Answer:
£ 253,484.16
Step-by-step explanation:
Cost of house for first year = £235,000
Year 1
Depreciation for first year is 4% = 4/100
Depreciation in £ = 235,000 x 4/100 = £9,400
Effective value of house at end of first year
= 235000 - 9400 = £225,600
Year 2
In the second year the house value increased by 6% = 6/100
So total increase in £ at the end of year 2 with an initial value of £225,600 = £225,600 x 6/100 = £13,536
So actual value of house at end of year 2
= £225,600 + £13,536
= £239,136
Year 3
The value increased by 6% for year 3.
Value at beginning of year 3 = £239,136
Increase in value at 6% = £239,136 x 6/100 = £14,348.16
Total Value at end of year 3
= £239,136 + £14,348.16
= £253,484.16
Answer: £253,484.16
Note
Another way of quickly calculating this is noting that 4% depreciation means the new value is (1 - 4%) of initial value = 1 - 4/100 = 0.96
An increase of 6% means the new value will be 1.06 times the initial value
So the value of the house after 4% depreciation for the first year and 6% appreciation for the next 2 years
= 235000 x (0.96)(1.06)(1.06) = 253,484.16

If one student is chosen at random, the probability that the student was a female and got 'A' is 0.38
What is probability?Probability is a synonym for potential. It is a field of mathematics that examines how random events happen. From zero to one, the value is expressed. To forecast the likelihood of events, probability has been introduced in mathematics.
The likelihood that something will occur is essentially what is meant by probability. This is the fundamental theory of probability, which is also used to calculate the probability distribution, and it is from it that you will learn the likelihood of various outcomes in a random experiment.
The total number of outcomes that can occur should be known before calculating the likelihood that a specific event will occur.
Total numbers of students = 53
Total numbers of females = 34
Total numbers of females of A grades = 20
So probability = 20/53
= 0.38

The width of a rectangle is 3 units less than the length. The area of the rectangle is 18 units. What is the length, in units, of the rectangle?
Answer:
w=3units l=6 units
Step-by-step explanation:
The required length and width of the rectangle are 6 and 3 units
Given that,
The width of a rectangle is 3 units less than the length. The area of the rectangle is 18 units.
The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.
Here,
Let the length of the rectangle be l and the width of the rectangle is l -3
Now,
area of the rectangle,
18 = l [l - 3]
18 = l² - 3l
l² - 3l - 18 = 0
l² - 6l + 3l - 18 = 0
(l - 6) + 3 (l - 6) = 0
(l - 6)(l + 3) = 0
l = 6 {negative value of the l can be neglected.}
now,
width = 6 - 3 = 3
Thus, the required length and width of the rectangle are 6 and 3 units.

Adriel buys 20 bottles of grapefruit juice at the corner store for a total cost of $7.80.
If each bottle costs the same amount, how much is 6 bottles of juice?
The cost of 6 bottles of juice is $2.34 if the each bottle costs the same.
According to the question,
We have the following information:
Adriel buys 20 bottles of grapefruit juice at the corner store for a total cost of $7.80.
Cost of 20 bottles of juice = $7.80
Now, from here we can find the cost of 1 bottle of juice by dividing the total cost by the number of bottles purchased.
Cost of 1 bottle of juice = $(7.80/20)
Cost of 1 bottle of juice = $0.39
Now, we can easily find the cost of 6 bottles of juice by multiplying the cost of 1 bottle of juice by 6.
Cost of 6 bottles of juice = $(0.39*6)
Cost of 6 bottles of juice = $2.24
Hence, the cost of 6 bottles of juice is $2.24.

Question 3: Kylie needs to spend at least 5 hours each week practicing the piano. She has already practiced 2 and 3/4 hours this week. She wants to split the remaining practice time evenly between the last 3 days of the week. Write an inequality to determine the minimum number of hours she needs to practice on each of the 3 days.
Using proportions with mixed numbers, the inequality to determine the minimum number of hours she needs to practice on each of the 3 days is: m ≥ 3/4.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication or division.
One example is the mean of a data-set, as the mean is given by the sum of all observations in the data-set divided by the number of values.
For this problem, we have that:
She has already practiced 2.75 hours, as the decimal part is of 3/4 = 0.75, hence 2 and 3/4 = 2 + 0.75 = 2.75.She needs to practice 5 hours.Hence the minimum number of hours that she still needs to practice is:
5 - 2.75 = 2.25 hours.
The amount is split evenly amount the 3 days, hence the lower bound of the inequality is:
2.25/3 = 0.75 = 3/4.
Hence the amount is given by:
m ≥ 3/4.

The linear function m = 50 - 9d represents the amount m (in dollars) of money you have
left after buying d DVDs.
a. Interpret the terms and coefficient in the equation.
b. Find the domain of the function. Is the domain discrete or continuous? Explain.
c. Graph the function using its domain.
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
How can you tell whether a domain is continuous or discrete?A domain's discreteness or continuousness can be determined by examining the function's graph. The domain is continuous if the graph is a line. The domain is discrete if the graph consists of a collection of points.
What is a discrete domain example?Private Domain
The values that will be effective for the function are distinct from one another. The maximum number of children you can have, for instance, has a defined answer. You can have 0 children, 1, 2, 3, etc., but not 2,34.
How can you determine a discrete function's domain?Discrete graphs are those in which no lines connect the points. Start by locating all the x-coordinates in order to determine the domain and range of a discrete graph. The graph's entire set of x-coordinates makes up the domain. The graph's entire range of y-coordinates is considered to be the range.
What does a discrete structure's domain mean?The domain is the collection of all possible inputs for a function. The codomain is the collection of all permitted outputs.
What is an example of discrete structures?Graphs, logical assertions, and combinations are a few examples of discrete structures. Infinite or finite discrete structures are both possible. Contrary to continuous mathematics, which works with structures whose values can span the real numbers or have other non-separable qualities, discrete mathematics deals with discrete objects.

Answer:
Domain: All real numbers
Range: f(x) ≥ 5 or f(x) < 2
Step-by-step explanation:
The given graph is a graph of a piecewise function.
Piecewise functions have multiple pieces of curves/lines where each piece corresponds to its definition over an interval.
When graphing piecewise functions:
An open circle is used where the value is not included in the interval.A closed circle is used where the value is included in the interval.An arrow is used to show that the function continues indefinitely.Domain
The domain of a function is the set of all possible input values (x-values).
From inspection of the graph, the arrows show that the function continues indefinitely in both the positive and negative directions.
The value of x = 1 is not included in the left part of the graph, but it is included in the right part of the graph.
Therefore, the domain of the function is all real values of x:
(-∞, ∞)Range
The range of a function is the set of all possible output values (y-values).
From inspection of the graph, there is an open circle at y = 2 and a closed circle at y = 5. Therefore, there are no y-values in the interval:
2 ≤ y < 5.
Therefore, the range of the function is f(x) < 2 or f(x) ≥ 5:

There is no saddle point (DNE). However, there is local maximum at (1, 1/2) for the given function.
we have function of two variables f(x,y)= 9-2x+4y-x^2-4y^2
we will find the values by partial derivative with respect to x,y,xy
f ₓ= -2 -2x
[tex]f_{y}[/tex] = 4 -8y
to find the saddle point we should first find the critical points so equate
-2 -2x=0 and 4 -8y=0
we get x= 1 and y =1/2 so, critical points are (1,1/2)
to find local maximum or minimum we have to find [tex]f_{xx}[/tex] , [tex]f_{yy}[/tex] and [tex]f_{xy}[/tex]
formula is [tex]f_{xx}[/tex]* [tex]f_{yy}[/tex] - [tex]f_{2xy}[/tex] =0
