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:
182 days
Step-by-step explanation:
Given:
Date on which loan is made = March 12
Due date of the loan = September 10
Now,
The months in between March and September and the number of days in the particular months are
Month Number of days
April 30
May 31
June 30
July 31
August 31
------------------------------------------
Total number of days = 153
also,
Number of days left in March after 12 are (31 - 12 ) = 19 days
and,
Number of days in September before the due date = 10 days
Hence, the total time for loan = 19 + 153 + 10 = 182 days
since the included months does not have the month of February. Therefore,
the time for both leap year and non-leap year will remain same.
Answer:
Well, I think that the 50% coupons would give you only 50% off of your entire purchace. Not 100% off.

Answer:
27, you need to simplify both sides of the equation to get x on one side.
Step-by-step explanation:
Answer:
D. larger than volume.
Step-by-step explanation:
Volume is just the space provided within something, while the mass is the weight of the something being evaluated. The bigger the volume, the larger the mass will be.
