Answer:

11 sq.ft

Step-by-step explanation:

∅= 80×π/180= 4π/9

area= 1/2 × r²× ∅

= 1/2 × 16 × ∅

= 8∅

=8×(4π/9)

= 32π/9

= 11.17 ~11

Given the vector equation ????(t)=(4−3t)????+(−5+t)????+(3−t)????, rewrite this in terms of the parametric equations for the lin

Anit [1.1K]

Answer:

The parametric equations for the line.x(t)=

y(t)=

z(t)=

$\= r (t) = \left \{ {{x(t)= 4-3t} \atop {y(t)= -5+t}} \atop {z(t)=3-t}} \right \}$

Step-by-step explanation:

From the question we are told that

the given equation is

$\= r(t) = (4-3t) + (-5 + t) + (3-t)$

This given equation can be represented as

$\= r (t) = [4 -3t , -5+t,3-t]$

Generally this equation can be represented in terms of the parametric equations as follows

$\= r (t) = \left \{ {{x(t)= 4-3t} \atop {y(t)= -5+t}} \atop {z(t)=3-t}} \right \}$

This above equation is obtained by assigning each component of r(t) to each line
