Answer:
r = 1.41 mm
Step-by-step explanation:
Given that,
The circumference of the flower, C = 8.9 mm
We need to find its radius. We know that,
Circumference, 
Where
r is the radius of the object

So, the radius of the object is equal to 1.41 mm.
-2x - 3x = -5x
8 - 4 = 4
-5x + 4
<u>Answer:</u>
11. g
12. f
13. e (add all the frequencies)
14. d
15. c (eg. 17.5 -8.5 = 9)
16. b
17. a
Let me know if you have any questions.
Hope this helps!
Answer:
-72
Step-by-step explanation:
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 :)
