Question
the coordinates of point t are (0,2). the midpoint of st is (1,-6) find the coordinates of point s.
Answer:
(10,-14)
Step-by-step explanation:
0 + x
--------- = 5 Multiply both sides by 2 ----> 0 + x = 10 or x = 10
2
2 + y
-------- = -8 Multiply both sides by 2 ----> 2 + y = -16 or y = -14
2
Therefore, the coordinates of point S should be at (10,-14)
|-11| > |-10|
this is because the absolute value is always a positive number. therefore, it is really 11 > 10.
Answer:
Step-by-step explanation:
An intercept is where the line hits the axis.
Lets start with x. The x intercept is always going to be what x equals when y = 0. So we know the second value of the x intercept is going to be 0, because the second value is y. The line hits the x axis at -1.2, so the x intercept is -1.2, 0
The y intercept it what y equals when x equals 0. So the first value is going to be 0, to represent x. The line hits the y intercept at the point 0, -0.7.
Answer:
sin 2x + cos x = 2 sin x cos x + cos x = (2 sin x + 1)cos x
Step-by-step explanation:
Given the expression: sin 2x + cos x,
then we can use the formula: sin 2x = 2 sin x cos x, which gives:
sin 2x + cos x = 2 sin x cos x + cos x = (2 sin x + 1)cos x
So there you have two expressions in terms of sin x and cos x, as requested. :D
