Answer:
2(n - 6)
Step-by-step explanation:
Difference = n - 6
Twice the Difference = 2(n - 6)
Making C the subject of the formula gives; C = R - P
<h3>How to find the subject of the formula?</h3>
The subject of a formula is the variable that is being worked out. It can be recognized as the letter on its own on one side of the equals sign. For example, in the formula for the area of a rectangle A = b h. Where A is the subject of the formula.
We are given the formula;
R - C = P
Now, to make C the subject of the formula, let us first add C to both sides to get;
R = P + C
Subtract P from both sides to get;
C = R - P
Thus, making C the subject of the formula gives; C = R - P

How many cakes do you have, just get a calculator and multiply the number of cakes by 2.25 to get the total amount of money.
Answer:
Step-by-step explanation:
Amount = Rs 8820
Compound Interest = Rs 820.
Step-by-step explanation:
We have to find the amount and the compound interest on Rs. 8000 at 5% per annum for 2 years compounded annually.
Let the Principal sum of money = P
Rate of Interest = R
Time Period = T
Amount of money = A
As we know that Amount formula for compounded annually is given by;
Amount =
Or
Now, we are given with P = Rs 8000 , R = 5% p.a. and T = 2 years; we have to find the amount,i.e;
A =
A =
A = Rs 8820
That means Amount = Rs 8820
Also, Compound Interest formula is given by;
Amount = Principal + Compound Interest
Compound Interest = Amount - Principal
= Rs (8820 - 8000)
= Rs 820
Therefore, amount and the compound interest on Rs 8000 at 5% per annum for 2 years compounded annually are Rs 8820 and Rs 820 respectively.
1) c) y = 500 * 2^x
In year 1, x = 1 and the population is 500 * 2^1 = 1000
In year 2, this doubles to 500 * 2^2 = 500 * 4 = 2000
ans so on
This model describes the population doubling every year
2)
A) 3 (1/2)^x and C) (0.25)^x
These numbers reduce as x increases because there is a number with an absolute value less than 1 is being raised to the power of x. They also will never totally reach zero or become negative, but will approach zero as x becomes very large.
