I will find one by one

\\ \sf\longmapsto f(x)=2x-1

\\ \sf\longmapsto f(1)=2(1)-1=2-1=1

\\ \sf\longmapsto f(0)=2(0)-1=-1

\\ \sf\longmapsto f(-1)=2(-1)-1=-1-1=-3

\\ \sf\longmapsto f(2)=2(2)-1=4-1=3

Answer:

f(1) = 2*1 - 1 = 1

f(0) = 2*0 - 1 = -1

f(-1) = 2*-1 - 1 = -3

f(2) = 2*2 - 1 = 3

Answer: 5.196152423

Step-by-step explanation: Logically considering it's a Rhombus all the sides are equal to each other. So you just need to find the area. In this case you find the area by multiplying the sin of the given angle by the square root of the given side. So, 6²×sin (60)=6²×√3/2=31.17691454. After finding the area you then have to divide the area by it's base to find the height. So, 31.17691454 ÷ 6 = 5.196152423.

I didn't round any of the numbers. Hopefully this is correct.

Sorry about the messy diagrams (never been good at creating them) and how long it took.

Does somebody know how to do this?

Answer:

Total length of running track is 371.24 m .

Step-by-step explanation:

Total running track = Running track around straight region + running track around curved region.

Running track around straight region = 2 × length of straight region

= 2×82 m

= 164 m

Running track around curved region = 2 × length of curved region

= 2 × π × radius of curved region

= 2 × 3.14 × 33 m

= 207.24 m

Therefore , total length  of running track = 164 + 207.24 m

= 371.24 m
