In WA, you can enter sec2(x) either by typing sec²(x), (sec(x))², or sec(x)2. Therefore, be aware of the difference between sec(x?) and sec(x)2. We must remember this syntax for this course. (a) Enter sec2(x). (b) Enter sec(x?). (c) sec2(x) Select your answer sec(x2). (d) sec2(x) Select your answer sec(x)².

A one of a kind necklace is worth $3200. The value of the necklace increases by 9% each year. Which explicit and recursive formulas can be used to model the situation. Please classify if each one is explicit or recursive

The average depreciation rate of a new boat is approximately 8% per year. If a new boat is purchased at a price of $75,000, which model is a recursive formula representing the value of the boat n years after it was purchased?->a 1) a = 75,000(0.08)” a = 75,000(1,08)" 11 n 2) a= 75,000 a = 75,000 a₁ = (0.92)" a₁ = 0.92(a,, -₁) 3) 4) 6 Savannah just got contact lenses. Her doctor said she can wear them 2 hours the first day, and can then increase the length of time by 30 minutes each day. If this pattern continues, which formula would not be appropriate to determine the length of time in

Expenses for a company for year 1 are $24,000. Every year thereafter, expenses increase by $1000 plus 3% of the cost of the prior year. Let a1 represent the original cost for year 1; that is, a1 = 24,000. Use a recursive formula to find the cost an in terms of an−1for each subsequent year, n≥ 2.

Consider a population that grows according to the recursive rule Pn = Pn-1 + 40, with initial population Po = 20. Then: P₁ = P₂= Find an explicit formula for the population. Your formula should involve n (use lowercase n) Pn = Use your explicit formula to find P100 P100 =
