Given cos x=0.4762,find the degree measure of x.round your answer to the nearest tenth

1 answer:

5 0

If you have a calculator, you can use the inverse cos " cos⁻¹ " key. Many upper level books write that as Arccos so as not to confuse you with a negative exponent. We do that because if you take the cosine of any angle, and then the inverse cosine of any angle, it leads you back to the original angle. Think of it as a big "UNDO" button.

To one decimal place, that result is 61.6 degrees.

I don't know how to simplify this question. Is quotient rule necessary?

barxatty [35]

Answer:

The answer to your question is $\frac{(x+1)^{2}(x - 23)}{(x-7)^{3}}$ , because the directions says to give the answer in factor form.

Step-by-step explanation:

$\frac{3(x+1)^{2}(x-7)^{2}- (x+1)^{3}(2)(x - 7)}{(x - 7)^{4}}$

Factor like terms (x - 7)(x + 1)²

$\frac{(x - 7)(x + 1)^{2}[3(x - 7) - 2(x + 1)}{(x - 7)^{4}}$

Simplify

$\frac{(x+1)^{2}[3(x - 7) - 2(x+1)]}{(x-7)^{3}}$

Expand

$\frac{(x+1)^{2}[3x - 21 -2x - 2]}{(x - 7)^{3}}$

Simplify

$\frac{(x + 1)^{2}(x - 23)}{(x - 7)^{3}}$

MArishka [77]

Answer:

218.7 lb.

Step-by-step explanation:

We have been given that the weight of male american between the ages 18 to 25 is normally distributed, with mean of 162.7 lb and a standard deviation of 28 lb.

One definition of obesity states that a person is obese if the z-score of his or her weight is greater than 2.

We will use z-score formula to solve our given problem.

$z=\frac{x-\mu}{\sigma}$ , where,
