The answer is (0,0) because it is the same differences as the others
Answer:
∠5 = 60°
∠6 = 30°
∠7 = 120°
Step-by-step explanation:
Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)
∠5 = 60°
∠6 = 30°
∠7 = 120°
Answer:
I don't know what's going on at all possible for you
Radiologically, half lives describe the amount of time it takes for half the amount of the radioactive substance to decay. If you had 100g of a radioactive substance with a half life of one week, in seven days, only 50g would remain, and after another week, only 25g.
Fifteen days contains three half lives since the half life is 5 days long. Divide the starting amount by 2 for each half life that passes.
600g - 300g (1 HL) - 150g (2 HL) - 75g (3 HL)
So, only 75g of Bismuth-210 would remain after 15 days.
Answer:
Step-by-step explanation: is given value in dollars of a stock in t months after it is purchased.
a) Substitute 1 for t
V(12) =
b) Find derivative for V
c) When V(t) = 75
d) As t tends to infinity, exponent being in negative t tends to 0
So V tends to 42(1-0)+36 = 78
