Actual cost = bill + VAT*bill
= bill*(1 +VAT)
= £463.20*(1 +0.20)
actual cost = £555.84
Answer:
a. (-3, 2).
b. √65
c. (x + 3)^2 + (y - 2)^2 = 65
Step-by-step explanation:
a. The center is the midpoint of the diameter PQ.
= (-10+4)/2, (-2+6)/2
= (-3, 2).
b. The radius is the distance from the center to a point on the circle.
Take the point (4, 6):
The radius = √((-3-4)^2 + (2-6)^2)
= √65.
c. The equation of the circle is:
Using the standard form
(x - h)^2 + (y - k)^2 = r^2 where (h, k) is the center and r = the radius:
it is (x - (-3)^2 + (y - 2) = 65
= (x + 3)^2 + (y - 2)^2 = 65.
Answer:
B is the correct answer I believe
A) 1
B) 10/3
C) 6
D) 18/5
So only C is bigger than 4
It. Mean it 2 of 1\2 example 1\2 1\2
