Circular equations are often organized in the following form:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
[tex](h,k)[/tex] is where the circle is centered[tex]r[/tex] is the radiusTo find the equation of a circle given its center and a point:
Plug the center into the general equation as (h,k)Plug the given point into the general equation as (x,y)Solve for r²Plug (h,k) and r back into the original equationSolving the QuestionWe're given:
Center: (-7,7)Point: (-2,-5)Plug the center into the general equation:
[tex](x-(-7))^2+(y-7)^2=r^2\\(x+7)^2+(y-7)^2=r^2[/tex]
Plug in the given point (-2,-5) and find r²:
[tex]((-2)+7)^2+((-5)-7)^2=r^2\\(5)^2+(-12)^2=r^2\\25+144=r^2\\r^2=169[/tex]
Plug the center and radius back into the original equation:
[tex](x-h)^2+(y-k)^2=169\\(x+7)^2+(y-7)^2=169[/tex]
Answer[tex](x+7)^2+(y-7)^2=169[/tex]

Answer:
100 cm square?
Step-by-step explanation:
1 meter square = 100 cm square
Answer:
10,000 cm²
Step-by-step explanation:
m² to cm² conversion
1 m x 1 m = 1 m²But we know : [1 m = 100 cm]100 cm x 100 cm = 10,000 cm²Therefore, 1 m² = 10,000 cm²So, the surface area of the prism in cm² is 10,000 cm²

The sum of all but one interior angle of an octagon is 776°. The measure of the final interior angle is ___ degrees.
the sum of all interior angles in a polygon, regular or not is
180( n - 2), n = number of sidesnow, this is an octagon, with 8 sides, so it has a total of interior angles of 180( 8 - 2) or 180(6) = 1080.
we know the sum of all BUT one is 776°, so the last one must be 1080° - 776° = 304°.

Step-by-step explanation:
The area painted would be 3672 sq in.
A scale model of a ramp is a right triangular prism as given in this figure. In the actual ramp, the triangular base has a height of 0.5 yards.
What is the surface area of the actual ramp, including the underside?
Enter your answer as a decimal in the box.
The answer is 7.2 I just didnt see anyone ask this
The surface area of the figure is 720 square inches
How to calculate the surface area of a ramp?The surface area of a figure is the sum of all the area of its faces.
For the given diagram, it consists of 2 triangular faces and 3 rectangular faces
Surface area= (5 * 24) + 2(13*12) + 24 * 12
Surfacee area = 120 + 312 + 288
Surface area = 720 square inches
Hence the surface area of the figure is 720 square inches

Which pairs of angles are supplementary?
1 and 6
5 and 7
5 and 8
2 and 3
Answer:
1 and 6
5 and 7
Step-by-step explanation:
Supplementary angles are 180 degrees and so is a linear pair
1 and 6 add up to 180 degrees meaning they are supplementary. Angle 1 and angle 2 are a linear pair so 180-120=60 which is the degree of angle 1, angle 2 corresponds to angle 6, so angle 1 + angle 6 would equal 180 degrees. (120+60)
5 and 7 are a linear pair which automatically makes them supplementary
The others are vertical angles which don't add up to 180. (120+120=240)(60+60=120)

Find the y-intercept and the slope of the line.
Y=-4x-3
Slope:-
-4
y-intercept:-
(0,-3)
Solution:-The equation of this line is written in Slope-Intercept Form, which looks like so:-y=mx+bIn this formula, m stands for the slope of the line, and b stands for the y-intercept.Please remember that the slope is the line's rise (the amount of units we move up, or "rise" divided by its run (the amount of units we move left or right, and the y-intercept is the point where the line intersects the y-axis. (0, b)Also, please notice that m is the coefficient of x, and b is the constant.Therefore, the slope of the line is equivalent to -4, and the y-intercept is (0, -3).Hope it helps.
Do comment if you have any query.
Answer:
Slope: 4; y-intercept: -3
Explanation:
To find the slope of the line, we will look at the number in front of x.
That number is -4. Hence, the slope is -4
Now, the y-intercept is the constant.
The constant is -3.
Hence, the y-intercept is -3.
