Answer:
D. {(2,3) (2,5) (4,7)}
Step-by-step explanation:
2 has an output od 3 and 5, and 4 has an output of 7
Answer:
Ф = 
Step-by-step explanation:
It is a bit difficult to input the work here, so I uploaded an image
- First we can use the trig identities to change sec²(Ф) to tan²(Ф) + 1
- Then we can combine like terms
- Then we can factor this as a polynomial function
- Then we can set each term equal to zero and solve for Ф
- The first term tan(Ф) - 2 = 0 has no solution because tan(Ф) ≠ -2 anywhere
- The second term tan(Ф) - 1 = 0 has two solutions of
and
so these are the solutions to the problem
62.92 meters, 63.37 meters, 63.7 meters
Only one. These problems always have one solution unless something has changed.
