To calculate the velocity, we use the given expression above which is <span>s(t) = −16t^2 + 144. First, we calculate the time it takes to reach the ground. Then, differentiate the expression and substitute time to the differentiated expression.
</span>s(t) = −16t^2 + 144
0 = -16t^2 + 144
t = 3
s'(t) = v = -32t
v = -32(3)
v = -96
Note: negative sign signifies that the object is going down
It is equivalent to:
-6 + (-8)
Answer:
Step-by-step explanation:
To the evaluate -5.3+7.9
We get
2.6
Therefore the error
=2.6-2.4
=0.2
2.64 divided by 6 equals 0.44. one ounce costs 44 cents
