Answer:
B
Step-by-step explanation:
So first I solved for y. The angle boc and cod together have to be 180 degrees so I subtracted 180 from 45 and then divided by 5. I got 27. Then since I knew what y was I could solve x. Since 5 times 27 is 135. I just plugged in 22 and 23 and realized it had to be 22.

Answer: A. True</h3>
=====================================================
Explanation:
Let x be the number of years since 1995. So x = 0 represents 0 years from 1995, x = 1 is 1 year after 1995, and so on.
The first row of the table is (x,y) = (0, 625) with y being the number of salmon.
The second row is (1, 400).
Let's find the slope of the line through these two points.
m = (y2-y1)/(x2-x1)
m = (400 - 625)/(1 - 0)
m = (-225)/1
m = -225
This tells us the salmon population dropped by 225 in the course of a year from 1995 to 1996.
-------------------------------
The third row shows (2, 225). Let's find the slope of the line through the two points (1, 400) and (2, 225)
m = (y2-y1)/(x2-x1)
m = (225 - 400)/(2-1)
m = (-175)/(1)
m = -175
The slope is different from the previous result. Because of this discrepancy, this means we do not have a linear model. The slope should be the same for any two points you pick from this table if you wanted a linear model.
Put another way, there is less steep a drop of the population, and the decay curve is slowly flattening out.
Answer:
20
Step-by-step explanation:
2, 5, 9, 14, ?, 27.
2,5 the number added is 3
5,9 the number added is 4
9,14 the number added is 5
14,20 the number added is 6
20 , 27 the number added is 7
Answer:
14: 104.5 square inches
15: 706.5 square inches
Step-by-step explanation:
14: 19x11= 209
209/2= 104.5 square inches
15: formula: pi times the radius squared
15x15= 225
225x3.14= 706.5 square inches
I dont know sorry,hope you find someone that helps tho!!
