1.3 meters because the radius is half of the diameter, which is 2.6
The answer to this problem is -5x=8
Remember that the general formula for a circle is <span>
(x – h)</span>² + (y – k)² = r²<span>, where (h,k) is the coordinate of the center.
We already know that (h,k) = (5,-4), since we know the center's coordinates. We need to find r, the radius, using the distance between the center and the point (-3,2).
To do this, we can either use the distance formula, or plug in the points in our circle equation and solve for r.
Let's do the second one, plugging in and solving for r.
We can use the point (-3,2) for (x,y):
</span>(x – h)² + (y – k)² = r²
(-3 - 5)² + (2 - -4)² = r²
(-8)² +(6)² = r²
64 + 36 = r²
100 = r²
r = 10
We know that r=10, and that r² = 100
Using h, k, and r, we can now solve for the equation of the circle in standard form.
The equation of the circle is:
(x – 5)² + (y + 4)² = 100
Answer:
beam, vault, uneven bars, floor
Step-by-step explanation:
<u><em>The complete question is</em></u>
A group of gymnasts were asked to name their favorite piece of equipment. 0.33 of the gymnasts chose the vault, 4/9 chose the beam, 0.08 chose the floor exercise, and 1/7 chose the uneven parallel bars. List their choices in order of preference from greatest to least.
step 1
Convert 4/9 and 1/7 to decimals in order to compare with the other values
4/9=0.44
1/7=0.14
step 2
Compare the values
0.44 > 0.33 > 0.14 > 0.08
therefore
The order of preferences from greatest to least is
beam, vault, uneven bars, floor
