2x=x+8\ \ |Subtract\ x\\
2x-x=8\\
x=8\ \ -Tim\\
x+8=8+8=16- \ Lisa\\\\Lisa\ walked\ 16\ km\ and\ Tim\ 8km.

What is the effect on the graph of the function f(x) = 2x when f(x) is replaced with f(0.5x)? A) vertical stretching B) vertical
PtichkaEL [24]
<h3><u>Answer:</u></h3>

Option: D

Horizontal stretching.

<h3><u>Step-by-step explanation:</u></h3>

We have to find the effect on the graph of the function f(x)=2x when it is replaced by f(0.5 x).

We know that when a parent function f(x) is replaced by f(kx) then either the graph is stretched horizontally or shrinked horizontally.

if k>1 then the graph is shrinked horizontally.

if k<1 then the graph is stretched horizontally.

Hence here k=0.5<1 so the graph of the function is stretched horizontally.

What is the volume of the composite figure? (Round to the nearest hundredth. Use 3.14 for Pi.)
Natasha2012 [34]

The volume of composite figure is 385.17 cubic centimeters, if a half sphere and cone have a radius of 4 centimeters and height of 15 centimeters.

Step-by-step explanation:

The given is,

              Composite figure is combination of a  half sphere and cone

              Both have a radius of 4 centimeters

              The cone has a height of 15 centimeters

Step:1

   Volume of composite figure = Volume of half sphere + Volume of cone  

Step:2

     Formula for volume of semi sphere,

                                    Volume of half sphere, V_{Half sphere} = \frac{2}{3}  \pi  r^{3}

     Where, r - Radius of Half sphere,

     From given, r = 4 centimeters

                                    V_{Half sphere} = \frac{2}{3}  \pi  4^{3}

                                                       = (0.6667) (3.14)  (64)        (∵ \pi = 3.14 )

                                      V_{Half sphere} = 133.9733 cubic centimeters

     Formula for volume of cone,

                      Volume of cone, V_{cone} = \frac{1}{3} \pi r^{2} h

     where, r - Radius of cone

                h - Height of cone

     From given,

                 r = 4 centimeters

                h = 15 centimeters

     Volume of cone,

                                                V_{cone} = \frac{1}{3} \pi 4^{2}(15)    

                                                         = (0.333333) (3.14)(16)(15)       (∵ \pi = 3.14 )

                                                 V_{cone} = 251.1997 cubic centimeters

Step:3

        Volume of composite figure =  133.9733 + 251.1997

       Volume of composite figure  = 385.17 cubic centimeters

Result:

         The volume of composite figure is 385.17 cubic centimeters, if a half sphere and cone have a radius of 4 centimeters and height of 15 centimeters.
