The intersection points of the equations represents; C: The time when the height of the ball and the bird are the same.
We are given;
The height of the baseball over time:
h = -16t² + 65t
The height of the bird over time:
h = 8t + 20
The intersection point will be the value of t when; 8t + 20 = -16t² + 65
Rearranging gives;
16t² + 8t - 45 = 0
Using online quadratic equation calculator gives us;
t = -1.94 s or t = 1.44 s
Now, since both equations measure height vs time, it means that the points of intersection tell us the time when the height of the ball and the bird are the same.

Answer:
36
Step-by-step explanation:
As the triangle ABC is isosceles so A and B has the same measures
And, the sum of the angles is 180°.
Therefore 2 times the measure of angle
B plus 120° = 180°,
So, the equation:
2x + 120 = 180
So x = 30
Now we have to apply the law of sin on the triangle BMC as shown below:
Now calculate for BC
BC = 20.7
We use the law of sin again i.e
So AB is 36
, so corresponding sides occur in some ratio with one another. In particular, the order the vertices tells you that
Answer: 1 month = 500ml
4 month = 500ml × 4 = 2000ml = 2L
you should use the 2L container
