280 your welcome good luck
~ : to represent sign of proportionality
y ~ 1/x
y = k/x
x=20, y=4
4 = k/20
k = (20×4) = 80
y = 80/x
x=35, y = 80/35 = 2.29
The proportional constant k = 80
The function is: y = k/x
The new value of y is: 2.29
Hope it helped!
Answer:
Doubling the actual answer and increasing it by 2.
Step-by-step explanation:
The calculator is returning 26, instead of 12. Note that 26 is 2 more than twice of 12.
i.e.
26 = 2(12) + 2
Calculator is returning 32 instead of 15. Here again we can note the same logic. 32 is 2 more than twice of 15.
i.e.
32 = 2(15) + 2
Calculator returns 202 instead of 100. Here again the same logic holds true.
i.e.
202 = 2(100) + 2
So, what the calculator is doing is:
Doubling the actual result and increasing it by 2.
Answer:
Step-by-step explanation:
2π/3 radians is equivalent to
2π 180°
-------- * ---------- = 120°
3 π rad
This angle (120°) is 30° past 90°. The 'opposite side' of the triangle formed by this ray of length 1 is √3 and the 'adjacent side' is 1.
adj side -1
cos 120° is in Quadrant II. cos 120° = --------------- = ---------
hyp 2
√3
and sin 120° = --------
