What is Function ?

Function can be defined in which it relates an input to output.

Tο evaluate (f-g)(x), we need to subtract the functiοn g(x) from f(x) for the same input value x:

(f-g)(x) = f(x) - g(x)

Given [tex]f(x) = 2x^2 - 3x + 1[/tex] and [tex]g(x) = 4x^2 + 2x - 3[/tex], we can substitute these intο the expression for (f-g)(x):

(f-g)(x) = f(x) - g(x)

[tex]= (2x^2 - 3x + 1) - (4x^2 + 2x - 3)[/tex]

To simplify this expressiοn, we first distribute the negative sign to the terms inside the parentheses:

[tex](f-g)(x) = 2x^2 - 3x + 1 - 4x^2 - 2x + 3[/tex]

Next, we cοmbine like terms:

[tex](f-g)(x) = -2x^2 - 5x + 4[/tex]

Therefore, The value of (f-g)(x) when [tex]f(x)=2x^2-3x+1[/tex] and [tex]g(x)= 4x^2+2x-3[/tex] , is equals to [tex]-2x^2 - 5x + 4.[/tex]

The events H1 and H2 are independent.

Let P(B) be the probability that the selected coin is the biased one. Since we're picking the coin at random, P(B) = 0.5. Now, suppose we get two heads in a row. Let's call this event E. If E happens and the coin we picked is the biased coin, then the probability of getting two heads in a row is given by the probability that the biased coin gives heads twice, which is (2/3)² = 4/9. Therefore, the probability that we picked the biased coin given that we got two heads in a row is: P(B|E) = P(E|B)P(B) / [P(E|B)P(B) + P(E|F)P(F)], where F is the event that the fair coin is chosen. Note that the probability of getting two heads in a row with the fair coin is 1/4. Hence, the above formula becomes P(B|E) = (4/9 x 0.5) / [(4/9 x 0.5) + (1/4 x 0.5)] = 16/29. Therefore, the probability that we picked the biased coin given that we got two heads in a row is 16/29. b) The outcomes are independent given the picked coin, hence P(H1 ∩ H2) = P(H1)P(H2). Therefore, the events H1 and H2 are independent.

The correct option is d. If the correlation coefficient r is equal to 0.521, the coefficient of non-determination is 0.271.

Correlation is a term used to describe the relationship between two variables in a statistical context. The correlation coefficient is a measure of the strength and direction of the relationship between two variables.

The coefficient of non-determination is used in statistics to refer to the proportion of variability in one variable that is not accounted for by another variable. It is equal to 1 - r², where r is the correlation coefficient between the two variables.

So, the coefficient of non-determination can be found using the formula:

Coefficient of non-determination = 1 - r²Given that the correlation coefficient, r = 0.521, substitute the value in the formula to find the coefficient of non-determination:

Coefficient of non-determination = 1 - (0.521)²= 1 - 0.271 = 0.729

Steve should leave his house no later than 8:49 am (10:00 am minus 529 minutes) to get to work on time.

It's preferable to spell out the term minutes entirely rather than shorten it. Sixty seconds make up one minute, which is a measure of time. Minutes are a noun that also refers to the records of a formal meeting. The abbreviation "min" is frequently used.

Let's call the hour Steve needs to leave his house to leave for work "x".

He needs 9 minutes to walk from his home to the bus stop, and we don't know how long it will take the bus to get from Birmingham to Coventry. Call the length of the bus ride "t" for now.

Steve needs 12 minutes to walk to work from the bus stop in Coventry.

So, Steve's commute to work takes a total of:

Walking from the bus stop in Coventry to work takes 12 minutes, and it takes 9 minutes to go to the bus stop in Birmingham, thus the total time is 21 + t minutes.

Steve needs to arrive at work by 10 a.m., or 10 x 60 = 600 minutes.

Thus, we can formulate the equation shown below:

x + 21 + t <= 600

After finding x, we obtain:

x <= 579 - t

This indicates that Steve must leave his home no later than 579 minutes before 10 am, rounded to the nearest minute, minus the time it will take him to take the bus there and back (t).

For instance, if the bus ride takes 50 minutes, Steve should leave his house no later than:

x <= 579 - 50 = 529

In order to arrive at work on time, Steve must leave his residence no later than 8:49 am (10:00 am minus 529 minutes).

The total cost of the house we can afford is $⁢242,139.78.

What is compound interest?

Compound interest is when you earn interest on both the money you've saved and the interest you earn.

First, we need to determine the maximum monthly payment we can afford based on the recommended guidelines. If we can only spend 1414 of our take-home pay on a house payment, then:

Monthly payment = 0.45 × take-home pay

1414 = 0.45 × 3160

1414 = 1422

Therefore, we can afford a maximum monthly payment of $⁢1422.

Next, we can use the present value formula to find the maximum loan amount we can afford:

Loan amount = (monthly payment / monthly interest rate) × (1 - (1 + monthly interest rate)^(-n))

where monthly interest rate = 4.35% / 12 = 0.003625, and n = 15 years × 12 months/year = 180 months.

Substituting the values, we get:

Loan amount = (1422 / 0.003625) × (1 - (1 + 0.003625)^(-180))

Loan amount = $⁢225,739.78

Therefore, the maximum cost of the house we can afford with a 15-year mortgage is $⁢225,739.78 + $⁢16,400 (down payment) = $⁢242,139.78. Rounded to the nearest cent, the total cost of the house we can afford is $⁢242,139.78.

Therefore , the solution of the given problem of parallelograms comes out to be s intended, overline DE and overline FB are congruent.

In Euclidean mathematics, a simple quadrilateral of two sets of equal distances is referred to as a parallelogram. In a specific kind of quadrilateral known as a parallelogram, both set of opposite sides are straight and equal. There are four types of parallelograms, 3 of which are each mutually exclusive. Rhombuses, parallelograms, squares, but also rectangles are the four distinct shapes.

Here,

We can use the midpoint theorem and the fact that the opposing sides of a parallelogram are parallel and congruent to demonstrate that overline DE is congruent with overline FB.

The midpoint theory tells us that DE EA because we first know that E is the midpoint of overline AB.

The midpoint theory tells us that BF FC because we also know that F is the midpoint of overline DC.

As a result, overline DE and overline BC are parallel, and overline BF and overline AD are parallel.

DE EA and BF FC resulted in:

=> FC = EA Plus DE (Preserving equality by adding identical lengths)

If we replace FC with EA and DE with BF, we get:

=> BF + FC = DE + DE

If we simplify, we get:

=> 2DE = 2BF

When you divide both parts by 2, you get:

=> DE = BF

We have thus demonstrated that, as intended, overline DE and overline FB are congruent.

Given that, sin(x) = −1/√5
We know that sin x = y/r, where y is the opposite side and r is the hypotenuse. Since x is in the third quadrant, y is negative and r is positive, so we can draw a triangle in the third quadrant like the one below:

pair A = (-1,0);
pair B = (-0.6,-0.8);
pair C = (0,-0.8);

label("$x$",(C+B)/2,E);
label("$r$",(C)/2,NW);
label("$y$",(A)/2,S);

Here, $y=-1$, $r=\sqrt{5}$ and $x$ is the angle opposite to the side $y$. Using the Pythagorean theorem, we can find that the adjacent side is $x = -\sqrt{5 - 1} = -\sqrt{4} = -2$. Therefore,
$$
\cos(x) = \frac{x}{r} = \frac{-2}{\sqrt{5}} = -\frac{2\sqrt{5}}{5}
$$
Using the double angle formulas for sine and cosine,
$$
\begin{aligned}
\sin(2x) &= 2\sin(x)\cos(x)\\
&= 2\cdot \left(-\frac{1}{\sqrt{5}}\right) \cdot \left(-\frac{2\sqrt{5}}{5}\right)\\

In mathematics, ratios demonstrate how often one number is included in another. If there are 8 oranges and 6 lemons in a fruit bowl, the ratio of oranges to lemons is 8 to 6. In a similar vein, the ratio of oranges to whole fruit is 8, whereas the ratio of lemons to oranges is 6:8. A ratio is an ordered pair of integers a and b represented as a / b, where b is not equal to zero. A ratio is an equation that equals two ratios. For example, if there is 1 male and 3 girls (for every boy she has 3 girls), 3/4 are girls and 1/4 are boys.

One component cement, two parts sand, and three parts gravel are required to build dry concrete in the 1:2:3 ratio. This indicates that for every 1 kg of cement, 2 kg of sand and 3 kg of gravel are required.

To calculate the weight of one part, divide the entire weight of dry concrete (1200 kg) by the total number of parts (6). 1200 kg ÷ 6 = 200 kg.

Cement: 1 component cement (200 kilograms) = 200 kg

2 pieces sand 200 kilogram/part = 400 kg

Gravel: 600 kg = 3 parts gravel 200 kg/part
