Answer:
surface area of the balloon is 199 cm^2
T(-5,-10)
U(10,-10)
V(-5,5)
2/3 of an hour= 40 minutes
3/4 of 40= 30 minutes
40- 30= 10
So, it took Bethany 10 more minutes to complete her science homework than her math homework.
54+9= 63 m = distance and time=35 sec hence, speed= 63/35=9/5=1.8 m/s
time taken to reach water surface= distance/speed=54/1.8=30 sec
Answer:
[-20.25;+∞).
Step-by-step explanation:
1) according to the properties of the given parabola the minimum is:

2) y₀=-20.25 means, the value -20.25 is minimum of the range, the maximum →+∞;
3) finally, the range y≥-20.25.
