Answer:
Here's what I get.
Step-by-step explanation:
9. (6, -8)
The reference angle θ is in the fourth quadrant.
∆AOB is a right triangle.
OB² = OA² + AB² = 6² + (-8)² = 36 + 64 = 100
OB = √100 = 10

10. cot θ = -(√3)/2
The reference angle θ is in the second quadrant.
∆AOB is a right triangle.
OB² = OA² + AB² = (-√3)² + (2)² = 3 + 4 = 7
OB = √7

The answer is graph number 2
Answer:
1) (-3,-2)
2) x=-3
Step-by-step explanation:
1) The vertex of a parabola is the turning point that is the minimum or maximum of the graph, based on the shape of the parabola. In this case, the vertex is the minimum. By looking at the coordinate points, we can tell that the minimum value where the graph changes the direction is at (-3,-2).
2) The line of symmetry is the line on the graph that cuts the shape exactly in half. This means that if you were to fold the graph along this line, the two sides would be identical. All parabolas have a line of symmetry and it always matches the vertex. The equation for the line of symmetry will be x= whatever the x-value of the vertex is. So, for this graph, the line of symmetry is x=-3.
Sanjay, because quarts are twice as big as pints.
Step-by-step explanation:
Given
Milk quantity for Lisa = 3 quarts
Milk quantity for Sanjay = 12 pints
We have to convert both quantities in same unit so that we can compare both quantities.
We know that there are two pints in a quart.
So,
Lisa will have:
3*2 = 6 pints of milk
Hence,
Sanjay, because quarts are twice as big as pints.

Answer:
You will drive 5 kilometers a second
Step-by-step explanation: To determine how many kilometers you will drive in one second, you need to take the data already given to you and use it to solve this problem. First you need to take the amount of kilometers you drive in 20 seconds which is 100, and divide it by 20 to find out the answer to this problem.
