Answer:
(x-5)²+(y-2)²=52
Step-by-step explanation:
first find the midpoint (center of the circle)
(9+1)/2, (-4+8)/2
(5, 2) = center
then distance formula to find diameter
√(9-1)²+(-4-8)²=√64+144 = √208 = 2√52
The radius is half the diameter = √52
Formula for circle is (x-h)²+(y-k)²=r², where (h, k) is the center
Now you can plug everything in.
(x-5)²+(y-2)²=52
Answer:
False
Step-by-step explanation:
If it is a right triangle, the Pythagorean theorem will apply
a^2 + b^2 = c^2
4^2 + 5.05^2 = 6.6^2
16 +25.5025 =43.56
41.5025=43.56
This is not true so it is not a right triangle
Round to the nearest integer
4^2 + 5^2 = 7^2
16+25 = 49
41 =49
This is not true

Answer:
b = 12
Step-by-step explanation:
First, distribute 3/4 to both terms in the parentheses:
3 = 3/4(b - 8)
3 = 3/4b - 6
Now, solve for b:
9 = 3/4b
12 = b
So, the answer is b = 12
