please show and explain all work. i am not understanding how to do this. Find the equation of the tangent line to the graph of f(x) at the given point. f(x) = V12x + 24 at (1,6) Show all your work on the paper and submit it on Canvas. The equation of the tangent'line to the graph of f(x) at the given point is
How many total atoms are in 0.810 g of P,0,? total atoms:
How would I find the percent of P2O5 present in a sample of KH2PO4? I know that phosphorus is 22.761% by mass of KH2PO4. I weighed out 0.422g of KH2PO4, then filtered it with water. Then I added 10 mL of 0.4 M MgSO4 to the filtrate. Then I added 1 mL of 6 M NH3 slowly with a disposable pipet while stirring. Then I touched the stirring rod to red litmus paper. Then I continued adding 1 mL NH3...
I need help understanding how to complete this question. I am not sure if the items in the table are correct, except I do know that the weight of the paper is correct. calculate how many moles of CaCl2•2H2O are present in 1.50 g of CaCl2•2H2O and then calculate how many moles of pure CaCl2 are present in the 1.50 g of CaCl2•2H2O. Record the answers in Data Table 1. Use the information and examples provided in the Exploration and...
I am having trouble understanding and interpreting relative risk in a cohort study. From my understanding, it is the ratio of the risk of an exposed group to a risk of a nonexposed group. I do not understand how to interpret the ratio if it's more than 1, less than 1, or equals 1. I do not understand what it means when something has a positive association or negative association.
I am having trouble understanding how the value for k3 is found in this problem. I understand the rest of the problem. If someone could explain the part to me instead of just copying and pasting the solution that would be great. Three springs and a mass are attached to a rigid, weightless bar PQ as shown in Fig. Find the natural frequency of vibration of the system. k2 ki
