Answer:

(-6, 6).

Step-by-step explanation:

The x-coordinate increases by 2 units and the y-coordinate by 9 units:

That is ( - 8 + 2, -3 + 9)

= (-6, 6).

How can you find a ratio in a bar graph

kap26 [50]

Divine the total number of the entire chart by the number of a single line or bar to give you the ratio in a bar or line chart. For example, if a bar or line represented 5 in a chart with a total of 30, you would divide 30 by 5. This would give you a result of 6. Therefore, the ratio would be 6:1.

What is -3/4 + 2 3/4

Fittoniya [83]

Answer:

Step-by-step explanation:

ok so let's start

were starting off with -3/4 and were adding 2 3/4 to that and it's equal to 2 3/4 subtract 3/4

-3/4 + 2 3/4 = 2 3/4 - 3/4

2 3/4 - 3/4 = 2

-3/4 + 2 3/4 = 2

it's 2 my dude or girl i don't know

9 m 3 m 3 m What is the area, in square meters, of the shaded region in the diagram?

NeTakaya

Answer:

Notice that the side length of the square is 38 m.

area of square = (side length)2 = (38 m)2 = 1444 m2

Notice that the diameter of the circle is 38 m .

And its radius = diameter / 2 = 38m / 2 = 19 m

area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2

So......

area of shaded region = area of square - area of circle

area of shaded region ≈ 1444 m2 - 1133.54 m2

area of shaded region ≈ 310.46 m2

Step-by-step explanation:

Notice that the side length of the square is 38 m.

area of square = (side length)2 = (38 m)2 = 1444 m2

Notice that the diameter of the circle is 38 m .

And its radius = diameter / 2 = 38m / 2 = 19 m

area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2

So......

area of shaded region = area of square - area of circle

area of shaded region ≈ 1444 m2 - 1133.54 m2

area of shaded region ≈ 310.46 m2

A circle is centered at the point (5,-4) and passes through (-3,2). The equation of this circle is (x+___)²+(y+___)²=____.

JulsSmile [24]

The equation of a circle is:
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the location of the center and r is the radius. So we need to find h, k, and r. The center is given as (5,-4) so h = 5 and k = -4:
(x-5)^2 + (y-(-4))^2 = r^2
(x-5)^2 + (y+4)^2 = r^2
So we need to find r. Use the distance formula to find the distance between (5,-4) and (-3,2):
r = [(5-(-3))^2+((-4)-2)^2]^1/2
r = [8^2 + (-6)^2]^1/2
r = [64 + 36]^1/2
r = 100^1/2
r= 10
The final equation is:
(x-5)^2 + (y+4)^2 = 10^2
