# Aculture started with 2,000 bacteria. after 4 hours, it grevy to 2,600 bacteria. predict hov many bacteria will be present after 17 hours. round your ansver to the nearest whole number. p = aekt enter the correct answer.

207/8 is the right

77

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

Do you know the answer?
