Well, most books define critical values of a function as x-values where f'(x)=0 or f'(x) is undefined, so they occur there because that's the definition of what a critical value is.

But the reason we define it that way is that when you're looking for local extrema (local mins and/or local maxs), these must occur when f'(x)=0 or f'(x) is undefined.  

If f has a local extremum at a point x=c, then f'(c)=0 or f'(c) is undefined.

Answer:

The answers are x=-37 and x=3

Step-by-step explanation:

The solution set for the equation (7x+3)(2x-6)=0 is {−37,3}. To solve for x, one can use the distributive property to expand the equation and then solve for x. For example, 7x² - 3x - 12x - 18 = 0 can be rearranged to 7x² - 15x - 18 = 0 and then solved using the quadratic formula.

Answer: The formula for continuously compounded interest is given by:

A = P * e^(rt)

Where:

A = the final account balance

P = the initial investment (principal)

r = the annual growth rate as a decimal

t = the number of years the investment is held

In this case, P = 540, r = 0.091 and t = t years.

So, the function showing the value of the account after t years is:

A = 540 * e^(0.091t)

To find the percentage of growth per year (APY), we can use the formula:

APY = (e^r - 1) * 100

Substituting r = 0.091, we find:

APY = (e^0.091 - 1) * 100 = 9.56%

So, the APY is approximately 9.56%, to the nearest hundredth of a percent.

The average daily balance of the credit card for the January 1 - January 31 billing period is $1283.87.

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

The average daily balance can be determined by dividing the total daily balances for January by the number of days in January.

The average daily balance = Total balance / Total number of days in January.

Total balance = (800 x 1 days) + (1000 x10 days) + (1250 x 10 days) + (1650 x 10 days)

Total balance = 800 + 10,000 + 12,500 + 16,500 = 39800

The average daily balance = 39800/31 = $1283.87

Therefore, the average daily balance of the credit card for the January 1 - January 31 billing period is $1283.87.

The required values of the given composite functions follow as:

(a) fog(x) = 4x², (b) gof(x) = 2x², and (c) gog(x) = x⁴.

Composite functions are mathematical functions that are formed by taking the output of one function and using it as the input for another function.

(a) To find fog(x), we need to evaluate g(f(x)).

Since function f(x) = 2x, we have:

g(f(x)) = g(2x) = (2x)² = 4x²

Therefore, fog(x) = 4x².

(b) To find gof(x), we need to evaluate f(g(x)).

Since g(x) = x², we have:

f(g(x)) = f(x²) = 2(x²) = 2x²

Therefore, gof(x) = 2x².

(c) To find gog(x), we need to evaluate g(g(x)).

Since function g(x) = x², we have:

g(g(x)) = g(x²) = (x²)² = x⁴

Answer: To calculate the total, we need to first calculate the discount and then the tip.

First, calculate the discount: $21.50 x 10% = $2.15

Then, subtract the discount from the subtotal: $21.50 - $2.15 = $19.35

Next, calculate the tip: $19.35 x 20% = $3.87

Finally, add the tip to the subtotal after the discount to find the total: $19.35 + $3.87 = $23.22

Therefore, Abdiel's total would be $23.22 if he uses a coupon for 10% off the subtotal and leaves a 20% tip before the discount.

The correct option that can be used to prove that ∠ABC = ∠FDE is option (A). It is done using rules of congruency.

What is meant by congruency?

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

For the construction of the congruent angle, the compass measurement used is the same for both figures.

Now we draw a line through points A and C and another line through points F and E.

We can then say that

AB = FD

BC = DE

CA = EF

These are the sides of the triangles ΔABC and ΔFDE

As all sides are equal, we can say that

ΔABC ≅ ΔFDE by SSS congruency rule.

Now CPCTC rule says that "corresponding parts of congruent triangles are congruent". This means that the corresponding angles and sides of two or more triangles must also be identical in order for them to be considered congruent.

So ∠ABC ≅ ∠FDE by CPCTC as they are corresponding angles.

Therefore the correct congruency rules that can be used to prove that

∠ABC = ∠FDE is option (A).

Answer: 96 m.

Step-by-step explanation: Let's call the length of the rectangular field "L".

We know the perimeter of the field is equal to the sum of all its sides, so:

350 = 2L + 2 * 79

Expanding the right side, we have:

350 = 2L + 158

Subtracting 158 from both sides:

192 = 2L

Dividing both sides by 2:

L = 96 m

So the length of the rectangular field is 96 m.
