Answer:
55.95 ft²
Step-by-step explanation:
Circumference formula: C = 2πr => r = C / (2π)
Area formula: A = πr²
Substituting C / (2π) for r in the above equation, we get:
C 47 ft
A = π( ----------- )² = π ( -------------- )²
2π (2π)
or ...
π(47 ft)² 2209 ft²
A = ---------------------- = -------------------- = 55.95 ft²
4π² 4(3.14159)²
Answer:
13/b I think
Step-by-step explanation:
a) All three athletes accelerated because the slope of every line in the beginning in positive.
b) Dash decelerated towards the end because the slope of the line representing him becomes negative.
c) Flash maintained a constant speed because the slope of his line does not change.
d) Krash's line is horizontal because he did not move for that time.
e) Flash won the race because his line reaches 100 first.
Answer:
y = 1/2 x
Step-by-step explanation:
We have the slope of 1/2 and a point of (4,2)
We can use point slope form
y-y1 = m(x-x1)
y-2 = 1/2(x-4)
Distribute
y-2 = 1/2x -2
Add 2 to each side
y-2+2 = 1/2 x -2+2
y = 1/2 x
This is in slope intercept form
