Hillary is using the figure shown below to prove Pythagorean Theorem using triangle similarity: In the given triangle ABC, angle A is 90° and segment AD is perpendicular to segment BC. The figure shows triangle ABC with right angle at A and segment AD. Point D is on side BC. Which of these could be a step to prove that BC2 = AB2 + AC2? (6 points) By the addition property of equality, AC2 plus AD2 = AB multiplied by DC plus AD2. By the addition property of equality, AC2 plus AD2 = BC multiplied by DC plus AD2. By the addition property of equality, AC2 plus AB2 = AB multiplied by DC plus AB2. By the addition property of equality, AC2 plus AB2 = BC multiplied by DC plus AB2.

Which statement is true? Point estimates are used to make inferences about population parameters. When we use the population mean and proportion to summarize information about the entire population, we call them point estimates. The population mean and proportion are always equal to their corresponding point estimates. The sample mean and sample proportion of a population are called population parameters. NextReset

The average annual salary of the employees of a company in the year 2005 was $70,000. It increased by the same factor each year and in 2006, the average annual salary was $82,000. Let f(x) represent the average annual salary, in thousand dollars, after x years since 2005. Which of the following best represents the relationship between x and f(x)?f(x) = 70(1.17)x f(x) = 82(1.17)x f(x) = 70(2.2)x f(x) = 82(2.2)x

Cliff Branch bought a home with a 10.5% adjustable rate mortgage for 30 years. He paid $9.99 monthly per thousand on his original loan. At the end of 3 years he owes the bank $65,000. Since interest rates have risen to 12.5%, the bank will renew the mortgage at this rate, or Cliff can pay the bank $65,000. He decides to renew and will now pay $10.68 monthly per thousand on his loan. (You can ignore the small amount of principal paid during the 3 years.)i cant figure this out
