What is a trigonometric function?

The fundamental 6 functions of **trigonometry **have a range of numbers as their result and a domain input value that is the angle of a right triangle.

The trigonometric function is very good and useful in **real**-**life **problems related to the right-angle triangle.

As per the given **trigonometric **equation,

cos(x)cosπ/2 + sin(x)sinπ/2 = √3/2

Since, cosπ/2 = 0 and sinπ/2 = 1

cos(x)(0)+ sin(x)(1) = √3/2

sinx = √3/2

sinx = sin π/3 = sin 2π/3.

Hence "The **value **of cos(π/2) is 0 sinπ/2 is 1 **further **sinx = √3/2 thus x = π/3,2π/3".

Mr. Borden was given a $50 gift card to use at the bowling alley. It costs him $10 per night to bowl. Each time he goes to the bowling alley he records the amount he has used and the amount he has left. If x is the number of nights bowled, b(x) is the balance on the gift card. Discreet

### Answers

**Answer:**

He initially has $50 on his card.

For each night that he goes to play, $10 are discounted from the card, then if he went x nights to play, the amount of money that there is in the card is:

b(x) = $50 - $10*x

Now, notice that x must be a whole number because this measures the number of nights that he went to play, and we can not have rational numbers to describe this.

Then the domain of this function will be discrete (and this implies that the range must also be discrete)

Where the possible values of x are:

{0, 1, 2, 3, 4, 5}

(after x = 5, there is no more money in the card)

And the possible values of b(x) are:

{$0, $10, $20, $30, $40, $50}

**Answer:**

cotx - cot2ⁿx

**Step-by-step explanation:**

*Note: finding the sum not x*

First rewrite the first term as:

1/sin2x = sinx / (sinxsin2x) = sin(2x-x) / (sinxsin2x) =(sin2xcosx - cosxsinx) / (sinxsin2x) = (sin2xcosx)/(sinxsin2x) - (cos2xsinx)/(sinxsin2x) =cosx/sinx - cos2x/sin2x =cotx - cot2x

### Answers

**Answer: 31.18**

**Step-by-step explanation:**

The problem is focused on mainly the right triangle made up of points M, Q, and R. This problem can be solved with the base formula, *b* = *a* · tan(β) where *a* = the length of line MR, β = m∠MQR, and *b* is the unknown length of RQ.

Given:

RQ = 18 · tan(60°)

Point M is the midpoint of line PM and line MR. Since MP is equal to 18, MR has to be 18 as well. This means that the value of *a* is 18.

The vertex of ∠MQR is Q, which is 60°.

Step 1: Find the tangent of 60°

The tangent of 60° is √3

Step 2: Solve

RQ = 18 · √3

18 · √3 = 31.18

RQ is equal to 31.18

**Answer:**

<XYZ = 83

**Step-by-step explanation:**

we can see that the line XY is tangent to point Y

we can also the see that <XYZ intersects the line that forms arc 166

when a tangent line intersect the line that forms an arc, the angle formed by the tangent will be equal to half of the arc

so in other words angle XYZ is 0.5 of Arc 166

so <XYZ = 83

The **x-coordinate** of the solution to the **system of equations** is 3.

What is a **system of equations**?

A **system of equations** is a set or collection of two or more equations with the same variables. The common solutions are the** intersecting points** of the equations. The number of equations and unknowns affects the existence and uniqueness of the **solution**. A system of **equations** can be classified similarly to single equations.

Given that, the graph given shows a system of **equations**,

We know that, the solution of the system of **equations**, is given by the point where the lines intersect,

So, here the lines intersect, at (3, 2)

Therefore, the x-coordinate is 3

Hence, the **x-coordinate** of the solution to the **system of equations** is 3.

The value of a new car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was x dollars?

### Answers

**Answer:**

The value of the car will be** x - (0.15)x** after a year.

**Step-by-step explanation:**

The car was 15% more when it first came out, and the price went down by 15% after a year.

Therefore, to solve this problem, we need to multiply 0.15 by the initial cost, which will tell you how much the car price decreased.

Then, we need to subtract this amount from x, or the initial cost, in order to find how much the car will be worth after a year.

Therefore, the value of the car will be **x - (0.15)x** after a year.
