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:
209 inches
Step-by-step explanation:
95% of 220 is 209 inches so therefor it would be 209 inches.
Rewrite the parabola in standard form and use this formula to find the vertex (h,k).
= (2,-1)
13x - 4 < 12(x-1)
13x - 4 < 12x - 12
13x - 12x < -12 + 4
x < -8
x > 8
x is greater than 8
