A scientist determines that the number of bacteria in a culture is modeled by the formula A(t)=4,000e0.02t, where t is the numbe

SpyIntel [72]

Using the exponential model given, the number of bacteria in the culture after 9 minutes after the observation began will be 4789

Given the exponential model :

$A(t) = 4000e^{0.02t}$
$A(t) = Number\:bacteria\:in\:the\:culture\:after\:t\:minutes$
t = number of minutes after observation begins

The number of bacteria in the culture 9 minutes after the observation began can be calculated thus :

$t = 9 \: minutes$

Substitute 9 for t in the exponential equation :

$A(t) = 4000e^{0.02\times9}$

$A(t) = 4000e^{0.18}$

$A(t) = 4000 \times 1.1972173$

$A(t) = 4788.87$

Therefore, the number of bacteria in the culture after 9 minutes will be about 4789

PLZ HURRY!!!!!!!!! The table shows the number of candies packed by machine J. The equation shows the number of candies packed by

alekssr [168]

First, we need to make a function out of the table. This function will be in slope-intercept form. The function is y = 30x so in 11 minutes Machine J will make 330 candies. In 11 minutes Machine K will make 286. subtract 286 from 330 to get 44. Machine J will make 44 more candies than machine K in 11 minutes.
