In a lab, 820 cells are present at the beginning of an experiment. During the first 6 hours, the number of cells decreased by 5% each our. to solve, write an exponential model
giving the number of cells y present t hours after starting the experiment. Estimate the
time when the number of cells is 700, to the nearest hour.

answer: asdfghjkl,mnbv

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
