Answer:
A. On the first day, 3 leaves fall.
B. D. The number of leaves that fall on a given day is 2 times the number of leaves that fell on the previous day.
Step-by-step explanation:
Given
Solving (a) The meaning of 3.
3 represents the initial number of leaves (i.e. the first day) and this proved as follows.
On the first day, n = 0.
Substitute 0 for n in
Solving (b) The meaning of 2.
2 represents the rate which leaves fall down.
In (a)
Take n = 1
Substitute 1 for n in
When f(1) is divided by f(0), the result 2. So, the number of leaves doubles everyday
Answer: Answer B maybe?
Step-by-step explanation: I'm in sixth grade, so i don't know, but I would guess its answer B, if i'm correct, i have a 4.000 G.P.A so i hope that helps?
Equation 1 + equation 2
3x-8y +(-3x+10y) = 9+(-15)
2y= -6
then y=-3
from equation 1
3x-8y=9
3x-8(-3)=9
3x+24=9
3x=9-24=-15
then x=-5
Answer:
Interest earned= $200
Step-by-step explanation:
Giving the following information:
Initial investment= $20,000
Interest rate= 3%
Inflation rate= 2%
First, we need to calculate the real interest rate. <u>The inflation rate decreases the value of money through time. We need to deduct from the interest rate, the inflation rate.</u>
Real interest rate= 0.03 - 0.02= 0.01
<u>Now, we can calculate the interest earned in year 1:</u>
Interest earned= PV*(1+i)^n - PV
Interest earned= 20,000*(1.01^1) - 20,000
Interest earned= $200
Probability of 1st number being even : 3/7
probability of 2nd number being even : 2/6
probability of 3rd number being even : 1/5
probability of all 3 numbers being even : 3/7 * 2/6 * 1/5 = 6/210 = 1/35
