Find a vector equation and parametric equations for the line. (use the parameter t.) the line through the point (1, 0, 9) and perpendicular to the plane x + 2y + z = 7

r=<1,0,9>+t<1,2,1>

and

x=1+t

y=2t

z=9+t

Step-by-step explanation:

A vector perpendicular to the plane :

is given by (a,b,c)

So a vector perpendicular to given plane will have :

(1,2,1)

..

the answer is c)8

step-by-step explanaction:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
