[Jawaban] If an individual falls and is unconscious, what type of reporting is required? A. Emergency B. Urgent C. Certain time D. Routine

[Jawaban] The height, [tex]$h$[/tex], of a falling object [tex]$t$[/tex] seconds after it is dropped from a platform 300 feet above the ground is modeled by the function [tex]$h(f)-300-16 t^2$[/tex]. Which expression could be used to determine the average rate at which the object falls during the first 3 seconds of its fall? A. [tex]$h(3)-h(0)$[/tex] B. [tex]$h(\frac{3}{3})-h(\frac{0}{3})$[/tex] C. [tex]$\frac{h(3)}{3}$[/tex] D. [tex]$\frac{h(3)-h(0)}{3}$[/tex]

[Jawaban] Creating an Exponential Model In this activity, you will formulate and solve an exponential equation that models a real-world situation. Emma doesn't have experience using credit cards. In fact, she just got her first one. She is also about to start her first year of college. She uses her new credit card to purchase textbooks for her classes. The total comes to $300. These are the terms of her credit card: - It has a $15 \% annual interest rate. - The interest is compounded monthly. - The card has $0 minimum payments for the first four years it is active. The expression that models this situation is [tex]P\left(1+\frac{r}{n}\right)^{n t}[/tex], where [tex]P[/tex] represents the initial, or principal, balance; [tex]r[/tex] represents the interest rate; [tex]t[/tex] represents the time in years; and [tex]n[/tex] represents the number of times the interest is compounded per year. Part A Question Identify the values of [tex]P, r[/tex] and [tex]n[/tex] in the expression [tex]P\left(1+\frac{r}{n}\right)^{n t}[/tex] based on Emma's situation. Then substitute those values into the formula to write a simplified exponential expression in terms of time. Replace the variables [tex]a, b[/tex], and [tex]c[/tex] to write the expression.

[Jawaban] Why is providing foresight considered an advantage of planning? A. It allows you to better predict any problems that might occur. B. It gives you a holistic view of the task. C. It clearly states why individuals who plan have a competitive edge over those who do not. D. It allows everyone to know where they must be, what they must do, and when it should be done.
