Answer:
x = 25
Step-by-step explanation:
Given:
Amount invest p = Tk.x
Number of year t = 4
Rate r = x%
Profit = Tk.x
Find:
Value of x
Computation:
Profit = prt / 100
Tk.x = [(Tk.x)(x)(4)] / 100
x = 100 / 4
x = 25
Answer:
im probably wrong but maybe the percentage or ratio
Step-by-step explanation:
The answer is

. I've demonstrated the 'split and combine' method in the image attached.
This principal is based on the fact that you can multiply and divide radicals as you would with regular integers, but you remember that the answers remain as radicals unless the number you're dealing with is a square (e.g. 9, 16, 25).
Answer: The function could be y= - 3 cos x
Solution:
One x-intercept is (pi/2,0): We can use a trigonometric function like cosine that has x-intercept (pi/2,0).
The domain of the cosine function is the set of all real numbers.
The maximum value is 3, then the amplitude must be 3: y = 3 cos x
The y-intercept is (0,-3) then it is the functio y = 3 cos x, reflected around the x-axis: y = - 3 cos x
