Answer:
2 i believe
Step-by-step explanation:
Firstly, we will let this mystery number we are finding be labelled as x. Double this number can be written as 2x. 5 less than double this number is written as 2x - 5. And because this number is between -7 and 13, we have the full inequality, -7 < 2x - 5 < 13.
To solve this inequality, we want to isolate x, so we add 5 to all 3 parts of the inequality. Doing so cancels out the - 5 in the middle, so our new inequality is -2 < 2x < 18. Now we want to divide all 3 parts of the inequality by 2 to isolate x, so now our final inequality is -1 < x < 9. Thus, we can say that x is between -1 and 9.
When x = 1, y = 1 + 4 = 5
When x = 3, y = 3 + 4 = 7
When x = 5, y = 5 + 4 = 9
When x = 7, y = 7 + 4 = 11
Therefore, the correct answer is option D.
Use sin(45)= 5sqrt2/x
Then you would multiply x to sin(45) then divide sin(45) by 5sqrt2
and you would get
10 for M
You would then use Pythagorean theorem and get
3sqrt 10
