If
denotes the sum of the first
terms of a geometric series with first term
and common ratio
, then
Using summation notation, you have
In this case, you have
,
, and
. So the value of the sum is
Rounded to the nearest whole number, the answer would be 3.
Answer:
1
Step-by-step explanation:
Yes it's true because:
TSR and RQP is alternating tringle
TSR & PQR is perpendicular
Answer:
x = 6
y = 45 degrees
Step-by-step explanation:
Here, we want to get the measure of x and y
For a 45-45-90 triangle, the measure of each of the internal angle asides the right angle is 45 degrees
This mean y is 45
To get x, we know we have an isosceles triangle
So the length of the third ungiven leg is x too
Mathematically, the square of the hypotenuse (side facing the right angle) is equal the sum of the squares of the two other sides
(6 √2)^2 = x^2 + x^2
72 = 2x^2
x^2 = 72/2
x^2 = 36
x = √36
x = 6
We know that the number of users triple each day
Let number of users on day 1 be x
⇒ Users on day 2 = 
= 3x
and Users on day 3 = 
= 9x
And so on...
% Increase in users from day 1 to day 2 = 
⇒ % Increase in users from day 1 to day 2 = 
⇒ % Increase in users from day 1 to day 2 = 
⇒ % Increase in users from day 1 to day 2 = 200%
Similarly,
% Increase in users from day 2 to day 3 = 
⇒ % Increase in users from day 2 to day 3 = 
⇒ % Increase in users from day 2 to day 3 = 
⇒ % Increase in users from day 2 to day 3 = 200%
Hence, we can see that the percentage increase each day is 200%
