Answer:
∛27 = 3
Step-by-step explanation:
A radical is simply a fractional exponent:
Hence, ∛27 =
Since 27 = 3³, then:
You could rewrite ∛27 as ∛(3)³.
Multiplying the fractional exponents (3 × 1/3) will result in 1 (because 3 is the <u><em>multiplicative inverse</em></u> of 1/3). The multiplicative inverse of a number is defined as a number which when multiplied by the original number gives the product as 1.
Therefore, ∛27 = 3.
Answer:
a. y-intercept = 23350 and x-intercept = 13
b.
c.
Step-by-step explanation:
Given
Solving (a): The x and y intercepts
The y intercept is the initial depreciation value
i.e. when x = 0
This value is the value of the car when it was initially purchased.
Hence, the y-intercept = 23350
The x intercept is the year it takes to finish depreciating
i.e. when y = 0
From the question, we understand that it takes 13 years for the car to totally get depreciated.
Hence, the x-intercept = 13
Solving (b): The slope
The slope (m) is the rate of depreciation per year
This is calculated by dividing the total depreciation by the duration.
So:
Because it is depreciation, it means the slope represents a deduction.
So,
Solving (c): The straight line equation
The general format of an equation is:
Where
In (a), we have that:
In (b), we have that:
Substitute these values in
<em>Hence, the depreciation equation is: </em><em></em>
