Answer:

A = 113.14 in^2

Step-by-step explanation:

The circumference is given by

C = 2 * pi *r

37 5/7 = 2 * 22/7 * r

Change the first number to an improper fraction

(7*37+5)/7 = 44/7 r

264 /7 = 44/7 r

Multiply each side by 7/44

7/44 *264 /7 = 44/7 r * 7/44

6 = r

Now we need to find the area

A = pi r^2

A = 22/7 * 6^2

A = 22/7 * 36

A =792/7

A =113.1428571

To the nearest hundredth

A = 113.14 in^2

Write each set of numbers in set-builder and interval notation<br><br> X&gt;50
KiRa [710]

Answer:

\{x\ E\ Z\ |\ x > 50\} ---- Set Builder

(50, ∞)  ---- Interval Notation

Step-by-step explanation:

Given

x > 50

Required

Write as a

- Set builder

- Interval notation

As Set Builder:

x > 50 means that x is an integer and x is greater than 50.

In set builder notation, integers are represented with z.

So, the above can be represented as:

\{x\ E\ Z\ |\ x > 50\}

This translates to:

x is a member of the set of integers such that x is greater than 50

As Interval Notation:

In interval notation, we make use of brackets to represent the intervals.

In this case > is represented by (a,b)

Where a and b are the intervals of the notation

Since x > 50, then a = 50 and b = ∞ because we only know the starting point and not the end point.

<em>Hence: x > 50 in interval notation is (50, ∞)</em>

Jesse takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A rat weighs
brilliants [131]

Answer:

The slope is  s = $0.1774 / pounds

Step-by-step explanation:

From the question we are told that

   The weight of the rat is w_1 =  3.5 \ pound

     The cost of feeding the rat per week is c_1 =$4.50

     The weight of a Beagle is  w_2 =  30 \ pound

     The cost of feed a Beagle per week is  c_2 =$9.20

Now the slope can be evaluated mathematically as

           s =  \frac{c_2 -c_1 }{w_2 -w_1 }

substituting values

            s =  \frac{9.20 -4.50 }{30 -3.5 }

           s = $0.1774 / pounds

Should the line of best-fit travel through the origin of the graph . Explain your reasoning
igomit [66]
No because if it does then you had no human error and based on what your graphing it is very unlikely that when you have zero at your x axis you will also reasonably be at zero on your y axis! Hope this helps you
