Answer:
418 ft^3
Step-by-step explanation:
V=whl=2·19·11=418ft³
Not easy:
- 4 < x^4 + 4x^2 ---> 0 < x^4+4x^2+4 = (x^2+2)^2, so it is always positive. Always satisfied. Curious ...
Now the other one:
x^4+4x^2<21 --> x^4+4x^2-21 < 0 --> (x^2+2)^2 - 25 < 0
(x^2+2)^2<25 ->>> x^2+2 < 5 ---> x^2 <3,
So -sqrt(3)<x<sqrt(3) is the answer! Brainliest?
Acceleration = (change in speed) / (time for the change) .
Change in speed = (25 m/s - 9 m/s) = 16 m/s
Time for the change = (8 sec - 5 sec) = 3 seconds
Acceleration = (change in speed) / (time for the change)
= (16 m/s) / (3 sec)
= (5 and 1/3) m/s² .
(rounded to the nearest hundredth ... 5.33 m/s² . )
