Answer:
Therefore,
Step-by-step explanation:
Unit Circle:
In mathematics, a unit circle is a circle with a unit radius. Frequently, especially in trigonometry, the unit circle is the circle of radius one centered at the origin (0, 0) in coordinate System.
So the coordinate of point P on the circle is given as,
Here,
Given:
P(-3,2)
So if Radius is one unit i.e r = 1 then on Comparing we get
∴
Therefore,
Answer:
$2.5
Step-by-step explanation:
10% in decimal form is 0.1 which is multiplied by 25 to find 10%.
Answer:
20%
Step-by-step explanation:
6.25 times 20% or 0.2 = 1.25. therefore she tipped the sever 20% of the total cost of her meal.
Answer:
-2
Step-by-step explanation:
The gradient = rise/ run
= (0-6)/(3-0)
= -6/3
= -2.
the sum of the interior angles of a quadrilateral is 360°
[360 - (40 * 2)] : 2 =
280 : 2 =
140°
-------------------------------
140 + 140 + 40 +40 = 360°
