Answer:
x = 47.5
Step-by-step explanation:
5 times 5 = 25
9 times 5 = 45
45 divided by 2 = 22.5
25 + 22.5 = x
x = 47.5

6 tan(2x) − 6 cot(x) = 0 ; [0, 2π)
9514 1404 393
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

Find the area of the circle that contains the sector described below. Round to the nearest tenth, if necessary.
One sector has an area of 325 square millimeters and an arc measure of 72°.
__ mm2
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.
What is Circle?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:
Slope = 2
Step-by-step explanation:
To get the slope of the line first choose two points on the graph,
Let the points be (0, 0) and (1, 2).
Rise of the line between these points = 2 units (arrow pointing upwards)
Rise of the line will be positive when arrow is upwards and it will be negative when pointing downwards.
Rise = 2
Similarly, run = 1 (arrow pointing right)
Run of a line will be positive when it points to the right and negative when points to the left.
By this rule, Slope = [tex]\frac{\text{Rise}}{\Text{Run}}[/tex]
Slope = [tex]\frac{2}{1}[/tex]
= 2
Therefore, slope of the line is 2.
