The answer is = 1 + sin x
Explanation
we need
a^2 - b^2 = (a+b) (a-b)
we use
cos^2 x + sin^2 x = 1
cos^2 x = 1 - sin^2 x = ( 1 + sin x) ( 1 - sin x )
therefore
cos ^2 x over 1 - sin x = 1+ sin x
104 square yards
The formula for area of a rectangle is length times width.
A = length x width
A = 13 x 8
A = 104
Since the units on each side are yards, the area is in square yards.
Answer:
<em>Answer: A'Reana's weekly allowance is $100</em>
Step-by-step explanation:
<u>Backward Solution</u>
To solve some problems, we can work backward, using the inverse operations, to arrive at the solution.
The problem explains a sequence of expenses A'Reana does with her weekly allowance. In the end, she had $37.50.
That final balance came when she last spent $7.50 on a pizza. Thus, before that, she had $37.50+$7.50=$45
This balance is half of her previously remaining money. The other half was spent on a new shirt. Thus she had 2*$45=$90.
Those $90 were left after she gave $10 to her friend Taylor, thus, the initial money was $90+$10 = $100
Answer: A'Reana's weekly allowance is $100
Actually, there is no such thing. You may be thinking of PEMDAS, which is the abbreviation for the order of operations in math.
P stands for Parentheses
E stands for Exponents
M stands for multiplication and D stands for dividing. If there are both of these operations in the problem, do them from left to right.
A stands for Addition, and S stands for Subtraction. Same rules for multiplying and dividing.
Starting with P, you would go down the list of letters when solving a multi operation problem. <3 I hope I helped!!
