Answer:
Step-by-step explanation:
Let p be the number of trees Wangari plants, and h be the time she spends planting them in hours.
We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.
Let us find number of trees planted in 1 hour by dividing 12 by 3.
We can represent this information as:
Therefore, the equation relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.
To do this I must first determine what fraction of the circle is represented by the central angle 30°. Since there are 360° in a full circle, I can find the fraction of a circle by simplifying . The sector<span> represents of the circle. To find the </span>arc length<span>, I now need to find the circumference of the entire circle.

Answer:
R is reflexive and transitive but not symmetric.
Step-by-step explanation:
R = {(a, b); a ≤ b}
Clearly (a, a) ∈ R as a = a.
R is reflexive.
Now,
(2, 4) ∈ R (as 2 < 4)
But, (4, 2) ∉ R as 4 is greater than 2.
R is not symmetric.
Now, let (a, b), (b, c) ∈ R.
Then,
a ≤ b and b ≤ c
→ a ≤ c
→ (a, c) ∈ R
R is transitive.
Thus, R is reflexive and transitive but not symmetric.
30 divided by 3 is 10 soooooooooo........... 10-5=5! Hope this helps! :)

The equation 
represents a quadratic function. The graph of a quadratic function is a special type of U-shaped curve called a parabola. By plotting this function, we get the graph of the parabola shown in the figure below.
So, from the figure you can see that this point is and since 
this point is a minimum.
