Answer:
Step-by-step explanation:
Before adding we require the fractions to have a common denominator
The lowest common denominator of 2, 5 and 3 is 30, thus
+ 
+ 
= 
+ 
+ 
Add the numerators leaving the denominator
= 
=
I don't know if this is the answer that you are looking for, but would the answer be all solutions?
Answer:
- 
Step-by-step explanation:
Evaluate cosπ then inverse tan, that is
cosπ = - 1
(- 1) = -
To simplify most teachers prefer to round to tenth or hundreth
best answers: 0.9, 0.87
5. To figure this out you must find when y = 0
-16t^2 = -200
t^2 = 12.5
Square root
t = 3.54 C
6.
Axis of symetry = -.5 (always a vertical line down vertex)
Vertex = (-.5, -6.5) (the minimum of the graph)
B
7. To find maximum height you must find the vertex
The maximum height is 549 feet after 5.75 seconds
C
9. Solve for X
x^2 = 1
Square root
X = plus or minus 1
A
