Considering 32 outside the square root .
Here we have to combine like terms, and like terms are 8 , 98 ,3, 32 and 5 square root x and 6 square root x .
We need to remove the parenthesis and since there is a minus sign outside the second parenthesis , so we have to flip the sign of the terms of second parenthesis. THat is
=
And that's the final answer .
Answer:
The population, after 15 hours grows from 6000 individuals to 42938 individuals.
Step-by-step explanation:
Recall the formula for exponential growth:
where the starting number of individuals in the population is (in our case 6000). "t" is the time in hours, and "k" is the rate of growth (unknown to us, but that we can find from the info they provide on how much the population grew in 2 hours.
The general exponential growth expression can then be written as:
now imposing the 2 hour condition information:
Now that we know the value of the rate of growth (k = 0.1312), we can estimate the population after 15 hours.
Now there is an important point here: If the question is what the population is after 15 hours from the starting 6,000 bacteria, then the answer is given by replacing t with 15 in the original formula:
On the other hand, if you are asked for the population 15 hours after you saw the growth of bacteria to 7800 in 2 hours, then you need to find the population after 17 hours from the very starting point (6000 bacteria). This answer is associated with a little more tricky question but worth to have in mind:
Answer:
y = 6
Step-by-step explanation:
2(2y -12) = 0
a. Distribute the problem out
4y - 24 = 0
b. Add 24 to both sides to seperate the constants and the terms.
4y - 24 = 0
+24 +24
4y = 24
c. Divide 4 out of both sides to isolate y
y = 6
d. Plug the 6 back into the equation to see if the answer is correct.
2(2(6) -12) = 0
2(12-12) = 0
2(0) = 0
Hope this helps!

Answer:
12.5
Step-by-step explanation:
First you times 45 and 25 together, since product means multilpication. 45*25= 1125
Then you add 53 and 73, which is 90. Then you divide, which equals to the sum of 12.5. Hope this helps!
