# Find the value of ALL the other five trigonometric functions, given tanx= 4/11, secx<0. (answer)

Well if we use the trigonometric functions   sin X = opposite / hypotenuse cos X = adjacent / hypotenuse tan X = opposite/ adjacent csc X = hypotenuse / opposite sec X = hypotenuse/adjacent ctn X = adjacent/opposite   We know that the hypotenuse = sqrt(adjacent2 +...

# 2/3 cups of oat meal make 10 granola bars how many granola bars get made with 20 cups of oatmeal (answer)

We know from the first statement that 2/3 cup oat meal ⇒10 granola bars   now we know we have 20 cups of oatmeal how many granola bars can be made.    If you think of this as two equivalent ratios we can set up the following equation   2/3 cup...

# solve the equation log2 x + logx 2 =2.5 (answer)

if you remember that if you were going to change base of a log   logb(x) = logd(x) / logd(b)   if we used this principle with your eqn   log2x + logx2 = 2.5   we could get the eqn into on base   ln(x)/ln(2) + ln(2)/ln(x) =...

# where do i have to got to learn and understand mathemetics (answer)

I am assuming you're asking where you can go to learn and understand mathematics.   There are several websites that are useful You can use this website, they have some nice explanations for different levels of math under the resources at the top of the page, or you can go directly...

# Write p(x)=3x^2+4x-1 in p (x)=a(a-h)^2+k form using complete the square method (answer)

p(x) = 3x2 + 4x -1 p(x) - a(a-h)2 - k  ( think you mean p(x) = a(x+d)2 + e   Since in our eqn  the coefficient of the x2 term is not 1, we need to divide out the 3 by multiplying by 3/3   p(x) = (3x2 + 4x - 1)3/3 p(x) = 3( x2+ 4x/3...

Chris,    Energy   Here is an explanation from Yahoo Questions that really answers your question   Chemical Energy: is stored in the bonds of the chemical they are holding together. Covalent bonds contain the most energy,while hydrogen bond much less....

# HELP ME OUT PLEASE SOLVE IT ......................................................application of system equation (answer)

Ibadan,   I already answered questions 2 or 3 on previous post   I will help set up the problems by helping you get the eqns but I will leave the solving to you   In all word problems you need to list the information you have and assign variables to those that...

# Applications of system of equation (answer)

(1)The best thing to do with word problems is list all the info you have and need assigning variables   it = total money invested = 5500   if1 = amount invested in fund 1 if2 = amount invested in fund 2 = it - if1 = 5500 - if1   pf1 = profit fund 1 = 8%...

# Simplify. Assume all variables represent positive real numbers (answer)

If you remember,  a√x = x1/a and x(a•b) = (xa)b   we can take your eqn 3√x6y5   and convert it to    3√x6y5 = (x6y5)1/3= x6/3 y5/3    x6/3  simplifies to x2 because 6/3 = 2 y5/3  simplifies to y(3√y2) ...

# how do you solve ln(x+1)-ln(x)=ln4 (answer)

ln(x+1) -ln(x) = ln(4)   if you remember the basic rules of logs   1) logb(mn) = logb(m) + logb(n) 2) logb(m/n) = logb(m) – logb(n) 3) logb(mn) = n · logb(m)   So if we look at your eqn, we can use rule 2    ln(x+1)...

# How do I solve this dividing monomials problem? (answer)

(m-2)(n-5)/((m4)(n3)-1)   you could also notice that the denominator is also to the -1 power which means that it becomes part of the numerator   1/x = x-1 1/x-1 = x   (m-2)(n-5)/((m4)(n3)-1) =(m-2)(n-5)(m4)(n3)= (m-2)(m4)(n-5)(n3)   you...

# What generalization can you make about the length of the third side and the difference of the lengths of the other two sides? (The triangle inequality theorem (answer)

lets assume the lengths of the sides of your triangle are A, B and C   if we take the triangular inequality theorem A < B + C   if we subtracted B from both sides we would get   A - B < C   now if we want to generalize this you could...

# How do i factor a binomial when one term is cubed? (answer)

Yes it is possible.   Actually both of the terms in the equation are cubed.   27x3 = (3x)3  and (-1) = (-1)3= (-1)(-1)(-1)  = 1(-1) = -1  or (1)3 = 1   realizing this we can use formula for (a3 - b3) = (a-b)(a2 + ab + b2) in your...

# True or false The y - intercept of the straight line with equation Ax + By + C = O is - CIB (B'O). (answer)

Ruben,   first lets think what the y intercept is. It is the value of y when x is 0.   So what we would need to do is substitute x=0 into the given equation and then solve for y.   Given:Ax+By + C = 0 A(0) +By +C = 0      ...

# how to you turn a decimal into a fraction (answer)

# find the equation of a parabola whose focus is at (0,-2) and directrix at y=4 (answer)

The vertex is always halfway between the focus and the directrix, and the parabola always curves away from the directrix.   so if the focus is at (0,-2) and the directrix is at y = 4 the vertex would be halfway between here   So the vertex, exactly between the focus...
