Use Chain Rule 1=cos(xy^2)(y^2+2xyy') 1=cos(xy^2)y^2+(2xy)cos(xy^2)(y') [1-cos(xy^2)y^2]/[(2xy)cos(xy^2)]=y'

An effort to bring civilization with them... I just took the test. This answer is 100% correct, I promise!

Can someone explain with values for I = dQ/dt please?

2/5 of the boys don't know how to swim, so 2/5 * 1/3= 2/15 of the total people are boys who cannot swim. Likewise for girls, 3/5 * 2/3= 6/15 of the total people are girls who cannot swim. Thus, 1- 2/15 - 6/15= 7/15 of the total people are swimmers. Thus,...

15*15=225 x*x=x^2 (x+3)*(x+3)=X^2+9 225=x^2+x^2+9 225=2x^2+9 216=2x^2 108=x^2 10.39=x

v=speed x=time The v1 for first bus is 44mi/h, v2 for second bus is 48mi/h. We want to find the time it takes for the distance between those two buses reached 274mi. The second bus departs after the first bus traveled for one hour. So the distance between...

5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13 -15x-10 -x+3 = -16x-20+13 -16x-7=-16x-7 For - (x - 3), imagine this to be - 1*(x - 3),multiple -1 to x, and multiply -1 to -3. That will turn out to be equal to -x+3.

n^2-49=0; expand to (n-7)(n+7)=0; thus, n-7=0 or n+7=0; n=7 and n=-7 ------------------------ n^2-49=0; n^2=49 n=± sqrt(49)

Mode: The number which appears most often in a set of numbers. So the answer is clearly D as all the numbers only appear once. BTW, the question said 6 seashells but it has only 5 numbers.

1, draw a number line you can easily see 2,it should be |-5| instead of /5/, that | | is absolute value of a number, which makes all negative number to be positive, and positive number remain positive. Thus, turn -5 to be positive 5.

It's a square lawn with area of 81, thus side length is 9. The path surround it is 1 meter wide, thus the area will be 2*11*1+2*9*1=22+18=40 --------------------------------------------------------------------------- or, as the path around the lawn, so th...

As it's 3 meters around the pool, we should add 6 to both width and length. so the total of blocks + pool is (2+6)*(3.5+6)=76, and the area of pool is 2*3.5=7, 76-7=69 which is the area of blocks. The paving blocks has an area of 0.5*0.5=0.25 The total ar...
