Answer:

$3.42 spent on folders, She will receive $6.58 back in change

Step-by-step explanation:

$0.57 times 6 = $3.42 spent on the folders. $10-$3.42=$6.58 she will receive back.

Part 1: She spent $3.42 on the folders.

This is calculated by multiplying 6 folders by $0.57 for each folder

($0.57 x 6 = $3.42).

Part 2: She will receive $6.58 in change. This is calculated by subtracting the amount spent on the folders from the amount of money Gi Gi had to begin with ($10 - $3.42 = $6.58).

Answer:

2 and - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the gradient and c the y- intercept )

f(x) = 2x - 1 ← is in slope- intercept form

with gradient m = 2

• Parallel lines have equal gradients , then

the gradient of a parallel line is also 2

given a line with gradient m then the gradient of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]

The logarithm statement log_b x / log_b y = log_b x/y is a false statement as log_b x / log_b y = log_b x - log_b y.

We are given the logarithm as:

log_b x / log_b y = log_b x/y

We need to tell if it is true of not.

We get that, it is false statement.

We know that log a / log b = log a - log b

So, log_b x / log_b y = log_b x - log_b y

So, it is not equal to log_b x / y

Therefore, we get that, the logarithm statement log_b x / log_b y = log_b x/y is a false statement as log_b x / log_b y = log_b x - log_b y.

The factors are (x + 4), (x + 5) & (x - 4) and the solution is x = -4,  = -5 and x = 4 and the value of the maximum profit is 680

The given parameters are

f(x) = x^3 + 5x^2 - 16x - 80

x = -4 is a root

To set up the synthetic division, we start by writing out the coefficient of each term

So, we have

-4 |  1    5    -16    -80

Bring down the first coefficient

-4 |  1    5    -16    -80

      1

Multiply by -4

So, we have

-4 |  1    5    -16    -80

           (-4)

      1

Add

-4 |  1    5    -16    -80

           (-4)

      1     1

Multiply by -4

So, we have

-4 |  1    5    -16    -80

           (-4)  (-4)

      1     1

Add

So, we have

-4 |  1    5    -16    -80

           (-4)  (-4)

      1     1     -20

Multiply by -4

-4 |  1    5    -16    -80

           (-4)  (-4)    80

      1     1     -20

Add

So, we have

Multiply by -4

-4 |  1    5    -16    -80

           (-4)  (-4)    80

      1     1     -20    0

This means that,

Quotient = x^2 + x - 20

Remainder = 0

Expand x^2 + x - 20

x^2 + x - 20 =x^2 + 5x - 4x - 20

Factorize

x^2 + x - 20 = (x + 5)(x - 4)

Recall that the initial root is

x = -4

Rewrite as

x + 4 = 0

So, we have the complete factor to be

f(x) = (x + 4)(x + 5)(x - 4)

Set to 0

(x + 4)(x + 5)(x - 4) = 0

Solve for x

x = -4,  = -5 and x = 4

Hence, the factors are (x + 4), (x + 5) & (x - 4) and the solution is x = -4,  = -5 and x = 4

The equation of the profit function is given as

P(x) = 230 + 30x - 0.5x^2

Differentiate the function

So, we have

P'(x) = 0 + 30 - x

Evaluate the like terms in the function

So, we have

P'(x) = 30 - x

Set the function to 0

So, we have

30 - x = 0

Evaluate

x = 30

Substitute x = 30 in the equation P(x) = 230 + 30x - 0.5x^2

So, we have

P(30) = 230 + 30 x 30 - 0.5 x 30^2

Evaluate

P(30) = 680

Rewrite as

Pmax = 680

Hence, the value of the maximum profit is 680

The radical expression 3√0.008 y^3 x^6 can be simplified into 0.2 y x^2.

Radical expression is an expression containing a √ symbol. It shows the nth root of a number or variable. This number or variable inside a radical expression is the nth power of another number. Radical expression can also be expressed in exponent notation such that the nth root of x is equal to x raised to 1 over n.

n √x = x^1/n

Expressing 3√0.008 y^3 x^6 into exponent notation:

3√0.008 y^3 x^6 = (0.008 y^3 x^6)^1/3

Applying the distributive property of exponents,

(0.008 y^3 x^6)^1/3 = 0.008^1/3 (y^3)^1/3 (x^6)^1/3

Using the Power Rule for Exponents which states that to raise a number with an exponent to a power, multiply the exponent times the power:

(a^m)^n = a^(m*n).

0.008^1/3 (y^3)^1/3 (x^6)^1/3 = 0.008^1/3 y x^2

Simplifying the constant,

The total amount that Amy will spend is $17.98

Amy goes out to eat at El Parral. She orders a Burritos Deluxe dinner for $8.75, fried ice cream for $4, and a Coke for $2.

Amy's gross total is $8.75 + $4 + $ 2  = $14.75

Now, sales tax of 6 percent

Her net bill is $14.75 + 6% of $14.75

$ 14.75 + 0.885

The simple way to solve such an expression; −(−8q−8.7) as given in the task content is by the distributive property which yields; 8q + 8.7.

It follows from the task content that the expression which is to be simplified, or perhaps written in a different form is; −(−8q−8.7).

Therefore, it follows from the distributive property that we have;

-(-8q) -(-8.7)

Also, since the product of two negative signs yields a positive sign.

Hence, we have; 8q + 8.7 as the equivalent of the expression given.

x = 0           x-1 = 0             x + 4 = 0
