d. 
minutos
Step-by-step explanation:
a. Newton's law of cooling states that the speed with which a body is cooled is proportional to the difference between its temperature and that of the medium in which it is found. Then, the initial value problem is given by:
b. The differential equation obtained is a differential equation of separable variables:
c. After 33 minutes of serving the coffee has cooled to 180°:
d.
Answer:
D. 35 + 145 = x
The sum of the angles = 180 degree
Step-by-step explanation:
Answer:
a = 3 and b = 4
Step-by-step explanation:
Independent Equations
Lines intersect
One solution
In this case the two equations describe lines that intersect at one particular point. Clearly this point is on both lines, and therefore its coordinates (x, y) will satisfy the equation of either line. Thus the pair (x, y) is the one and only solution to the system of equations. One solution is called "consistent". This shows two distinct non-parallel lines that cross at exactly one point. This is called an "independent" system of equations, and the solution is always some x, y-point.
Answer:
The measure of the angle of intersection for and is 90°. As the line of reflection changes position, the angle measure stays the same.
