Find the equations of the tangent lines to x2+y2=1 at x=0, x=1 and x=35.

Assuming the equation is x^2 + y^2 = 1, then that's a circle, with radius 1, centered on the origin [0,0].

So there are two tangents at x = 0. They are y = 1, and y = -1 (horizontal lines).

There is one tangent at x = 1. It is x = 1 (a vertical line).

There is no tangent at x = 35, because the original equation has no solution at x = 35.

Find x, and then any unknown angles in the quadrilateral.<br> x= ?
sertanlavr [38]

Answer:

x=65

other angle= 165

Step-by-step explanation:

quadrilaterals always have a total of 360 degrees

because of this you can set up an equation and solve

360=90+40+x+(4x-95)

360=130+5x-95

360=35+5x

325=5x

65=x

plug this in to find missing angle

4(65)-95=165

A boat takes 4 hours to go 12 miles upstream. It can go 32 miles downstream in the same time. Find the rate of the current and t
galina1969 [7]

The speed upstream is the difference between the boat speed and the current speed. It is (12 mi)/(4 h) = 3 mph.

The speed downstream is the sum of the boat speed and the current speed. It is (32 mph)/(4 h) = 8 mph.

The speed of the boat is the average of these: (3 + 8)/2 = 5.5 mph.

The speed of the current is that less the difference: 5.5 - 3 = 2.5 mph.

_____

<u>Check</u>

Boat + Current = 5.5 + 2.5 = 8 mph

Boat - Current = 5.5 - 2.5 = 3 mph
