Answer:
1650 yards
Step-by-step explanation:
Here, we have to find the minimal spanning tree required to span the neighborhood.
We start from house 1. The minimum distance from house 1 to house 2 is 250 yards. Now from 2, we can go to house 3,4 or 5 all having the equal distances of 400 yard from house 2. So we go to from house 2 to house 3. Now from 3, we go to house 5 which is at a minimum distance of 350 yards. Now from house 5 we go to house 4 with 300 yards and then from house 4 we go to house 6 which is at 350 yards from 4.
Thus the network is complete and the total distance covered is
= 250 + 400 + 350 + 300 + 350
= 1650 yards
This is the minimum distance by which the neighborhood can be wired.
And the tree is
Answer:
around 179,560
Step-by-step explanation:
you do the total times .33 and then with that number subtract 268,000 which should give you 179,560
We are comparing maxima. From the graph we know that the max of one graph is +2 at x = -2. What about the other graph? Need to find the vertex to find the max.
Complete the square of <span>h(x) = -x^2 + 4x - 2:
</span>h(x) = -x^2 + 4x - 2 = -(x^2 - 4x) -2
= -(x^2 - 4x + 4 - 4) - 2
=-(x^2 - 4x + 4) -2+4
= -(x-2)^2 + 2 The equation describing this parabola is y=-(x-2)^2 + 2, from which we know that the maximum value is 2, reached when x = 2.
The 2 graphs have the same max, one at x = -2 and one at x = + 2.
Hello there! I can help you! 58,500 female doctors makes up 17.9% of all registered doctors. To find the total amount of registered doctors, we can write and solve a proportion. Set it up like this:
58,500/x = 17.9/100
This is because 58,500 is part of the whole, which is represented by x. 17.9% is part of 100%. Let's cross multiply the values. 58,500 * 100 is 5,850,000. 17.9x * x is 17.9x. That makes 5,850,000 = 17.9x. Now, divide each side by 17.9 to isolate the x. 17.9x/17.9 cancels out. 5,850,000/17.9 is 326,815.6425 or 326,816 when rounded to the nearest whole number. Let's check this. 326,816 * 17.9% (0.179) is 58,500.064, which is a little off, but is very close to 58,500, and rounds off to that. x = 326,816. There are about 326,816 registered doctors in a recent year.
