You buy a laptop that costs £899, including VAT at 20%. How much of the purchase price is VAT?

Answer:

calculate the difference height (P) is -6 and (t) is 2.85

Δy divided by Δx = rate of change

3-9 = -6

6.23-3.41 = 2.85

then divide

2.85 / -6 = .475

Your answer will be - .475

Step-by-step explanation:

Using the table, the average rate of change from 3 to 9 seconds  is of -0.475 feet per second.

The average rate of change of a function P(x) over an interval [a,b] is given by:

[tex]A = \frac{P(b) - P(a)}{b - a}[/tex]

In this problem, we want the rate from 3 to 9 seconds, hence [tex]a = 3, b = 9[/tex].

[tex]A = \frac{3.41 - 6.26}{9 - 3} = -0.475[/tex]

Considering the units, the average rate of change from 3 to 9 seconds is of -0.475 feet per second.

ANSWER

The domain is an empty set

EXPLANATION

The given functions are:

[tex]f(x) = \sqrt{x - 3} [/tex]

and

[tex]g(x) =1 - {x}^{2}[/tex]

[tex](f \circ \: g)(x) = f(g(x))[/tex]

[tex](f \circ \: g)(x) = f(1 - {x}^{2} )[/tex]

[tex](f \circ \: g)(x) = \sqrt{(1 - {x}^{2} ) - 3} [/tex]

[tex](f \circ \: g)(x) = \sqrt{ - {x}^{2} - 2} [/tex]

This function is defined if and only if

[tex] - {x}^{2} - 2 \geqslant 0[/tex]

[tex] {x}^{2} + 2 \leqslant 0[/tex]

There is no real values that satisfies this inequality, because

[tex] {x}^{2} + 2[/tex]

is always positive.

The domain of this composite function is a null set.

Answer:

The domain of f, and thus the range of g, is restricted to values greater than or equal to 3.

If 1 minus x squared is greater than or equal to 3, then x squared must be less than –2.

Since x squared cannot be less than a negative number, the function is undefined for all values of x.

Answer:

One effect of higher food prices in a given country is higher consumer price index (CPI) inflation.However, higher food prices affect people in different economies differently.

The impact of rapidly rising food prices on CPI inflation is substantially larger in emerging market economies than advanced economies

This effect tends to be much greater for countries that are 1) large net importers of food, and 2) where households spend a greater percentage of their income on food (meaning that they have a much larger weighting of food in their CPI basket).

In short, higher food prices don't hurt everyone equally. Poorer, developing economies feel it much worse.

Answer:

Here's some you can use below!:

Step-by-step explanation:

Oil is used in the processing of many food products. In additional, oil is used in the transportation of food. As a result, with oil price increases, the price of food increases as well.

The world population continues to grow, and with that comes increased demand of various food products. As a result, this rising demand directly leads to higher prices.

The increases in food prices have already taken effect and are not likely to improve in the near future. As of February 2011, the price of wheat has increased 83% and the price of corn has doubled since one year earlier. As feed becomes more expensive, the cost of beef products is expected to increase by almost 40%, leading to much higher prices for any meat eaters out there. With unemployment remaining at very high levels, these prices will serve to further put a dent in our wallets.

The situation is even more dire in poorer countries as many of their citizens spend about 80% of their income on basic food products. As a result, food price increases can be devastating to people in these countries, with an additional 44 million people already having been pushed into poverty. The food crisis has inspired riots in countries such as Egypt, Haiti, Tunisia, and Algeria.

Final answer:

To find the amounts of sales that will meet Liz's goal, we can set up an inequality using her salary and commission. Liz needs to earn at least $2,700 this month, and with her salary and commission, we can create the inequality $2,500 + 0.06x ≥ $2,700. Solving this inequality gives us x ≥ $3,333.33. Therefore, the amounts of sales that will meet Liz's goal are any values of x that are greater than or equal to $3,333.33.

Explanation:

To find the amounts of sales that will meet Liz's goal of earning at least $2,700 this month, we can set up an inequality. Let's represent the amount of sales as 'x'.

Liz's salary is $2,500 per month, and her commission is 6% of her sales. So her total earnings for the month can be calculated as:

Total Earnings = Salary + Commission

Total Earnings = $2,500 + 0.06x (since the commission is 6% of sales)

We want Liz to earn at least $2,700, so we can set up the following inequality:

$2,500 + 0.06x ≥ $2,700

To solve this inequality, we can subtract $2,500 from both sides:

0.06x ≥ $2,700 - $2,500

0.06x ≥ $200

Finally, we divide both sides by 0.06 to isolate 'x', the amount of sales:

x ≥ $200 ÷ 0.06

x ≥ $3,333.33

Therefore, the amounts of sales that will meet Liz's goal are any values of 'x' that are greater than or equal to $3,333.33.

Answer:

The answer is 7*7*7*7*7

Step-by-step explanation:

The correct way to write 7^5 as a multiplication expression is by writing it as 7 multiplied by itself 5 times, which is 7 x 7 x 7 x 7 x 7.

The question asks how to write 7^5 as a multiplication expression. To correctly express 7^5, we represent it as 7 being multiplied by itself 5 times. So, the correct way to write 7^5 as a multiplication expression is 7 \u00d7 7 \u00d7 7 \u00d7 7 \u00d7 7. This clearly demonstrates the concept of an exponent, where the base (7) is multiplied by itself a certain number of times (5 times in this case), which is fundamentally different from just multiplying 7 by 5.

They believed in a system owned and run by the individual

Step-by-step explanation:

In the early 1900's the majority of the Americans rejected the Marxist ideology, and they saw it as usurpation of their country and its foundations. The majority of the Americans favored the capitalism, and they saw their country as the country of opportunities where everyone can achieve everything if the person is smart enough and works hard enough. The Marxism suggested the total opposite of it, that everyone should be equal, have the same earnings, there's no prosper on a career level, so for the Americans was not attractive, and we can comfortably say that they made the right choice considering what happened in the countries that adopted this ideology.

Second point (-5/2, -7/2)

First point (3/2, 17/2)

Step-by-step explanation:

We have two equations, and we want to know at wich poin are equal. Hence, we have a system of equations and the solution is nothing more that the point (x,y) where those functions intercepts.

4x2+ 7x -11=y

3x+4=y

Lets use substitute method

4x2+7x-11=3x+4

This can be re arrange as the following eq:

4x2+4x-15=0

A quadratic equation, its solution can be obtained using the below eq.

[tex]x=\frac{-b+/- \sqrt{x^{2}-4ac } }{2a}[/tex]

where a=4, b=4, c=-15.

Remember, the quadratic equation as a +/- sign, meaning that you will obtain one answer using the + operator and other using the - operator.

By doing the above, we have x=-5/2 and x=3/2

By using x=3/2 in equation of line (3x+4=y)  we have y=17/2

First point (3/2, 17/2)

By using x=-5/2 in equation of line (3x+4=y) we have y= -7/2

Second point (-5/2, -7/2)

Those points are the ones where the line and the parabola intercept.

Answer
5,000

Explanation
1. Examine the number next to the thousands value (hundreds place)

2. Should that number be greater than 5, round the thousands value up one.

To round 4708.06 to the nearest thousand, we look at the hundreds place value which is '7'. Since it's higher than 5, we round up the thousands of places and the number becomes 5000.

The process of rounding involves deciding which multiple of a certain number is closest to the number you're trying to round. If to round the number 4708.06 to the nearest thousand, we look at the hundreds place. In our case, it's '7', a digit that is 5 or higher.

Thus, we increase the digit at the thousands place by '1' and change all the subsequent digits to '0'. Therefore, 4708.06 rounds to 5000 when rounded to the nearest thousand.

Answer:

3 more trays

Step-by-step explanation:

At 35 cookies per tray, x trays is sufficient for an output of 840 cookies.  Dividing 840 cookies by 35 cookies/tray, we get  24  trays.

But Ms. Sharp already has 21 trays.

Thus, she needs 3 more to be able to bake 840 cookies.

Ms Sharp will need to bake 3 more trays of cookies to meet the requirement of 840 cookies.

To determine how many more trays of cookies Ms. Sharp needs to bake, we first calculate the total number of cookies she has already baked. She baked 21 trays with 35 cookies on each tray:

[tex]\[21 \text{ trays} \times 35 \text{ cookies per tray} = 735 \text{ cookies}\][/tex]

Ms. Sharp needs a total of 840 cookies. Therefore, we need to find out how many more cookies are required:

[tex]\[840 \text{ cookies} - 735 \text{ cookies} = 105 \text{ cookies}\][/tex]

Each tray contains 35 cookies, so we need to determine how many more trays are required to bake 105 cookies:

[tex]\[\frac{105 \text{ cookies}}{35 \text{ cookies per tray}} = 3 \text{ trays}\][/tex]

Therefore, Ms. Sharp will need to bake an additional:

[tex]\[\boxed{3}\][/tex] trays of cookies.
