Cos9x - cos5x = -2sin2x.sin7x
sin17x - sin3x = 2sin7x.cos10x
so f(x) = $\frac{-2sin2x.sin7x}{2sin7x.cos10x}$ = $\frac{-sin2x}{cos10x}$

4. Jonathan takes his dog to be groomed. The fee to groom the dog is $80 plus 6.75% tax.

frutty [35]

Step-by-step explanation:

Tax charge

80 × 6.75/100 = 5.4

Cost + tax charge

80 + 5.4 = 85.4

Tip (15% of cost and tax)

85.4 × 15/100 = 12.81

(Cost + tax charge + tip)

85.40 + 12.81 = 98.21

therefore, $95 is not enough.

At a football game Jasmine bought a soft pretzel for $2.25 in a bottle of water for $1.50 she paid with a $5 bill how much thing

andrew11 [14]

Answer:

$1.25.

Step-by-step explanation:

We have been given that at a football game Jasmine bought a soft pretzel for $2.25 in a bottle of water for $1.50 she paid with a $5 bill.

First of all let us find how much Jasmine spent on soft pretzel and water bottle by adding the cost of both items.

$\text{Total amount spent on both items}=2.25+1.50$

$\text{Total amount spent on both items}=3.75$

To find the amount that Jasmine will get as a change we will subtract the amount spent on both items from 5.

$\text{Amount of change that Jasmine will get}=5-3.75$

$\text{Amount of change that Jasmine will get}=1.25$

Therefore, Jasmine will get $1.25 back as change.
