Which equation is correct?

nikdorinn [45]

Answer:

D) arccsc (x) = arcsin (1/x)

Step-by-step explanation:

Here's how you can prove it: Consider a right triangle with hypotenuse 1 and a side length 1/x. If θ is the angle opposite of 1/x, then:

sin θ = 1/x

and

csc θ = x

Solving for θ:

θ = arcsin (1/x)

θ = arccsc (x)

Therefore:

arccsc (x) = arcsin (1/x)

Calculate the following scenario for a simple interest loan.

Semenov [28]

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. The amount of monthly payments is $287.5.

<h3>What is simple interest?</h3>

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,

SI = (PRT)/100

where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.

Given the following details about the simple interest loan as,

Principal amount, P = $3,000

Interest rate, r = 15%

Number of instalments = 12

Since there are 12 instalments each for a month, therefore, the time period for which the loan was there is 1 year.

Now, the interest for 1 year will be,

Interest amount = ($3,000 × 1 × 15)/100

= $450

Further, the total amount that is needed to be paid back is the sum of the principal amount and Interest amount.

Amount needed = $3,000 + $450

= $3,450

Moreover, there are 12 instalments, therefore, the number of monthly payments will be,

Monthly payment = $3,450/12 = $287.5

Hence, the amount of monthly payments is $287.5.

You would need to multiply the monthly cost, $14, by the number of months and then that would be added to the cost to join, $25

For 6 months it would cost 14 x 6 = 84 + 25 = $109

The answer would be C.

what is the answer to Graph the function. f(x)=cos(x)−3 Use 3.14 for π i need it now im struggling on this test

kvv77 [185]

Answer:

we can draw the graph of cosine with amplitude 2.

Step-by-step explanation:

In the given function g(x) = 2cosx we know the following parameters which are helpful to draw the graph.

Its a cosine graph given in the form of y = acos(Bx + c) + d

Here a is amplitude, period = , c = phase shift, d = vertical shift

We know a = 2, B = , c = 0, d = 0.

What is the product of the complex number z1 and it’s conjugate? PLEASE HELP GRAPH in picture

12345 [234]

Answer:

The product is 25

Step-by-step explanation:

we know that

The complex number z1 is equal to

z1=(-4-3i)

we know that

To find the complex conjugate of (-4 - 3i) we change the sign of the imaginary part

The conjugate is equal to (-4+3i)

therefore

$(-4-3i)(-4+3i)=16-9(-1)=25$
