Identify the relative maximum value of g(x) for the function shown below g(x)=7/x^2+5
Liula [17]
To find t<span>he relative maximum value of the function we need to find where the function has its first derivative equal to 0.

Its first derivative is -7*(2x)/(x^2+5)^2
</span>7*(2x)/(x^2+5)^2 =0 the numerator needs to be eqaul to 0
2x=0
x=0

g(0) = 7/5

The <span>relative maximum value is at the point (0, 7/5).</span>

g A university administrator obtains a sample of the academic records of past and present scholarship athletes at the university
kupik [55]

Answer:

the chance of obtaining a difference in GPAs between male and female scholarship athletes as large as that observed in the sample if there is no difference in mean GPAs is 0.287

Step-by-step explanation:

When conducting hypothesis tests, the P value tells you the probability of the results happening by random chance.  That's why we usually test against a very low alpha level, usually 1% or 5%.  

Here P = 28%, so there is a 28% chance that if we take a sample of athletes, about 1 out of 4 times there won't be a significant difference in GPA between males and females.

The Smith Family is designing new plans for an in ground pool. Mr. Smith draws a rectangular shape with a length that is 5 feet
kumpel [21]

To solve this problem you must apply the proccedure shown below:

1- The formula for calculate the area of this rectangle is:

A=LH

Where L is the length and H is the heigth.

2. Let's call identify the heigth with the variable x.

3. If the length is 5ft longer than the heigth, you have:

L=x+5

4. Therefore, you can write the following polynomial expression:

A(x)=x(x+5)\\ A(x)=x^{2} +5x

5. If you know the value of the heigth, you can susbstitute it into the polynomial expression shown above and you will obtain the area.

Therefore, the answer is: A(x)=x^{2} +5x
