Now we will calculate the mean deviation of the tress at Grow Station

= ∑║(height of the tree-mean height of the tree)║/(number of trees)

= ║(9-9)║+║(11-9)║+║(6-9)║+║(12-9)║+║(7-9)║/(5)

= (0+2+3+3+2)/5

= 10/5 =2

Therefore The mean of tree heights at Yard Works is 8 feet and at Grow Station is 9 feet.The mean absolute deviation of the tree heights at both yards is 2.

Solution 1

To solve this problem you must apply the proccedure shown below:

1. You have that the arc lengt is 6 and the area os 78,5 cm^2. Therefore, you must apply the following formula:

2. The value of the radius is:

A=2πr²
r=√A/2π
r=√25
r=5

3. When you clear θ , you obtain:

For either linear regression or multiple regression, the standard error of estimate can be computed as ____.​ a. ​the square root of msresidual b. ​the square root of msregression c. ​msresidual/(n – 2) d. ​msregression/(n – 2)
Solution 1
The standard error of the estimate is a measure of the accuracy of predictions.

It is given by the square root of the mean square residual.

Therefore, f
or either linear regression or multiple regression, the standard error of estimate can be computed as ​the square root of msresidual.

Question Conrad and jill have a taxable income of 63,670. they discovered that they are able to receive$1,500 tax credit for purchasing an energy efficient furnace. How will this tax credit affect their taxes? A) the tax credit will increase their taxable income by $1,500 B) the tax credit will reduce their taxable income by$1,500 C) the tax credit is added to the tax owed, not the taxable income D) the tax credit is subtracted from the tax owed, not taxable income
Solution 1
The answer is letter D. The tax credit will be subtracted from the tax owed, not taxable income. This is because a tax credit is something that will be deducted or offset to your liability and that is the tax you owed based on your own taxable income.
