Answer:
1. It has two points in common with the x-axis.
2. The vertex in relation to the x-axis is at 
Step-by-step explanation:
The points that the equation has in common with the x-axis are the points of intersection of the parabola with the x-axis.
To find them, substitute y=0 and solve for "x":
Use the Quadratic formula:
It has two points in common with the x-axis.
To find the vertex in relation to the x-axis, use the formula:
Substituting values, you get:
4x - 16 = 2x + 6
4x - 2x - 16 = 2x - 2x + 6
2x - 16 = 6
2x - 16 + 16 = 6 + 16
2x = 22
x = 22/2 = 11
so m <ABT = 4(11) - 16 = 44-16 = 28 degrees Answer
Given that 3 ties were selected and the probability of selecting a bow tie is 3%, the probability of selecting 3 bow ties will be:
P(selecting 3 ties)=P(selecting a bow tie)*P(selecting a bow tie)*P(selecting a bow tie)
=(0.03)*(0.03)*(0.03)
=0.000027
Answer:
23
Step-by-step explanation:
Ā means the average
So it means the average of 64 gave their speech which should be 64/2 = 32
So 32 gave their speeches yesterday,
7 gave today
Total number that has given is
32 + 7 = 39
Therefore the number remaining are
62 - 39 = 23
