Question 1 Determine the slope for line 2x+12y-6=0 2x+12y=6 12y=-2x+6 y=-2x/12+6/12 y=-x/6+1/2 ∴m=-1/6 Find the slope of the required line‚ which is "m" (-1/6)("m" )=-1 (m)=6 Now‚ substitute m=6 into equation y=mx+c ‚i.e. y=6x+c. This line passed through point (2‚4). So‚ we substitute x=2‚y=4 into y=6x+c. 4=6(2)+c 4-12=c c=-8 ∴ The equation of the straight line that we are looking for is y=6x-8

1. I learned a couple of key things about lab safety and procedure during this experiment. While working with the hot plates‚ I learned to pay a lot of attention to whether or not the hot plate was plugged in or turned on‚ as well as whether or not the wax was getting too hot. Measuring each substance into the cup was an important experience because it taught me to be deliberate and careful when measuring so as to not waste materials‚ making sure we did not have to start over. While this lab is a

logarithm in the real world or have ever needed to use one‚ there are still many uses for logs that are actually quite common. Three common uses for logs in the real world are calculating compound interest‚ calculating population growth or decay‚ and carbon dating. Using logs is a key component when solving for compound interest. Whenever you are calculating the interest on an investment that is compounded continuously‚ a natural exponential function is used. To solve for continuously compounded interest

The purpose of the lab was to find out the chemical elements based on the color of the flame that elements make by their reaction. The work we completed in the lab was testing the chemical effects of the flame from the chemicals. We tested different elements and wrote down our observations. I accomplished the knowledge of testing chemicals and making responses based on our observations.Electrons are the particles found in the chemicals that may be responsible for the production of colored light.
