The slope of a line is 0 and it contains the point (3,1)

Sedaia [141]

Answer:

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point on a line

We have m = 0, (3, 1) → x₁ = 3, y₁ = 1.

Substitute:

$y-1=0(x-3)$

$y-1=0$ add 1 to both sides

$y=1$

Other method.

If the slope is equal 0, then it's a horizontal line.

The equation of a horizontal line: y = a.

We have the point on a line (3, 1) → x = 3, y = 1.

Therefore the equation is y = 1.

Two boats sail away from a buoy making a 90 degree angle. The first boat is 165 meters away and is traveling at 25 m/s. The seco

NikAS [45]

Answer:

Step-by-step explanation:

lets say in the shown triangle x=165

so speed $\frac{dx}{dt} =25$

and $\frac{dy}{dt} =35$

Also since distance = speed* time

time = pi minutes = pi/60 seconds

y = $\frac{35\pi \pi }{60}$

y = $\frac{7\pi }{12}$

Now using the pythagorean :

$x^2+y^2=z^2\\so \\165^2+(\frac{7\pi }{12} )^2 =z^2$

derivate the equation so we get :

$x\frac{dx}{dt} +y\frac{dy}{dt} =z\frac{dz}{dt} \\$ $165*25+35*\frac{7\pi }{12}=\sqrt{165^2+(\frac{7\pi }{12})^2} *\frac{dz}{dt}$

$\frac{dz}{dt} =25.387$ m/s

So Rate of change = 25.387 m/s

Answer:

Yes

Step-by-step explanation:

Each input must only have one output. In other words, an x-value goes with one y-value. in this model, each input has an output.
