Answer:
8 minutes if Jane was assumed to be stationary
Step-by-step explanation:
The question is on relative speed
First find the distance covered by Jane when Sally left school
Speed=Distance/Time ⇒⇒ Distance=Time×Speed
Time=10minute=10/60 hrs
Jane's speed= 12mph
Distance covered by Jane when Sally left school was= 12 ×10/60 = 2miles
So, when Sally left school, Jane was 2 miles away. To find the time Sally requires to catch up with Jane;
Time=Distance/speed
Time of meeting =2/15 hrs ⇒⇒ 2/15 × 60 =8minutes
Answer:
1,000
Step-by-step explanation:
5/10ths of a percent of what number is 5-which would be 1000
I think the answer is 301.6?
Using the Factor Theorem, it is found that yes, it is possible for a sixth degree polynomial function with integer coefficients to have no real zeroes, as they can have three complex-conjugate pairs.
<h3>What is the Factor Theorem?</h3>
The Factor Theorem states that a polynomial function with roots is given by:
In which a is the leading coefficient.
If a complex number is a root of a function, it's conjugate will also be a root. Thus, with three pairs of complex-conjugate roots, for example, , a sixth degree function with no real zeros is formed, so the answer is Yes.

Answer:
Approximately 120.31 people per square mile
Step-by-step explanation:
1) The population density can be found by dividing the whole population over the area.
2) Since the NH map is modeled like this triangle, let's firstly calculate its area.
3) Based upon the original picture, and tracing it on we can easily see that the y coordinate is little bit over 200, precisely 220. Each mark on the original y-axis count as 20 miles. That'll give us the height.
The base of the triangle is 100 miles for F(100,0). Plugging that information on the formula:
4) The Population density:
