Answer:
Step-by-step explanation:
The standard form of a circle is
If we are given x and y as 0 and 5 respectively, and we are also told that the center is (0, 0), our h and k are both 0. Filling in x, y, h, and k we can find the radius. So let's do that:
and
so
Our circle's equation is
Since the point in question, (4, 4), lies in the first quadrant, we will concentrate on that quadrant only. To fall within the circle, we can set up an inequality and test the point (4, 4). If it lies ON the circle then the equality would be true. Let's try that first:
Obviously, 16 + 16 does not equal 25, so that point (4, 4) does not lie ON the circle. In fact from that statement alone, we can determine that the point lies outside the circle because
If the inequality < were true then the point would lie inside.
Answer:
5340
Step-by-step explanation:
Now you might think that you're supposed to decrease by 45%, but that'd only apply if the population was decreasing once by 9% in the span of 15 years.
Assuming that the YEARLY mortality rate was 9%, we now know that we have to decrease 20,000 by 9%, and then decrease whatever 91% of 20,000 is by 9% again, and so on and so forth. Until the fifteenth time, where you get 5340.8389. Now, here's the thing. You cant have 0.8389 of a person, and when it comes to population, you have to round down even if you had 0.9999 of a person. You always have to round down. And so, when rounding 5340.8389 down, you get 5340. I rest my case.
Answer:
1) 2(6-8x)
2) 4(3-4x)
Step-by-step explanation:
Answer:
1.)5508 2.)5600 x^2
Step-by-step explanation:
If two figures are similar, the corresponding side ratios are equal.
If one side is 1/3 of a corresponding side from the other figure, then the ratio for all the sides to their corresponding counterparts is 1/3.
Have an awesome day! :)
