Calculus problem, Find an equation of the tangent line to the graph of the function 2x^2-5xy+3y^3-32=0 at-1,2

((2x)^(2))-((5)(xy))+((3)(y)^(3))-(32)=0 at(-1,2) Im having trouble figuring out why exactly I only place dy/dx for -5x and 9y^2-Im assuming you did the differentiation correct and just wondering the

Help with this please?! 10 points!!!

i really cant solve this and its been bugging me. im really not a lazy person whos trying to get someone else to do my work for me but i seriously cant do this! ive thought about it but i cant think o

Calculus problem, Use logarithmic differentiation to find dy/dx for y = (3x-4)/(2x+5)^4

Hey all, need some help checking my solution for this problem: y = (3x-4)/(2x+5)^4-Ill go into more detail.. y = (3x-4)/(2x+5)^4 when using logs, division switches to subtraction ln y = ln (3x-4)

Find the distance between the pair of points (-7,2) and (-1,6)

use the formula:D = √(x2-x1)² + (y2-y1)² just your points into it so:D = √(-1- -7)² + (6-2)²D = √(6)² + (4)²D = √(36 + 16)D = √(52)D = 7.211-(36+16)^1/2 = 7.21 =) Good luck with your math-4^2+6^2=52

What is the remainder when x³ + ax² + 2x + 9 is divided by x + 1

Whenx³ + ax² + 2x + 9 is divided by x - 1 the remainder is 7. What is the remainder when x³ + ax² + 2x + 9 is divided by x + 1? So I know we add the opposite I thought, to get P(-1) = (-1)³ +a(-1)²+2

Is it true that if algebra was easier the geometry is going to be harder

And vise versa? I think i spelt the wrong, whoops. Thanks (:-Is it true that if pigs fly then you should always carry an umbrella? Your question makes as much sense. Most students find geometry ha

Help with Complex Numbers problems

I have an exam tomorrow and our teacher gave us some revision questions on complex numbers. There were three that I could not do and we did not have time in class to solve them. Here they are: 1) When

How to do this modulus qestion

Solve for x 4|x| + |2x -2| = |3x -3| ans: 1/5 and- 1/3-_______________________ 4|x| + |2x -2| = |3x -3||4x| + 2|x -1| = 3|x -1||4x| = 3|x -1| -2|x -1| |4x| = |x -1|← This is true only if 4x and x-1 a

Coordinate Geometry????

The coordinates of ABC are A(1,5), B(4,4) and C(8,6). Given that P is the foot of the perpendicular from A to BC find the coordinates of P and equation of AP i tried to use the midpoint formula for P

Multiply and simplify by factoring √6 x √14

√6 x √14= √84=√4√21= 2√21

F'(x) is an even function, state the correct answer:

State the correct answer: f(x) is an even function with domain all real numbers which is continuous for all values of x and differentiable for all values of x A- f(x) is always an odd function B- f(x

Simplify by factoring √40

First thing is to find a pair of numbers that will multiply to 40, but one of them must be a square number. In this case it would be √10√4 Notice √4 = 2 Therefore we have 2√10 -------------- Sor

... Its height above the ground (h) in meters at any time (t) in seconds is given by the equation: h = -4.9t^2 + 98t + 100 How long (rounded to the nearest hundredth of a second) will it take the pr

Determine quotient for 5x³-6x²+64 divided by x+2

so i used synthetic division to get 5-1696 which would make 5x²-16x as my quotient with 96 as a remainder, but the answer shows 5x²-16x+32 Even if my 96 were to be part of the quotient I cant get a ne
