The statement makes sense because litters per second is a unit of speed
Answer:
that would also be car 1, because in a rotation like that its like you do a spin and come back to the same position, that is a 360 rotation.
Answer:
9x2+5x
Step-by-step explanation:
combine like terms
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
