Answer:
it's simple
Step-by-step explanation:
use the identity
1-cos²x = sin²x
Answer:
x = 96
Step-by-step explanation:
3/8x = 36
You have to multiply both sides of the equation by the inverse of the fraction to cancel it out.
(8/3)(3/8x) = (36)(8/3)
x = 96
If its a reflection across the y axis the x value is reflected and the y value stays the same, so (-3,7)

The probability that the written 3 digit number starts with 3 is 1/9
<h3>Explanation: </h3>
The total number of 3-digit numbers starting from 100 till 999, including both these endpoints, is 900. Since the first digit can be any number from 1 to 9; tens (second digit) and hundreds’ (third digit) can be any number from 0 to 9;( 9×10×10 = <u>900</u>). Therefore, three-digit numbers in between 100 and 999 = Total possible number of outcomes = 900.
For 3-digit number to start with 3, the first digit (hundreds’ place) has to be 3. The tens place (2nd digit) and units place can be any number from 0 to 9. Therefore, total number of favorable outcomes for the three digit number to start from 3 is 1×10×10 = <u>100</u> (numbers from 300 to 399)
Probability = Total number of favorable outcomes / Total possible outcomes = 100/900 = 1/9
