$~~~~\dfrac{d}{dx} \left(\dfrac{3}{1 + \sec x} \right)\\\\\\=3 \dfrac{d}{dx} \left( \dfrac 1{ 1+ \sec x} \right)\\\\\\=3 \dfrac{d}{dx} (1+ \sec x)^{-1}\\\\\\=3 (-1) (1 + \sec x )^{-1 -1} \dfrac{d}{dx}( 1 + \sec x)\\\\\\=-3(1 + \sec x)^{-2} ( 0 + \sec x \tan x)\\\\\\=-\dfrac{3\sec x \tan x}{(1 + \sec x)^2}$

I need help on the following questions.

Zigmanuir [339]

For the first one, you just need to divide the amount of feet by 3 to get the amount of yards (there are three feet in a yard).

1431 / 3 = 476 2/3

The 102nd floor of the Sears Tower is 476 2/3 yards from the ground.

Second, you just need to multiply the amount of centimeters by 10 (there are 10 millimeters in a centimeter).

16 * 10 = 160

The butterfly has a wingspan of 160mm.

Third, the measurements are indeed
7. =
8. =
9. <
10. >
11. >
12. =

Fourth, you just need to know your conversion factors.
1. There are 3 feet in a yard. 42 / 3 = 14 yards
2. There are 1000 meters in a kilometer. 2350 / 1000 = 2.35 km
3. 12 inches in a foot. 18 * 12 = 216 inches
4. 10 decimeters in a meter. 289 * 10 = 2890 dm
5. 1760 yards in a mile. 1760 * 5 = 8800 yds
6. 10 millimeters in a centimeter. 35 * 10 = 350 mm

Hope that was helpful =)
