Answer:
The have the wrong values.
Step-by-step explanation:
The point (-7,-24) lies in the third quadrant, where the only tangent function will have a positive value and all the other trigonometric functions are negative.
The origin has a distance from the point is .
If the point makes an angle with the negative x-axis, then
Therefore, the have the wrong values. (Answer)
<u>Solution-</u>
The company purchased a new computer for $1500 and chooses to depreciate using the straight-line method for 5 years.
a-
As the value is depreciating, so its slope will be -ve.
( ∵ The value of 1500 will depreciate in 5 years )
y-intercept = 1500 ( ∵ At the beginning when x=0, y=1500)
Linear equation of the system,
y = mx +c ,
where,
m = slope = -300,
c = y-intercept = 1500
Putting the values,
b-
The implied domain of the function is 1≤x≤5 or [1,5]
c-
Follow the attachment attached herewith for the graph.
d-
Here,
y = the value of the computer
.
x = number of years depreciated = 3
Putting the values in the linear equation,
y = 1500-300(3) = 1500-900 = 600
∴ The book value of the computer after 3 years is $600.
e-
Here given that,
y = value of computer = 1600
x = asked = ??
Putting the values in the equation,
1600 = 1500 - 300x
⇒ 100= -300x
⇒ x= -3
∴ As the x is in negative, i.e it is impossible for the computer to be worth of 1600. It happens also because as the value is depreciating, it will always be less than 1500.
