Yes, it is right.
You need to isolate P from the rest. Basically you do opposite operations to isolate a variable. In this case, subtract 5/3 on both sides: then P = q - 5/3
Here is the answer: Let S represent the sum of the expression then: S = 1/5 + 1/5^2 +... + 1/5^n ---- (a) multiply both sides by 1/5 (1/5)S = 1/5^2 + 1/5^3 +.. + 1/5^n + 1/5^(n+1) ---- (b) use equation (a) subtract equation (b) (4/5)S = 1/5 - 1/5^(n+1) multiply 5 on both sides...

Hi, You need to draw f(x) =1/x first and then transform it to f(x) = (1/x) - 4 To draw f(x) = 1/x, all you need to do is find several points, example: let x=1, then f(1)=1, you get one point (1,1) let x = 0.5, f(0.5)=1/0.5=2, another point (0.5,2). Try to get 5-10 points and t...
Yes it is suppose to be f(n) = n^2 + 4n is O(n^2) : Hi, I assume n>1. let g(n)=n^2 This is straight forward according to big O notation. f(n) = n^2 + 4n <= n^2 + 4n^2 = 5n^2 That means |f(n)|<=C|g(n)| where C is a constant. According to big O definition f(n) is O(n^2)
a math expression has meaning in it, it is not just a bunch of operations. The older of operations is a set of rule that everybody will follow so that we have a solid foundation to communicate with each other so that the meaning in an expression can be delivered without distor...
Linear model mean the rate of change is constant. SO the rate is (4.4-24.3)/45 = 0.442 a) So the model function is f(t)=24.3 -0.442t b)in year 1975, t=30 f(30)=24.3-0.442*30 = 11.04 about 11 million. c) in year 1980, t=35 f(35)=24.3-0.442*35 = 8.83 million
hint: how are diameter and circumference related? How are radius and diameter related?
This is the reason, using 1/2 + 1/3 as example: the denominator means the number of equal parts you divide the whole thing into. 1/2 means you divide the whole thing into 2 equal parts and you take one part. 1/3 means you divide the same whole thing into 3 equal parts and you ...
