Center is (-6,7) and radius is 9. A circle with a center at (h,k) and a radius of r has the equation (x-h)^2 + (y-k)^2=r^2 so h= -6 k= 7 r is 9 you just work back wards, what two numbers multiplied gives you 81? Well 9

Step-by-step explanation:
Answer:
b = 5√6
c = 10√5
Step-by-step explanation:
This is a 30-60-90 triangle
the hypotenuse is always twice the short leg
c = 2(5√2)
c = 10√5
The long leg is alway √3 times the short leg
b = √3(5√2)
b = 5√6
Answer:
K = 151.9422481
Step-by-step explanation:
At the end of year 10, your perpetuity is worth 100/i
(1) is worth 90×s_{10%i}
So if you set them equal you get 90*[(1+i)^10 - 1]/i = 100/i or [(1+i)^10 - 1] = 10/9 or (1+i)^10 = 19/9 or i = 0.077583937
So now the question compare (1) to (2), at t = 0
(1) is worth 90×a_{10%i} = 90(1 - 1/(1.077583937)^10)/0.077583937 = 610.5441743
(2) is worth K×a_{5%i} = 4.018264714×K
Therefore K = 151.9422481
Step-by-step explanation:
Given
sin³ø cos ø + cos³ø sinø
= sin ø cos ø ( sin²ø + cos²ø)
= sinø cosø * 1
= sinø cosø
