yes
Step-by-step explanation:
1. put the compass at 3 inches
2. draw the arch mark at each end of the base line
4. put a dot were both arch marks intersect
5. draw a line connecting the triangle
6.repeat the following steps for the 4 inch triangle
Answer:
Question 1: $115
Question 2: 40 + 25x
Step-by-step explanation:
Question 1: 40 + 25*3 = $115
A quadratic's discriminant can either be more than zero, less than zero, or exactly zero. When the discriminant is less than zero, there are no real solutions and the graph won't cross the x-axis. When it's exactly zero, there will be a real double root and the graph is tangent to the x-axis. When it's more than zero, there will be two real solutions and two x-intercepts.
Our graph has two intercepts, so it needs a positive discriminant more than zero. Choice A's is negative - no.
Choice B's is zero - no.
Choice C's is positive -yes.
Thus, "C" is the possible discriminant for the given graph.
