Step-by-step explanation:

Answer:

[tex]\displaystyle x=\left\{\frac{\pi}{6}+2n\pi, \frac{5\pi}{6}+2n\pi, \frac{3\pi}{2}+2n\pi\right\}, n\in\mathbb{Z}[/tex]

Step-by-step explanation:

We are given the equation:

[tex]2\cos^2(x)=\sin(x)+1[/tex]

And we want to find all solutions for x.

First, we should put the equation into terms of only one trigonometric ratio.

Since we are given cos²(x), we can turn this into sine. Recall the Pythagorean Identity which states:

[tex]\sin^2(x)+\cos^2(x)=1[/tex]

Therefore:

[tex]\cos^2(x)=1-\sin^2(x)[/tex]

By substitution:

[tex]2(1-\sin^2(x))=\sin(x)+1[/tex]

Distribute:

[tex]2-2\sin^2(x)=\sin(x)+1[/tex]

Isolate the equation:

[tex]2\sin^2(x)+\sin(x)-1=0[/tex]

We can factor:

[tex](2\sin(x)-1)(\sin(x)+1)=0[/tex]

Zero Product Property:

[tex]2\sin(x)-1=0\text{ or } \sin(x)+1=0[/tex]

Solve for each case:

[tex]\displaystyle \sin(x)=\frac{1}{2}\text{ or } \sin(x)=-1[/tex]

We can use the unit circle.

sin(x) = 1/2 for every π/6 and 5π/6. So, it will continue every 2π.

sin(x) = -1 every 3π/2. And this will also continue every 2π.

Hence, our solutions are:

[tex]\displaystyle x=\left\{\frac{\pi}{6}+2n\pi, \frac{5\pi}{6}+2n\pi, \frac{3\pi}{2}+2n\pi\right\}, n\in\mathbb{Z}[/tex]

Note:

If you only need the solutions within the interval [0, 2π), then it is:

[tex]\displaystyle x=\left\{\frac{\pi}{6}, \frac{5\pi}{6}, \frac{3\pi}{2}\right\}[/tex]

Answer:

Step-by-step explanation:

The length of the arc of the particle circle is equal to  23.55 units

The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.

Given here the radius of the circle as 5 units thus the length of the arc which makes an angle of π-π/2=3π/2 is angle subtended at the centre times the radius of the circle

Arc length = 5×3π/2

                  = 15π/2

                  = 15×3.14 /2

                  = 23.55 units

Hence The length of the arc of the particle circle is equal to  23.55 units

Step-by-step explanation:

if the perimeter is 100 than 20+20+x+x=100.

20+20=40

100-40=60

since there are two length sides, divide 60 by two and then you have your answer.

20+20+30+30=100

Answer: 0.75

Step-by-step explanation:

3.75/5 = 0.75$

Answer: So we'll use trig to solve this because it's a right triangle. The hypotenuse is the ladder (h) and the two smaller sides are the ground and the vertical wall (w).

That angle ladder makes with the ground = €

SOH: sin € = opposite/hypotenuse

No the ladder won't be safe!!!

Now let's make it safe:

The ladder's length (w) is constant, so stays 12

So now let's ask in an inequality what height will be safe (75° or less)

what does that mean?? well as long as you put the ladder against the wall so that the height from ground to top of the ladder is < 11.6 ft!!

Answer:

Step-by-step explanation:

Point( -4 , 1)  ; slope = m = 5

Point-slope form:

y - y1 = m(x -x1)

y - 1 = 5(x - [-4])

y - 1 = 5(x + 4)

y - 1 = 5x + 5*4

y - 1 = 5x + 20

    y = 5x + 20 + 1

   y= 5x + 21

Given:

The two sides of a triangle are 2 and 6.

To find:

The side length that would NOT work to make a triangle with the two slide lengths of 2 and 6.

Solution:

For a triangle, the sum of two smaller sides must be greater than the largest side.

Let x be the third side.

Case 1: x is the largest side, then

[tex]2+6>x[/tex]

[tex]8>x[/tex]              ...(i)

Case 2: x is not the largest side, then

[tex]2+x>6[/tex]

[tex]x>6-2[/tex]

[tex]x>4[/tex]              ...(ii)

From (i) and (ii), we get

[tex]4<x<8[/tex]

Here, 4 and 8 are not included.

6, 5, 7 are included in the above interval, but 4 is not included in the above interval. It means 4 would NOT work to make a triangle with the two slide lengths of 2 and 6.

Therefore, the correct option is D.
