If the hypotenuse of a right triangle has a value of 5in, and the shortest leg of the triangle has a value of 3in, what is the length of the other leg?
This can be solved by using the Pythagorean theorem c^2=a^2+b^2. Since we know c=5, and a=3, we can plug and chug to find the answer, by rearranging the equation to c^2-a^2=b^2. This means 5^2-3^2=b^2. So 25-9=16. Since b^2 is 16, take the square root to find b. This leaves the answer to be 4in.
Subject: Basic Math
Using the equation y=3x+14, find y if x=2.
Since the question gives you the value for x, all you have to do is plug it in! y=3(2)+14, which then is simplified to y=6+14, and with simple addition, y=20.
What is a bacteriophage?
A virus that infects bacteria. The virus does so by injecting its DNA into the bacteria. The DNA then replicates and matures into more viruses. These viruses then burst out, and essentially kill the bacteria.
