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.
The Average test score start = 100%
It increases by 10%:
100% = 1
10% = 0.10
1 x 0.10 = 0.1
1 + 0.1 = 1.1
It increases by another 15%
1.1 x 0.15 = 0.165
1.1 + 0.165 = 1.265
Remember to move the place value digit to the right two spaces to make it a percentage
126.5% increase is your answer
hope this helps

took the unit test on edge
Answer:
is correct, he determines it correctly, he solved it correctly, 238.5
Step-by-step explanation:
The 3 inside angles need to equal 180 degrees.
Angle K is given as 48 degrees.
Angle M would be 90 degrees.
Angle J = 180 - 90 - 48 = 42
Angle J = 42 degrees
