y = 10 × 5³ = 10 × 125 = 1250
Answer:
(-5, 4)
Step-by-step explanation:
To find the new coordinate, subtract 8 from the x value and add 7 to the y value:
3 - 8 = -5
-5 will be the new x coordinate
-3 + 7 = 4
4 will be the new y coordinate
So, the coordinate K will be (-5, 4) after the translation
Answer:
To the nearest hundred dollars, the car will be worth $17,900 by 2005
Step-by-step explanation:
Firstly, we need to write the depreciation equation
We have this as:
V = I(1 - r)^t
V is the present value which is what we want to calculate
I is the initial value, the amount the cad was bought which is $22,000
r is the rate of change which is 5% = 5/100 = 0.05
t is the time difference which is 2005-2001 = 4
Substituting all these into the depreciation equation, we have it that
V = 22,000(1 -0.05)^4
V = $17,919.1375
To the nearest hundred dollars, that would be;
$17,900
