If cos theta = 0.3090, which of the following represents approximate values of sin thetha for 0 degrees <90 degrees? A. sin t
artcher [175]

In this question, the given value is

cos \theta = 0.3090

And we have to find the value of sin theta and tan theta where theta is in first quadrant .

And in first quadrant, all are positive .

Now we use the formula, which is

sin \theta = \sqrt{1-cos^2 \theta} = \sqrt{1 - 0.3090^2} = 0.9511

And tan theta is the ratio of sin theta and cos theta, that is

tan  \theta = \frac{sin \theta}{ cos \theta} = \frac{0.9511}{0.3090} =3.078

So the correct option is B .

Ann [662]
You can say : 15% ⇒ ? if 100% ⇒ 32.50 $ 
so next you can say : 15/100 = ?/32.50 ⇒ ? = (15/100) × 32.50 = 15 × 32.50 ÷ 100 = 4.875 ⇒ so the answer is 4.785 $ ;D i hope this will be helpful :))

Step-by-step explanation:

Range is left to right so that means that the only point on the x axsis you can plot is -6 and the domain is up and down so you cant plot a point below 5
