Let , −5−6 be a point on the terminal side of θ . find the exact values of cosθ , cscθ , and tanθ .

gizmo_the_mogwai [7]

Given that point (-5, -6) is a point on the terminal side of θ. Since both the x coordinate and the y-coordinate are negative, θ is in the third quadrant.

The side opposite θ is -6 and the side adjacent θ is -5.

The hypothenus is given by $\sqrt{(-6)^+(-5)^2}=\sqrt{36+25}=\sqrt{61}$

The exact value of cosθ is given by:

$\cos\theta= \frac{adjacent}{hypothenuse} = \frac{-5}{\sqrt{61}}$

The exact value of cscθ is given by:

$\csc\theta= \frac{hypothenuse}{opposite} = \frac{\sqrt{61}}{-6}$ 

The exact value of tanθ is given by:

$\tan\theta= \frac{opposite}{adjacent} = \frac{-6}{-5} =1.2$

the cost of a phone call is c pence which is calculated using the formula c=20+5m where m is the number of minutes the phone cal

OLga [1]

I believe the answer is 25 because it says that 2)m=5 or it may be 30 because 5times 2 equals 10 and 10plus 20 gives you 30

I need to know how to do a)^

riadik2000 [5.3K]

he charges a fixed cost of $12, meaning a one-time charge of 12 bucks, plus 1.50 for each window.

1 window................ 12 + 1.5(1)

2 windows............. 12 + 1.5(2)

3 windows............. 12 + 1.5(3)

4 windows............. 12 + 1.5(4)

x windows............. 12 + 1.5(x)

$\bf \stackrel{cost}{y}=\stackrel{\stackrel{fixed}{cost}}{12}+\stackrel{\stackrel{per}{window}}{1.5x}$

$\bf \stackrel{cost}{28.50}=\stackrel{\stackrel{fixed}{cost}}{12}+\stackrel{\stackrel{per}{window}}{1.5x}\implies 16.50=1.5x\implies \cfrac{16.50}{1.5}\implies \boxed{11=x}$
