Oxford currently generates 45,000 tons of garbage per year. but the city is launching some recycling initiatives to bring that n

umber down. If as a result, the amount of garbage decreases by 5% each year. Is this problem exponential growth or decay? Identify the growth or decay factor.
growth, (1 + .05)
growth, (1-.05)
decay,(1+.05)
decay,(1-.05)

Answer:

-Exponential Decay

-Decay factor is (1-0.05)

Step-by-step explanation:

-Given that the number decreases by a defined rate each year from the initial size by 5%,

-This is an exponential decay function of the form:

y=Ae^{-rt}

Where:

y is the quantity/size after time t

A is the initial size

r is the rate of decay

-Our function can the be written as

y=45000e^{-0.05t}

Hence, the decay rate/factor is 0.05

#Alternatively

The exponential decay can be of the form:

y=ab^x

Where:

y is the size at time x, a is the initial size, x is time and b is the decay factor.

b is of the form b=(1-r),\ \  r=decay\  rate

y=ab^x\\\\y=45000(1-0.05)^x

Hence, the decay factor is (1-0.05)

Log(1+y) - log(1-y) = log x in 2 decimal places, express y in terms of x
GaryK [48]

Answer: y = \frac{x-1}{x+1}

Step-by-step explanation:

log(1+y) - log(1-y) = log x \\log\frac{1+y}{1-y} =log x\\x = \frac{1+y}{1-y}\\x(1-y)=1+y\\x-xy=1+y\\x-1 = xy+y\\y(x+1)=x-1\\y=\frac{x-1}{x+1}

How can 1% of 300 be used to determine 64% of 300? Enter your answers in the boxes to correctly complete the statement. 1% of 30
Ratling [72]

Answer:

1% of 300 is 3 so if you multiply that 3 by 64, you get 192 which is also 64% of 300

Step-by-step explanation:

.01 x 300 = 3

3 x 64 = 192

.64 x 300 = 192
