Step-by-step explanation:
We have cartisean points. We are trying to find polar points.
We can find r by applying the pythagorean theorem to the x value and y values.
And to find theta, notice how a right triangle is created if we draw the base(the x value) and the height(y value). We also just found our r( hypotenuse) so ignore that. We know the opposite side and the adjacent side originally. so we can use the tangent function.
Remeber since we are trying to find the angle measure, use inverse tan function
Answers For 2,5
So r=sqr root of 29
So the answer is (sqr root of 29,68).
For -3,3
Use the identity
So that means
So our points are
(3 times sqr root of 2, 135)
For 5,-3.5
So our points are (sqr root of 37.25, 35)
For (0,-5.4)
So r=5.4
So our points are (5.4, undefined)
Answer:
y=3x-6
Step-by-step explanation:
(2,0). y=mx+b or 0=3 × 2+b, or solving for b: b=0-(3)(2). b=-6.
(3,3). y=mx+b or 3=3 × 3+b, or solving for b: b=3-(3)(3). b=-6.
Plugging in the two points from the graph.
Hence, y=3x-6
Answer:
106.60 cm^2
Step-by-step explanation:
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
Area of a triangle = 1/2 x base x height
1/2 x 13 x 16.4 = 106.60 cm^2
the answer is totally numbers
Answer:
5/6
Step-by-step explanation:
The answer has to be greater than 3/4, less than 1 and have a denominator of 6. So first, convert everything to sixths. 3/4 = 75% so what is 75% of 6? 4.5. 3/4= 4.5/6. And 1 = 6/6. So the answer has to be between 4.5/6 and 6/6. 5/6 is the answer. (Do not mix decimals and fractions when you are answering a problem. I just did that to show you what 75% of 6 was because it wasn’t a whole number). I hope this helps ;)
