A new amusement-park ride that lasts 1 minute can have up to 1200 riders per hour. How many riders can ride per minute?
hodyreva [135]

Answer:

20 riders can ride per minute.

Step-by-step explanation:

The picture says to divide to find the number of riders. If we apply this here, we can see that 1200 ÷ 60 is 20.

The reasoning behind this is:

There are 60 minutes in an hour.

If the park ride lasts a minute, then the ride can have 60 rides per hour.

The question states that the ride can have up to 1200 riders per hour, so you need to divide 1200 by 60.

1200 ÷ 60 = 20.

The population P of a small town, measured in hundreds, is modeled by the inverse of the function P−1(t) = 10ln(50t − 1000), whe
AleksandrR [38]

Using the inverse function, it is found that the equation is:

P(t) = \frac{e^{0.1t}}{50} + 20

It's initial value is 20.

---------------------------

We want to find the inverse of:

y = P^{-1}(t) = 10\ln{50t - 1000}

To do this, we <u>exchange y and t, and isolate y.</u>

Then:

10\ln{50y - 1000} = t

\ln{50y - 1000} = \frac{t}{10}

e^{\ln{50y - 1000}} = e^{0.1t}

50y - 1000 = e^{0.1t}

50y = e^{0.1t} + 1000

y = \frac{e^{0.1t} + 1000}{50}

y = \frac{e^{0.1t}}{50} + \frac{1000}{50}

P(t) = \frac{e^{0.1t}}{50} + 20

It's initial value is:

P(0) = \frac{e^{0.1(0)}}{50} + 20 = 0.02 + 20 = 20.02

Rounding, 20.

Rewrite the equation 7-y=5x+11 to standard form
Zielflug [23.3K]
Rewriting this <span>7-y=5x+11 in standard form involves only changing the order in which the terms appear:

</span><span>7-y=5x+11 becomes 5x + y  + 11 - 7 = 0, or 5x + y + 4 = 0, or 5x + y = -4.</span>
