Answer:

The cost of each CD without tax us $16.20

Step-by-step explanation:

Given that:

Price to two CDs with tax = $34.20

Tax = $1.80

Cost of CDs without tax = Total cost - Amount of tax

Cost of CDs without tax = 34.20 - 1.80 = $32.40

Price of each CD  = \frac{32.40}{2}

Price of each CD = $16.20

Hence,

The cost of each CD without tax us $16.20

VladimirAG [237]
1)

LHS = cot(a/2) - tan(a/2)

= (1 - tan^2(a/2))/tan(a/2)

= (2-sec^2(a/2))/tan(a/2)

= 2cot(a/2) - cosec(a/2)sec(a/2)

= 2(1+cos(a))/sin(a) - 1/(cos(a/2)sin(a/2))

= 2 (1+cos(a))/sin(a) - 2/sin(a)) (product to sums)

= 2[(1+cos(a) -1)/sin(a)]

=2cot a

= RHS

2.

LHS = cot(b/2) + tan(b/2)

= [1 + tan^2(b/2)]/tan(b/2)

= sec^2(b/2)/tan(b/2)

= 1/sin(b/2)cos(b/2)

using product to sums

= 2/sin(b)

= 2cosec(b)

= RHS

eff can paint 28 square feet every 30 minutes. Angela can paint 50 square feet every hour. Who can paint faster, and by how many
lisabon 2012 [21]
Guessing “eff” is Jeff ;)
28 sq feet/30 min = 56 sq feet/60 minutes

Angela
50 sq feet/60 min

So Jeff paints 6 square feet more per hour.
