The initial value of a quantity Q (at year t = 0) is 112.8 and the quantity is decreasing by 23.4% per year. a) Write a formula

Svetach [21]

Answer:

a) $Q(t) = 112.8*(0.766)^{t}$

b) When t = 10, Q = 7.845.

Step-by-step explanation:

The value of a quantity after t years is given by the following formula:

$Q(t) = Q_{0}(1 + r)^{t}$

In which $Q_{0}$ is the initial quantity and r is the rate that it changes. If it increases, r is positive. If it decreases, r is negative.

a) Write a formula for Q as a function of t.

The initial value of a quantity Q (at year t = 0) is 112.8.

This means that $Q_{0} = 112.8$ .

The quantity is decreasing by 23.4% per year.

This means that $r = -0.234$

$Q(t) = 112.8*(1 - 0.234)^{t}$

$Q(t) = 112.8*(0.766)^{t}$

b) What is the value of Q when t = 10?

This is Q(10).

$Q(t) = 112.8*(0.766)^{t}$

$Q(t) = 112.8*(0.766)^{10} = 7.845$

When t = 10, Q = 7.845.

Solve for x . Round to the nearest tenth if necessary

san4es73 [151]

Answer:

Step-by-step explanation:

Formula:

$\cos \alpha =\frac{\text{adjacent} }{\text{hypotenuse} }$

Then

$\cos \left( 22\right) =\frac{56}{x}$

Then

$x =\frac{56}{\cos(22)}$

$=60.397945589945$

ECONOMICS 1.03<br> justify the choice you make based on a costs and benefits analysis

ahrayia [7]

Cost and benefit analysis is where you compare the benefit you receive to the cost you pay.

For example: going to a movie costs $30. The benefit is seeing the movie you’ve been wanting to see. If you go to the movie you analyzed that the benefit is greater than the cost. If you stayed home, you analyzed that the cost is greater than the benefit.
