Verify the identity. Show your work. cos(α - β) - cos(α + β) = 2 sin α sin β

Please help me with this ratio.

Charra [1.4K]

Answer:

$\frac{inches}{minute}$

Change the feet to minutes by multiplying by 12, and change the hour to minutes.

Speedy: $\frac{240}{60}$

Slowpoke: $\frac{80}{30}$

Cleo: $\frac{96}{10}$

Speedy is the fastest.

$\frac{feet}{hour}$

Speedy: $\frac{20}{1}$
Slowpoke: $\frac{\frac{6.666666667}{.5}}{30}$
Cleo: $\frac{8}{\frac{1}{6}}$

Change minutes to feet by dividing and change the minutes to hours by multiplying.

Line l in the xy-plane is perpendicular to the line

jeka57 [31]

The line x = 2 is perpendicular to the x-axis.
That is to say it is vertical and it’s slope is undefined.

Line l must be horizontal so it has a slope of 0
