Answer:
27.27cm²
Step-by-step explanation:
∅=125° r=5m
A=∅/360×πr²
A=125/360×3.142×5²
A=27.27cm²
Answer:
C: strong
Step-by-step explanation:
Its basically asking if the line going through the points fits them. Parabolic would mean the trend line is a parabola, which its not. a parabola is a curved line. weak would mean it doesnt follow most of the points. strong would mean it does follow most of the points, which it does. negative, im guessing would mean it follows none and is completely separate from the points. hope this helps.
25/100 =0.25
10 x 0.25= 2.5
X=15. This is the Altitude theorem which is Altitude/Part = Altitude/Other part. In this question you would set up the proportion 9/X = X/25 and multiply cross products to get 225=X^2. Then you undo X^2 by doing the square route of 225 and then you get 15 as the final answer.
