If a=mg-kv2/m,find,correct to the nearest whole number the value of v when a=2.8,m=12,g=9.8 and k=8/3

RUDIKE [14]

Answer:

The value of $v$ is ± 22.729.

Step-by-step explanation:

Let be $a=m\cdot g -\frac{k\cdot v^{2}}{m}$ , the variable $v$ is now cleared:

$\frac{k\cdot v^{2}}{m}=m\cdot g -a$

$k\cdot v^{2} = m^{2}\cdot g- m\cdot a$

$v^{2} = \frac{m^{2}\cdot g - m\cdot a}{k}$

$v =\pm \sqrt{\frac{m^{2}\cdot g-m\cdot a}{k} }$

If $a = 2.8$ , $m=12$ , $g = 9.8$ and $k = \frac{8}{3}$ , the value of $v$ is:

$v=\pm \sqrt{\frac{(12)^{2}\cdot (9.8)-(12)\cdot (2.8)}{\frac{8}{3} } }$

$v \approx \pm 22.729$

The value of $v$ is ± 22.729.

Mia is rolling a pair of 6-sided dice.

tekilochka [14]

Answer:

The domain of P is given by,

{n | n ∈ N, 2 ≤ n ≤ 12}

Step-by-step explanation:

A perfect die is perfectly cubic in shape with one of the integers 1,2,3,4, 5 or 6 in each of it's 6 faces and the digits on any two faces are different.

Now, two dice are rolled and P(n) models the probability of the event that the sum on the faces of the two dice is n.

Hence, the domain of P is given by,

{n | n ∈ N, 2 ≤ n ≤ 12}
