For each <em>x</em> in the interval 0 ≤ <em>x</em> ≤ 5, the shell at that point has
• radius = 5 - <em>x</em>, which is the distance from <em>x</em> to <em>x</em> = 5
• height = <em>x</em> ² + 2
• thickness = d<em>x</em>
and hence contributes a volume of 2<em>π</em> (5 - <em>x</em>) (<em>x</em> ² + 2) d<em>x</em>.
Taking infinitely many of these shells and summing their volumes (i.e. integrating) gives the volume of the region:
B -4-1 because the one is positive and the 4 is negative
Travis got 43 dollars
Robin collected 35 percent more so we can model this with
Travis + (Travis x .35)
43 + 15.05 =58.05
Jessica colelcted 20 percent less so
Travis - (Travis x .20)
43 - 8.6 = 34.3
34.4 + 58.05 + 43 = 135.45
C is the closest
Answer:
write this:
<BAC=x(alternate segment theorem)
<ABC=x
triangle ABC has 2 equal angles so it is an isosceles triangle.
Answer:
i got -45, so make sure you wrote the problem right because i solved correctly.
