An oval track is made by enclosing semicircles on each end of a 58 m by 116 m rectangle. find the area enclosed by the track. use 3.14 for pi.

IF the semicircle is on the 58m end then:

L=2*116+3.14*58

L=232+3.14*58

L=232+182.12=414.12 m. ans. for the length.  

A=58*114+3.14(58/2)^2

A=6,612+3.14(29)^2

A=6,612+3.14*841

A=6,612+2,640.74

A=9,252.74 m^2. ans.

IF the semicircircle is on the 116m end then just replace the 58 by 116.

116

Step-by-step explanation:

I hope that helped :)

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
