To determine the types and number of roots of a
quadratic equation, examine the discriminant:
• If b² - 4ac > 0 then there are two real (unique) roots
• If b² - 4ac = 0 then there is one (double) rea
1. If f(x)= 16^1/3 and g(x)=2x^-2/5
what is f(x) * g(x)
What is f(x)/g(x)
2. The Volume of a sphere can be given by the V= 4.18879r^2. You have to design a spherical container that will hold a volum
[6x+9]+[-5]
im confused, so please help?-The thing around the -5 is the absolute value sign right?
[6x + 9] + [-5]
[6x + 9] + 5
[6x + 9]
6x + 9 -8
6x -17
x -17/6-Just so you know the ABS sign
I need to obtain the derivative of:
p(θ) = (π/2)^ Sinθ
Please be clear with your answer, and how you got to it so I may understand :)-Its easier if you take log of both sides, then differentiate:
p(
Joran,
Algebra is fun!
Algebra is the branch of mathematics concerning the study of the rules of operations and relations, and the constructions and concepts arising from them, including terms, poly
what is the insection points for
x=0.56siny
x=1.8siny
within the range of 0 to 10
Thanks
ps please show working outs-0.56siny=1.8siny
The only way this is possible is where sin(y)=0.
the altitude to that side must be....?????????-2 cm-Area = 1/2 base * height
12 = 1/2 * 6 * altitude to side of length 6
12 = 3 * altitude
altitude = 12/3
altitude = 4 cm-3 cm-4cm
Any tips on becoming a math wiz?? thnks pplz.-Joran, here are a few tips...
1. If you are still in school, pay attention in class and do all of your homework.
2. Register to play games on math website
how do I work out the point of which these two equations intersect
y=log(-2501)
x=1.9siny
thanks
please show working out, and the coordinate you got in the end-You cant take the logarithm of a negat
I need help w/ figuring out how to do this problem, so a step-by-step answer would be wonderful. Do i do long division? Thanks!-∫ (x^4-3x³ - 4x² + 29x - 44) / (x² - 9) dx
= ∫ x² - 3x + 5 dx + ∫ (2x +
The answer is is 19%.
But I have NO IDEA how to get that answer. Could someone please explain it to me?
10 points for the effort.-input something for the radius say 5
area = pie R(squared)
so 3.14
Which of the following is equivalent to (√csc^2 x-1) / (√sec^2 x -1)? MULTIPLE CHOICE?
a) tan^4 x
b)cot^4 x
c)2_cotx
d)tan^7 xn-Work it out by using basic trigonometric properties and identities:
csc
Use the definition of continuity and the properties of limits to show that the function is continuous at the given number a.
f(x)= (x+2x^3)^4, a=-1.
PLEASE HELP ME WITH THIS PROBLEM. THANK YOU!-If f
so... i dont get this question on a hadnout i got:
Explain why x^4 + 7x^2 + x - 5 = 0 must have a root interval [0,1] , (0≤x≤1)
and this one:
Let f be a linear function where f(2) = -5 and f(-3) =
if A is singular , then all splittings A = S - T must fail. From Ax = 0, show that S-1Tx = x. So this matrix B = S-1T has ? = 1 and fails.-A = S-T
Ax = 0==>(S-T)x = 0==>Sx = Tx==>x = S^(-1)T x==>x =
