Which expression is equivalent to

cestrela7 [59]

Answer:

Step-by-step explanation:

When 3 is squared, it becomes 9. That means that both A and B are incorrect.

The powers on u and v are doubled not added to become u^6 and v^8 so that makes C the only possible answer.

Si un proyectil asciende verticalmente, y después de 3 segundos alcanza su altura máxima, calcule la velocidad que lleva a la mi

lys-0071 [83]

Answer:

The speed is 20.8 m/s

Step-by-step explanation:

If a projectile ascends vertically, and after 3 seconds it reaches its maximum height, calculate the velocity that it carries to the middle of its downward trajectory

Let the maximum height is h and initial velocity is u.

From first equation of motion

v = u + at

0 = u - g x 3

u = 3 g.....(1)

Use third equation of motion

$v^2 = u^2 - 2 gh \\\\0 = 9 g^2 - 2 gh \\\\h = 4.5 g$

Let the speed at half the height is v'.

$v^2 = u^2 + 2 gh \\\\v'^2 = 0 + 2 g\times 2.25 g\\\\v'^2 = 4.5\times 9.8\times9.8\\\\v' = 20.8 m/s$

Given f (x) = 6x + 2, find f (x + 3).

Dovator [93]

Answer:

6x+20

Step-by-step explanation:

If f(x)=6x+2 and you are asked to find f(x+3), then you just replace all the x's in f(x)=6x+2 with (x+3).

Doing this gives you:

f(x)=6x+2 with new input (x+3) in place of out input (x)

f(x+3)=6(x+3)+2

f(x+3)=6x+18+2

f(x+3)=6x+20
