Answer:
207
Step-by-step explanation:
114+93=207
The easiest way is to add their absolute values together instead of 114-(-93)
Letter a is equal too -1300
and letter b =-32
hope this helps

Answer:
75°, 85°, 95°, 105°
Step-by-step explanation:
Since the 4 angles form an AP, then the 4 angles are
a, a + d, a + 2d, a + 3d
where a is the first term and d the common difference
The sum of the angles in a quadrilateral = 360° thus
a + a + d + a + 2d + a + 3d = 360, that is
4a + 6d = 360, substitute d = 10
4a + 60 = 360 ( subtract 60 from both sides )
4a = 300 ( divide both sides by 4 )
a = 75
Thus the 4 angles are
75°, 75° + 10° = 85°, 75° + 20 = 95°, 75° + 30° = 105°
Answer:
(x, y) = (600cos(10πt/9), -600sin(10πt/9))
Step-by-step explanation:
The usual translation between rectangular and polar coordinates is ...
Here, the radius is constant at r = 600 m, and the angle changes linearly with time. If we assume the initial angle is 0, then it is -2π radians (one full turn clockwise) at t=1.8 minutes. The relationship between θ and t will be given by ...
θ = (-2π)(t/1.8) = -10πt/9
Using these values for r and θ, we get the parametric equations ...
- x = 600·cos(-10πt/9)
- y = 600·sin(-10πt/9)
We can take advantage of the fact that cosine is an even function, so cos(-θ) = cos(θ), and that sine is an odd function, so sin(-θ) = -sin(θ). This lets us write the equations as ...
(x, y) = (600·cos(10πt/9), -600·sin(10πt/9))
