Step-by-step explanation:
As seen from the graph, the curve crosses the x-axis when x = -1 and x = 1. The y-intercept of the curve is -1.
Hence, the quadratic equation of the curve is y = x^2 - 1.
Answer:
slope: 1

A= 3400t + 600 | given formula
21000= 3400t + 600 | substitute the altitude into the formula
20400 = 3400 | subtract 600 from both sides
6 = t | divide both sides by 3400
6 minutes

Answer:
(D) No, the answer is not reasonable. It should be about 10 pounds.
Step-by-step explanation:
Hotdog = 4 2/5 pounds
Hamburger = 3 1/2 pounds
Chicken = 2 3/10 pounds
Total
= 4 2/5 + 3 1/2 + 2 3/10
= 4 4/10 + 3 5/10 + 2 3/10
= 9 12/10
= 10 2/10
= 10 1/5
