harriet is cultivating a strain of bacteria has doubled by the end of every second hour. how many bacteria will harriet have in

Black_prince [1.1K]

Answer:

n2^3 bacteria, n being the initial population.

Step-by-step explanation:

compound growth equation: P=n2^t

P is total population

n is initial population

t is time

since it doubles every second hour, and there are 6 hours

6hours/2hours= doubles 3 times, thats why t=3.

How much more would $8,000 earn in four years compounded daily at 5% than compounded annually at 5%?

QveST [7]

Answer:

Given the statement:

8,000 earn in four years compounded daily at 5%

To find the amount we use formula:

$A = P(1+\frac{r}{n})^{nt}$

where P is the principal , A is the amount , n is number of times compounded per year and t is the time in year.

Here, Principal(P) = $8000, r = 5% and n = 365

Substitute these given values we get;

$A_1= 8000(1+\frac{5}{365})^{365 \cdot 4}$

$A_1= 8000 \cdot 1.000137^{1460}$

$A_1= 8000 \cdot 1.22141$

Simplify:

$A_1= \$9771.28$

To find the Interest we use formula:

$I_1= A_1-P$

$I_1= 9771.28 -8000 = \$1771.28$

It is also given that:

8,000 earn in four years compounded annually at 5%.

Here, P = $8000, r = 5% , t =4 year and n = 1

Using the same formula to calculate the amount:

$A_2 = 8000(1+\frac{5}{1})^{1 \cdot 4}$

$A_2= 8000(1.05)^4$

Simplify:

$A_2= \$9724.05$

To find the Interest :

$I_2= A_2 - P$

$I_2= 9724.05 - 8000= \$1724.05$

Then;

$I_1-I_2 = 1771.28-1724.05 = \$47.23$

Therefore, $47.23 more would $8,000 earn in four years compounded daily at 5% than compounded annually at 5%

5x−2.5+6x−3= ___ (2x−1) someone help me with this q. will mark brainliest~

cestrela7 [59]

Answer:

5.5

Step-by-step explanation:

So, this is a simple factoring problem. The answer is 5.5(2x-1). So, heres how we get that answer.

So, factoring is basically breaking down the problem into smaller parts. So once we simplify the problem, we can factor it.

Simplify by combining like terms: 5x+6x= 11x and -2.5-3=-5.5
Now we have 11-5.5=?
so, we need to have (2x-1) in our answer because the problem asks for that in the answer.
We need to find a number that satisfies the equation and answer
so, 5.5(2x) is 11x, and 5.5(-1) is 5.5.
5.5 satisfies the equation, therefore is the answer
