Answer:
The answer would be C. An obtuse equilateral triangle :)
So just divide 100 by 25 which equals 4 then divide 120 by 30 which also equals to 4 and if the rest equal 4 then its proportional (1)
And then same for 2 and 3 just divided the bottom by the top and if they all get the same answer they are proportion and if one is not the same then it’s not
For the grids if the dots are line diagonally straight and it starts at the 0 then it’s proportional if not then it’s not
Hope this helps :)
Answer:
f(1) ≈ 2.7864
Step-by-step explanation:
You appear to want a couple of iterations of ...
... y[n+1] = y[n] +arcsin(x[n]·y[n]}·(x[n+1] -x[n])
... x[n+1] = x[n] +0.5
... x[0] = 0
... y[0] = 2
Filling in the values, we get
... y[1] = 2 + arcsin(0·2)·0.5 = 2
... y[2] = 2 + arcsin(0.5·2)·0.5 = 2 +(π/2)·0.5 ≈ 2.7864 . . . . corresponds to x=1
Angle NLM is 78 degrees
A way to do this is to find the arc measure of NM and then divide it by 2 to find the angle of NLM
So first subtract
360-110=250
To find the remaining amount of the arc measures. Which is 250 degrees
Next set arc measures NM and ML together to 250 to find what x equals.
14x+16+9x+4=250
Combine like terms
23x+20=250
Subtract 20 from both sides
23x=230
Divide 23 from both sides
x=10.
Then substitute 10 for the equation representing the arc measure of NM.
14(10)+16
140+16
156
The arc measure of NM is 156 degrees
The angle NLM is an inscribed angle. Meaning that it is half of the arc that intersects.
156/2
78
Angle NLM is 78 degrees
Answer:
-2
Step-by-step explanation:
rise over run is 2/1 and y is decreasing as x is increasing so its negative
