there is an Instagram argument - most people say the answer is 10 - but some people say it is 16. Stating if the problem was stated as 2 + (2 x 4) the answer would then be 10 by doing the …

May 10, 2017 · First, multiply 2 by the x in the parentheses. That gives you 2x. Then multiply that 2 by the 2 in the parentheses - that gives you 4. So... 2(x+2) = 2x + 4. Then, minus 4x. So you …

Apr 29, 2023 · R(x) is the distance from the axis of revolution to the outer curve, which is y = x^2. Since we are rotating about the line y = 1, we need to shift the curve up by 1, so R(x) = 1 + x^2 …

It would look like this: 4 x 3 = 12. 4 is positive, 3 is positive, thus, 12 is positive. We know that 4 and 3 are both positive because there are no negative signs in front of them. Rule 2: A positive …

(a) S rests on the xy-plane, and its base is the region bounded between f(x) = sin(π/4 · x) and g(x) = cos(π/2 ·x)−1 on 0 ≤ x ≤ 4. Cross-sections of S perpendicular to the x-axis. are isosceles …

May 31, 2024 · dV = 2 π r h dr = 2 π( 2-y)(4 - 4y 2)dy. V = 2 π ∫ 0 1 ( 2-y)(4 - 4y 2)dy = 26/3 π. Washer Method (just to double check) Solving for y give the curve as. y = x 1/2 /2. Given the …

Oct 20, 2017 · 3x^2 + x - 4 factor out the 3 . 3 [x^2 + (1/3)x - (4/3) ] Take (1/2) of (1/3) = 1/6.....square this = 1/36.....add it and subtract it
