Answer:
Step-by-step explanation:
Here we have KP = PE (tangents from outside the circle)
Therefore, 2KP = PE + 1 = KP + 1
Hence, 2KP - KP = 1 or KP = 1 = PE
Since KE is the base of triangle KPE, where ∡ KPE = 60, and KP = PE, we have an isosceles triangle such that ∡PKE = ∡PEK
Hence, in ΔKPE, ∡KPE + ∡PKE + ∡PEK = 180
Therefore, 60° + ∡PKE + ∡PEK = 180
Hence, ∡PKE + ∡PEK = 180° - 60° = 120°
Because ∡PKE = ∡PEK, (base angles of isosceles triangle), we have;
∡PKE + ∡PEK = 2·∡PEK = 120° which gives
∡PEK = 60° = ∡PKE
Therefore, ∡KPE = ∡PEK = ∡PKE = 60°
Hence, ΔKPE is an equilateral triangle and KP = PE = EK = 1
EK = 1.
(h,k) center point
(-6,9) is the center point
h=-6
k=9
radius or r=3
Standard form is (x-h)^2+(y-k)^2=r^2
Equation of the circle is (x+6)^2+(y-9)^2=9

Step-by-step explanation:
Calculate each one...
cineplex = 1)
mr movie = 2)
stadium cinema = 3)
theatermania = 4)
1) 0.0825/per ounce
2)0.07291666.../per ounce
3) 0.0580357/per ounce
4) 0.05514/per ounce
by reading this ^^^^^
you can tell that 1) or cineplex is the best deal
When you want to increase percentage, you divide the percentage by 100 and add it to 1. When you want to decrease, you divide the percentage by 100 and take it away from 1.
Therefore, I think:
a) 429 X 1.31 = 561.99
b) 345 X 0.88 = 303.6
