Answer:
Third graph in the photo
Step-by-step explanation:
x^2+3x-4 can be factored as (x+4)(x-1). When y=0, x must be -4 or 1 to satisfy the equations, and thus the roots of the graph are at x=-4 and x=1. When x=0, y=(4)(-1)=-4. The only graph that satisfies both of these requirements is the third/last one.
Answer:
270 students is the highest number of students that can attend the Planetarium field trip each day

Answer: Perimeter = 6π ≈ 18.84
Area = 15π ≈ 47.10
<u>Step-by-step explanation:</u>
This is a composite of a big semicircle with diameter of 10 --> radius (r) = 5
plus a medium semicircle with diameter of 6 --> r = 3
minus a small semicircle with diameter of 4 --> r = 2
Perimeter of a semicircle = 

Area of a semicircle =
