Acertain type of cell can double itself every hour, because it has a growth factor of 2. a laboratory has 15 of these cells.
which function best models the amount of cells in the laboratory after x hours?
f(x)=2^x+15
f(x)=15⋅2^x
f(x)=2⋅15^x
f(x)=15^x+2

Second one

Step-by-step explanation:

Second choice.

Second one is growing by a factor of 2 because the exponent on 2 tells me that 2 is is being repeated as a factor.

If x=0 then 15*2^0=15(1)=15 which is what we have initially.

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
