The sum of the first 9 terms of the series 75, 60, 48 can be found using the formula for the sum of an arithmetic series. The sum is equal to the average of the first and last terms, multiplied by the number of terms. Therefore, the sum of the first 9 terms of the series is 367.

The given series is not an arithmetic sequence with a common difference, so we cannot directly apply the formula for the sum of an arithmetic series. However, we can still find the sum by manually adding the terms or by observing a pattern.

The series can be rewritten as 75, 60, 48, 39, 33, 30, 30, 33, 39. From this pattern, we can see that the terms alternate between decreasing and increasing values. The sum of the first 9 terms can be calculated by adding the terms together:

75 + 60 + 48 + 39 + 33 + 30 + 30 + 33 + 39 = 367

Therefore, the sum of the first 9 terms of the series is 367.

We get the squares of the number as 1 , 4 , 9 , 16.......as given below, hence we get square of any number by product with itself.

The outcome of multiplying an integer by itself is referred to as the resultant number's square. In essence, a square number is a result of multiplying two identical numbers. The best illustration of a square number in geometry is the area of a square with side lengths of "n" (where n is an integer).

As an illustration, (-7)² = -7 -7 = 49 (two negative signs multiplied by each other result in a positive sign). The value of multiplying -7 and -7 is 49, which is a positive square number.

QN, LR and PM are the medians and they intersect each other at point K which will be the centroid of ΔPQR.

By the property of centroid,

Point K will divide the medians in the ratio of 2 : 1

By this property,

PK : KM = 2 : 1

4 : KM = 2 : 1

\(\frac{4}{KM}=\frac{2}{1}\)

KM = 2

KQ = \(\frac{2}{(2+1)}(NQ)\)

     = \(\frac{2}{3}\times 6\)

KQ = 4

LK : RK = 1 : 2

LK : 3 = 1 : 2

\(\frac{LK}{3}=\frac{1}{2}\)

LK = 1.5

LR = LK + RK

     = 1.5 + 3

LR = 4.5

NK = \(\frac{1}{(2+1)}(QN)\)

     = \(\frac{1}{3}(6)\)

NK = 6

PM = PK + KM

PM = 4 + 2

Let Cesar's, Carmen's and Dalila's amount be represented by x, y and z respectfully.

Since they're money sum up to $95.34, the first expression will be;

x+y+z=95.34

Carmen_y_ is $12.12 less than cesar_x, so the equation will be ;

y=x-12.12

Cesar_x_raised $35more than Dalila_z. So the equation will be;

x=z+35

making z the subject, z=x-35 .

Substituting the Second equation into the first one, we get;

x+x-12.12+z=95.34

Subtracting the third equation into the new equation we get;

x+x-12.12+x-35=95.34

Simplifying, we get 3x- 47.12= 95.34.

3x=142.46

The pseudo-order rate constant, or apparent rate constant, in equation (3) refers to a rate constant that appears in a pseudo-order rate law. It is called "pseudo" because it does not represent the true reaction order but is an effective rate constant obtained under specific conditions.

In the rate law for the reaction cC + dD → products, the rate is expressed as rate = k(C)^α(D)^β, where α and β are the unknown reaction orders.

a) The rate law for this reaction will be a pseudo β-order law in (D) when the concentration of D remains much larger than the concentration of C throughout the reaction. In other words, if the concentration of D is in excess compared to C, then the rate becomes solely dependent on the concentration of C, resulting in a pseudo β-order rate law.

b) To determine the value of β using the method of isolation, a series of experiments can be conducted.

If β is equal to 1, the reaction rate would be directly proportional to the concentration of D. By varying the concentration of D while keeping the concentration of C constant, multiple experiments can be performed, and the corresponding rates can be measured. Plotting the rate versus the concentration of D on a graph would yield a straight line with a slope of β, indicating that β is equal to 1.

If β is equal to 2, the reaction rate would be proportional to the square of the concentration of D. Similar to the previous case, different experiments can be carried out by changing the concentration of D while keeping C constant. The obtained rates can be plotted against the square of the concentration of D. If the resulting graph shows a straight line with a slope of β, it indicates that β is equal to 2.

Analyzing the experimental data and observing the relationship between the rate and the concentration of D in each case allows the determination of the value of β in the rate law.

Answer:

119 is the value of x when y = 7

Step-by-step explanation:

Since y varies inversely with x, we can use the following equation to model this:

y = k/x, where

Step 1:  Find k by plugging in values:

Before we can find the value of x when y = k, we'll first need to find k, the constant of proportionality.  We can find k by plugging in 49 for y and 17 for x:

Plugging in the values in the inverse variation equation gives us:

49 = k/17

Solve for k by multiplying both sides by 17:

(49 = k / 17) * 17

833 = k

Thus, the constant of proportionality (k) is 833.

Step 2:  Find x when y = k by plugging in 7 for y and 833 for k in the inverse variation equation:

Plugging in the values in the inverse variation gives us:

7 = 833/x

Multiplying both sides by x gives us:

(7 = 833/x) * x

7x = 833

Dividing both sides by 7 gives us:

(7x = 833) / 7

x = 119

Thus, 119 is the value of x when y = 7.

Step-by-step explanation:

The two missing angles of the quadrilateral are 10.5° and 2.47°, calculated from the given angles of 232° and 86°, and a ratio of 4:17.

The angle sum of a quadrilateral is 360°. Therefore, we need to find the sum of the two missing angles.We can start by subtracting the two known angles from the total angle sum and then dividing the difference by the ratio given.

360° - 232° - 86° = 42°

To find the two missing angles, divide the sum by the ratio given.

42° ÷ 4:17

The find the measure of the first angle, divide 42° by 4:

42° ÷ 4 = 10.5°

To find the measure of the second angle, divide 42° by 17:

42° ÷ 17 = 2.47°

Therefore, the two missing angles of the quadrilateral are 10.5° and 2.47°.

The z-values for the given situations are approximate:

a. The area to the left of z is 0.1827. z = -0.90

b. The area between −z and z is 0.9830. z = 2.17

c. The area between −z and z is 0.2148. z = 0.85

d. The area to the left of z is 0.9997. z = 3.49

e. The area to the right of z is 0.6847. z= -0.48

a. For an area of 0.1827 to the left of z, the corresponding z-value can be found using a standard normal distribution table or a statistical calculator. The z-value is approximately -0.90.

b. To find the z-value for an area between -z and z equal to 0.9830, we need to find the value that corresponds to (1 - 0.9830)/2 = 0.0085 in the upper tail of the standard normal distribution. Using the table or calculator, the z-value is approximately 2.17.

c. Similarly, for an area between -z and z equal to 0.2148, we find the value that corresponds to (1 - 0.2148)/2 = 0.3926 in the upper tail. The z-value is approximately 0.85.

d. For an area of 0.9997 to the left of z, we find the value that corresponds to 0.9997 in the upper tail. The z-value is approximately 3.49.

e. To find the z-value for an area to the right of z equal to 0.6847, we find the value that corresponds to 1 - 0.6847 = 0.3153 in the upper tail. The z-value is approximately -0.48.

In summary, the z-values for the given situations are approximate:

a. -0.90

b. 2.17

c. 0.85

d. 3.49

e. -0.48

These values can be used to determine the corresponding percentiles or probabilities for the standard normal distribution.

To determine whether triangle ABC is a right-angled triangle, we need to apply the Pythagorean Theorem.Pythagorean Theorem states that "In a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides."Let us assume that AC is the hypotenuse of the triangle ABC and let x be the length of AC.Using the Pythagorean theorem, we have:x² = AB² + BC²x² = 8² + 5²x² = 64 + 25x² = 89x = √89Hence, the length of AC is √89cm. Now, let us check if the triangle ABC is a right-angled triangle.Using the Pythagorean theorem, we have:AC² = AB² + BC²AC² = 8² + 5²AC² = 64 + 25AC² = 89AC = √89As we can see, the length of AC obtained from the Pythagorean theorem is the same as the one obtained earlier.So, the triangle ABC is not a right-angled triangle because it does not satisfy the Pythagorean theorem. Therefore, we can conclude that triangle ABC is not a right-angled triangle.

22-(8+5)=9cm

Now, using the Pythagorean theorem,
