Answer:

f(x) is 579.

Step-by-step explanation:

The equation y=9x^6+x^4-2x^2-5 represents a function where y depends on the value of x. To find the f(x) of this function, we simply replace y with f(x), which gives us:

f(x) = 9x^6 + x^4 - 2x^2 - 5

This means that if you plug in a specific value of x, the function will output a corresponding value of f(x). For example, if you plug in x=2, you would get:

f(2) = 9(2)^6 + (2)^4 - 2(2)^2 - 5

f(2) = 9(64) + 16 - 8 - 5

f(2) = 576 + 3

f(2) = 579

So when x is 2, f(x) is 579.

These two expressions can be used to represent the total amount you will have to pay, taking into account the cost of a cookie and the sales tax of 5.5%.

To calculate the total amount you will have to pay, considering the cost of a cookie (represented by "c") and the sales tax of 5.5%, you can use the following expressions:

Expression for the sales tax amount:

The sales tax amount can be calculated by multiplying the cost of the cookie (c) by the sales tax rate of 5.5% (or 0.055). The expression would be:

Sales Tax = c × 0.055

Expression for the total amount to be paid:

To calculate the total amount you will have to pay, including the cost of the cookie and the sales tax, you need to add the cost of the cookie to the sales tax amount. The expression would be:

Total Amount = c + (c × 0.055)

Therefore, these two expressions can be used to represent the total amount you will have to pay, taking into account the cost of a cookie and the sales tax of 5.5%.

The two expressions representing the total amount to pay after sales tax of [tex]5.5\%[/tex]:

[tex]\[ \text{Sales tax amount} = 0.055c \][/tex]

[tex]\[ \text{Total amount with tax} = 1.055c \][/tex]

To represent the total amount you will have to pay when buying a cookie, including the sales tax of [tex]5.5\%[/tex], we can start with the cost of the cookie, represented by the variable [tex]\(c\)[/tex]. The two expressions required are as follows:

1. Expression for the total amount with tax added:

The first expression represents the total amount you need to pay, which includes the cost of the cookie plus the sales tax. The sales tax of [tex]5.5\%[/tex] can be calculated by multiplying the cost of the cookie [tex](\(c\))[/tex] by [tex]0.055[/tex] (since [tex]5.5\%[/tex] is equivalent to [tex]0.055[/tex] as a decimal). Therefore, the expression becomes:

[tex]\[ \text{Total amount with tax} = c + 0.055c \][/tex]

Simplifying this expression, we can combine the two terms involving [tex]\(c\)[/tex]:

[tex]\[ \text{Total amount with tax} = 1.055c \][/tex]

2. Expression for the sales tax amount:

The second expression represents only the sales tax amount that needs to be added to the cost of the cookie. It can be calculated by multiplying the cost of the cookie [tex](\(c\))[/tex] by [tex]0.055[/tex]. Thus, the expression is:

[tex]\[ \text{Sales tax amount} = 0.055c \][/tex]

To find the first derivative of the function [tex]f(x) = (7x + 3)(4 - 3x)[/tex], we can apply the product rule of differentiation.

According to the product rule, if we have two functions, u(x) and v(x), the derivative of their product is given by:

In our case, let's designate u(x) = 7x + 3 and v(x) = 4 - 3x. We can now compute the derivatives of u(x) and v(x):

u'(x) = 7 (the derivative of 7x is 7)

v'(x) = -3 (the derivative of -3x is -3)

Now, we can apply the product rule:

[tex]f'(x) = (7x + 3)(-3) + (7)(4 - 3x)[/tex]

Randy made an error while dividing (2x⁴ - 3x³ - 3x² + 7x - 3) by (x² - 2x + 1). He mistakenly subtracted intermediate results from zero instead of the original polynomial, leading to an incorrect division.

Randy made an error in his division of the polynomial (2x⁴ - 3x³ - 3x² + 7x - 3) by (x² - 2x + 1). Let's go through the division process step by step to identify the mistake:

Randy correctly started by dividing 2x⁴ by x², which gives him 2x² as the first term of the quotient.

He then multiplied (x² - 2x + 1) by 2x², which resulted in 2x⁴ - 4x³ + 2x². So far, so good.

Randy should have subtracted this result from the original polynomial (2x⁴ - 3x³ - 3x² + 7x - 3), but he mistakenly subtracted it from 0. The correct step should have been to subtract 2x⁴ - 4x³ + 2x² from (2x⁴ - 3x³ - 3x² + 7x - 3).

Here's the corrected division:

(2x⁴ - 3x³ - 3x² + 7x - 3) - (2x⁴ - 4x³ + 2x²) = -3x³ - 5x² + 7x - 3

Now, Randy should have continued the division by bringing down the next term, which is -3x², and repeated the process. However, he incorrectly moved to the next step without subtracting -3x³ - 5x² + 7x - 3 from (x² - 2x + 1).

So, Randy's error is that he failed to properly subtract the intermediate result from the original polynomial, causing the division process to go awry.

(a)

Bank A: Omar would pay a flat fee of $40 for the checking account and debit card, regardless of the number of transactions he makes.

Bank B: Omar would pay $20 for the checking account and debit card, plus $0.40 for each transaction. For 40 transactions, he would pay:

$20 + (40 × $0.40) = $20 + $16 = $36

Each year, your bank account would accumulate $30 in interest.

A bank account is a financial account provided by a bank or financial institution that allows individuals or businesses to deposit money, make withdrawals, and perform various financial transactions. Bank accounts offer a secure and convenient way to manage and store your money.

To calculate the amount of money that would accumulate in your bank account each year from a $600 tax refund invested at 5% simple interest, we can use the formula:

Interest = Principal * Rate

where:

Principal = $600 (initial investment)

Rate = 5% (0.05 in decimal form)

Interest = $600 * 0.05

Interest = $30

Therefore, each year, your bank account would accumulate $30 in interest.
