Trigonometric functions: what is the value of x?

Mathematics
1 answer:
Airida [17]4 years ago
3 0

Answer:

x ≈ 19.7

Step-by-step explanation:

Using the sine ratio in the right triangle.

sin66° = \frac{opposite}{hypotenuse} = \frac{18}{x} ( multiply both sides by x )

x × sin66° = 18 ( divide both sides by sin66° )

x = \frac{18}{sin66} ≈ 19.7 ( to the nearest tenth )

13 cm<br> Diameter 6.4 cm<br> Find the volume to the nearest hundredth using<br> 3.14 instead of PI
AlekseyPX

Answer:

418.00 cm³

Step-by-step explanation:

The volume of a cylinder is given by πr²h (r being the radius and h being the height)

The radius is half of the diameter: 6.4/2 is 3.2.

The height shown here is 13.

Instead of pi, the question says to use 3.14 instead of pi.

Putting these all together, you get 3.14×(3.2)²×13.

This can be expanded to 3.14×10.24×13.

From there, multiplying it all together gives you 417.9968 cm³.

The problem says to the nearest hundredth, so you want to round it to 2 decimal places. Since the 6 is above 5, it gets rounded up, leaving you with 418.00 cm³.

The missing factor would be (n+2)... If you wanted to understand it, you simply solve 4n^2+9n+2 which gives you (4n+1)(n+2).

Zen rolled a fair six-sided die 12 times. The table below shows the number of times each number was rolled:
Sunny_sXe [5.5K]
4 was rolled 2 times
5 also 2 times
6 was rolled 4 times
So the result was greater than three eight times out of 12 rolls. 
P=8/12=2/3
