Find the equation of the circle that has a diameter with endpoints located at (-3, 6) and (9, 6).
Answer: [tex](x+3)^2+(y-6)^2 = 36\\\\[/tex]
==========================================================
Explanation:
If you apply the midpoint formula to the given points, you should find the midpoint is (3,6). This point represents the center of the circle. This means (h,k) = (3,6).
The radius is r = 6 because this is the distance from the center to either given endpoint. Either count out the spaces or use subtraction of the x coordinates. This works because the y coordinates are all the same.
Use those h, k and r values to plug them into the equation below
[tex](x-h)^2+(y-k)^2 = r^2\\\\(x-(-3))^2+(y-6)^2 = 6^2\\\\(x+3)^2+(y-6)^2 = 36\\\\[/tex]
which represents the equation of the circle we're after.
The graph is below.
plzz help me i really need it
Answer:
>
Step-by-step explanation:
since we know that w=4 then all we need to do if fill out the equation so we get 3*4^2+1 10*4+8 so then we just need to solve the equation
3*4^2+1 10*4+8
3*16+1 10*4+8
48+1 40+8
49 48
so since we know that 49 is bigger then 48 we have to put > to show that 49 is bigger or greater than 48
I need help trying to solve this or trying to prove if the two ratios equivalent or not. PLEASE HELP!!
Answer:
they are equivalent because when they have the same denominator, they have the same numerator.
Step-by-step explanation:
make the denominators the same by multiplying them together.
84/126 . 84/126
Answer:
They are equivalent.
Step-by-step explanation:
4 14
-- and --
6 21
Calculating the cross product:
4* 21 = 84

Figure ABCDEF is shown. A is located at 5, negative 8. B is located at 11, negative 8. C is located at 11, 0. D is located at 6
Answer:
51.5 unit²Step-by-step explanation:
Add two horizontal segments to divide the figure into three:
Extend ED and add segment from the point F to BC.Now we have two trapezoids and one triangle.
Area of triangle:
A = 1/2*(11 - 6)*(0 - (-3)) = 1/2(5)(3) = 7.5Area of trapezoids:
A = 1/2[(11 - 4 + 11)*(-3 - (-6)) + (11 - 5 + 11)*(-6 - (-8))] = 1/2(18*3 + 17*2) = 44Total area:
7.5 + 44 = 51.5Calculate 0.82 + 0.35 and get the sum of the equation

If you earn both hourly wages and a commission at your job, your gross wages, w, can be calculated with the following equation:
cs + rh = w
where c is your commission rate, s is your total sales in dollars, r is your hourly rate, and h is your hours worked.
Solve for s to rewrite the equation for total sales.
Question 1 options:
s = w + rhc
s = c(w + rh)
s = c(w − rh)
s = w − rhc
Applying the equation, it is found that the solution for s is given by:
[tex]s = \frac{w - rh}{c}[/tex]
The equation we are going to work in this problem is given by:
[tex]cs + rh = w[/tex]
We want to solve for s, hence, we have to isolate s, first placing rh on the other side with the inverse signal(subtraction).
[tex]cs = w - rh[/tex]
Division is the inverse of multiplication, thus, c is multiplying s, it goes to the other side dividing:
[tex]s = \frac{w - rh}{c}[/tex]
Which is the solution for s.

Maximillan is cleaning shrimp. He cleans 4 shrimp every minute. Use time in minutes as the independent quantity, x, and the number of shrimp as the dependent quantity, y.
1. Identify the unit rate of this relationship. Explain what the unit rate means in terms of this situation.
2. Write an equation that demonstrates the number of shrimp cleaned per minute.
3. Is the relationship proportional or non-proportional? Explain how you can determine this using the graph and the equation.
Answer:
1. 1:4
2. y = 4 x X
3. yes
Step-by-step explanation:
1. every 1 minuet he cleans 4 shrimp
2. y is the number of shrimp and x is the time. if every miuet he cleans 4 shrimp, then that means you have to multiply the shrimp by the minuets. for example, if he spends 2 minuets, he cleans 8 shrimp because 2 x 4 = 8.
3. This is a proportional relationship because if you were to put this on a graph, it would be a strait line. for example, if you were to plot x (the time) on a line (this line would go horizontal) and y (shrimp) on the line (this line goes verticle) 1 minuet = 4 shrimp. 2 minuets = 8 shrimp. 3 minuets = 12 shrimp. 4 minuets = 16 shrimp.
i hope this helps. tell me if this is too confusing or if you need more help. have a great day :)
Ryan wants to borrow a DVD from Zac so Ryan walks 12 blocks west to Zac's house, picks up the DVD, and
then walks 12 blocks back to his house, What was the total displacement Ryan traveled?
12 blocks west
24 blocks west
O blocks west
O 6 blocks west
Answer:
12 blocks west
Step-by-step explanation:
Okay so he walked 12 blocks west to Zac's house and then walked another 12 blocks back this means that he had to walk 12 blocks west to get to Zac's house
P.S. Sorry if it is wrong
Answer:
0 blocks west
Step-by-step explanation:
If you end at the same place you started just like on a racetrack one full lap. Walking 12 blocks west then 12 blocks east back to the house displacement is 0 because you are back where you started from.
