Write the standard form of the equation of the circle that passes through the given point and whose center is at the origin.
(-6,0)
The equation of the circle that passes through the point (-6 , 0) and has a center located at the origin is x^2 + y^2 = 36.
Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-6 , 0).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(-6 - 0)^2 + (0 - 0)^2
radius= √36
radius = 6
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (0 , 0)
r = 6
(x - 0)^2 + (y - 0)^2 = 6^2

Using it's concept, the average rate of change of the function in the intervals is given by:
a. 1.
b. -5/3.
c. -1.
d. 4.
e. -3.
f. 0.
What is the average rate of change of a function?
The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
For item a, we have that:
f(-3) = 0.f(-2) = 1.Hence the rate is:
r = (1 - 0)/(-2 - (-3)) = 1.
For item b, we have that:
f(-2) = 1.f(1) = -4.Hence the rate is:
r = (-4 - 1)/(1 - (-2)) = -5/3.
For item c, we have that:
f(0) = -3.f(1) = -4.Hence the rate is:
r = (-4 - (-3))/(1 - 0) = -1.
For item d, we have that:
f(1) = -4.f(2) = 0Hence the rate is:
r = (-0 - (-4))/(2 - 1) = 4.
For item e, we have that:
f(-1) = 0.f(0) = -3.Hence the rate is:
r = (-3 - 0)/(0 - (-1)) = -3.
For item f, we have that:
f(-1) = 0.f(2) = 0.Hence the rate is:
r = (0 - 0)/(2 - (-1)) = 0.

Consider the inequality 38 ≤ bx + 8
What value of b will result in the solution x ≤ - 6?
For the value of (b = -5) the result of the solution is x ≤ - 6.
What is termed as the inequality?The term inequality refers to a mathematical equation wherein the sides are not equal. An inequality equates any two values and shows that one is less, greater, or equal to the value on either side of the equation.
Rule 1: When inequalities are connected, they can be crossed. As a result, if an is greater than b and b is greater than c, a will be greater than c as well.Rule 2: When you swap the values, the sign as well reverses.Rule 3: An inequality can be either > or, but not both at the same time.Rule 4: Reversing the sign by multiplying both sides of the inequality by the a negative sign.Consider the given expression;
38 ≤ bx + 8
Simplify the equation;
38 - 8 ≤ bx
30 ≤ bx
Multiply both side with negative sign; by the rule four, the sign of inequality will also change.
- 30 ≥ -bx
or -bx ≤ - 30
For converting the value to the expression x ≤ - 6; the value which should be divide the 30 is 5.
Thus,
-(-5)x ≤ - 30
Thus, the value of b is found as (b = -5).

The probability, expressed as a percentage rounded to a nearest tenth, that Victoro chooses a green jelly then a red one is 0.1.
What is defined as the combinations in a probability?A combination is a preference of all or part of a group of objects, regardless of their order of selection.
You can choose the items in just about any order in combinations. Permutations and combinations are often confused.
Now, as per the given question;
The total number of red jelly beans in a bag is 7.
The total number of yellow jelly beans in a bag is 11.
The total number of green jelly beans in a bag is 13.
Thus, the total number of jelly beans in a bag is;
7 + 11 + 13 = 31.
First, Victoro picks the green one;
Thus, the probability of picking a green jelly out of total 13 green jellys is;
¹³C₁/ ³¹C₁ = 13/31
Now, as the second jelly picked by Victoro is red which is without replacement.
Thus, the probability for getting a red jelly out of total 30 left jellys is;
⁷C₁/ ³⁰C₁ = 7/30
Therefore, the total probability that Victoro picks a green one and then a red one is ;
= 13/31×7/30

A medical insurance policy requires Ana to pay the first $100 of her hospital expense. The insurance company will then pay 90% of the remaining expense. Ana is expecting a short surgical stay in the hospital, for which she estimates the total bill to be about $4,700. How much (in $) of the total bill will Ana owe
The total bill that Ana would pay is $560.
What is the total bill Ana would pay?The total bill that Ana owes is the sum of the first $100 and 10% of the remaining bill since the insurance company would pay 90% of the bill.
The mathematical operation that would be used to determine the total bills are addition, multiplication and subtraction. Addition is the process of determining the sum of two or more numbers. Subtraction is the process of calculating the difference between two or more numbers. Multiplication is the process of determining the product of two or more numbers.
Total bill = first $100 + 90%(total bill - $100)
$100 + 10%($4,700 - $100)
$100 + 10% x 4,600

Evaluate the indefinite integral by using the given substitution to reduce the integral to standard form.
The indefinite integral, [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{-1}{9} cos(9x) + C[/tex]
We have to find the indefinite integral,
[tex]\int {sin(9x)} \, dx[/tex]
using the substitution 9x = u.
So we need to change the variable of integration from x to u using this substitution.
9x = u ⇒ 9 dx = du
So [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{1}{9} \int{sin(u) \ du[/tex]
= 1/9 (- cos(u)) + C, [ Since integral of sin(u) = -cos(u) ]
where C is the integration constant which is often put when evaluating indefinite integrals.
Now replacing u with x to get the final answer,
1/9 (- cos(u)) + C = -1/9 cos(9x) + C
Therefore, [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{-1}{9} cos(9x) + C[/tex]
