4^4 * 4^(-9) = 4^(4-9) = 4^(-5) or 1/(4^5)
Answer:
Step-by-step explanation:
Answer:
(x-1)²+(y-3.5)² = 265/4
Step-by-step explanation:
first find the midpoint (center of the circle)
(9+-7)/2, (2+5)/2
(1, 3.5) = center
then distance formula to find diameter
√(9- -7)²+(2-5)²=√256+9 = √265
The radius is half the diameter = (√265)/2
Formula for circle is (x-h)²+(y-k)²=r², where (h, k) is the center
Now you can plug everything in.
(x-1)²+(y-3.5)² = 265/4
Answer:
9.6
Step-by-step explanation:
10 = 8
12 = x
then simply solve for x
2/10 of a gallon. 1/10 is half so then 1/10 times 2 would equal 2/10
