The measure of the angle ∠ADC is 36°.
Given that a circle T, the inscribed angle ∠ABC = 72°, we need to find the measure of the angle ∠ADC,
So, according to the inscribed angle theorem,
2 ∠ABC = arc AC
arc AC = 144°
Now, since the whole circumference is 360°,
So,
arc ADC = 360° - arc AC
arc ADC = 216°
So,
∠ADC = 1/2 [arc ADC - arc AC]
∠ADC = 1/2 [216° - 144°]
∠ADC = 36°
Hence the measure of the angle ∠ADC is 36°.

A man had a square window with sides equal to 1 metre in his house. He decided that it lets in too much light, so he boarded up half of it and still had a square window 1 metre high and 1 metre wide. How did he do that? (6) Total: 40 marks
The man rotated the window by 45 degrees and covered one of the diagonals, resulting in a smaller square window with sides measuring 1 meter.
The man achieved the transformation of his square window by dividing it into two equal halves and boarding up one of them.
Let's analyze the steps he took to accomplish this:
Initially, the man had a square window with sides measuring 1 meter
This means that the window had an area of 1 square meter (1m x 1m = 1m²).
To reduce the amount of light coming through the window, the man decided to board up half of it.
This implies that he covered one of the equal halves of the square window, while leaving the other half open.
By boarding up half of the window, he effectively blocked off half of the area of the square window.
Since the original window had an area of 1 square meter, boarding up half of it reduces the effective area to 1/2 square meter (1m² ÷ 2 = 1/2m²).
The remaining open half of the window still retains its square shape, with sides equal to 1 meter.
Therefore, the man ends up with a square window that measures 1 meter in height and 1 meter in width, but with an area of only 1/2 square meter.
In summary, the man achieved the transformation by boarding up half of the square window, effectively reducing its area to half of the original size while maintaining the same dimensions for the remaining open half. This manipulation allows him to control the amount of light entering his house while preserving the square shape of the window.

The ordered pair that is a solution of the system is (-3, -3), the second option.
Which ordered pair is a solution of the system of inequalities?There are two ways of finding this.
You can use your graph and identify which of the given pointes lies in the region where the two shaded areas intersect.
Another way, is replacing the values of the coordinate points in both inequalities and checking that both are true when evaluated in the point.
Here we will use the graph, because you already had it (and you can see a more precise graph in the image at the end).

. Suppose a government agency has a monopoly in the provision of internet connections.
The marginal cost of providing internet connections is 1
2
, whereas the inverse demand
function is given by: p = 1
The government agency as a monopolist will produce and sell internet connections up to the point where the marginal cost is 1/2. The price will be set at 1, given the perfectly elastic demand function.
In the scenario where a government agency has a monopoly in the provision of internet connections and the inverse demand function is given by p = 1, we can analyze the market equilibrium and the implications for pricing and quantity.
The inverse demand function, p = 1, implies that the market demand for internet connections is perfectly elastic, meaning consumers are willing to purchase any quantity of internet connections at a price of 1. As a monopolist, the government agency has control over the supply of internet connections and can set the price to maximize its profits.
To determine the optimal pricing and quantity, the monopolist needs to consider the marginal cost of providing internet connections. In this case, the marginal cost is given as 1/2. The monopolist will aim to maximize its profits by equating marginal cost with marginal revenue.
Since the inverse demand function is p = 1, the revenue received by the monopolist for each unit sold is also 1. Therefore, the marginal revenue is also 1. The monopolist will produce up to the point where marginal cost equals marginal revenue, which in this case is 1/2.
As a result, the monopolist will produce and sell internet connections up to the quantity where the marginal cost is 1/2. The monopolist will set the price at 1 since consumers are willing to pay that price.

In 2020, the Ministry of Health, in a report on investment in infrastructure and equipment for health units (2007-2020), counted 2,074 health units (between new and improved). If the number of improved health units exceeds the new ones by 200, how many new and improved health units are shown in the report?
The number of new health units is 937, and the number of improved health units is 1,137.
The number of improved health units exceeds the new ones by 200. In other words, I = N + 200.
We also know that the total number of health units counted in the report is 2,074.
Therefore, we have the equation N + I = 2,074.
Substituting the value of I from the first equation into the second equation, we can solve for N:
N + N + 200 = 2,074
2N + 200 = 2,074
2N = 1,874
N = 937
Now, we can substitute the value of N back into the first equation to find I:
I = N + 200
I = 937 + 200
I = 1,137
Therefore, the number of new health units is 937, and the number of improved health units is 1,137.

A chord of a circle is 18cm long.it is 6.3cm from the center of the circle.calculate the radius of the circle to the nearest whole number?
Answer: The radius of the circle rounded to the nearest integer is 11 cm
Step-by-step explanation:
To resolve this issue we can utilize the properties inherent to circles along with Pythagoras' theorem while denoting our circle's radius as "r".
Given that we know of a chord of length equaling up to 18 cm placed at a distance measuring exactly 6.3 cm away from the center of our circle sketching out a diagram would make it easier for us to visualize such a situation. Once visualizing this problem statement through our aforementioned diagram we may approach it using Pythagoras' theorem and examine the components regarding the right-angled triangle formed by half-length chord radius "r" and distance between center and chord respectively.
Our calculations factor in measurements representing half of our chords length (which is equal to precisely 9cm) alongside distances measuring up to exactly 6.3cm while possessing "r" on one end as shown below:
r^2 = (6.3cm)^2 + (9cm)^2
Simplifying said equation leads us to have:
r^2 =39.69cm^2+81cm^2
r²=120.69cm²
Calculating square roots on both sides leads us towards the approximation of r equaling around:
r ≈ √120.69cm²
r ≈10.99cm
Therefore rounding off R towards its nearest whole number would give us R=11cm in this case scenario.

Sound waves travel through the air at approximately 343 meters per second. A tuba player plays a constant note that has a wavelength of 4.61 meters.
Determine the period of the sound wave created by the tuba in seconds.
The period of the sound wave created by the tuba is approximately 0.0134 seconds.
The speed of sound in air is given as 343 meters per second. The formula relating the speed of sound, wavelength, and period of a wave is:
v = λ × f
Where:
v = speed of sound (343 m/s)
λ = wavelength (4.61 m)
f = frequency (unknown)
To find the period, we need to determine the frequency of the sound wave. The period (T) is the reciprocal of the frequency (f), so we can rewrite the formula as:
v = λ / T
Rearranging the equation to solve for the period (T), we get:
T = λ / v
Substituting the given values, we have:
T = 4.61 m / 343 m/s
Calculating the value, we find:
T ≈ 0.0134 seconds
Therefore, the period of the sound wave created by the tuba is approximately 0.0134 seconds.
