Answer:
y=45000(1-0.03)^x
Step-by-step explanation:
1) the exponential decay formula is
y=c(1-r)^x
where c= starting amount
r=rate of change
x=time
so
y=45000(1-0.03)^x
y=45000-1350x
3/5 = 6/10 (which is 60%) 100% - 60% = 40%
2 ft
Step-by-step explanation:
The height from which the beach ball was thrown happens when t = 0. So setting t = 0 to get y, we get
y = [-16(0) - 2](0 - 1)
= (-2)(-1)
= 2 ft
Therefore, the ball was thrown from a height of 2 ft.
Answer: $30,000
Step-by-step explanation:
If Mr. Inahurry had a 10% loss, it means that he paid X for the house and only got back 90% (100% - 10%) of what he paid.
This way X . 90% = 27,000
X . 0.90 = 27,000
X = 27,000/0.9
X = 30,000
Counter-proof: 30,000 . 10% = 30,000 . 0.10 = 3,000
30,000 - 3,000 = 27,000
Answer:
Step-by-step explanation:
The cube root of 15,409,000 = 248.84 yards.
There are 1760 yards in a mile
One edge of a cube = 248.84 / 1760 = .141386 miles.
So a cube would be .00283cubic miles. Your answer does not reach a hundredth place, I don't think.
