Answer:

Step-by-step explanation:

$\frac{sinxcos^3x-cos xsin^3x}{cos^42x-sin^42x} \\=\frac{sin x cos x(cos^2x-sin ^2 x)}{(cis^2 2x+sin^2 2x)(cos^2 2x-sin ^22x)} \\=\frac{2sin x cos x cos 2x}{2(1)(cos 4x)} \\=\frac{sin 2x cos 2x}{2 cos 4x} \\=\frac{2 sin 2x cos 2x}{4 cos 4x} \\=\frac{sin 4x}{4 cos 4x} \\=\frac{1}{4} tan 4x$

Hello from MrBillDoesMath!

Answer:

9/2 > 3/2 (slope of <u>greater than.</u>..)

Discussion:

This seems like an odd question. We can say that

9/2 > 3/2

so the slope of the line with m = 9/2 is greater than (in fact, 3 times greater than) the slope of the line with slope m = 3/2

Thank you,

Schach [20]

Answer:

$22,832.47

Step-by-step explanation:

$32,600.00 × 21% = $6,846.00

$32,600.00 - $6,846.00 = $25,754.00

$25,754.00 × 7.65% = $1,917.18

$25,754.00 - $1,917.18 = $23,783.82

$23,783.82 × 4% = $951.35

$23,783.82 - $951.35 = $22,832.47
