Answer:

  x ∈ {π/6, π/2, 5π/6, 7π/6, 3π/2, 11π/6}

Step-by-step explanation:

We can divide by 6 and use some identities to rewrite this as ...

  2tan(x)/(1-tan(x)²) -1/tan(x) = 0

  2tan(x)² -(1 -tan(x)²) = 0 . . . . . . . . . multiply* by tan(x)(1 -tan(x)²)

  3tan(x)² = 1

  tan(x) = ±1/√3   ⇒   x = {π/6, 5π/6, 7π/6, 11π/6}

__

Interestingly, if we use different identities, we can rewrite it as ...

  2cot(x)/(cot(x)² -1) -cot(x) = 0

  cot(x)(3 -cot(x)²) = 0 . . . . . . . multiply by (cot(x)² -1)

In addition to the zeros found above, this equation also has solutions where cot(x) = 0. That is ...

  x = {π/2, 3π/2}

_____

Usually, the first method shown would give all the solutions. Fortunately, we had a graph of the function, so we could see that the first set of solutions found was not complete. (This is one reason I like to use a graphing calculator for guidance on problems like this.)

_____

* In the first solution, we multiplied by the denominator tan(x)(1 -tan(x)²). It was multiplying by tan(x) that made the π/2, 3π/2 solutions disappear. Had we kept 1/tan(x) as a numerator factor of cot(x), we would have had the same result as seen in the second approach.

Answer:

x = 8√3

Step-by-step explanation:

Using the Pythagorean Theorem:

a² + b² = c²

x² + 8² = 16²

x² + 64 = 256

x² = 192

√x² = √192

x = √64 √3

x = 8√3

Answer:

43.98

Step-by-step explanation:

The formula for circumference is 2(pi)r

R is the radius

The radius is 7

So that means 2(pi)(7) is the answer

2(pi)(7) = 43.98

If One sector has an area of 325 square millimeters and an arc measure of 72° then the area of circle is 1625 square mm.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

To find the area of circle we have to know the radius of the circle.

We know Area of sector=(θ/360º) × πr²

325=72/360×3.14r²

325=0.2×3.14r²

325=0.628r²

Divide both sides by 0.628

r²=517.51

Area of circle= πr²

=3.14×517.51

=1625 square mm.

Hence, if One sector has an area of 325 square millimeters and an arc measure of 72° then the area of circle is 1625 square mm.

Answer:

5.2 hours or 312 minutes

Step-by-step explanation:

The plane route has been given as 260 miles.

We're told that the car/road rouge is 10% longer, and that is 260 * 1.1, which is equal to 286 miles.

Now, the car travels at 55 miles per hour, and we're to calculate how long it will take to travel.

Speed = distance / time

Making time the subject of formula, we know that

Time = distance / speed

Time = 286 miles / 55 miles per hour

Time = 5.2 hours, converting to minute, we have 5.2 * 60 = 312 minutes.

Answer:

56

Step-by-step explanation:

the length of the missing side is 7

so 7 x 8 = 56

To find the missing side:

You must add 8 + 8 = 16

Subtract 16 from the total perimeter = 14.

Divide 14 by 2 = 7 you divide by two since there are two missing lengths and when you add them they have to equal to 14.
