Hello!
Answer:$295.295
Explanation:
Of the statement, we have that the price of the machine decreased 10% every year
exponentially, so in the first year it real value drops to 90% of the costs. For 5 years, It can be expressed and simplified by the following equation:
We can't use that the percent drop as a percent itself, so we are going to divide 90% by 100%, and it will give us an entire number.
![\frac{90}{100}=0,9 \\ \\ Value=Costs.(0.9)^{years}](https://tex.z-dn.net/?f=%5Cfrac%7B90%7D%7B100%7D%3D0%2C9%20%5C%5C%20%5C%5C%20Value%3DCosts.%280.9%29%5E%7Byears%7D)
By substituting we have:
![Value=500000.(0.9)^{5}](https://tex.z-dn.net/?f=Value%3D500000.%280.9%29%5E%7B5%7D)
Value: $295.245
Have a nice day!
Answer:
216
Step-by-step explanation:
180 times .2 (20 percent in decimal form) = 36
36+180=216
Answer:
Step-by-step explanation:
Saving the long, drawn out derivation of the formulas to find the x and y coordinates of the directed point, suffice it to say that it is:
x coordinate:
and
y coordinate: ![\frac{by_1+ay_2}{a+b}](https://tex.z-dn.net/?f=%5Cfrac%7Bby_1%2Bay_2%7D%7Ba%2Bb%7D)
where x1, x2, y1, and y2 are the coordinates from the given points and a and b are the numbers in the ratio, namely a = 3 and b = 4. Filling in accordingly:
the x coordinate of the directed point is
which simplifies down to -6, and
the y coordinate of the directed point is
which simplifies down to -1.
The coordinate of the point is (-6, -1). Write that down so you don't forget it.
