R=(1+i/k)^k)-1 ............................
-0.48 + 1 (2/5 = 0.4)
-0.48 + 1.4 = 1.88
Answer:
Your answer is 5 weeks!!
Step-by-step explanation:
How I got my answer; First I checked if 2 weeks would work by doing 2( the umber of weeks) *3( the number of inches it grows per week) which is 6, I then added 6 to 3 inches (which is the original height of the plant) and I got 9.
I did the same process with the 2nd plant;
2(the number of weeks) *2( the number of inches the plant grows per week) which is 4. I then added 4 and 8( the original height) and I got 12.
(THE EXPLANATION FOR HOW I GOT 5 WEEKS STARTS HERE)
So I continued to do this process with 2,3,4 and 5, and finally I got my answer at 5weeks.
5(the number of weeks) * 3(the rate the plant grows per week) which is 15inches. I then added 15 to the original height which is 3inches, 15 +3 is 18 inches so that is my answer for how tall the 1st plant would get in 5 weeks .
Now the 2nd plant;
5(the number of weeks) * 2(the rate the plant grows per week) which is 10inches. Now I'm going to add the original height (8) with the rate the 2nd plant would grow after 5 weeks (10), 10+8 is 18 so the plant would grow 18inches after 5 weeks which is the same height as the first plant.
Hope this makes sense :)
If you look at the equation and solve on each end you will gat 2
Answer:
B and D
Step-by-step explanation:
PLUG AND CHUGGGG
if you don't know what that means, you're just placing the values of x and y into the equation
a) 3=3(1)-1 --> 3≠2
b) 8=3(3)-1 --> 8=9-1 --> 8=8
c) 17=3(7)-1 --> 17=21-1 --> 17≠20
d) 29= 3(10)-1 --> 29=30-1 --> 29=29
