<u>Given</u>:
The given function 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 , we get;
Rounding off to the nearest dollar, we get;
Thus, the approximate value of Mark's car after 7 years is $14278.
Hence, Option a is the correct answer.
Answer:
<em>a. 2,520,000.00</em>
<em>b. $1,942,017.51</em>
<em>c. $577,982.49</em>
Step-by-step explanation:
<u>Distances in a Rectangle</u>
a.
Running the cable along the edges of the field would need a total length of 860 ft + 340 ft = 1,200 ft of cable. The unit cost of the cable is $2,100 per foot, thus the cost of the total lenght of cable was 2,100*1,200= $2,520,000.
b. If the cable ran along the diagonal, the distance must be computed by
where x = 860 ft and y = 340 ft, thus
D = 924.77 ft. The cost of the cable would be 2,100*924.77= $1,942,017.51
c. The savings if the cable were installed along the diagonal of the field instead of around the edges of the field would be
$2,520,000 - $1,942,017.51 = $577,982.49
The equation that represent the total salary that I earn for working x hours in a week is y = 10x
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on any other variable for its value while a dependent variable is a variable that depends on other variable.
Let y represent the total salary earned by working x hours, hence, if I earn $10 per hour:
y = 10x
The equation that represent the total salary that I earn for working x hours in a week is y = 10x
