Let's formulate an equation first. For exponential growth, we follow the formula. b = 800, r - 0.027. Hence,
y = 800(1+0.027)^t
Then, at t = 21, y will be determined
y = 800 (1+0.027)^21
y = 1399.81 = 1400
Thus, the amount of bacteria present after 21 hours is 1400.
Answer:
I solved this like you would a system of equations - if that is not the answer you need LMK
Point form:
(- 1/11, 32/11)
Equation Form:
x = -1/11, y = 32/11
Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
Answer:
162 km per hour
Step-by-step explanation:
Hi!
Speed=Distance x Time
So... 3 x 54 = 162
Hope this helps :)
