HELP ME PLEASE

Zina [86]

Answer:

π(5²)(13)+⅓π(5²)(12)

Step-by-step explanation:

You can find the volume of the cylinder by:

V=πr²h

which is V1=π(5²)(13)

and the volume of the crooked cone by:

⅓πr²h

which is V2=⅓π(5²)(12)

and you need the volume of the whole shape. you can find by adding V1+V2

Answer:

81 m

Step-by-step explanation:

Since x is seconds after takeoff, the value of x at takeoff is 0. You are being asked to find H(0).

H(0) = -3(0 -3)^2 +108 = -3(9) +108 = 81

The height of the hovercraft at the time of takeoff is 81 meters.

3. What are the coordinates of the points of tangency of the two tangent lines through the point (1,1) each tangent to the circl

VashaNatasha [74]

Answer: $y+x=2$

Step-by-step explanation:

Given

equation of circle $x^2+y^2=1$

Equation of tangent passing through (1,1)

Slope of tangent is given by differentiating equation of circle

$2x+2y\frac{\mathrm{d} y}{\mathrm{d} x}=0$

$\frac{\mathrm{d} y}{\mathrm{d} x}=\frac{-x}{y}$

at $(x,y)=(1,1)$

$\frac{\mathrm{d} y}{\mathrm{d} x}=\frac{-1}{1}$

Equation of line with slope

$m=\frac{y-y_0}{x-x_0}$

$-1=\frac{y-1}{x-1}$

$y+x=2$
