yKpoI14uk [10]

Pairs which is Adjacent side for quadrilateral MOLE is given below.

Step-by-step explanation:

Given:

Quadrilateral MOLE

Pair of adjacent sides of the quadrilateral.

Adjacent sides have one vertex common.

Option A: MO and LE

These sides does not have common vertex.

MO and LE are opposite sides in the quadrilateral MOLE.

It is not true.

Option B: EO and ME

In the quadrilateral, ME is not a side.

So it is not true.

Option C: LE and OL

In the quadrilateral, OL is not a side.

So it is not true.

Option D: ML and LE

Consider the exponential function
evablogger [386]

<u>Given</u>:

The given function f(x)=19,000 \cdot 0.96 ^x which models the value of Mark’s car, where x represents the number of years since he purchased the car.

We need to determine the approximate value of Mark's car after 7 years.

<u>Value of the car:</u>

The value of the car after 7 years can be determined by substituting x = 7 in the function f(x)=19,000 \cdot 0.96 ^x, we get;

f(7)=19,000 \cdot 0.96 ^7

f(7)=19,000 \cdot 0.7514474781

f(7)=14277.502

Rounding off to the nearest dollar, we get;

f(7)=14278

Thus, the approximate value of Mark's car after 7 years is $14278.

Hence, Option a is the correct answer.
