Problem 2 An interior column for a tall concrete structure carries total service loads D=2200kN and L=2300KN. The column is 550mm x 550mm in cross section and is reinforced with 12 o 36 bars centered 75 mm from the column faces (equal number of bars each face). Material strengths for the column, f = 28MPa psi and fy = 420 MPa. The column will be supported on a square footing, with the bottom of the footing 1.8m below grade. Design the footing, determining all concrete dimensions and amount and placement of all reinforcement, including length and placement of dowelsteel. No shear reinforcement is permitted. The allowable soil bearing pressure is 380 kN/m2. Material strengths for the footing are fo = 21MPa psi and fy = 420 MPa.

please do both please 3. When they work together, Jerry and Leo can do their weekly house chores in 58 minutes. When Leo works alone he can finish the chores in 12 minutes less time than Jerry. When Jerry works alone, how long will it take him to do the weekly chores in the house? 4. For each pair of functions determine where the zeros of the original function occur and state the equations of the vertical asymptotes of the reciprocal function. If no zeros exist, state so. a) 9(t)= 7 - 131+30 b) j(w) x2 + 1

4) The population of a town is modelled by P(t) = 25t2 + 150t + 25 000, where P(t) is the size of the population and t is the number of years since 1990. (a) Calculate the average rate of change of population with respect to time from 1990 to 1993. Include units. [3] [ (b) Estimate the instantaneous rate of change of population with respect to time in the year 1995. Include units. [3]

On July 1, 20Y1, Danzer Industries Inc. issued $60,000,000 of 10-year, 8% bonds at a market (effective) interest rate of 10%, receiving cash of $52,522,704. Interest on the bonds is payable semiannually on December 31 and June 30. The fiscal year of the company is the calendar year. Required: 1. Journalize the entry to record the amount of cash proceeds from the issuance of the bonds on July 1, 20Y1. 2. Journalize the entries to record the following: a. The first semiannual interest payment on December 31, 20Y1, and the amortization of the bond discount, using the straight-line method. b. The interest payment on June 30, 20Y2, and the amortization of the bond discount, using the straight-line method. 3. Determine the total interest expense for 20Y1. 4. Will the bond proceeds always be less than the face amount of the bonds when the contract rate is less than the market rate of interest? 5. Compute the price of $52,522,704 received for the bonds by using the present value tables.

An experiment consists of tossing a single die and observing the number of dots that show on the upper face. Events A, B, and C are defined as follows. A: Observe a number less than 4. B: Observe a number less than or equal to 2. C: Observe a number greater than 3. Find the probabilities associated with the following events using either the simple event approach or the rules and definitions from this section. (Enter your probabilities as fractions.) (a) S (b) AB (c) B (d) ABC (e) ANB (f) Anc (9) BNC (h) AUC (0) BUC
