Answer: C) exactly one triangle
<u>Step-by-step explanation:</u>
Given: ∠A = 45°, ∠B = 65°, side c = 4 cm
By the Triangle Sum Theorem, ∠C = 70°
Now you have a proportion so you can use the Law of Sines to find the exact length of side a and of side b.

Thus, there is exactly one triangle.

Answer:
Step-by-step explanation:
If the Number of Sales of x units, N(x) is defined by the function:


Next, we text the critical points and the end points of the interval to see where the derivative is increasing.

Thus, the rate of change of sales
is increasing in the interval
on 10≤x≤40.
Answer:
C
Step-by-step explanation:
considering you need at least 6 people, you would either need 6 or more, so 6 or greater, so C
Answer:
Part A: one solution:
Part B: x = 3, y = 4.
Explanation:
1) Part A: how many solutions does the pair of equations for lines A and B have?
The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.
In this case, there are two straight lines, which intersect in one and only one point.
Hence, the system has one solution.
2) Part B: what is the solution to the equations of lines A and B?
The solution is the pair of coordinates of the intersection point. It is (3, 4).
Therefore, the solution is x = 3, y = 4.
