Answer:

y = 5 is the equation of the line which passes through these 2 points.

Step-by-step explanation:

The slope = (5 - 5) / (5 - (-5))

= 0

So the line is horizontal and passes through the y axis at y = 5.

Hailey earned $90 for working 12 hours. How much can she earn for working 29 hours
Afina-wow [57]

Answer:

She will make 217.50 for 29 hours

Step-by-step explanation:

We can find the rate per hour by dividing the money by the number of hours

90/12 =7.5 per hour

She makes 7.50 per hour

If she works 29 hours

Money = rate * hours

           = 7.5 * 29

           =217.50

She will make 217.50 for 29 hours

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

<u>derivate the equation so  we get :</u>

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 = <u><em>25.387 m/s</em></u>
