Help me, its trigonometry college
prohojiy [21]

4) (a) For these problems, you should take time to familiarize yourself with common fractions that appear on the unit circle.  \frac{\sqrt{3}} {3} does not appear in the unit circle unless you take the quotient 1/2 divided by sqrt(3)/2 which gives you 1/sqrt(3) which is the same as sqrt(3)/3.  So our numerator is 1/2 and our denominator is sqrt(3)/2.

And remember tangent is just sin/cos.  So what degree has sinx as 1/2 and and cosx as sqrt(3)/2?  Well, 30 degrees does, but 30 degrees is not within the range we are given.  That means they are looking for a sinx that gives us -1/2 and a cosx that gives us -sqrt(3)/2 and that is 210 degrees.

And 210 degrees in radians is 7pi/6.

I hoped that made sense.

(b) This is a lot easier. What angle gives us a cos x of -sqrt(3)/2?  According to the unit circle, 150 degrees and 210 degrees does.  They usually want these in radians, so the answer is 5pi/6 and 7pi/6, respectively.

5) What quadrant is radian measure 5 in?

Well 2pi or roughly 6.28 is a full circle. And 5 is slightly less than 6.28, so it is probably in quadrant IV.

But to be sure let's change 5 radian to degrees:

5 * 180/pi = 900/pi = 286.48 degrees

286.48 degrees is definitely in Q4, so we are correct.

Jen wants to have 8 rose bushes planted on her property. She asked a landscaping company to give her a bid. The contractor wante
Stella [2.4K]

Answer:

Jen saved $320.

Step-by-step explanation:

Since she would like 8 bushes total and 1 = $60, we will multiply (60 x 8) to get a total of $480.

Finally, to find out how much Jen saved, we must subtract Jens final priced total ($480) - the landscapers asking price ($800) to get ( = $320)

Jen payed $480 and saved $320.

Hope this helps...

Use the distance formula to find the distance between each PowerPoint round to the nearest 10th if necessary
natita [175]

Answer:

Step-by-step explanation:

Distance between two points (x_1,y_1) and (x_2,y_2) is given by the formula,

Distance = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}

a). A(-6, -4), B(-3, -1)

Distance between A and B = \sqrt{(-6+3)^2+(-4+1)^2}

                                             = \sqrt{9+9}

                                             = 3√2

                                             = 4.2 units

b). C(3.5, 1), D(-4, 2.5)

Distance between C and D = \sqrt{(3.5+4)^2+(1-2.5)^2}

                                              = \sqrt{58.5}

                                              = 7.65

                                              ≈ 7.7 units

c). Distance between X(5, -5) and Y(-5, 5)

    Distance = \sqrt{(5+5)^2+(-5-5)^2}

                    = \sqrt{200}

                    = 10√2

                    = 14.14

                    ≈ 14.1 units
