Answer:
The maximum temperature will be of 85 degrees, on July 15.
Step-by-step explanation:
Sine function:
The sine function oscilates between -1 and 1, and it's maximum value is:

y=60+25sin(pi/6)t
The maximum value will occur when
, and it will be of 60 + 25 = 85 degrees.
When will it occur?
First we find the value of t for which the value inside the function sine is
. So




That is the number of months after April 15, which is 3 months. So July 15.
Coefficient of 'x'= 5a
Coefficient of 'x square'= -17
Constant term = 14a
I don’t have a calculator with me use sine 20divided by Sin(60) will give you x
