Answer:
The 20th day
Step-by-step explanation:
On the first day, number of people who know the secret=2
Number of people On the second day =2X2=4
Number of people On the third day =4X2=8
We can see that on each passing day, the number keeps doubling.
This is an example of a geometric progression.
Now we are to determine the number of days when the number of people who know the secret will grow past 1,000,000
For the G.P. 2,4,8,...
a=2, common ratio, r= 2
Uₙ=arⁿ⁻¹
arⁿ⁻¹>1000000
2X2ⁿ⁻¹>1000000
2ⁿ⁻¹⁺¹>1000000
2ⁿ>1000000<2²⁰=1048576
2ⁿ<2²⁰
n<20
It means on the 20th day, more than 1 million people will have been told the secret
The equation of the line of best fit using the slope-intercept formula y=mx+b is y = x - 5
<h3>Equation of the line of best fit</h3>
A line is the shortest distance between two points. The equation in point-slope form is expressed as:
y =. mx + b
m is the slope
b is the y intercept
Using the coordinate points (25, 20) and (60, 55)
Slope = 55-20/60-25
Slope = 35/35
Slope = 1
For the intercept
20 = 1(25) + b
b = 20 - 25
b = -5
Substitute
y = x + (-5)
y = x - 5
Hence the equation of the line of best fit using the slope-intercept formula y=mx+b is y = x - 5
