∠1 and ∠2 are right angles because the measure of both angles is 90° and supplementary angles because the sum of both angles is 180°.

A triangle is a polygon that has three sides and three angles and the sum of the angle of the triangle is 180 degrees.

The figure is attached in the picture, please refer to the attached picture.

Given that:

So,

\(\angle2 = 90^\circ\) (vertically opposite angles are equal)

\(\angle1 + \angle2 = 180^\circ\) (Linear Pair)

\(\angle1 = 180 - 90\)

\(\angle1 = 90^\circ\)

\(\angle1 = \angle2 = 90^\circ\)

So, ∠1 and ∠2 are right angles because measure of both angles is 90°.

Adjacent angles because both a common arm and a common vertex.

Thus, ∠1 and ∠2 are right angles because the measure of both angles is 90° and supplementary angles because the sum of both angles is 180°.

Let

number of children admitted = x

number of adult admitted = y

Total number admitted = 335

number of children = 160

number of adult = 175

To determine the number of Mg2+ and PO3−4 ions required to form a neutral ionic compound, we need to consider the charges of the ions and their ratio in the compound.

In an ionic compound, the total positive charge must equal the total negative charge to achieve electrical neutrality. The Mg2+ ion has a charge of +2, indicating a loss of two electrons, while the PO3−4 ion has a charge of -3, indicating a gain of three electrons.

To form a neutral compound, the positive and negative charges must balance out. Since the charge of the Mg2+ ion is +2 and the charge of the PO3−4 ion is -3, the ratio between them must be such that the charges cancel out. This can be achieved by having three Mg2+ ions for every two PO3−4 ions.

Therefore, the number of Mg2+ ions required is three times the number of PO3−4 ions in order to achieve electrical neutrality in the compound.

It is important to note that the specific ratio and number of ions required may vary depending on the specific compound and its formula.

Answer: I’m pretty sure is letter A

according to question the final equation is:

(y - k)^2/(9/4) - (x - h)^2/16 = 1

The equation of a hyperbola centered at the origin with a vertical transverse axis of length 2a and a conjugate axis of length 2b is:

y^2/a^2 - x^2/b^2 = 1

Since the center is not at the origin, we need to use a slightly modified equation. If the center of the hyperbola is at (h, k), then the equation becomes:

(y - k)^2/a^2 - (x - h)^2/b^2 = 1

In this case, the center is not given, so we cannot write the full equation. However, we can write the equation of the hyperbola if we assume that the center is at the origin (0,0) and then shift it later.

Given that the length of the vertical transverse axis is 3, we know that 2a = 3, so a = 3/2. Similarly, since the length of the conjugate axis is 8, we know that 2b = 8, so b = 4.

Therefore, assuming that the center of the hyperbola is at the origin, the equation of the hyperbola is:

y^2/(9/4) - x^2/16 = 1

To shift the center of the hyperbola to a different point (h,k), we replace x with (x - h) and y with (y - k),

The slope of this line is the average rate of change of the function g(t) over the interval [a, b].

The average rate of change of a function g(t) over an interval [a, b] is defined as:

average rate of change = [g(b) - g(a)] / [b - a]

This represents the slope of the secant line between the points (a, g(a)) and (b, g(b)) on the graph of the function g(t).

Geometrically, the secant line is a straight line that passes through two points on a curve. In this case, it is the line that passes through (a, g(a)) and (b, g(b)). The slope of this line is the average rate of change of the function g(t) over the interval [a, b].

Note that the average rate of change gives us information about the overall trend of the function over the interval [a, b], but it does not tell us about the behavior of the function at any particular point within the interval.

Answer:

6435 ways

Step-by-step explanation:

Since the order does not matter, it is a combination, also because they do not indicate how many men and how many women should be in the group of 8, which means that it would be the ways of putting together a group of 8 with 15 people (10 men + 5 women)

That is to say:

nCr = n! / (r! * (n-r)!)

n = 15, r = 8, replacing:

15C8 = 15! / (8! * (15-8)!)

15C8 = 6435

which means that there are 6435 ways to arm the group

Taylor series is \(f(x) = ln2 + \sum_{n=1)^{\infty}(-1)^{n-1} \frac{(n-1)!}{n!(9)^{n}(x9)^{2} }\)

To find the Taylor series for f(x) = ln(x) centering at 9, we need to observe the pattern for the first four derivatives of f(x). From there, we can create a general equation for f(n). Starting with f(x), we have

f(x) = ln(x)

\(f^{1}(x)= \frac{1}{x} \\f^{2}(x)= -\frac{1}{x^{2} }\\f^{3}(x)= -\frac{2}{x^{3} }\\f^{4}(x)= \frac{-6}{x^{4} }\)

.

.

.

Since we need to have it centered at 9, we must take the value of f(9), and so on.

f(9) = ln(9)

\(f^{1}(9)= \frac{1}{9} \\f^{2}(9)= -\frac{1}{9^{2} }\\f^{3}(x)= -\frac{1(2)}{9^{3} }\\f^{4}(x)= \frac{-1(2)(3)}{9^{4} }\)

.

.

.

Following the pattern, we can see that for \(f^{n}(x)\),

\(f^{n}(x)=(-1)^{n-1}\frac{1.2.3.4.5...........(n-1)}{9^{n} } \\f^{n}(x)=(-1)^{n-1}\frac{(n-1)!}{9^{n}}\)

This applies for n ≥ 1, Expressing f(x) in summation, we have

\(\sum_{n=0}^{\infinite} \frac{f^{n}(9) }{n!} (x-9)^{2}\)

Combining ln2 with the rest of series, we have

\(f(x) = ln2 + \sum_{n=1)^{\infty}(-1)^{n-1} \frac{(n-1)!}{n!(9)^{n}(x9)^{2} }\)

Taylor series is \(f(x) = ln2 + \sum_{n=1)^{\infty}(-1)^{n-1} \frac{(n-1)!}{n!(9)^{n}(x9)^{2} }\)

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

There is a 12% discount because of the Happy Easter Sale and another 5% discount because the purchaser is a valued customer. After these discounts the GST increases the price by 10%.

Here, the customer paid $14 000.

Now, Let the original price = x

Hence, We can formulate;

⇒ x - (12% of x) - 5% of x + 10% of x = 14,000

⇒ x - 12x/100 - 5x/100 + 10x/100 = 14,000

⇒ (100x - 12x - 5x + 10x) / 100 = 14,000

⇒ 93x/100 = 14,000

⇒ 93x = 1400000

⇒ x = $15,024
