The perimeter of a square is the sum of its sides and they are all equal, so to obtain the length of each of them we divide the perimeter of the first fence between 4:

\(\text{P1}= \dfrac{\text{64 feet}}{\text{4 sides}}\)

\(\text{P1}= 16 \ \text{feet}\)

Then, the length of each side of the second fence will increase 2 feet at each end, as shown in the figure. We have then that the perimeter of the second fence is:

\(\text{P2 = 20 feet} \times \text{4 sides}\)

\(\text{P2 = 80 feet}\)

The sum of the perimeters of both fences is:

\(\text{PT = P1 + P2}\)

\(\text{PT = 64 feet + 80 feet}\)

\(\text{PT = 144 feet}\)

Total cost = $1.26 x 144 feet

Total cost = $181.44

The total cost of the fences was $181.44

The Linear terms -0.75(-4f + 12) and (5f + 9) - (2f + 18) are actually an equivalent expressions.

Equivalent algebraic expressions are ones that, despite their apparent differences, actually have the same value. As a result of their similarity, they will produce the same outcomes regardless of the values we choose to use as their variables.

If  -0.75 ( -4f + 12 ) and ( 5f + 9 ) - ( 2f + 18 ) are equivalent expressions then

-0.75(-4f + 12) = (5f + 9) - (2f + 18)

3f − 9 = (5f + 9) - (2f + 18)

3f − 9 = 5f + 9 -2f - 18

3f − 9 = 5f - 2f + 9  - 18

3f − 9 = 3f − 9

Thus, The Linear terms -0.75(-4f + 12) and (5f + 9) - (2f + 18) are actually an equivalent expressions.

Answer: 13 7/8

Step-by-step explanation:

11 + 1/8 + 3/4 + 2 = 13 7/8

Step-by-step explanation:

it seems you solved the tricky part yourself already.

just to be sure, let's do the first derivative here again.

the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...

f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =

= 3t⁴ + 18t³ + 24t² + 18t + 21

f'(t) = 12t³ + 54t² + 48t + 18

and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).

we simply put the input number (2) at every place of the input variable (t).

so,

f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =

= 426

Answer:

= (-7/3) ×(6) + (-3)^2

= -7×2 + 9

= -14+ 9

[ it comes (+9) because (-3)×(-3) = +9 ]

-5 is the answer

First let's re write the equation -5x+6y=14 as

5x-6y=-14 by multiplying through by negative(-)

next I to find the intercepts. To find the intercept on line y we make x=0 therefore

5(0)-6y=-14

-6y=-14

y=2.33 by dividing both sides by -6

do the same for the ( x )

x=-2.8

Therefore, **x < 7** is the inequality that may be utilized to find x

A mathematical statement known as an inequality compares two expressions using an inequality sign, such as (less than), > (greater than), or (less than or equal to).

For instance, the inequality x + 2 5 signifies that "x + 2 is less than 5".

Let x represent how many days the client paid for pet sitting.

$15 per day plus a $20 fixed service fee equals the total cost of pet sitting.

We are aware that the customer's purchase was under $125. Consequently, we can write:

20 + 15x < 125

Putting this disparity simply:

15x < 105

x < 7

The initial value of the investment in the given function is 1500.

Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter.,

\(A = P(1+ \dfrac{r}{n})^{nt}\)

where A is the final amount

P is the principal amount

r is the rate of interest

n is the number of times interest is charged in a year

Answer:

48

Step-by-step explanation:

16×3=48

therefore the answer is forty eight

Answer:

It would take 10 years

Step-by-step explanation:

The function g(x) can be expressed as g(x) = a(x - h) + k, where a is the coefficient of x (which is 1 for f(x) = x^2), h is the horizontal shift, and k is the vertical shift.

To translate a function 6 units left, we need to shift it horizontally by -6 units. So, h = -6.

Since the function g(x) is a translation of f(x), a and k will have the same values as in f(x). In this case, a = 1 and k = 0.

Therefore, the function g(x) that represents the translation 6 units left of f(x) is:

g(x) = a(x - h) + k

= 1(x - (-6)) + 0

= 1(x + 6) + 0

= x + 6

the answer is: g(x) = x + 6

The calculated bill for a person who uses 600kWh in a month is $80

From the question, we have the following parameters that can be used in our computation:

b(x) = 0.10x, x ≤ 200

b(x) = 0.15(x - 200) + 20, x > 200

For a person that uses 600kWh per month, we make use of the function

b(x) = 0.15(x - 200) + 20

This is because it is valid for x > 200

Substitute the known values in the above equation, so, we have the following representation

b(600) = 0.15(600 - 200) + 20

Evaluate

b(600) = 80

Hence, the bill for a person who uses 600kWh in a month is $80

A) \(\frac{8}{17}\)

Step-by-step explanation:

\(\displaystyle \cos\theta=\frac{\text{Adjacent}}{\text{Hypotenuse}}=\frac{8}{17}\)

Answer: OPTION A= 8/17

The ratio for COS A for the given triangle is '8/17 '

Step-by-step explanation:

To find the cosine (cos) ratio for the acute angle A, we need to use a formula i.e., C AH which means 'Cosine is Adjacent over Hypotenuse'.

Mathematically,

                              Cos(A) = Adjacent / Hypotenuse

According to the question, the adjacent side is 8 and the hypotenuse is 17. By putting these values in the above equation the ratio becomes,

                               Cos(A) = 8/17

y-4/x+3 = -3

y-4 = -3(x+3)

y-4=-3x-9

y+3x +9-4=

y+3x+5=0

Answer:

y = -3x - 5

Step-by-step explanation:

-3, 4 and 1, -8

1 - -3 = 4

-8 - 4 = -12

\(\frac{-12}{4}\) = \(\frac{-3}{1}\) = -3

gradient/slope = -3

now substituting in the point -3, 4 to find the y intercept:

4= -3 x -3 + c

4 = 9 + c

-5 = c

y intercept = -5

equation is y = -3x - 5

The number of pairs that should be sold to earn an after-tax profit of GH¢12,000 is approximately 25769, which is closest to option B, 30000 units.

What is profit?

Gain is the best definition of profit, particularly when it is attained by raising the price of goods so that customer spending exceeds producer expenses and a sizable return on investment is left. Profit is the amount of money that remains after costs and expenditures have been paid.

First, let's calculate the total revenue from selling 25,000 pairs of shoes:

Total revenue = selling price per unit * number of units sold

Total revenue = GH¢40 * 25,000

Total revenue = GH¢1,000,000

Next, let's calculate the total cost of producing and selling 25,000 pairs of shoes:

Total cost = (purchase cost per unit + fixed cost per unit) * number of units sold

Total cost = (GH¢25 + GH¢2 + (GH¢100000 + GH¢40000 + GH¢100000)/25000) * 25000

Total cost = (GH¢25 + GH¢2 + GH¢16) * 25000

Total cost = GH¢43 * 25000

Total cost = GH¢1,075,000

Now, we need to calculate the before-tax profit:

Before-tax profit = Total revenue - Total cost

Before-tax profit = GH¢1,000,000 - GH¢1,075,000

Before-tax profit = -GH¢75,000

Since the before-tax profit is negative, the company is making a loss. To make an after-tax profit of GH¢12,000, we need to add this amount to the before-tax profit and then adjust for the tax rate:

Before-tax profit + After-tax profit = Target profit

-GH¢75,000 + GH¢12,000 = Target profit

Target profit = -GH¢63,000

Adjusted Target profit = Target profit / (1 - tax rate)

Adjusted Target profit = -GH¢63,000 / (1 - 0.4)

Adjusted Target profit = -GH¢105,000

To make an adjusted target profit of GH¢105,000, we can use the following formula to calculate the number of units that need to be sold:

Number of units sold = (Fixed cost + Target profit) / (Selling price per unit - Purchase cost per unit - Selling commission per unit)

Number of units sold = (GH¢100,000 + GH¢40000 + GH¢100,000 - GH¢105,000) / (GH¢40 - GH¢25 - GH¢2)

Number of units sold = GH¢335,000 / GH¢13

Number of units sold ≈ 25769.23

Therefore, the number of pairs that should be sold to earn an after-tax profit of GH¢12,000 is approximately 25769, which is closest to option B, 30000 units.
