Answer:
The system has an infinite set of solutions 
Step-by-step explanation:
From the first equation:
Replacing on the second equation:
This means that the system has an infinite number of solutions, considering:
The system has an infinite set of solutions
3∅ can be rewritten as (2∅+∅)
sin(3∅) = sin(2∅ + ∅<span>)
Opening brackets on the right hand side;
= sin2</span>∅ cos ∅ + cos2∅sin<span>∅
</span><span>This simplifies to;
= 2sin</span>∅cos^2∅ + sin∅ (1- 2sin^2∅<span>)
= sin</span>∅ (2cos^2∅ + 1 - 2sin^2∅<span>)
= sin</span>∅ (2(1 - sin^2∅) +1-2sin^2∅<span>)
= 3sin</span>∅ - 4sin^3<span>∅</span>
Answer: f(-4) = 17
Step-by-step explanation: Substitute (-4) for x.
- f(-4) = -5(-4) - 3
- f(-4) = 20 - 3
- f(-4) = 17
The experimental probability can be represented as a fraction of the number of times a five was not the result over the total number of times the cube was rolled.
The answer would be 288/350 or 144/175.
