Answer:
-1
Step-by-step explanation:
They already did the opposite reciprocal for you.
They have it in the form now.
To find b you just enter (x,y)=(8,1).
Let's do that.
Subtract 2 on both sides:
b=-1
You have the following expression:
To verify the identity, you have that the left side of the equation becomes:
(1 + cosx)(1 - cosx) = (1 - cos^2 x)
because of the product of an expression by its conjugate result in a difference of squares. Or simplfy by expanding the factors and simplying.
Next, you have:
1 - cos^2 x = sin^2 x
because the Pythagorean identity.
Then, the identity is verified.
Using proportions, it is found that:
- The fraction that shows the proportion of customers who voted for cheddar flavor is
- 56% of customers voted for cheddar flavor.
- A proportion is the <u>number of desired outcomes divided by the number of total outcomes</u>.
- A percentage is the <u>proportion multiplied by 100%</u>.
In this question, 42 out of 75 customers voted for the cheddar flavor, hence:
That is, the fraction that shows the proportion of customers who voted for cheddar flavor is
The percentage is:
56% of customers voted for cheddar flavor.

Answer:
Yes Sidharth is correct.
Step-by-step explanation:
The absolute value of a number is just the natural number of a number (the positive value of a number). So since Sidharth has a balance of -163 this means that he owes the bank $163, therefore you can find how much he ownes the bank just by determining the absoulte value of the number. Which would be $163, so yes Sidharth is correct.
