7. The amount of the isotope carbon-14 has a half-life of 5,730 years. It is used to determine the age of certain archeological discoveries. Consider the function that represents the amount of carbon-14 in an archeological discovery.

Part A: Define a variable for the function and state what the variable represents.

Part B: What is a reasonable domain for the situation?

Part C: If a fossil has 240 moles of carbon-14, then write the function that represents the price of the archeological.

Part D: How much carbon-14 is in the fossil in 14 half-lives (or 80,220 years)?

r and t.

both are 64 degrees.

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
