Answer:

ok, first plot the point, 0, 4. that's your y intercept, it should be on the y axis. then count up one, then to the right four for your next point. the slope is 1/4, meaning that you rise 1 spot and move 4 spots. so your second point should be (4, 5) and your third point should be (6, 9) that's about it. if you need more help i can provide a better explanation

Answer:

x = 121°

Step-by-step explanation:

The angle supplementary to 115° is 180 - 115 = 65° and the angle that forms a full circle with 304° is 360 - 304 = 56°. Since the measure of an exterior angle is equal to the sum of its remote interior angles, we know that x = 65 + 56 = 121°.

One root of the quadratic equation x^2 − 2x + m = 0 is 9. If the other root is n, what is n−m?
mote1985 [20]
9^2-2*9+m=0\\
\\
81-18+m=0\\
\\
m=-63

x^{2} -2x-63=0\\
\\
\Delta=(-2)^2-4.1.(-63)=4+252=256\\
\\
x=\frac{2 \pm 16}{2}\\
\\
x_1=\frac{18}{2}=9\\
\\
n=x_2=\frac{-14}{2}=-7\\
\\
n-n=-7-(-63)=-7+63=56

NARA [144]

9514 1404 393

Answer:

  cot(θ) = 4/5

Step-by-step explanation:

In the polar/rectangular coordinate representation (x, y) ⇔ (r; θ), we know that ...

  (x, y) = (r·cos(θ), r·sin(θ))

From the various trig definitions and identities, we also know that ...

  cot(θ) = cos(θ)/sin(θ) = (x/r)/(y/r) = x/y

For the given (x, y) = (-4, -5), the cotangent is ...

  cot(θ) = -4/-5 = 4/5
