During these years of experience i have learned and worked on various skills that help in making me well versed in any kind of technical work or roles. I am looking forward to keep improving myself for my future and prove myself. I want to be an asset to my future employer through hard work, commitment and knowledge sharing where I can use my experience and skill sets efficiently
Consider the equation $5 x-17=10 x-27 .$ Solve for $x$.
The speed $v$ of a bullet satisfies the relation $v t=95 \mathrm{m},$ where $t=0.25 \mathrm{s}$. Find $v$.
Consider the equations$$5 x+2 y=13 \quad-3 x+7 y=25$$a. Put each equation into the standard format for a straight line $(y=m x+b)$ and plot both lines. Use your graph to find the point $(x, y)$ where these lines intersect.b. Use algebra to find the values of $x$ and $y$ that simultaneously satisfy these two equations.c. How do your answers to parts (a) and (b) compare?
Two well-known organic chemicals are benzene, $\mathrm{C}_{6} \mathrm{H}_{6}$ and propane, $\mathrm{C}_{3} \mathrm{H}_{8}$. Benzene has molecular weight of $78.11 \mathrm{g} / \mathrm{mol}$ and propane $44.096 \mathrm{g} / \mathrm{mol}$, where the molecular weight is a usefulmeasure in chemistry and is defined as the mass of 1 mole (Avogadro's number) of molecules oratoms. Determine the molecular weight (in g/mol) of pure hydrogen and pure carbon. Hint: The subscripts in the molecular formula are the number of atoms of that type per molecule. Set up two simultaneous equations to solve for the molecular weights.
Two ropes are attached to a skater as sketched in Figure $\mathrm{P} 4.1$ and exert forces on her as shown. Find the magnitude and direction of the total force exerted by the ropes on the skater.
A major oil company has developed a new gasoline additive thatis supposed to increase mileage. To test this hypothesis, ten carsare randomly selected. The cars are driven both with and withoutthe additive. The results are displayed in the following table. Canit be concluded, from the data, that the gasoline additive doessignificantly increase mileage?Letd=(gas mileage with additive)−(gas mileage without additive).Use a significance level of α=0.05 for the test. Assume that thegas mileages are normally distributed for the population of allcars both with and without the additive.
