Nov 2, 2016 · x= 0, -4 x(x+4) = 0 x/x(x+4) = 0/x x+4 = 0 x+4-4 = 0-4 **x = -4** x(x+4) = 0 x((x+4)/(x+4)) = (0/(x+4 )) **x = 0**

symbol. A * symbol is not necessary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x – 1). Order of Operations

Jul 31, 2016 · One of the properties of zero is that "Anything times 0 is equal to 0" So, # a = 0, or b=0, or c=0, or d=0.# To have a 0 from multiplying means we must start with a 0. In #(x-4)(x-3)=0" "# we have the product of two factors equal to 0, ONE of them MUST be 0. If #x-4 = 0" "rArr x = 4# If #x-3 = 0" "rArr x = 3# These are the two solutions.

Aug 24, 2015 · d/dx(4^x) = 4^x ln4 In general for b>0, we have d/dx(b^x) = b^x lnb And when we need the chain rule, we have d/dx(b^u) = b^u (lnb) d/dx(u) Proof of General rule b^x = (e^lnb)^x " " (remember that e^lnu = u) So b^x = e^(xlnb) " " (because (a^r)^s = a^(rs) = a^(sr)) d/dx(e^(xlnb)) can be found by the chain rule: d/dx(e^(xlnb)) = e^(xlnb) d/dx(xlnb) = e^(xlnb) lnb " " (lnb is a …

May 3, 2019 · Find the mean and standard deviation for the random variable x given the following distribution Answers · 3 using interval notation to show intervals of increasing and decreasing and postive and negative

Nov 15, 2016 · How do you find the area between #g(x)=4/(2-x), y=4, x=0#? Calculus Using Integrals to Find Areas and Volumes Calculating Areas using Integrals 1 Answer

Sep 12, 2012 · so (4+4+4+4)+(4+4+4+4)+4-(4+4+4+4) this is really 4*9-16=36-16=20. Math is how you look at it. There are so many ways to solve one problem. as long as you play by the rules and you don't "cheat" :D it is a great way to get students to think outside the box, problem solve and critically think. these are all vitally important skills in life.

Feb 11, 2018 · make x the subject of the formula. x - 4 = 0 add 4: x = 0 + 4 x = 4 graph as a vertical line, where x is the constant 4.

Apr 29, 2023 · = π ∫[0, 2] (x^2 + 2x + 1) dx = π [x^3/3 + x^2 + x] [0, 2] = π (8/3 + 4 + 2) = 14π/3. Therefore, the volume of the solid is 14π/3. 2. For the second problem, we need to find the volume of the solid obtained by rotating the region bounded by the curves y = √x - 1, y = 0, and x = 5 about the x-axis. Let's first sketch the region and the ...

Apr 2, 2016 · If you need to find all values of x between 0 and 360 (or 0 to 2pi), there would be 8 answers. If x goes from 0 to 360, then 4x goes from 0 to 1440. For example, 90, 450, 810, and 1170 are all coterminal (just adding 360 each time), but if we set them equal to 4x, then you get 4 angles that make your equation work.
