Find u. write your answer in simplest radical form
natima [27]

Answer:

<em>u=6</em>

Step-by-step explanation:

Use the 45°-45°-90° triangle theorem:

hypotenuse=\sqrt{2}*leg

Insert the values:

6\sqrt{2} =\sqrt{2}*u

Solve for u. Divide both sides by \sqrt{2} and rationalize:

\frac{6\sqrt{2} }{\sqrt{2} } =\frac{\sqrt{2}*u }{\sqrt{2} }\\\\\frac{6\sqrt{2} }{\sqrt{2}}  =u\\\\\frac{\sqrt{2}}{\sqrt{2}}*\frac{6\sqrt{2}}{\sqrt{2}}\\\\\frac{6\sqrt{4}}{\sqrt{4}}\\\\\frac{6*2}{2} \\\\6=u

Finito.

Answer:

f(10x-8)=-20x+22

f(g(x))

possibly

g(-2x+6)=-20x+52

g(f(x))

What is the slope of (0,4) and (-4,-3)
prohojiy [21]

Step-by-step explanation:

Given points

( x1 , y1 ) = ( 0, 4)

And

( x2 , y2 ) = ( - 4 , - 3 )

Now

Slope(m)

= ( y2 - y1 ) / ( x2 - x1 )

= ( - 3 - 4) / ( -4 - 0)

= - 7 / - 4

= 7/4

Find volume with full working out pls asap
aev [14]
<h3>Answer: approximately 2076.56001909938 cubic cm</h3>

====================================================

Work Shown:

V1 = volume of cylinder

V2 = volume of cone on top

V3 = V1+V2 = volume of entire 3D solid figure

-----------

V1 = volume of cylinder

V1 = pi*r^2*h

V1 = pi*8.75^2*5.8

V1 = 1395.06348773471 which is approximate

----------

V2 = volume of cone

V2 = (1/3)*pi*r^2*h

V2 = (1/3)*pi*8.75^2*8.5

V2 = 681.49653136466  which is approximate

----------

V3 = V1+V2

V3 = 1395.06348773471+681.49653136466

V3 = 2076.56001909938

Answer is approximate

The units for the volume are in cubic cm.
