pls help! evaluate the sine of the real number, pls give exact answers

Answer:

Neither

Step-by-step explanation:

To determine if two lines are parallel or perpendicular, you have to look at the slopes. For the line y=kx+b, k is the slope.

For two lines  y=k1x+b1 and y=k2X+b2 ,When K1=K2, two lines are parallel; when K1=-1/k2, two lines are perpendicular. It doesn't matter whatever b1, b2 are. Hence to save time, you only need to calculate  k1 and k2.

To calculate the slope k of any line, you have to change the equation to y=kx+b

For -y=3x-2, k=3/(-1)=-3 (you divide -1 on each side of =, but you don't need to calculate -2/(-1))

For -6X+2y=6, K=6/2=3 (you first move the -6x to right side, it becomes 6x, then divide by 2)

Now you can get the answer: The two lines neither parallel nor perpendicular

To determine how the graph of the parent function [tex]y = x^2[/tex] is transformed to create the graph of the new function [tex]y = -(x – 1)^2 – 5[/tex], we need to analyze the individual transformations one by one Therefore the correct option is A.

1. Translation: (x – 1) This term inside the function represents a horizontal translation of the graph. When we subtract 1 from x, the entire graph is shifted to the right by 1 unit. Hence, this function is translated right 1 unit. 2. Reflection: (-) The negative sign outside the function reflects the graph across the x-axis. Thus, the graph opens downward.

3. Vertical Transformation: -5 The term -5 outside the function causes a vertical shift of the graph downward by 5 units. In summary, the graph of the new function [tex]y = -(x – 1)^2 – 5[/tex]  undergoes the following transformations: - Translated right 1 unit due to (x – 1) - Reflected (opens downward) due to the negative sign - Translated down 5 units due to -5 Therefore, the correct answer is A. Translated right 1 and down 5 only

Hence the correct option is A

On the first day the company is giving Rs124, 000.

On the fifteenth day the company will give Rs 125400

The amount they wanted to give in august for promotion is Rs 124,000. They increased the amount each day by Rs 100.

Therefore, the sequence will be as follows;

124,000, 124,100, 124,200 .......

i.

The amount they will give on the first day is Rs124, 000

ii

The sequence is increasing by 100. Therefore,

common difference = 100

first term = 124, 000

Therefore,

a₁₅ = 124000 + (15 - 1)100

a₁₅ = 124000 + 1400

a₁₅ = 125400

Answer:

y = 8sqr3,

x = 4sqr3

Step-by-step explanation:

Use SOH CAH TOA, to solve this.

Here I know the opposite, so I could use either SOH either TOA or both to find the 2 unknowns.

To find y, I would use SOH, which is Sin(angle) = opposite/hypotenuse.

When I rearrange it, I get opposite/Sin(angle) = hypotenuse.

Now let's fill in with the values to give:

12/sin(60) = 8sqr3

And then to find x, let's use TOA, which is Tan(angle) = opposite/adjacent.

Rearrange it to get opposite/Tan(angle) = adjacent. This gives us a side x with a value of:

12/tan(60) = 4sqr3

Answer: Height = 16.6 ft

Step-by-step explanation:

The area of a trapezoid is (b1+b2)*h/2, where b1 and b2 are the bases and h is the height.

We can plug in the values given:

234.06 ft^2 = (19.2 ft + 9 ft)*h/2

We can multiply both sides by 2 and combine like terms:

468.12 ft^2 = 28.2 ft*h

Divide both sides by 28.2 ft:

Height = 16.6 ft

Before we solve for each angle, let's find the bottom left angle of the triangle.

We know that:

This means that:

Step-by step calculations:

⇒ 106 + x = 180

⇒ 106 - 106 + x = 180 - 106

⇒ x = ∠BCA = 74°

We know that:

⇒ Sum of the interior angles of the triangle: 180°

This means that:

⇒ (74) + (3y + 22) + (4y) = 180

Step-by step calculations:

⇒ (74) + (3y + 22) + (4y) = 180

⇒ 96 + 7y = 180

⇒ 96 - 96 + 7y = 180 - 96

⇒ 7y = 84

⇒ 7y/7 = 84/7

⇒ y = 12

Step-by step calculations:

⇒ ∠B = 3y + 22

⇒ ∠B = 3(12) + 22

⇒ ∠B = 36 + 22

⇒ ∠B = 58°

-------------------------------------

⇒ ∠A = 4y

⇒ ∠A = 4(12)

⇒ ∠A = 48°
