Answer:
A=2πrh+2πr^2
Step-by-step explanation:
Unless told otherwise, the center ofrotation<span> is the </span>origin<span> (0, 0).</span>
(4x-3)(2x+1) expand the brackets: 8x^2 -2x -3 = area
3/6x+9=8
3x+9=8
3x=-1
x= -1/3
Answer:
t = (C - 3*A)/B + 3
Step-by-step explanation:
Given in the question that,
the speed with which canoe travelled for first 3 hours = A
the speed with which he travelled for any and all time thereafter = B
As we do not know the values of A, B, or C, so the answer will be an expression for C in terms of A and B.
<h3>Formula to use</h3>
distance = speed x time
C = A*3 + B*(t-3)
Rearranging and solving for t
C - (A*3) = B*(t-3)
C - (A*3) = Bt - B3
C - (A*3) + B3 = Bt
t = C - (A*3) + B3 / B
or
t = (C - 3*A)/B + 3
