If sin(θ -π/2) = 0.73.. find cos (-θ) plz explain how to solve

Step-by-step explanation:

It is given that:

Formula to be used:

Using Formula (1) written above:

Now, using Formula (2) written above:

So, we can say that:

We have to find the value of .

Using Formula (3) written above:

So, ultimately we need to find the value of

Using equation (1):

So, the answer is .

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
