Answer:
-4.1
Step-by-step explanation:
If x = 0.4, then simply subtract 4.5 from 0.4.
0.4 - 4.5 = -4.1
Ok i tried by best

Answer:
cos Ф = adj / hyp could be either 4/5 or -4/5.
Step-by-step explanation:
If sin Ф = 3/5, then we can assume that the opposite side is 3 and the hypotenuse is 5. Using the Pythagorean Theorem, we find that the adjacent side is 4:
√(5² - 3²) = √16 = ±4.
cos Ф = adj / hyp could be either 4/5 or -4/5.
Answer:
2-[1, 2]
Step-by-step explanation:
From the graph, we can conclude the following things:
1. The graph is of degree 4 as it intersects the x axis at 4 points.
2. The graph tends to infinity for increasing the value of 'x' along positive or negative x-axis.
3. The graph has 3 turning points between the intervals [-1, 0], [1, 2] and [2, 3]
4. Local maximum: The top of mountain of the graph represents local maximum. So, during the interval [1, 2], there is a local maximum.
5. Local minimum: The lowest point or the valley of the graph represents local minimum.
So, during the intervals [-1, 0] and [2, 3], there are local minimums.
Thus, there is only one local maximum during the interval [1, 2].
