How to identify the center and radius of a circle?
A general circle equation centered at the point (a, b), with a radius of R, is written as:
(x - a)^2 + (y - b)^2 = R^2
Then for the given equations we have:
1) (y-6)^2 + (x - 1)^2 = 9
So the center is at (1, 6) and the radius is 3.
2) (x-2)^2 + (y + 3)^2 = 36 = 6^2
So the center is at (2, -3) and the radius is 6.
3) (x + 4)^2 +(y-5)^2 = 25 = 5^2
So the center is at (-4, 5) and the radius is 5.
The graphs of the 3 circles can be seen below. Green is the first circle, blue is the second circle, and red is the last circle.

Using the distributive property to factorize the equation 3x² + 24x = 0, you get 3x(x + 8) = 0 and the solution of the equation is x = -8
How to factorize the expression?The expression is given as:
3x² + 24x = 0
Factor out 3x
3x(x + 8) = 0
Divide both sides by 3x
x + 8 = 0
Subtract 8 from both sides
x = -8
Hence, the solution of the equation is x = -8

What is the solution to the linear equation graph?From the given linear equation graph, we see that the linear equation that is graphed is given by;
y = ¹/₄x - 1
Now, the solution to the given equation will be the value of x that corresponds with the value of y when traced on the graph.
Let us access (4, 0)
At x = 4, we have;
y = ¹/₄(4) - 1
y = 0
Thus, (4, 0) is a solution of the graph.

Answers
You cannot combine two terms into one;
2(-20) + 3(-25) doesn’t equal (3 + 2)(-20 + -25)
Evaluate each term separately:
(-40) + (-75) = -115
The way it was combined would be: 5 x (-45) = -225.
A difference of
-225 - (-115) = -110
The same applies to the last 2 terms.
You have to evaluate each term separately.
(-40) + (-75) + (100) + (200) = 300 - 115 = 185
Thus 185 is the correct answer.

The following two-way table represents data from a survey asking students whether they have visited alaska, hawaii, or both. a 4-column table with 3 rows. the first column has no label with entries hawaii, not hawaii, total. the second column is labeled alaska with entries 6, 8, 14. the third column is labeled not alaska with entries 15, 21, 36. the fourth column is labeled total with entries 21, 29, 50. what is the relative frequency for students who have been to alaska? what is the relative frequency for students who have been to hawaii but not alaska? what is the relative frequency for students who have not been to alaska or hawaii?
Answers
Relative frequency is frequency relative to some quantity, usually the marginal or total frequency. The needed relative frequencies are: 14/50, 15/50, and 44/50 respectively.
How to find the relative frequency?Relative frequency is the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency).
The two way table given is:
Alaska Not Alaska Total
Hawaiii 6 15 21
Not Hawaii 8 21 29
Total 14 36 50
Calculating the needed relative frequencies one by one:
Case 1: The relative frequency for students who have been to Alaska
Total students who went to Alaska= 14Total number of students in survey = 50Thus, the relative frequency for students who have been to Alaska (relative to total count) is 14/50
Case 2: The relative frequency for students who have been to Hawaii but not Alaska
Total students who went to Hawaii but not Alaska= 15Total number of students in survey = 50Thus, the relative frequency for students who have been to Alaska (relative to total count) is 15/50
Case 3: The relative frequency for students who have not been to Alaska or Hawaii
Total students who haven't been to Alaska or Hawaii = total students's count - those who have been to both Hawaii and Alaska = 50 - 6 = 44Total number of students in survey = 50Thus, the relative frequency for students who have been to Alaska (relative to total count) is 44/50
Thus, the needed relative frequencies are: 14/50, 15/50, and 44/50 respectively.

Use the drop down-menus to complete the sentences. when parallel light rays exit a concave lens, they . when parallel light rays exit a convex lens, they .
Answers
Answer:
When parallel light rays exit a concave lens, they
✔ diverge
.
When parallel light rays exit a convex lens, they
✔ converge
.
Step-by-step explanation:
The requried, parallel light rays diverge when passing through a concave lens, and converge when passing through a convex lens.
What is reformation?Refraction is the bending of light as it passes from one medium to another medium of different optical densities, such as from air to water or from air to a glass lens.
When parallel light rays exit a concave lens, they diverge as the concave lens is thinner at the center and thicker at the edges. This shape causes the light rays to bend away from the optical axis and spread apart from each other, resulting in a virtual image that is smaller than the object.
On the other hand, when parallel light rays exit a convex lens, they converge towards a focal point as the lens is thicker at the center and thinner at the edges. This shape causes the light rays to bend towards the optical axis and meet at a focal point, resulting in a real image that is inverted and can be larger or smaller than the object depending on the distance of the object from the lens.
Therefore, the behavior of parallel light rays upon exiting concave and convex lenses is quite different due to their distinct shapes and curvatures, resulting in opposite effects on the direction of light rays and the formation of images.

Which graph represents f(x)=4sin(2πx)?
Answers
The function f(x)=4sin(2πx) is a sinusoidal function
The graph of the function f(x)=4sin(2πx) is graph (c)
How to determine the graph of the function f(x)=4sin(2πx)?The parent function of a sine function is
f(x) = sin(x)
The function f(x)=4sin(2πx) implies that the parent function f(x) = sin(x) has been horizontally and vertically stretched
So, the graph of the function f(x)=4sin(2πx) would have a higher amplitude and shorter period than its parent function
Hence, the graph of the function f(x)=4sin(2πx) is graph (c)
