Yeah, it’s all about calculating probabilities here. The probability on getting a 1 or 2 on a cube is 1/3 (2 options out of 6 total), whereas the other two options are either 50% or greater.

Answer: I would say rolling a number cube

Step-by-step explanation:

when flipping a coin you will have a 1/2 chance of landing on heads and then when spinning the spinner you would have a 3/4 chance since there is 3 numbers greater then 1 and then with the cube since it has 6 sides and your only getting 1 or two you would have a 2/6 chance.

A particle is moving with acceleration a ( t ) = 18 t + 16 . Its position at time t = 0 is s ( 0 ) = 10 and its velocity at time

MatroZZZ [7]

Answer:

$s(8)=2186$

Step-by-step explanation:

A particle is moving with acceleration modeled by the function:

$a(t)=18t+16$

We are given that its position s(t) at t = 0 is 10 and that its velocity v(t) at t = 0 is 16.

And we want to find its position at t = 8.

Velocity is the integral of the acceleration. Hence:

$\displaystyle v(t)=\int a(t)\, dt=\int 18t+16\, dt$

Find the velocity. Remember the constant of integration!

$v(t)=9t^2+16t+C$

Since v(t) is 16 when t = 0:

$(16)=9(0)^2+16(0)+C\Rightarrow C=16$

Hence, our velocity is given by:

$v(t)=9t^2+16t+16$

Position is the integral of the velocity. Hence:

$\displaystyle s(t)=\int v(t)\, dt=\int 9t^2+16t+16\, dt$

Integrate:

$\displaystyle s(t)=3t^3+8t^2+16t+C$

s(t) is 10 when t = 10. Hence:

$C=10$

So, our position function is:

$s(t)=3t^3+8t^2+16t+10$

The position at t = 8 will be:

$s(8)=3(8)^3+8(8)^2+16(8)+10=2186$

Two skateboarders start a race at the same time skateboarder A travels at a steady rate of 15 feet per second skateboarder B tra

Dmitriy789 [7]

Answer:

Step-by-step explanation:

Relative speed can play a major role in creating distance between two bodies. If the relative speed between two bodies is 0, then both the bodies are moving in the same direction with a similar speed. Thus, After 4 minutes, 1680 feet farther will Skateboarder B have traveled.

Skateboarder A travels at a steady rate of 15 feet per second.

Skateboarder B travels at a steady rate of 22 feet per second.

We need to determine that after 4 minutes, how much farther will Skateboarder B have traveled.

The formula for finding the distance travelled by anybody is represented below

Time is given that is 4 minutes which means 240 seconds.

Thus,

Distance travelled by skateboarder A

Distance travelled by skateboarder B.

Therefore, the separation of the distance between both the skateboarders is 5280 - 3600 = 1680.

Thus, After 4 minutes, 1680 feet farther will Skateboarder B have traveled.
