Suppose you need to know an equation of the tangent plane to a surface S at the point P(4, 1, 4). You don't have an equation for
Alex777 [14]

Answer:

15x-8y+9z=88

Step-by-step explanation:

We are given that

Equation of curves

r_1(t)=

r_2(u)=

Both curves lie on S.

We have to find the equation of tangent plane at P(4,1,4).

r'_1(t)=,r'_2(u)=

r_1(0)=, r_2(1)=

Hence, t=0 and u then it satisfied the given point.

Substitute the values in the derivatives

r'_1(0)=,r'_2(1)=

r'_1(0)\times r'_2(1)=\times =

The equation of tangent at point P(4,1,4) is given by

30(x-4)-16(y-1)+18(z-4)=0

30x-120-16y+16+18z-72=0

30x-16y+18z=176

15x-8y+9z=88

Graph the equation <br><br>2x + 3y = 9
jeka57 [31]

2x + 3y = 9\\3y = -2x + 9\\y = -\frac{2}{3}x + 3

Look at the graph picture I attached

y = mx + c

c is the intercept, which is why the graph crosses the y-axis at +3

to find where it crosses the x-axis, we make y = 0

y = 0\\\to -\frac{2}{3}x + 3 = 0\\-\frac{2}{3} = -3\\\frac{2}{3}x = 3\\2x = 9\\x = \frac{9}{2}\ \ (=4.5)
