\frac{1}{ cos^{2}  \alpha  } +  \frac{1}{ sin^{2}  \alpha  } =  \frac{ sin^{2}  \alpha   +  cos^{2}  \alpha   }{ sin^{2}  \alpha *  cos^{2}  \alpha  } =  \frac{1}{sin^{2}  \alpha *  cos^{2}  \alpha}

Help me with this please
Reika [66]

Answer:

$2,459.21

Step-by-step explanation:

(see attached for reference)

recall that the formula for compound interest is:

A = P [ 1 + (r/n)^ (nt) ]

where,

A = Final amount ( we are asked to find this)

P = principal amount = given as $2,340

r = Annual Interest Rate = given as 5% = 0.05

n = number of times compounded in a year = 4 (compounded quarterly)

t= time = 1 year

Substituting the values into the equation,

A = P [ 1 + (r/n)^ (nt) ]

A = 2,340 [ 1 + (0.05/4)^ (4·1) ]

A = $2,459.21

When analyzing three linear functions, Michele noticed that they all intersected at the point (5, 3). What conclusion can Michel
qwelly [4]

Answer:

The linear function with the smallest slope must be multiple of one of the other two linear functions if all functions are coplanar. Otherwise, they intersect at the given point in space.

Step-by-step explanation:

A system of two linear functions with two variables have an unique solution on a given plane, as there are three linear function, it means that linear function with the smallest slope must be multiple of one of the other two linear functions.

But, if those functions are not all coplanar and have 3 variables, they intersect at the given point.
