Mult. 536 by 410.  Hold the 0 for now and mult your final answer by 10.

Mult 536 by 41:  The first partial product is (536)(1) = 536.
                           The second is (536)(4) = 2144.

Align these partial products as follows:

                          536
                      2144  
                      ----------
                      219760 (we held that final 0, remember?)

Find the volume of the region bounded by the paraboloid z=x2+y2 and the plane x+y=1 in the first octant.
Scorpion4ik [409]

Answer:

Step-by-step explanation:

Given

Paraboloid z=x^2+y^2 and Plane x+y=1 are bounded to get the area

In first octant

value of x varies from 0\leq x\leq 1

value of y varies from 0\leq y\leq 1

Volume V=\int_{0}^{1}\int_{0}^{1-x}\left ( x^2+y^2\right )dydx

V=\int_{0}^{1}\left [ x^2y+\frac{y^3}{3}\right ]_{0}^{1-x}

V=\int_{0}^{1}\left [ x^2(1-x)+\frac{(1-x)^3}{3}\right ]dx

V=\int_{0}^{1}\left ( \frac{-4x^3}{3}+2x^2-x+\frac{1}{3}\right )dx

V=\frac{1}{6}

Simplify 4 times square root 24 minus 4 square root 8 plus square root of 98. 7 square root 2 23 square root 2 negative square r
enyata [817]

Answer:

The last choice: -√2 + 8√6.

Step-by-step explanation:

4√24 - 4√8 + √98

= 4* √4*√6 - 4*√4√2 + √49*√2

=  8√6 - 8√2 + 7√2

= 8√6 - √2

=  -√2 + 8√6.
