PLEASE HELP WORTH 50 POINTS
VashaNatasha [74]

Answer:cos( A + B ) = cosAcosB - sinAsinB ;

cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;

                     

tan²(x) - sin²(x) = sin²(x)/cos²(x) - sin²(x)

… = sin²(x) (1/cos²(x) - 1)

… = sin²(x) (sec²(x) - 1)

… = sin²(x) tan²(x)

Answer:

900 m

Step-by-step explanation:

since it is an irregular figure, you would have to find the area of the rectangles making it up separately.

18 x 30 = 540

6 x 60 = 360

540 + 360 = 900

Refering to the equation, tell how
Ugo [173]

Answer:

  the scale factor is the vertical expansion factor.

Step-by-step explanation:

The scale factor of 2 in

  g(x) = 2·F(x)

means g(x) is a <em>vertical expansion</em> (not shrink) of F(x) — by a factor of 2.

_____

<em>Additional comment</em>

The equation g(x) could be considered to be ...

  g(x) = F(x·√2)

in which case g(x) could be interpreted as a <em>horizontal shrink</em> by a factor of (√2)/2. Squeezing a parabola horizontally has the same effect on its appearance as stretching it vertically.
