Simplify the expression<br><br>cot^2x - cot^2x cos^2x
andrew-mc [135]
Cot^2x - cot^2x cos^2x
= cot^2x - {(cot^2x)(cos^2x)}
= cot^2x { 1 - cos^2x }
= cot^2x { sin^2x }
= (cos^2x/sin^2x) { sin^2x }
= cos^2x

A. k/5 = 3; k=<br> B. 3.5d = 70; d=<br> C. 4 1/2 = 1 1/2n; n=<br><br> Solve each equation.
Kryger [21]

Answer:

Step-by-step explanation:

A. k/5 = 3:  Isolate k by multiplying both sides of this equation by 5:

k = 15

       

B. 3.5d = 70;  Divide both sides by 3.5, obtaining d = 20

C. 4 1/2 = 1 1/2n;   Rewrite 4 1/2 and 1 1/2 as improper fractions:

  9/2 = (3/2)n.  Now multiply both sides by (2/3):  3 = n
