It was 63 degrees fahrenheit.
We have to simplify this as a product of fractions. Notice that the 6 has a negative sign, therefore, the result will be negative. We have then:

therefore, the simplified result is -2
Answer: Lines R and B are perpendicular
Step-by-step explanation: Slope of R is -1 and the slope of B is 1. Perpendicular lines have opposite slopes
By letting

we get derivatives


a) Substitute these into the differential equation. After a lot of simplification, the equation reduces to

Examine the lowest degree term
, which gives rise to the indicial equation,

with roots at r = 0 and r = 4/5.
b) The recurrence for the coefficients
is

so that with r = 4/5, the coefficients are governed by

c) Starting with
, we find


so that the first three terms of the solution are
