Answer:
y = 3x
Step-by-step explanation:
Answer:
the gradient is the same= 4
the y intecept is different, one is positive 1 and the other is negative 3
Given:
Amount borrowed (P)= $25000
Rate of interest (r)= 6%
Time (t)= 4 years.
To find:
The total interest the company pay in all.
Solution:
We know that,
where, A is amount, P is principal, r is rate of interest and t is time period.
Now,
Therefore, the total interest is $6561.924.
F(x) = x - 2sinx
To find for what values of x graph has tangents we need to differentiate function f(x).
f'(x) = 1-2cosx
Now, if we want to have horizontal tangents we need to make function f'(x) equal to 0 because at minimum or maximum of function f(x) tangent is horizontal.
1-2cosx = 0
cosx = 1/2
x = pi/3 + 2*n*pi and
x = -pi/3 + 2*n*pi
Explanation: cosx = 1/2 for both 60° and -60°. If we make one circle cosx will be equal to 1/2 for 420 and 300 degrees. Writing degrees in radians (using pi) we can write formulas above where 2*pi represents one full circle and n is an integer which represents how many circles we made.
