Angle V is 40. Angle V and Y are congruent. The angles of a triangle are a sum of 180. Angle V and Angle Y add up to 80. Therefore angle VWZ is 100

Answer:

This means that the correct initial value problem for the population p(t) as a function of time is is $P(0) = 1000$

Step-by-step explanation:

The population of a town increases at a rate proportional to its population:

This means that this situation is modeled by the following differential equation:

$\frac{dP}{dt} = kP$

In which k is the growth rate.

By separation of variables, the solution is given by:

$P(t) = P(0)e^{kt}$

In which P(0) is the initial population.

Initial population of 1000.

This means that the correct initial value problem for the population p(t) as a function of time is is $P(0) = 1000$

In stage 2 of a rocket's takeoff, the speed of the rocket increases at a rate of 4.3% per minute. The speed of the rocket at the

Sveta_85 [38]

The correct option is: B. $25000=5000(1.043)^t$

Explanation

The general form of growth equation is: $A=P(1+r)^t$ , where A = final amount, P = initial amount, r = growth rate in decimal form and t = time duration

Here, the speed of the rocket at the beginning was 5,000 kilometers per hour and at the end will be 25,000 kilometers per hour. The speed increases at a rate of 4.3% per minute.

That means, $A= 25000 , P= 5000, r= 4.3\% = 0.043$

Now plugging these values into the above equation, we will get......

$25000=5000(1+0.043)^t\\ \\ 25000=5000(1.043)^t$

So, the equation that could be used to determine the time for the speed of the rocket to reach 25,000 kilometers per hour will be: $25000=5000(1.043)^t$
