4-2 3/4= 1 1/4 (amount of water that rained into the gauge)
1 1/4= 5/4=10/8
10/8 divided by 1/8 = 10
So the rain lasted 10 hours
Answer:
see explanation
Step-by-step explanation:
We require to find the slope m of the line joining the 2 given points
To find m use the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2,3) and (x₂, y₂ ) = (1, - 2)
m = = = 5
Given a line with slope m then the slope of a line perpendicular to it is
= - = -
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept ), thus
y = - x + c ← is the partial equation of the perpendicular line
To find c substitute (- 3, 2) into the partial equation
2 = + c ⇒ c =
y = - x + ← perpendicular equation
The terms of the geometric sequence are 1,3,9, ...,
The first term is a = 1
The common ratio is r = 3.
The sum of the first 10 terms is
