Passes through (2,2), slope = 3
nikdorinn [45]

Answer:

y - 2 = 3(x - 2)

Step-by-step explanation:

Hello!

Please consider using the point-slope formula for the equation of a straight line, because in this case it's the easiest way to go.

(2,2) is one point on the line, and the slope is m = -3.

Thus, y - k = m(x - h) becomes y - 2 = 3(x - 2).

A line passes through the two points: (1, 10) and (6,5).
Snowcat [4.5K]

Answer:

<em>(a). - 1 ; (b). y = - x + 11</em>

Step-by-step explanation:

(1, 10)

(6, 5)

<em>(a).</em> <em>m</em> = \frac{y_{2} -y_{1} }{x_{2} -x_{1} } = \frac{5-10}{6-1} = <em>- 1</em>

<em>(b).</em> y - 5 = - 1(x - 6)

<em>y = - x + 11</em>

A triangle has two constant sides of length 5 feet and 7 feet. The angle between these two sides is increasing at a rate of 0.9
o-na [289]

Answer:12.74 ft^2/s

Step-by-step explanation:

Given

Two sides of triangle of sides 5 ft and 7 ft

and angle between them is increasing at a rate of 0.9 radians per second

let \thetais the angle between them thus

Area of triangle when two sides and angle between them is given

A=\frac{ab\sin C}{2}

A=\frac{5\times 7\times \sin \theta }{2}

Differentiate w.r.t time

\frac{\mathrm{d} A}{\mathrm{d} t}=\frac{35\cos theta }{2}\times \frac{\mathrm{d} \theta }{\mathrm{d} t}

at \theta =\frac{\pi }{5}

\frac{\mathrm{d} A}{\mathrm{d} t}=\frac{35\times cos(\frac{\pi }{5})}{2}\times 0.9

\frac{\mathrm{d} A}{\mathrm{d} t}=12.74 ft^2/s
