lana66690 [7]

Answer:

C  Yes, 75+ 2.5*60 = 225

Step-by-step explanation:

The charges for the electrician

1st hour = 75

Additional hours 60

We have 3 1/2 hours of labor

The first hour is 75 dollars

3 1/2 - 1 = 2 1/2

There will be 2 1/2 hours at the 60 dollar rate

75 + 60 * 2.5 =

75 + 150

225

If sin theta = 2/3 and tan theta <0 what is the value of cos theta?
Mrac [35]

Answer:

d) \cos(\theta)=-\frac{\sqrt{5}}{3}

Step-by-step explanation:

If   \sin(\theta)=\frac{2}{3} and \tan(\theta)\:, then

\theta is in quadrant 2.

Recall that;

\sin^2(\theta)+\cos^2(\theta)=1

We substitute the given sine ratio to obtain;

(\frac{2}{3})^2+\cos^2(\theta)=1

\frac{4}{9}+\cos^2(\theta)=1

\cos^2(\theta)=1-\frac{4}{9}

\cos^2(\theta)=\frac{5}{9}

\cos(\theta)=\pm \sqrt{\frac{5}{9}}

\cos(\theta)=\pm \frac{\sqrt{5}}{3}

We are in the second quadrant, therefore

\cos(\theta)=-\frac{\sqrt{5}}{3}
