D^2y/dx^2+4dy/dx-12y=cos2x

1 answer:

3 0

If you're solving for x, you'd move all the terms containing x to the left side of the equation:

d^2y/dx^2+4y/x-12y-cos^2(x)+sin^2(x)=0

If you're solving for y, you'd simplify both sides of the equation, then isolating the variable:

y=xcos(2x)

Answer:

$g(x)=\sqrt[3]{x-3}+4$

Step-by-step explanation:

The function g(x) is a shifted version of the function f(x); f(x) is shifted by 3 along x-axis and by 4 along y-axis.

Another way of thinking about this is that the function g(x) contains points (3, 4); therefore,

$g(x)=\sqrt[3]{x-3}+4$

which goes through the point (3, 4).

Answer:

APR = 416%

EAR = 5370.60%

Step-by-step explanation:

Given:

Interest rate = 7.8% per week

Now,

In an year there are total 52 weeks

thus,

The APR (Annual percentage rate) = Interest rate × Total weeks in an year

APR = 8% × 52

APR = 416%

and, EAR ( Effective Annual Rate ) = ( 1 + r )ⁿ - 1

Here,

r is the interest rate per week

n is the total weeks in an year

thus,

EAR ( Effective Annual Rate ) = ( 1 + 8% )⁵² - 1

= ( 1 + 0.08 )⁵² - 1

= 53.7060

53.7060 × 100% = 5370.60%
