Refer to the diagram shown below.
Let the coordinates of the rotated vector be (a,b).
From the Pythagorean theorem,
d = √(5² + 7²) = 8.6023
The angle θ is given by
tan θ = 7/5 = 1.4
θ = tan⁻¹ 1.4 = 54.46°
φ = 180 - (90 + 54.46) = 35.54°
The coordinates of the rotated vector are
a = - d cos φ = - 8.6023*cos(35.54) = 7
b = d sin φ = 8.6023*sin(35.54) = 5
Answer: (-7, 5)
Answer:
The number of sandwiches sold is 73. This is because it is multiplied by the expression for the money received per sandwich.
The cost to make each sandwich is <em>S. </em>This is stated in the first sentence of the problem.
<em />
The profit is 0.2<em>S. </em>This is because they sell each sandwich for an additional 20% of the cost ( S )
<em />
The amount of money the band receives is (<em>S </em>+ 0.2<em>S </em>). This is because it is the price per sandwich.

Answer:
slope is undefined and the y interception is not existed
Step-by-step explanation:
slope = (y-y') /(x-x') = (4 - (-5)) /(10 - 10) = 9 / 0 = undefined
since this is a vertical line, there is no y interception
