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

barxatty [35]

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)

Angle D and Angle F are supplementary. The measure of Angle D is (3x + 5), and the measure of angle F is (2x). What is the measu

olga55 [171]

Step-by-step explanation:

Two angles are called suplementary when their measures add to 180 degrees.

D+F= 180

3x+5+2x= 180

5x+5=180

5x= 175

x= 35°

angle D = 3x+5= 3(35)+5= <u>110°</u>

remember
x^-m=1/(x^m)

so

The mean of the values in a data set is c. If each of the values in the data set were multiplied by 6, what would be the mean of

oksian1 [2.3K]

Answer:

Mean of the data would be 6c

Step-by-step explanation:

<u>Rule to Remember:</u> Whenever each term of the data is multiplied by the same number, the new mean is previous mean multiplied by that number.

In this case, original value of mean was c. Each value of the data is multiplied with 6 so a result the new mean would be 6 times the original mean i.e. 6c

Let us consider that original values in the data set are x, y and z. Their mean would be:

$Mean=\frac{x+y+z}{3}$

If each value of the data is multiplied with 6, the new values would be 6x, 6y and 6z. The mean in this case will be:

$Mean=\frac{6x+6y+6z}{3}\\Mean=\frac{6(x+y+z)}{3}\\Mean=6\times\frac{x+y+z}{3}\\Mean=6c$

We can see from above that the new mean is 6 multiplied to the original mean.

Therefore, the answer to this question is 6c.
