Answer:
13.125
Step-by-step explanation:
Since the triangles are congruent, you would get the equation 4z-7=11z-112.
Then, you would subtract 4z from each side, leaving behing -7=8z-112. Then, you would add 112 to each side, getting 105=8z. Divide both sides by 8, and your answer is z=13.125
Answer:
However, at the moment of death, the amount of carbon-14 begins to decrease because it is unstable, while the amount of carbon-12 remains constant in the sample. Half of the carbon-14 degrades every 5,730 years as indicated by its half-life.

Answer:
Step-by-step explanation:
(a) The appropriate formula is C = 2πr. Here r = 14 cm, so
C = 2π)14 cm = 28π cm, or (if we take π to be 22/7), C = 88 cm²
(b) We use the same circumference formula: C = 2πr and solve it for r before inserting numeric values:
C 132 m 7(132 m)
r = -------- and in this case, r = ------------------- = ------------- = 21 m
2π [ 2 * (22/7) ] 44

Answer:
that is not a function because for one value of x you get two different values of y. it is circle (x+3)^2+(y-3)^2=9. but if you divide it in two half circles (upper and lower) than you have two functions y=3+sqrt(-x^2-6x) and y=3-sqrt(-x^2-6x)
domain is x ∈ [-6,0] and range y ∈ [0,3] for one and for other y ∈ [3,6]
