I assume you're allowed to use sin and cos laws here, this is a trigonometry class, yes? Here we have an angle of a right triangle, and the side adjacent to it, and we need to find the hypotenuse. Since cos = adj/hyp, it's the proper one to use here:
Evaluate it with a calculator to get x = 12.04 units. Make sense?
Answer:
fifth option
Step-by-step explanation:
Given
- 2(x - 5) ≤ 6x + 18 ← distribute left side
- 2x + 10 ≤ 6x + 18 ( subtract 6x from both sides )
- 8x + 10 ≤ 18 ( subtract 10 from both sides )
- 8x ≤ 8
Divide both sides by - 8, reversing the sign as a result of dividing by a negative quantity, thus
x ≥ - 1
Answer:
Check below for the answers and explanations.
Step-by-step explanation:
The number of samples or observations used in an experiment is the sample size.
The speaker here claims that he has seen at least a dozen people interviewed on TV who are fed up with celebrities giving political opinions. This means that his sample size is 12.
A sample size of twelve compared to the population of a country is not sufficient to arrive at a valid conclusion.
Response bias is the tendency of respondents to give accurate information to interviews or research questions.
The speaker cannot guarantee that the few people he has seen on the TV gave an accurate information about their feelings towards the attitudes of celebrities to politics.
For these reasons, this argument fails the strength test and is weak.
Answer:
The maximum value of N-M will be 792
Step-by-step explanation:
For N - M to be maximum
N must be very large and M must be very small
largest 3 numbers occur in 900's and smallest 3 digit numbers occur in 100's
so we need such an N which starts with 9 and ends with 1 so that on reversing it produces a number starting with 1.
If N = 901 , M will be 109
N - M = 792
This is the largest possible value of N - M
All other values of N-M will give a smaller value than 792.
-3/9 is equal to -0.3333333333333
So no, -3/9 is not greater than -0.33
Hope this helps ^-^
