V . w = 6(-7) + 7(5) + (-3)(2) = -42 + 35 - 6 = -13
Answer:
Step-by-step explanation:
Sin A = ![\frac{opposite side}{hypotenuse}=\frac{5}{13}\\\\](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%20side%7D%7Bhypotenuse%7D%3D%5Cfrac%7B5%7D%7B13%7D%5C%5C%5C%5C)
Cos A = ![\frac{Adjacent side}{hypotenuse}=\frac{12}{13}](https://tex.z-dn.net/?f=%5Cfrac%7BAdjacent%20side%7D%7Bhypotenuse%7D%3D%5Cfrac%7B12%7D%7B13%7D)
Tan A = ![\frac{opposite side}{adjacent side}=\frac{5}{12}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%20side%7D%7Badjacent%20side%7D%3D%5Cfrac%7B5%7D%7B12%7D)
A = tan⁻¹ (5/12) = 22.61°
Answer:
Got You homie
Step-by-step explanation: ok so what you wanna do is take 2 and multiply it by itself and divide it over 2.. That should equal 84 I think.
Answer:
(A) Because event B rules out obese subjects.
Step-by-step explanation:
(A) is correct because B doesn't have obese people
(B) is incorrect because we don't know if there are obese person but not overweight.
(C) states a correct fact but that portion doesn't relate to event B (overweight but not obese)
Similarly, (D) also states a correct fact but doesn't relate to event B (overweight but not obese)
In general you can multiply through by the LCD
For example solve :-
2/x + 1 / (1+ x) = 11/12
The LCD is 12x(x + 1).
Now we multiply each term by 12x(x + 1)
2*12(x+1) + 12x = 11x(x + 1)
and this is solved in the usual way.
