The two solutions are:
<h2>
Explanation:</h2>
Here we have the following equation:
To write this quadratic equation in Standard form, let's subtract 18 from both sides, so:
The problem states:
<em>Solve for a using the quadratic formula </em><em>or</em><em> completing the square.</em>
So, let's choose the quadratic formula:

we are given the ordinary differential equation of dy/dx = 2y+1. The ODE is variable separable which means x and y can be grouped altogether explicitly. In this case, the equation becomesdy / 2y + 1 = dx
1/2 ln (2y + 1) = x + ln Cln (2y + 1) = 2x + ln C2y + 1 = C e 2x y = (C e 2x - 1)/2
The ODE y' + xy = x can be grouped into y' + x(y-1) = 0 'y' / y-1 = -xThis is variable separable
Answer:
1. C points radially outward from origin
2. A. Points radially outward from z origin
3. D. Radially inwards toward origin
4. B. Inwards towards the z axis
Step-by-step explanation:
1.
X²+y²+z² = f(x,y,z)
Vector P<x,y,z>
2<x,y,z> = 2p
The answer is c points radially outward from origin
2.
X²+y² = f(x,y)
<2x,2y,0>
Points radially outward from z axis
3.
D. Points radially inwards toward origin
4.
B. Points radially inwards toward the z axis.
