Expert Solution & Answer
Check Mark
To determine

To calculate: The value of expression y=4x2 for x equal to 3.

Answer to Problem 1CP

Solution:

The value of the given expression is 49_.

Explanation of Solution

Given Information:

The expression is y=4x2.

Formula used:

Use the property of negative exponent,

xn=1xn

Calculation:

The exponent expression is, y=4x2

Substitute 3 for x in the above expression.

y=4x2=4(3)2

Now, from the property of negative exponent.

y=4(13)2=49

Hence, the value of the provided expression for x equal to 3 is 49.

A low resting heart rate can mean a high degree of physical fitness, which is associated with reducedrates of cardiac events like heart attacks. By working out regularly in the gym, the heart becomes moreefficient, pumping the lowest amount of blood one needs when in a relaxed state. Normal resting heartrate for adults ranges from 60 to 100 beats per minute but a well-trained athlete can have a normal restingheart rate as low as 40 beats per minute. Dr. Castillejo wants to know if her gym members have attainedthis average resting heart rate of athletes. Use the R commander output below to address Dr. Castillejo’sconcern . Write a brief report about the analysis by identifying the set of hypotheses to be tested, theappropriate test to use, and implications and recommendations of/from the conclusions.
