Answer:
X^2+7x+4
Step-by-step explanation:
Answer:
-27
Step-by-step explanation:
Draw a big X over the equal sign, then cross multiply the terms to get:
6(p) = 9(p+9)
Then you want to get p by itself.
- Multiply the 9 out:
- 6p = 9p+81
- Subtract 9p from both sides:
- -3p = 81
- Divide -3 both sides to get p by itself:
- p = -27
To solve this question, let's find the surface area of the entire pie and then divide it by 6 for each slice.
The area of a circle is pi*r^2. We are given the diameter, so divide that by 2 to get the radius.
Now that you have the area, divide by 6. That is the area of each slice. The problem asks for the area of 2 slices though, so multiply that by 2.
Answer:
Approximately 920.324 p/m
Step-by-step explanation:
so to figure this out, we need to simply divide 6,688 people by 7.267 square miles. 6,688/7.267=920.324.... So we have approximately 920.324 people per square mile
This is a strange question, and f(x) may not even exist. Why do I say that? Well..
[1] We know that f(a+b) = f(a) + f(b). Therefore, f(0+0) = f(0) + f(0). In other words, f(0) = f(0) + f(0). Subtracting, we see, f(0) - f(0) = f(0) or 0 = f(0).
[2] So, what's the problem? We found the answer, f(0) = 0, right? Maybe, but the second rule says that f(x) is always positive. However, f(0) = 0 is not positive!
Since there is a contradiction, we must either conclude that the single value f(0) does not exist, or that the entire function f(x) does not exist.
To fix this, we could instead say that "f(x) is always nonnegative" and then we would be safe.
