Answer:
Step-by-step explanation:
The general formula for continuous exponential growth is A=A0•ert, where A0 is the initial amount, t is the elapsed time, and r is the rate of growth or decay. For this problem, r=0.005, so the formula is A=A0•e0.005t.
Since we want to know how long it takes of the amount to be 275% of the original amount, we can state that A=2.75A0. Substituting that into our formula gives us 2.75A0=A0•e0.005t. Dividing by A0 yields 2.75=e0.005t.
At this point we need to take the natural logarithm of both sides:
ln(2.75)=ln(e0005t)
ln(2.75)=0.005t
t=ln(2.75)/0.005, which is approximately equal to 202.3
We round up to 203 years.
Answer:
A= (3,1) ; B=(-2,-1) ; C=(-4,1) ; D=(-4,0)
Step-by-step explanation:
Plotted points are expressed by (x,y) , where the x is equal to the value that you read on the x plot and y is equal to the value that you read on the y plot.
Answer:
A. 18 divided by 2/9
Step-by-step explanation:
To determine the number of boos that will fit into a box that is 18 inches long, we divide the length of the box by the length of the books
18 inches divided by 2/9 inches per book
This tells us how many books
copy dot flip
18 * 9/2
81 books
2x + 7 = 12
Subtract 7
2x = 5
Divide by 2
X = 2.5
Y = -2x
Y = -2(2.5)
Y= -5
