Answer:

3√(5) - 4

Step-by-step explanation:

a^2 - 2ab +b^2 = (a-b)^2

√(61-24√5)

= √((4-3√5)^2)

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)

Speed (mph)
nevsk [136]

Answer:

C

Step-by-step explanation:

In this question, we are asked to calculate the interquartile range of the speed values given in the question.

Firstly, we need to order the values of the speed from the lowest to the highest. That would be;

55 58 65 66 70 72 81

Now, we determine the first quartile position which is Q1. That would be (N+1)/2 where N is the number of data points which is 7 according to this question

We have (7 +1)/4= 8/4= 2

The value at the 2nd position counting from left is 58

For the third quartile , Q3, we have 3 * (N+1)/4 = 3 * 2 = 6

The value at the 6th position counting from left is 72

mathematically, the formula for the interquartile range is Q3 - Q1 = 72 - 58 = 14
