Geometry the value of X

1 answer:

8 0

Since the symbol tells us the angle is 90 degrees we know the 4x and 5x add up to make 90 degrees.
Lets use this to make and form an equation

5x + 4x = 90
9x =90 (collect the x values)
x = 10 (divide both sides 9 to find what x is)

Find dy/dx if y= (1+x)e^x^2

nasty-shy [4]

$y=(1+x)e^{x^2}\\
y'=(1+x)'\cdot e^{x^2}+(1+x)\cdot(e^{x^2})'\\
y'=1\cdot e^{x^2}+(1+x)\cdot e^{x^2}\cdot (x^2)'\\
y'=e^{x^2}+(1+x)e^{x^2}\cdot2x\\
y'=e^{x^2}(1+(1+x)\cdot2x)\\
y'=e^{x^2}(1+2x+2x^2)\\
y'=e^{x^2}(2x^2+2x+1)\\$
