Answer:
(x - 3)² + (y + 4)² = 90 or [3√10)²
Step-by-step explanation:
We need to calculate the radius of this circle. To do this we calculate the distance from the center (3, -4) to the point (6, 5).
As we move from (3, -4) to (6, 5), x (the run) increases by 3 and y (the run) increases by 9. Thus, the distance between these points, according to the Pythagorean Theorem, is
r = √[3² + 9²], or r = √90, or r = 3√10.
Using the standard equation of the circle, (x - h)² + (y - k)² = r², we obtain
(x - 3)² + (y + 4)² = 90 or [3√10)²
1. 6 times 6 = 36 cm
2. 9 times 11 = 99 yd
3. 1/2(13)(8+3)
6.5(11)
71.5 ft
4. 12 times 4 = 48 m
5. 5 times 3 = 15 in
6. 8 times 4 = 32 mm
7. 1/2(8)(10+2)
4(12)
48 yd
8. 4 times 4 = 16 cm
9. 12 times 15 = 180 in
46/45. do u know how 2 do it? hope u do
Now what you want to do is 21 + (-3). Since this is the same as saying 21 - 3, the answer is 18. Therefore, the answer is 18°F.
