Simplify cos^2 A/1+sin A
Stels [109]

Answer:

\displaystyle \frac{\cos^2(A)}{1+\sin(A)}=1-\sin(A)

Step-by-step explanation:

We want to simplify:

\displaystyle \frac{\cos^2(A)}{1+\sin(A)}

Recall the Pythagorean Identity:

\sin^2(A)+\cos^2(A)=1

So:

\cos^2(A)=1-\sin^2(A)

Substitute:

\displaystyle =\frac{1-\sin^2(A)}{1+\sin(A)}

Factor. We can use the difference of two squares pattern:

\displaystyle =\frac{\left(1-\sin(A))(1+\sin(A))}{1+\sin(A)}

Cancel. Hence:

\displaystyle \frac{\cos^2(A)}{1+\sin(A)}=1-\sin(A)

What is the relationship between 9.125×10−3 and 9.125×102 ? Select from the drop-down menus to correctly complete the statement.
JulsSmile [24]
Given 9.125\times10^{-3} and 9.125\times10^{2}

9.125\times10^{2}=9.125\times10^{-3+5} \\  \\ =9.125\times10^{-3}\times10^5=9.125\times10^{-3}\times100000

Therefore, 9.125\times10^{-3} is 100,000 times less than 9.125\times10^{2}.

Vsevolod [243]

Answer:

Cost of selling price = $5.33 (Approx)

Step-by-step explanation:

Given:

Cost of price of cookie = $3 each

Number of cookies = 80

Damaged = 10%

Markup on cost = 60%

Find:

Cost of selling price

Computation:

Total cost of cookie = 80 × 3 = 240

Markup price = 240 + 240(60%)

Markup price = 384

Number of damage cookies = 80(10%) = 8

Remain cookies = 80 - 8 = 72

Cost of selling price = Markup price / Remain cookies

Cost of selling price = 384 / 72

Cost of selling price = $5.33 (Approx)
