Answer:
y = - 2
Step-by-step explanation:
Locate x = 2 on the x- axis, go vertically down to meet the graph at (2, - 2 )
Then when x = 2, y = - 2
Answer:
-90° = 3π/2 radians
Step-by-step explanation:
Keep in mind that -90° represents a 90° clockwise rotation from the positive x-axis. This is the same as a 360°-90°=270° counter-clockwise rotation from the positive x-axis.
To convert from degrees to radians, we simply multiply the degrees by π/180 radians. So, the answer is (270)(π/180)=(270π/180)=3π/2 radians
Answer: The distance between the birds is about 77.78 yards.
This is a trigonometry problems, so it helps to draw a right triangle between the birds. The length between them is the hypotenuse and we have a angle of 40 degrees by the sparrow. The side opposite the sparrow is the difference in heights of the birds, 50 yards.
Therefore, we can write and solve the following sine relationship.
sin(40) = 50/x
0.6428 = 50/x
x = 77.78 <span />
Answer:
(1,-7)
Step-by-step explanation:
1) (5,-4). 4 units to the left will be (1,-4)
2) (1,-4). 3 units down will be (1,-7)
U got to divide 78 and 12 then
