How do I solve this problem because I don’t understand

Citrus2011 [14]

You are using a^2+b^2=c^2
since c is the hypotenuse

#1 the equation would be 16^2+b^2=34^2
16^2= 256
34^2= 1156
1156-256= 900
b^2=900 (now find square root of 900)
b= 30

You are now trying to find the hypotenuse or c in this so it is simpler

#2 equation - 4^2+2^2=c^2
16+4=c^2
20=c^2
c= 4.27

Or which equation would x = 4 be a solution?

ElenaW [278]

$2x+7=22\ \ \ \ |-7\\2x=15\ \ \ \ \ |:2\\x=7.4\neq4\\----------------------\\6x\div8=3\ \ \ \ |\cdot8\\6x=24\ \ \ \ |:6\\x=4\\-------------------\\8-3x=20\ \ \ \ |-8\\-3x=12\ \ \ \ |:(-3)\\x=-4\neq4\\---------------------\\2x+8=4\ \ \ \ \ |-8\\2x=-4\ \ \ \ \ |:2\\x=-2\neq4\\\\Answer:\ 6x\div8=3$

Other method.

Enter the value of x for each equation and check the equality of the pages of the equation

$2x+7=22\\L=2(4)+7=8+7=15;\qquad R=22\qquad L\neq R\\\\6x\div8=3\\L=6(4)\div8=24\div8=3;\qquad R=3;\qquad L=R\\\\8-3x=20\\L=8-3(4)=8-12=-4;\qquad R=20;\qquad L\neq R\\\\2x+8=4\\L=2(4)+8=8+8=16;\qquad R=4;\qquad L\neq R$

Using separation of variables technique, solve the following differential equation with initial condition y'= e sinx and y(pi) =

inessss [21]

$\begin{aligned}&y'=e^y\sin x\\&\dfrac{dy}{dx}=e^y\sin x\\&\dfrac{dy}{e^y}=\sin x\, dx\\&\int \dfrac{dy}{e^y}=\int \sin x\, dx\\&-e^{-y}=-\cos x+C\\&e^{-y}=\cos x+C\\\end$

$e^{-0}=\cos \pi +C\\1=1+C\\C=0\\\\\boxed{\boxed{e^{-y}=\cos x}}$
