Sergio039 [100]

Answer:

Step-by-step explanation:

Firstly  you would add up all the percentages, but it's a pie chart so it would always equal 100%

Then you would add the percentages of baseball and basketball to get 30.2%

30.2% chance or if you want it in decimal form, just divide by 100 and you get

0.302.

percentage - 30.2% chance

decimal- 0.302/1

A mass suspended from a spring is raised a distance of 5 cm above its resting position. The mass is released at time t=0 and all
miskamm [114]

Rates of change are the change of a quantity over another.

The rate of change of the mass position at 2.1 seconds is -89.6 cm/ s

The given parameters are:

\mathbf{A = |5|} -- the amplitude

\mathbf{T = \frac 13} --- the period

The position of the mass is modeled by:

\mathbf{y= Acos(wt)}

Where:

\mathbf{w = \frac{2\pi }{T}}

So, we have:

\mathbf{w = \frac{2\pi}{1/3}}

\mathbf{w = 6\pi }

\mathbf{y= Acos(wt)} becomes

\mathbf{y = |5|cos(6\pi t)}

\mathbf{y = 5cos(6\pi t)}

Differentiate

\mathbf{y' = 5 \times -sin(6\pi t) \times (6\pi)}

\mathbf{y' = -30\pi sin(6\pi t) }

When t = 2.1, we have:

\mathbf{y' = -30\pi sin(6\pi \times 2.1) }

\mathbf{y' = -30\pi sin(12.6\pi) }

\mathbf{y' = -30\pi \times 0.9510}

\mathbf{y' = -89.6296}

Approximate

\mathbf{y' = -89.6}

Hence, the rate of change of the mass position at 2.1 seconds is -89.6 cm/ s
