Help me pls let me know if my answer is right or not if not pls let me know the correct answer. ASAP

Answer:

7.5

Step-by-step explanation:

Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:

270/360; 360 being the total angle measurement of a circle

270/360 simplifies to 3/4

The fraction represents how much of the circle that arc covers

Now we have to find the circumference which would be

2([tex]\pi \\[/tex])r

r = 5 therefore: 2([tex]\pi \\[/tex])5 = 10[tex]\pi \\[/tex]

Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length

Which gives us 7.5[tex]\pi \\[/tex], or 23.55

Which of the following functions represents the values in the table below?

x     0         2         4         6    
f(x)     2         10         66         218    

f(x) = -3x - 2x^2

f(x) = x^2/2

f(x) = 2 + x^3

f(x) = 3x - 2
