2020年1月29日 · 0.25 (x-4) = 1+ 5. now the right hand side adds to a small number '6' 0.25 (x-4) = 6. the left hand side has our variable x between brackets where the bracket is multiplied by 0.25, there is two steps to isolate x, we need to get rid of the 0.25 and we need to …

2014年6月19日 · I think the easiest way to solve is to rewrite 25 as 5^2 and then observe (due to multiplication of expos) that the problem can be re-written as 5^(2x-2)=5^(3x+1). we can apply the log based 5 to both sides, thereby inverting the expo function and are left solving a one-variable linear equation:

2020年2月18日 · The volume generated by rotating this region about the y-axis is ∫πr 2 dy (as y goes from 0 to 4) because the cross sections are disks. The radius is √25 - y 2 (i.e., for each y, the radius is the x value for which (x,y) is on the circle). For the modified problem, V = ∫π(√25 - y 2) 2 dy; lower limit of integration is y=0 and upper ...

symbol. A * symbol is not necessiary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying parentheses, example: (x + 1)(x – 1). Order of Operations

2023年2月15日 · ∫ 0 6 2πx√(100 - x 2)dx. If x = 6 was not meant to be included, we could compute the volume by integrating with respect to y instead, using disks (in which case the integrand represents the area of a circle, πr 2): ∫ 0 10 π · (100 - y 2) dy. The latter integral should yield 2,000π / 3 , as that is the volume of a hemisphere with r = 10.

2020年8月4日 · This is then (sinx)/(1-sin^2x). 1-sin^2 x = cos^2 x so this simplifies to (sinx)/(cos^2 x) = (sinx)(cosx) x 1/cos x= (tan x )(sec x)

2020年12月2日 · the areas are 3 x 33.75 = 101.25 and 3 x 15.75 = 47.25 hence our approximation is 2 x (101.25 + 47.25) = 297 units 2 For most accuracy, we must integrate the function.
