Answer:
The correct answer is A
Step-by-step explanation:
We want to determine the decimal equivalence of .
We perform the long division as shown in the attachment.
Note that in carry out the long division, the denominator which is 3, will be outside the long division sign, while the numerator which is , will be inside the long division sign.
We see that the quotient of our long division is .
We can rewrite this as
Therefore .
Answer:
3/5
Step-by-step explanation:
Using SOHCAHTOA, we know that cos Ф =

Answer:
6.34 seconds.
Step-by-step explanation:
The object will hit the ground when h = 0.
-16t^2 + 90t + 72 = 0
8t^2 - 45t - 36 = 0
We can then use the quadratic formula to solve.
[please ignore the A-hat; that is a bug]
=
=
=
(45 - 56.36488268) / 16 = -0.7103051678
(45 + 56.36488268) / 16 = 6.335305168
Since the time cannot be negative, the object will hit the ground after about 6.34 seconds.
Hope this helps!
