Given that the value of an investment in x years is given by S = 1900(1.02) 4×, we want to find the amount that will result in 9 years. To do this, we let x = the proper order of operations. In the last step, round your answer to the nearest cent. 4 S=1900(1.02) = 1900(1.02) = $ in the formula and compute the result using a calculator. Remember to use

Carry out the following operations as if they were calculations of experimental results with the correct number of significant figures. а. 3.215 x 13.2 ÷ 0.218 = | b. (4.123 x 0.12) + 24.2 = с. (17.103 + 2.03) x 1.02521 = d. 2.02m + 8.102m - 0.0297m = е. 1.2 cm x 1.79 cm

The number of Rednwood pine trees per acre N(d) in a test plot can be approximated by the following model N(d)=68(-0.04d); 5 less than or equal to d less than or equal to 40 where d is the average diameter (in feet) of the trees when they are measured 3 feet off the ground. To the nearest hundredth of a foot, find the average diameter of the trees in a 1-acre test plot containing 21 trees. Explain how you got your answer.
