2. Find the instantaneous rate of change for each function f(x)=2x²-x+3 at x=0..

4x-3 2. Determine the interval over which the function is continuous. x+4

1. Find the average rate of change for the following functions over the given intervals. a) f(x)=4x-2x²+3x between x=-1 and x=4 b) y lnx between x=1 and x=4

1. Find all values x=a where the function is discontinuous, determine if the discontinuity is removable or non- removable. For each value of x, give the limit of the function as x approaches a. Be sure to note when the limit doesn't exist and explain how you know. a) f(x)= 2-x x²(x+5) b) f(x)= x²-9x x²+3x c) p(x)=-3x²+2x²+5x-8

Task Description: Read the following case study and answer the questions that follow. Ella is a 9-year-old third-grade student in an inclusive classroom. She has been diagnosed with Emotional and Behavioural Disorder (EBD). She has been struggling academically and socially due to challenges related to self-regulation, impulsivity, and emotional outbursts. Ella's behaviour includes frequent tantrums, defiance toward authority figures, and difficulty forming positive relationships with peers. Despite her challenges, Ella shows an interest in art and creative activities and demonstrates strong verbal skills when calm. Describe 2 strategies that could be implemented that could help Ella regulate her emotions in class (4 marks) Explain 2 strategies that could improve Ella’s social skills (4 marks) Identify 2 accommodations that could be implemented to support Ella academic progress and provide a rationale for your recommendation.(6 marks) Provide a detailed explanation of 2 ways…

1. Iodine-131 is tone of the most commonly used radioactive isotopes of iodine. It is used to treat hyper- thyroidism and some kinds of thyroid cancer. (a) Iodine-131 has a half-life of about 8 days. Find an expression for I(t), the mass of Iodine-131 remaining after t days, in terms of t and Io, the initial mass of Iodine-131 present at time t = 0. (b) If a dose of 0.9 mg of Iodine-131 is administered, how much is still present after 24 hours? (c) How much Iodine-131 is present after one week? Does your answer make sense?

Question 2: When John started his first job, his first end-of-year salary was $82,500. In the following years, he received salary raises as shown in the following table. Fill the Table: Fill the following table showing his end-of-year salary for each year. I have already provided the end-of-year salaries for the first three years. Calculate the end-of-year salaries for the remaining years using Excel. (If you Excel answer for the top 3 cells is not the same as the one in the following table, your formula / approach is incorrect) (2 points) Geometric Mean of Salary Raises: Calculate the geometric mean of the salary raises using the percentage figures provided in the second column named “% Raise”. (The geometric mean for this calculation should be nearly identical to the arithmetic mean. If your answer deviates significantly from the mean, it's likely incorrect. 2 points)   Starting salary % Raise Raise Salary after raise 75000 10% 7500 82500 82500 4% 3300…
