A) T(m) = -0.16m +331.3
B) T(2015) = 8.9 . . . seconds
_____
The linear regression function of a graphing calculator can find the equation of the line easily. Or, you can use the 2-point form of the equation of a line.
.. T(m) = (10.5 -14.5)/(2005 -1980)*(m -1980) +14.5
.. T(m) = -0.16(m -1980) +14.5
Answer:
-5x-10
Step-by-step explanation:
------------------------------
(75c^2d^4f^8)/(15cd^3f^4)
75/15 x c^2d^4f^8 over cd^3f^4
5 x c^2d^4f^8 over cd^3f^4
5c^2-1d^4-3f^8-4
5c^1d^4-3f^8-4
5c^1d^1f^8-4
5c^1d^1f^4
5cd^1f^4
5cdf^4 or option A.
