Step-by-step explanation:

The value for the hotspots of the similar triangles ∆ABC and ∆PWR are:

(1). angle B = 68°

(2). PQ = 5cm

(3). BC = 19.5cm

(4). area of ∆PQR = 30cm²

Similar triangles are two triangles that have the same shape, but not necessarily the same size. This means that corresponding angles of the two triangles are equal, and corresponding sides are in proportion.

(1). angle B = 180 - (22 + 90) {sum of interior angles of a triangle}

angle B = 68°

Given that the triangle ∆ABC is similar to the triangle ∆PQR.

(2). PQ/7.5cm = 12cm/18cm

PQ = (12cm × 7.5cm)/18cm {cross multiplication}

PQ = 5cm

(3). 13cm/BC = 12cm/18cm

BC = (13cm × 18cm)/12cm {cross multiplication}

BC = 19.5cm

(4). area of ∆PQR = 1/2 × 12cm × 5cm

area of ∆PQR = 6cm × 5cm

area of ∆PQR = 30cm²

Therefore, the value for the hotspots of the similar triangles ∆ABC and ∆PWR are:

(1). angle B = 68°

(2). PQ = 5cm

(3). BC = 19.5cm

(4). area of ∆PQR = 30cm²

The new coordinates of the image include the following:

W' (-1, 1)

X' (4, -1)

Y' (4, -5)

Z' (1, -7)

In Mathematics and Geometry, a reflection over or across the x-axis is represented by this transformation rule (x, y) → (x, -y). This ultimately implies that, a reflection over or across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate changes from positive to negative or negative to positive.

Next, we would apply a reflection over or across the x-axis to quadrilateral WXYZ;

(x, y)                →      (x, -y)

W (-1, -1)         →      (-1, -(-1)) = W' (-1, 1)

X (4, 1)           →      (4, -(1)) = X' (4, -1)

Y (4, 5)         →      (4, -(5)) = Y' (4, -5)

The length of the day in Manila, Philippines, varies periodically and can be modeled by a trigonometric function. The formula is l(t) = (779.607 - 675.856) xcos((2π/365) x (t - 111111)) + (779.607 + 675.856) / 2.

To model the variation in the length of the day in Manila, a trigonometric function is used, considering the period of change as exactly 365365365 days. The shortest day occurs on December 21, with a length of 675.85675.85675, point, 85 minutes, while the longest day occurs on June 21, with a length of 779.60779.60779, point, 60 minutes.

To find the formula for the trigonometric function, we need to consider the general form of a cosine function, which includes an amplitude, angular frequency, and phase shift. Here, the amplitude is (779.607 - 675.856), the angular frequency is (2π/365), and the phase shift is (t - 111111), where t represents the number of days after January 1.

Therefore, the formula for the length of the day can be expressed as l(t) = (779.607 - 675.856) xcos((2π/365) x (t - 111111)) + (779.607 + 675.856) / 2. This equation represents the variation in the day length throughout the year in Manila, with the cosine function capturing the periodic nature of the changes.

The probability of light being green ,yellow, not red ,and not green are 11/17, 1/17, 12/17 and 6/17 respectively.

Traffic light is red for 25 sec

Traffic light is yellow for 5 sec

Traffic light is green for 55 sec

Total of 85 seconds

The probability of the light being yellow when you reach it, all other things being equal, is 5 / 85 = 1/17

The probability of the light being green when you reach it, all other things being equal, is 55/ 85 = 11/17

The probability of the light being not red when you reach it, all other things being equal, is 5+55/ 85 = 60/85 = 12/17

The probability of the light being not green when you reach it, all other things being equal, is 5+25/ 85 = 30/85 = 6/17

As a result, the odds of a light being green, yellow, not red, or not green are respectively 11/17, 1/17, 12/17, and 6/17.

The median annual salary would be more useful to Jaime in making the decision between pursuing graduate studies or applying for a job.

The median annual salary represents the middle value in a salary distribution, which indicates the typical or central salary of college graduates in that profession. It is less affected by extreme values or outliers in the data. Therefore, the median provides a more reliable measure of the average salary that Jaime can expect as a college graduate. On the other hand, the mean annual salary can be influenced by a few individuals with exceptionally high or low salaries, which may not accurately reflect the typical salary range. Hence, the median salary would be a better indicator for Jaime to make an informed decision.

A function in mathematics from a set X to a set Y allocates precisely one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

Finding a function's derivative, or rate of change, is the process of differentiation in mathematics. The practical approach of differentiation may be performed utilizing just algebraic operations, three fundamental derivatives, four principles of operation, and an understanding of how to manipulate functions, in contrast to the theory's abstract character.

solution of above questions are:

a)Function 'f' has relative maximum at x=-2 because f'(x)=0 and f' is   changing from +ve to -ve

b) (-1,1 ) and (3,5) are intervals of graph that is concave upward  because f' is increasing and f'' is +ve.

The smallest sample size that will result in a margin of error of no more than 5% for a 95% confidence interval is given as follows:

385.

A confidence interval of proportions has the bounds given by the rule presented as follows:

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which the variables used to calculated these bounds are listed as follows:

The margin of error is modeled as follows:

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of \(\frac{1+0.95}{2} = 0.975\), so the critical value is z = 1.96.

We have no estimate, hence we consider that:

\(\pi = 0.5\)

The minimum sample size is obtained as n when M = 0.05, hence:

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

\(0.05 = 1.96\sqrt{\frac{0.5(0.5)}{n}}\)

\(0.05\sqrt{n} = 1.96 \times 0.5\)

\(\sqrt{n} = 1.96 \times 10\) (0.5/0.05 = 10).

\((\sqrt{n})^2 = (1.96 \times 10)^2\)

n = 384.16

Hence rounded to 385, as a sample size of 384 would have a margin of error slightly above 0.05.

Jose invests money in an account paying a simple interest of 9% per year, he should multiply his current balance by 9% to find his total balance.

Simple Interest is a simple way for computing interest on a loan or principle amount. The notion of simple interest is used in many sectors, including banking, finance, and vehicles. The monthly interest is deducted first, followed by the principal amount, when you make a loan payment.

We have rate of interest as 9%

So, SI = PNR/100

SI = P x 1 x 9/100

SI = P x 9%.

Therefore, current balance should be multiplied by 9% .

Simple Interest (S.I.) is a way of determining the amount of interest for a given principle amount. You put that money to use for the reason you borrowed it in the first place. The money is then returned after you receive your following month's pocket money from your parents. This is how borrowing and lending operate in the real world.
