Quadratic Equations in Vertex Form have a general form: #color(red)(y=f(x)=a(x-h)^2+k#, where #color(red)((h,k)# is the #color(blue)("Vertex"#

2016年11月23日 · 2/5 is already a fraction. It represents having 2 pieces out of a possible 5. If, by chance, you are seeking the decimal representation of this fraction, you can convert easily by simply dividing 5 into 2: 2-:5<=>5)bar2.00 " "0.4 5)bar2.00 " "20 " "bar" " " "0 2/5 in decimal form is 0.4, or 40%. (Example: scoring 2 out of 5 on a quiz is a score of 40%.)

How do you find the first 4 positive values and first two negative values for x such that cos x = -0.67? Why is cos -pi/6 the same as cos pi/6? How do you find the cot of a 50 degree angle?

To convert ppm you x by #10^4# to give 300ppm. Michael · 2 · Dec 9 2014 Questions

2017年10月18日 · From the diagram we see the object point #(-2,-5)# is mapped to #(x',y')# by a reflection in the line #X=2# we note (1) the y-coordinate is unaffected. (2) for reflections the distance from the line of reflection to the object is equal to the distance to the image point. #:. a=2+2=4units# so the image point is 4 units from the line of reflection

2016年6月5日 · Thus, the pOH = 9.30. The second method is much easier. Just take the -log of the concentration of hydrogen ions: -log(2.0xx10^(-5 M) = 4.70 That value represents the pH of the solution. To obtain the pOH from the pH just do 14 - pH = pOH Then you should arrive at the same answer: 14 - 4.70 = 9.30

Frequency and period are related inversely. A period #P# is related to the frequency #f# # P = 1/f#. Something that repeats once per second has a period of 1 s.

2015年5月10日 · x^4 + x^2 + 1 = (x^2 + x + 1)(x^2 - x + 1) To find this, first notice that x^4 + x^2 + 1 > 0 for all (real) values of x. So there are no linear factors, only quadratic ones. x^4 + x^2 + 1 = (ax^2 + bx + c)(dx^2 + ex + f) Without bothering to multiply this out fully just yet, notice that the coefficient of x^4 gives us ad = 1. We might as well let a = 1 and d = 1. ... = (x^2 + bx + c)(x^2 …

Evaluate the expression #3x-2y# when #x=4# and #y=5# #3(4)-2(5) = 12 - 10 = 2# If we change the values to #x=5# and #y=4#, we get #3(5)-2(4) = 15 - 8 =7#. Note: To avoid saying exactly the same thing over and over, we use the following to mean the same thing: evaluate the expression when #x = 2# evaluate the expression for #x = 2#

2018年7月21日 · The most common way to solve a quadratic equation to the fourth power would be using x^2 instead of x when factoring, an example is shown below. Depending on the specific problem, there are different ways that you may be able to solve the quadratic equation. Sometimes, you are able to factor each term by a numerical value, an example where this can …
