Answer:
Step-by-step explanation:
You are given this data:
First, calculate the x points by dividing the total length in 5:
x=3,6,9,12,15
Now you calculate the half point of the x axis intervals you just calculated:
and find the function values of each of them (the Area for each cut):
A(1.5) = 18
A(4.5)=78
A(7.5)=105
A(10.5)=128
A(13.5)=38
Now you have formed the rectangles (see diagram below).
To calculate the volume, just use the next equation given by the midpoint rule:
A. is x= 3.25
b. is b=-6
i don’t really know about the rest

Answer:
Step-by-step explanation:
25+90+x+69=180
184+x=180
x=-4
