The radius of the circle ( which is the same as the distance from the epicenter) = square root of 2500 which is 50
Answer is 50 miles.
To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.
N(2n+6)-(n²-1)= 2n²+6n-n²+1=n²+6n+1
Answer:
Step-by-step explanation:
Hi!
Lets call:
T = temprature of the object
T₀ = temperature of surroundings
t = time
The rate of change of T is its derivative with respecto to time. If T > T₀, the object looses heat, so T decreases. Then, being k > 0:
In this case T₀ = 70ºF and k = 0.05/min. Then the differential equation is:
The answer for the first question would be 3952+3952 =7903
