Answer:

It's Option A.

Step-by-step explanation:

Using the Cosine Rule:

cos < K = (3.9^2 - 1.9^2 - 2.8^2) / (-2 *1.9*2.8)

= 3.76 / -10.64

= - 0.3534.

m < K = 110.7 degrees.

Using the Sine Rule:

3.9 / sin 110.7 = 2.8 / sin <J

sin J = 2.8 sin 110.7/ 3.9 = 0.6716

m < J = 42.2 degrees

So m < L = 180 - (110.7 + 42.2)

= 180 - 152.9

= 27.1 degrees

the current value of a new car is 18,000. the car will depreciate 15% per year over the next 5 year. which exponential equation

Arte-miy333 [17]

The exponential equation that models this situation is:

$V(t) = 18000(0.85)^t, 0 \leq t \leq 5$ .

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

For this problem, the parameters are:

A(0) = 18000, r = 0.15.

Hence the equation for the value of the car over the next 5 years is:

$A(t) = A(0)(1 - r)^t$

$A(t) = 18000(1 - 0.15)^t$

$V(t) = 18000(0.85)^t, 0 \leq t \leq 5$ .

Answer:

<em>Probability ≈ 0.3571</em>

Step-by-step explanation:

Consider the steps below;

$Total Number of Outcomes - 9C4,\\9 ! / 4 ! * ( 9 - 4 ),\\9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / 4 * 3 * 2 * 1 * 5 * 4 * 3 * 2 * 1,\\\\Total Outcomes = 126,\\\\Number of Outcomes - 3C2 * ( 6C2 ),\\3C2 = 3,\\6C2 = 15,\\\\Number of Outcomes = 3 * 15 = 45,\\\\Probability; 45 / 126 = ( About ) 0.3571$

<em>Solution; Probability ≈ 0.3571</em>
