Answer:
No solution
Step-by-step explanation:
If you were to do elimination, both the x and the y would cancel out and get 0=1, which is not true. And if you were to do it as substitution, then it would still get an answer that doesn't make sense.
The end of its travel is when S(t)=0 or when it has hit the ground...
-16t^2+25=0 divide equation by -1
16t^2-25, this is a difference of squares which always factors:
(a^2+b^2)=(a+b)(a-b), in this case:
(4t+5)(4t-5)=0, since t>0
t=5/4=1.25, and since it started falling at t=0, its time moving in the air is:
1.25-0=1.25 seconds.
For the first one, simplify the radicals. The 3 root 8 can be rewritten as 3 root 4 root 2, which turns into 6 root 2. The 4 root 3 can’t be simplified, so just multiply. 6*4=24 and the root 2*root 3 turns into root 6. So your answer for the first one is 24 root 6.
For the next one you can’t have a radical in the denominator so just multiply by root 3/ root 3, which gives you 6 root 3/3 which simplifies into 2 root 3.
Domain: f (x) is the set of all values for which the function is defined
range: the set of all values that f takes
