Answer:

h(6) = 13

Step-by-step explanation:

Functions! One of my favorites to answer :)

h(x) = 2x + 1

So, now we plug in h(6). Remember that when we replace the x with the number, we replace it in the right side of the equation as well:

h(6) = 2(6) + 1

Now we multiply 2 * 6:

h(6) = 12 + 1

Now 12 + 1:

h(6) = 13, final answer.

Hope this helps :D

Answer: 13

Step-by-step explanation:

The value of function at f(-1) = -13,

f(0) = -8 and f(2) = 10.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Both linear equations with one variable and those with two variables exist.

Given equations,

f(x) = 9x - 4 where x < 0

f(x) = 9x - 8  where x ≥ 0

to find f(-1),

substitute value in equation f(x) = 9x - 4 where x < 0

f(x) = 9x - 4

f(-1) = 9(-1) - 4

f(-1) = -13

now f(0) and f(2),  substitute in equation f(x) = 9x - 8  where x ≥ 0

f(x) = 9x - 8

f(0) = 9(0) - 8

f(0) = -8

f(2) = 9(2) - 8

f(2) = 10

Hence  f(-1) = -13,

f(0) = -8 and f(2) = 10.

Answer:

The task is to calculate the total amount spent by Mr. Spendalot. To do this, you need to calculate the amount of inventory purchased, apply the discount, calculate the sales tax, and add the tip. Here's one way to do it:

Calculate the amount of inventory purchased: 31% of $1,000,000 is 31/100 * $1,000,000 = $310,000

Determine the discount: Based on the purchase amount of $310,000, Mr. Spendalot qualifies for a discount of 10%. So, the discount is $310,000 * 10% = $31,000.

Calculate the sales tax: 8.5% of the purchase amount after discount is 8.5/100 * ($310,000 - $31,000) = $2,067.50

Add the tip: 15% of the purchase amount after discount and sales tax is 15/100 * ($310,000 - $31,000 + $2,067.50) = $52,101.13

Calculate the total: The total amount spent by Mr. Spendalot is ($310,000 - $31,000 + $2,067.50 + $52,101.13) = $393,168.63.

So, the total amount spent by Mr. Spendalot is $393,168.63.

Step-by-step explanation:

Determine the amount of purchase before discount: Mr. Spendalot bought 31% of Mr. Shine's inventory, which is $1,000,000. Therefore, his purchase before discount is 31% of $1,000,000, or $310,000.

Calculate the discount: Based on the information in the discount table, Mr. Spendalot's purchase qualifies for a 40% discount. Therefore, the discount amount is $310,000 * 40%, or $124,000.

Determine the amount of purchase after discount: After getting the 40% discount, Mr. Spendalot's purchase is $310,000 - $124,000, or $186,000.

Calculate the sales tax: Mr. Shine charged an 8.5% sales tax on Mr. Spendalot's purchase after discount. Therefore, the sales tax amount is $186,000 * 8.5%, or $15,791.

Determine the tip: Mr. Spendalot gave Mr. Shine and his staff a 15% tip on his purchase after discount and sales tax. Therefore, the tip amount is $186,000 + $15,791 * 15%, or $31,328.

Calculate the total cost: Adding up the purchase after discount, sales tax, and tip, we get the total cost of $186,000 + $15,791 + $31,328, or $233,119.

Conclusion: Mr. Spendalot's total purchase cost is $233,119.

The task requires you to calculate the total amount spent by Mr. Spendalot at Mr. Shine's store Ice Box. Mr. Shine has an inventory worth $1,000,000 which he marks up by 150%. Mr. Spendalot bought 31% of this inventory, and was given a discount based on the amount he spent:

Spend 250k+ and get 20% off

Spend 500k+ and get 30% off

Spend 750k+ and get 40% off

Spend 1 million+ and get 50% off

After the discount, Mr. Spendalot was charged 8.5% sales tax. He also left a 15% tip for Mr. Shine and his staff. Your goal is to calculate the total amount spent by Mr. Spendalot.

The value of the sum of the series is are 315, 1600 and 104

In an arithmetic series, the sum of the first "n" terms (Sn) is given by the formula:

Sn = n/2 * (a1 + an)

Where "a1" is the first term and "an" is the nth term.

For the first series, we have

In this series, a1= 3 , an= 42 , n= 14

Plugging these values into the formula, we get:

Sn = 14/2 * (3 + 42)

Sn = 315

For the second series, we have

In this series, a1= −20 , n= 25 , an= 148

Plugging these values into the formula, we get:

Sn = 25/2 * (-20 + 148)

Sn = 1600

For the third series, we have

In this series, a1=5 , d=1/2 , n=13

So, we have

an = a + (n - 1)d = 5 + 12 * 1/2 = 11

Plugging these values into the formula, we get:

Sn = 13/2 * (5 + 11)

The value of quantity demanded at unit price Gh¢10 is 450 units. b. The price to sell 200 units is Gh¢60. c. The price for 0 demand is Gh¢100. d. The quantity demanded at zero price is 500 units.

The link between the quantity demanded for a commodity (the dependent variable) and its price is represented by the demand function (independent variable).

a) At the price of Gh¢10 , then

Qd= 500 - 5P

Qd= 500 -5(10)

Qd= 500-50 = 450 units

The value of quantity demanded at unit price Gh¢10 is 450 units.

b) If there are 200 units,then

Qd= 500- 5P

200 = 500-5P

5P = 500-200

P= 300/5

P= Gh¢60

The price to sell 200 units is Gh¢60

c) if demand is zero, it mens Qd= 0

Qd= 500- 5P

0= 500-5P

5P= 500

P= Gh¢100

The price for 0 demand is Gh¢100.

d) If P= 0, then

Qd= 500-5P

Qd= 500-5(0)

Qd= 500 units

The quantity demanded at zero price is 500 units.

Hence, the value of quantity demanded at unit price Gh¢10 is 450 units. b. The price to sell 200 units is Gh¢60. c. The price for 0 demand is Gh¢100. d. The quantity demanded at zero price is 500 units.

well, we can simply find how much for each tulip in each store.

store left has them for £9.8 for 4, that means 9.8 / 4 = 2.45, so £2.45 for each tulip.

store right had them for £4.2 each, but they went down by 1/3, so hmm a whole is 3/3 so if we take away 1/3 from 3/3, 3/3 - 1/3 = 2/3, so the new discounted price is really 2/3 of £4.2, that's (2/3) * 4.2 = 2.8, so £2.8 each.

so store left has them cheaper, doesn't matter at a dozen or less or more.

how much is it at store left for 12?  12 * 2.45 = 29.4, or £29.4.

Answer:

A and D

Step-by-step explanation:

Given the function:

[tex]\displaystyle{f(x)=\sqrt{5-x^2}}[/tex]

In order to find the first-order derivative of square root function, we have to convert the form of surd to exponent form. Therefore:

[tex]\displaystyle{f(x)=\left(5-x^2\right)^{\frac{1}{2}}}[/tex]

Since the exponent is a constant and that the base is an expression with variable, we can apply the chain rule (power rule variation):

[tex]\displaystyle{f(x) = u^n \to f'(x) = nu^{n-1} \cdot \dfrac{du}{dx}}[/tex]

Therefore:

[tex]\displaystyle{f'(x)=\dfrac{1}{2}\left(5-x^2\right)^{\frac{1}{2}-1} \cdot \dfrac{d}{dx}\left(5-x^2\right)}\\\\\displaystyle{f'(x)=\dfrac{1}{2}\left(5-x^2\right)^{\frac{1}{2}-\frac{2}{2}} \cdot \dfrac{d}{dx}\left(5-x^2\right)}\\\\\displaystyle{f'(x)=\dfrac{1}{2}\left(5-x^2\right)^{-\frac{1}{2}} \cdot \dfrac{d}{dx}\left(5-x^2\right)}[/tex]

Deriving 5 - x²:

[tex]\displaystyle{\dfrac{d}{dx}\left(5-x^2\right) = 0 - 2x^{2-1}}\\\\\displaystyle{\dfrac{d}{dx}\left(5-x^2\right) = -2x}[/tex]

Thus:

[tex]\displaystyle{f'(x)=\dfrac{1}{2}\left(5-x^2\right)^{-\frac{1}{2}} \cdot (-2x)}\\\\\displaystyle{f'(x)=\dfrac{1}{2}(-2x)\left(5-x^2\right)^{-\frac{1}{2}} }\\\\\displaystyle{f'(x)=-x\left(5-x^2\right)^{-\frac{1}{2}} }[/tex]

You can also convert to the square root form of:

[tex]\displaystyle{f'(x)= \dfrac{-x}{\sqrt{5-x^2}}}[/tex]

Therefore, A and D are correct.

On solving the provided question, we can say that by percentage 9.6  gallons of a 34% sugar solution do we need to mix with 96 gallons of a 10% sugar solution

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.
