Diametre = 2 x Radius
Radius = 7
Circumference = 2πr
= 2x22/7x7
= 44
Answer:
which math is this? what is it asking u to do
13 inches = 5 feet
----------------------------
Find 1 inch:
----------------------------
1 inch = 5/13 feet
----------------------------
Find 104 inches:
----------------------------
104 inches = 5/13 x 104 feet
104 inches = 40 feet
--------------------------------------------------------
Answer: 40 feet
--------------------------------------------------------
Find the velocity first, the "slope".
m=(y2-y1)/(x2-x1)
m=(95.5-53)/(4-2)
m=21.25 ? Your equations are wrong, I'll double check with another set of points...
m=(350.5-308)/(16-14)
m=21.25 LOL, yep none of your lines has the correct slope.
Anyway...
y=21.25x+b, using any point we can solve for the y-intercept, or "b", (2, 53)
53=21.25(2)+b
53=42.5+b
10.5=b so the distance to the lighthouse as a function of time is:
y=21.25x+10.5
So essentially, you should fire your teacher or burn that book you are using :)
With the whole question ???
