What is the Co ordinates to fill in the grid in the top left?
wolverine [178]

Answer:

a ) x = - 3, y = 5

x = 0, y = 2

x = 5, y = - 3

b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.

Step-by-step explanation:

y = 2 - x

When x = - 3,

y = 2 - x

= 2 - ( - 3 )

= 2 + 5

y = 7

When x = 0,

y = 2 - x

= 2 - 0

y = 2

When x = 5,

y = 2 - x

= 2 - 5

y = - 3

b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.

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
