Need help in these 2 last questions!!!

Question 9

The point (30,15) means that x = 30 and y = 15 pair up together.

Similarly, (40,25) means we have x = 40 and y = 25 paired up.

Apply the slope formula to get

m = (y2-y1)/(x2-x1)

m = (25-15)/(40-30)

m = 10/10

m = 1

The slope is 1.

It tells us that each time y goes up by 1, x is also increasing by 1.

slope = rise/run = 1/1

rise = 1, run = 1

The rise is the change in y, the run is the change in x.

This means the plant's height (y) goes up by 1 cm each time the number of days (x) goes up by 1.

In short, the plant's height is increasing by 1 cm per day

========================================================

Question 10

y varies directly with x, so y = kx for some constant k.

We're then told that x = -1 and y = -2 pair up together.

Let's find k based on those items

y = kx

y/x = k

k = y/x

k = -2/(-1)

k = 2

So y = kx becomes y = 2x

Then we're asked to find x when y = -4

y = 2x

y/2 = x

x = y/2

x = -4/2

x = -2

Angle θ is in standard position and (−6,−3) is a point on the terminal side of θ. What is the exact value of csc θ in simplest f

bearhunter [10]

Answer:

$\displaystyle \csc\theta=-\frac{\sqrt{5}}{2}$

Step-by-step explanation:

Since $\displaystyle \csc\theta=\frac{1}{\sin\theta}=\frac{1}{\frac{\text{Opposite}}{\text{Hypotenuse}}}=\frac{\text{Hypotenuse}}{\text{Opposite}}$ , we need to find the hypotenuse given our corresponding opposite and adjacent lengths of -6 and -3 accounting for Quadrant III:
