radius = ?equation = x^2 + (y-10)^2 = 16Equation of a CircleThe equation of a circle is given as
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Let's substitute our given variables here and solve
[tex](x-h)^2 + (y - k)^2 = r^2\\(x-0)^2 + (y-10)^2 = 4^2[/tex]
All we need to do here try to write the equation in the standard form which is given above and then pick the value of radius (r) from there

The model represents an inequality. What is the solution set for the inequality?
Answers
Given:
The figure of an algebraic tiles model of an inequality.
To find:
The inequality for the given model.
Solution:
On the left hand side of the inequality sign in the model we have 8 tiles of x and 12 tiles of 1. So,
[tex]LHS=8(x)+12(1)[/tex]
[tex]LHS=8x+12[/tex]
On the right hand side of the inequality sign in the model we have 12 tiles of -1. So,
[tex]RHS=12(-1)[/tex]
[tex]RHS=-12[/tex]
Now, the inequality for the given model is:
[tex]8x+12\geq -12[/tex]
Therefore, the required inequality for the given model is [tex]8x+12\geq -12[/tex].

A piano instructor charges students a one-time fee for sheet music and an hourly rate for lessons. The graph below shows the total cost for a student who has taken x lessons.
Answers
Two points passing through the line are (2, 80) and (4, 140)
Let the one time fee = $b
Hourly charges for the lessons = $x
Equation of the line will be,
y = mx + b
Slope of the line 'm' =
m =
m =
m = 30
y = 30x + b
For point (2, 80),
80 = 30(2) + b
b = 80 - 60
b = 20
Therefore, one time fee charged by the instructor = $20
Since instructor put a coupon to waive off the one time fee, value of the coupon will be = $20

how do we compare the absolute values of -99 and 1? *
Answers
Answer:
The first one
Step-by-step explanation:
The absolute value of a negative number is the same number but positive if that makes sense. ( ex absolute value of -5 is 5 )
The absolute value of a positive number is literally that number ( ex. absolute value of 6 is 6 )
Thus, the absolute value of 1 is 1 and the absolute value of -99 is 99
99 is greater than 1 which means that the absolute value of -99 is greater than the absolute value of 1
Thus, the answer is the first one

How can you tell from the equation of a rational function if the function has a hole in the graph ( a removable discontinuity) at x, rather than a vertical asymptote? Give an example
Answers
Consider that,
x^2+4x+4 = (x+2)(x+2)
x^2+7x+10 = (x+2)(x+5)
Dividing those expressions leads to
(x^2+4x+4)/(x^2+7x+10) = (x+2)/(x+5)
The intermediate step that happened is that we have (x+2)(x+2) all over (x+2)(x+5), then we have a pair of (x+2) terms cancel as the diagram indicates (see below). This is where the removable discontinuity happens. Specifically when x = -2. Plugging x = -2 into (x+2)/(x+5) produces an output, but it doesn't do the same for the original ratio of quadratics. So we must remove x = -2 from the domain.

What is the missing length?
Answers
Answer:
16
Step-by-step explanation:
The area of a triangle is
A =1/2 bh where b is the base length and h is the height
Substitute the values in
69.6 = 1/2 ( 8.7) * p
69.6 = 4.35p
Divide each side by 4.35
69.6/4.35 = p
16 = p
The formula for the area of a triangle is: A = 1/2 * base * height.
Using this formula, let's plug in what we know.
69.6 = 1/2 * 8.7 * height
Next, we'll go ahead and get rid of that 1/2 by multiplying everything by its reciprocal, 2.
139.2 = 8.7 * height
Then, all that's left is to divide both sides by 8.7.
Height = 16 yards
Hope this helps!! :)

Ms. Madero sells tables. She charges $26 per square foot of the tabletop and charges a fixed fee of $75. Which equation could be used to find the area
(x), in square feet, of the tabletop of a table that Ms. Madero sells for $244?
O 26x + 75 = 244
O 26x = 75 +244
O 75x + 26 = 244
O 75x = 26 +244
Answers
Step by step explanation:
It is 26 per square foot, the square foot of the table tops vary and people may choose a table with a smaller/larger table tops here the square foot of the table tops is unknown so we verify it as the x variable. 26 per x so 26x
A fixed cost is always added to the variable cost, 26x “variable cost” + 75 fixed cost = 244 final cost
We can find how many square foot was her table top by rearranging the equation.

26x+75=244
