Suppose that a particle following the given path c(t) flies off on a tangent at t = t0. Compute the position of the particle at

Svetach [21]

Answer:

(30,35,0)

Step-by-step explanation:

We are given that

$C(t)=(2t^2,t^3-4t,0)$

$t_0=3,t_1=4$

The velocity of particle, $v(t)=c'(t)=(4t,3t^2-4,0)$

Substitute $t_0=3$

$C(3)=(2(3)^2,(3)^3-4(3),0))=(18,15,0)$

$v(3)=(4(3),3(3)^2-4,0)=(12,23,0)$

The tangent line at t=3 is given by

$l(t)=c(2)+(t-3)v(3)=(18,15,0)+(t-3)(12,23,0)$

Now, substitute t=4

$l(4)=(18,15,0)+(4-3)+(12,23,0)=(18,12,0)+(12,23,0)$

$l(4)=(30,35,0)$

Hence, the position of particle at $t_1=4$ =(30,35,0)

Answer:

-17x

Step-by-step explanation:

(2x^3 - x^2) - (3x^3 - 2x^2)

(8x - 2x) - (27x - 4x)

6x - 23x

-17x

(I haven't seen many questions like this before, but I think that this may be the answer.)

Which value of x makes the open sentence true?

xeze [42]

Answer:

x=1/2 or 0.5

B. 0.5

Step-by-step explanation:

Step one: Add x to both sides

you then get the equation 7=4x+5

Step two: subtract 5 from both sides

you then get the equation 2=4x

Divide both sides by 4 to undo the multiplication.

2/4=4x/4x

you get x=2/4 which simplifies to 1/2.
