Answer: OPTION B.

Step-by-step explanation:

By definition, reflection is a kind of transformation in which the lengths do not change.

As you can see in the figure, the length of PR is 8 units. Then, keeping on mind the definition, when the triangle PQR was reflected across the y-axis, the triangle P'Q'R' obtained has the same lenghts as the triangle PQR.

Therefore, you can conclude that the lenght P'R' would be: 8 units.

DT/dt=k(T-38)
ln(T-38) = kt+C
T=38 + Ce^(-kt)
Since T(0)=75, 75 = 38+C, so C=37
Since T(30)=60, 60 = 38+37e^(-30k), so k = -ln(22/37)/30 ~= -0.017329
T(60) = 38+37e^(-0.017329*60) = 51.1°F

Verify the identity <br> Cos^2x-Sin^2x=1-2sin^2x

jek_recluse [69]

$Cos^2x-Sin^2x=1-2sin^2x \\ Cos^2x-Sin^2=cos(2x) \\ 1-2sin^2=cos2x \\ cos(2x) =cos2x \\ \\ \\ Cos^2x-Sin^2x=1-2sin^2x \\ \mathrm{cos^2x+sin^2x=1 ~~~\Rightarrow ~~cos^2x=1-sin^2x} } \\ 1-sin^2x-sin^2x=1-2sin^2x \\ 1-2sin^2x=1-2sin^2x$
