Answer:
(x + 2)^2 + (y - 5)^2 = 32 or [4√2]^2
Step-by-step explanation:
Here we have a circle with center at (-2, 5), which represents (h, k). Thus, the standard equation of a circle with center at (h, k), shown below
(x - h)^2 + (y - k)^2 = r^2 (where r represents the radius of the circle)
becomes:
(x + 2)^2 + (y - 5)^2 = r^2. We know that this circle passes through (-6, 1), so this last equation becomes:
(-6 + 2)^2 + (1 - 5)^2 = r^2, or 16 + 16 = r^2.
Then 2(16) = r^2.
Taking the square root of both sides yields r = 4√2.
The desired equation of this circle is then
(x + 2)^2 + (y - 5)^2 = 32 or [4√2]^2
B.) <span>counterclockwise 270°
We know, In order to change the nature of rotation, we have to subtract the angle from 360 degrees.
So, 360 - 90 = 270 [ & don't forget to change clockwise to counterclockwise ]
Hope this helps!</span>
Answer:
x = 7 x = -7
Step-by-step explanation:
n^2 - 49 = 0
+49 +49
n^2 = 49
Jack paid $ 23000 for the ring.
<u>Solution:</u>
Given that, Jack Matthew bought a new diamond ring for $20,000
Sales tax is 5% with a 10% excise tax
<em><u>To find: total price including taxes</u></em>
Given that sales tax is 5% of 20,000
Also given that excise tax is 10%
<em>Total price = cost price + sales tax + excise tax</em>
Total price = 20,000 + 1000 + 2000
Total price = 23000
Hence, jack paid $ 23000 for the ring.
The answer i think is
x is 12 y is 0
