2016年12月20日 · Which is the solution to the equation #0.5x+4.2= 5.9#? Algebra Linear Equations Two-Step Equations and Properties of Equality. 1 Answer

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"#

2015年5月24日 · For a quadratic equation of the form y = and expression in x The x-intercepts occur at the points where y=0 Given (y=)((x+4.5)^2-6.25) We need to solve (x+4.5)^2 -6.25 = 0 (x+4.5)^2 = 6.25 x+4.5 = +- 2.5 x = -4.5 +- 2.5 The x-intercepts are (-2) and (-7)

None of the two, actually. However, the domain is related to the independent variable, as it is the set of all the "permitted" values for the independent variable to assume.

2016年10月21日 · From Pythagoras, we have: #sin^2 theta + cos^2 theta = 1# If #x in [-1, 1]# and #theta = arccos(x)# then:. #theta in [0, pi]#

2017年8月3日 · If #y# varies jointly as #x# and #z#, we can write this as. #y = kxz# where #k# is the constant of proportionality (we'll be finding this) In the situation, we're given that #y = 6# when #x = 4# and #z = 2#, so let's plug those in: #6 = k(4)(2)# #k = 3/4#

2016年4月5日 · x+5, remainder = 3 Look at the first terms of the divisor and the dividend, x and x^2. When x is multiplied by x, we get x^2. This x is the first term of the quotient. This x is multiplied by divisor, x-4 and subtracted from the dividend. We are now left with 5x - 17. Follow the same method, as above, to find the next term of the quotient. Since no more x terms …

2018年3月23日 · int 1/x^4color(white)(.)dx = -1/(3x^3) + C Note that: d/(dx) 1/x^3 = d/(dx) x^(-3) = -3 x^(-4) = -3(1/x^4) So: int 1/x^4color(white)(.)dx = -1/(3x^3) + C

2017年9月29日 · Forces of 3.0 N and 4.0 N act at right angles on a block. What should be the mass of the block for the acceleration to be 1 m/s^2 ?
