Answer:
See explanation for answer
Step-by-step explanation:
A)
Setting the two equations equal to each other:
x^2-2x=8
x^2-2x-8=0
(x-4)(x+2)=0
x=-2,4
To find the intersection points, since you know the x values and you know that it intersects with the line g(x)=8, all of the y coordinates will be 8. Therefore, the coordinate pairs area (-2,8) and (4,8).
B)
I added the file with the graph.
C)
This can be solved by using integration, and yields 36 square units.
Hope this helps!

Answer:
The initial temperature of the object was 37.6 degrees Celsius
The initial temperature of the object was 37.6 (without units)
Step-by-step explanation:
we have
where
f(t) represent the temperature of the object in degree Celsius
t is the time in minutes
<em>Find the value of the constant C</em>
we have the ordered pair (4,35)
substitute in the equation and solve for C
Find the initial value of the object
we know that
The initial temperature is the value of f(t) when the value of t is equal to zero
so
For t=0
therefore
The initial temperature of the object was 37.6 degrees Celsius
The initial temperature of the object was 37.6 (without units)
