0.25 x 40,000 = - $10,000 ( lose )
0.35 x 0 = 0 ( break even )
0.4 x 30,000 = +$12,000 ( profit )
$12,000 - $10,0000 = $2,000
Answer:
A ) The expected value is $2,000, so the company should proceed with a project.

How do you solve this pls

solong [7]

Step-by-step explanation:

The equation of a exponential function is

$a \times (b) {}^{x}$

where a is the y value of the y intercept, b is the constant rate of change.

Here the y intercept is (0,4), the y value of the y intercept is 4.

So a=4

The graph passes through point (1,2) so

$h(x) = 4 \times b {}^{x}$

Plug in 1 for x, 2 for h(x)

$2 = 4 \times {b}^{1}$

Anything to the first power is itself so

$2 = 4 \times b$

Isolate b.

$\frac{1}{2} = b$

So our function is

$4 \times ( \frac{1}{2} ) {}^{x}$

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.
