Circumference (C) = 2 π r
                       122  = 2 π r
                        61/π = r
Answer to part (b): radius is 61/π ≈ 19.4

Diameter (d) = 2 r
                 d  = 2 (61/π)
                 d  = 122/π
Answer to part (a): diameter is 122/π ≈ 38.8


arc length (s) = r · Ф
THETA MUST BE IN RADIANS!
use the unit circle (or use the proportion π/180°) to discover that 30° = π/6

s = (61/π)·(π/6)
   = 61/6
Answer to part (c):arc length is 61/6

Let f(x) be a continuous function such that f(1) and f'(x)-Vx3 + 6. What is the value of,f(5)? (A) 11.446 (C) 24.672 (B) 13.446
tia_tia [17]

Answer:

f(5) = 26.672 which is option D

Step-by-step explanation:

From question, f(1) = 2 and f'(x)=√(x^3 + 6)

f(5) = f(1) + (5,1)∫ f'(x) dx

Integrating using the boundary 5 and 1;

f(5) = 2 + (5,1)∫√(x^3 + 6) dx

f(5) = 2 + 24.672

So f(5) = 26.672

When Sophia runs the 400 meter dash, her finishing times are normally distributed with a mean of 75 seconds and a standard devia
alukav5142 [94]

Answer: 90% of the time.

Step-by-step explanation: This is because you can add the two different times and the standard time of 75 seconds, divide it all by 3 leaving you with 75.2 and that is 0.2 away from the original between those times all together. Take that 0.2 and subtract it from the 1.1 deviation and you’ll get 0.9 times that by 100 and you get it in a percentage; 90%.

How Can you divide that
Archy [21]
First you ask yourself, can 8 go into 1?  The answer is no.  Can 8 go into 12? Yes, 1 time.  So you put 1 on top of the 2 and subtract 8 from 12.  That gives you 4.  Then you pull down the 8 from 128 and ask how many times can 8 go into 48?  The answer is 6.  So your answer is 16.  Hope I helped!
