I believe the answer would be 3(n+12)
5.5x+13.5y=40
x+y=5.8
x=5.8-y
5.5(5.8-y)+13.5y=40
31.9-5.5y+13.5y=40
8y=8.1
y=1.0125 or about 1.0 hours
x=4.7875 or about 4.8 hours
1 kilowatt hour= 1KWH=1000 Watts
Average over the entire earth = 164 watts per square meter over a 24 hr day
Answer:
x-intercepts = (-3/4, 0)
y-intercepts = (0, 3/7)
Step-by-step explanation:
Answer:
(x, y) ≈ (-5.89, 1.16)
Step-by-step explanation:
We assume the CD is still accelerating at the same rate at the end of the given time period. The angular position will be found from ...
θ(t) = θ₀ + (1/2)a·t²
Filling in the numbers given, we get
θ(3.51) = (10π/180) + (1/2)(2.49)(3.51²) = 15.51306 . . . radians
The x-y coordinates will be found from ...
(x, y) = radius·(cos(θ), sin(θ)) ≈ 6·(-0.981066, 0.193674)
(x, y) ≈ (-5.89, 1.16)
_____
For the trig functions, the calculator must be in radians mode, unless you have converted the angles to degrees.
