Answer:
(5, 21)
Step-by-step explanation:
The x-coordinate of the midpoint of a segment is half of the sum of the x-coordinates of the endpoints.
The y-coordinate of the midpoint of a segment is half of the sum of the y-coordinates of the endpoints.
Let the unknown point have coordinates (x, y).
x-coordinate:
(5 + x)/2 = 5
5 + x = 10
x = 5
y-coordinate:
(-1 + y)/2 = 10
-1 + y = 20
y = 21
The other endpoint has coordinates (5, 21).
Answer:
y = 12
Step-by-step explanation:
The standard form of the exponential function is
y = a
Find a and b by substituting ordered pairs from the table into the equation
Using (0, 12 ), then
12 = a ( = 1 ), so
a = 12, then
y = 12
Using (1, 34.8 ) , then
34.8 = 12 ( divide both sides by 12 )
b = 2.9
Thus exponential function is
y = 12
Answer:
4pi r
Step-by-step explanation:
We can use the Sine Law:a / sin A = b / sin B2 / sin 75° = 3 / sin B2 / 0.966 = 3 / sin B ( after that we will cross multiply )
2 sin B = 3 · 0.9662 sin B = 2.898sin B = 2.898 : 2sin B = 1.499 > 1 ( it is not possible )Answer: A ) No triangles can be formed.
