2. Cross out the equations that are NOT linear functions.

wel

Welcome to the concept of the maths.

Here, we can see, that Linear equation always have highest power or degree of its variable as '1' ,

thus here, y = 3/x has degree as -1 and y = x^2 +5 has degree 2 ,

hence,

The equations that are NOT linear are

2.) y = 3/x and 5.) y = x^2 + 5

Find the equation of the line tangent to the graph of x(t)=t²+1 and y(t)=

WARRIOR [948]

Answer:

The equation of the straight line

x - 24y + 38 =0

Step-by-step explanation:

Step(i):-

Given that x(t) = t²+1 ..(i)

and y(t) = √1+t ..(ii)

Differentiating equation(i) with respective to 't'

$\frac{dx}{dt} = 2t$

Differentiating equation(ii) with respective to 't'

$\frac{dy}{dt} = \frac{1}{2\sqrt{1+t} }$

Step(ii):-

The slope of the tangent

$m = \frac{dy}{dx} = \frac{\frac{dy}{dt} }{\frac{dx}{dt} } = \frac{\frac{1}{2\sqrt{1+t} } }{2t}$

$m =( \frac{dy}{dx} )_{t=3} = \frac{1}{4(3)\sqrt{1+3} }$

$m = \frac{1}{24}$

Step(iii):-

Point x = t²+1 = 3²+1 = 10

y = √1+t =√1+3 = √4 =2

The point on the tangent line is ( 10 ,2)

The equation of the straight line

$y - y_{1} = m( x-x_{1} )$

$y - 2 = \frac{1}{24} ( x-10 )$

24 (y-2) = x-10

24y - 48 = x-10

x - 24 y -10 +48 =0

x - 24y + 38 =0

Final answer:-

The equation of the straight line

x - 24y + 38 =0
