pls help me i beg u i am sorry i never answered ur question thx though
CommentThe measurement of an arc in degrees is the same as the central angle. We must assume that the central angle is the measurement given.
= 49
To find the next one you need to find the measurement from B to C, the arc that is over 180 degrees. Maybe you could put another letter between B and C so that we could refer to that top arc greater than 180 degrees. Call the point you inserted D.
= 360 - 49 - 107 = 204
=
+
Arc(
ABC) = 204 + 49 = 253
Arc(
BAC) = Arc(BC) + Arc(AB)
Arc(
BAC) = 107 + 49
Arc(
BAC) = 156
Arc(
ACB) = 107 + 204 = 311
Answer:
Your solution is (1, -4)
Step-by-step explanation:
The equations both equal <em>y</em>, so you can set them equal to each other.
y = -4x
y = -3x - 1
-4x = -3x - 1
add 3x to both sides
-x = -1
divide both sides by -1 for x to be positive
x = 1
plug x back in
y = -4(1)
y = -4
y = -3(1) - 1
y = -3 - 1
y = -4
Your solution is (1, -4)
Answer:
y = 3/4x - 8/3

Answer:
4 seconds.
Step-by-step explanation:
The given equation is
where, h is height in feet of a golf ball above the ground after being hit into the air and t is the number of seconds elapsed since the ball was hit.
We need to find the time for the ball to hit the ground.
At ground level the height of ball is 0, i.e., h=0.
Using zero product property, we get
Therefore, it will take 4 seconds for the ball to hit the ground.
