a - b + a^2 - b^2 = {group the first two terms and the last two terms}
(a - b) + (a^2 - b^2) =
(a - b) + (a - b) (a + b) =
(a - b) (1 + [a + b])
I assume this is :
3A^3 - A^2 ...... if so, the gcf is A^2...so we have
A^2(3A - 1 )
And that's it....!!!
Sine negative in 3rd and 4th quadrants
Cosine negative in 2nd and 3rd quadrants
Tangent negative in 2nd and 4th quadrants
Nope.... the √3 part can't be simplified any further.
The ratio of their volumes is the cube of the ratio of their edge lengths....so
(5/3)^3 = 125/27
The next step is to find the common denominator.....this = 30 ....so we have
4/30 + 5/30 - 7/30 =
[ 9 - 7] / 30 =
2/30 =
1/15
3y + 7 = 19 subtract 7 from both sides
3y = 12 divide both sides by 3
y = 4
I believe you want this :
10000(1.07)^40 =
about $ 149,744.58
Volume = pi * r^2 * h
Surface Area = 2 * pi * r * h
Where r is the radius and h is the height in both cases
[1-cos(^2x)]/ [sec^2x-1] =
sin^2x / tan^2x =
sin^2x / [sin^2x/cos^2x] =
cos^2x
