Answer:

m∠D = 109

Step-by-step explanation:

This is a parallelogram.

In parallelograms, the opposite interior angles are congruent, so we can write the following equation to find, first value x the measure of m∠D:

9x - 44 = 6x + 7

9x - 6x = 7 + 44

3x = 51

x = 17

Now we can calculate measure of m∠D:

m∠D = 9x - 44

9×17 + 44 = 109

The Difference in the amounts that Tsion and Ibrahim paid for their watches is £3.85.

To find the difference in the amounts that Tsion and Ibrahim paid for their watches, we need to convert the prices to the same currency. We can use the exchange rates given to convert both prices to pounds.

1 Singapore dollar = £0.58

72 Singapore dollars = 72 x £0.58 = £41.76

1 Hong Kong dollar = £0.09

399 Hong Kong dollars = 399 x £0.095 = £37.91

Therefore, Tsion paid £41.76 for the watch and Ibrahim paid £37.91 for the same model of watch.

To find the difference in the amounts paid, we can subtract the smaller amount from the larger amount:

£41.76 - £37.91 = £3.85

Therefore, the difference in the amounts that Tsion and Ibrahim paid for their watches is £3.85.

Step-by-step explanation:

Subtract 1/8 from 1/2

12 - 18 is 38.

Steps for subtracting fractions

Find the least common denominator or LCM of the two denominators:

LCM of 2 and 8 is 8

Next, find the equivalent fraction of both fractional numbers with denominator 8

For the 1st fraction, since 2 × 4 = 8,

12 = 1 × 42 × 4 = 48

Likewise, for the 2nd fraction, since 8 × 1 = 8,

18 = 1 × 18 × 1 = 18

Subtract the two like fractions:

48 - 18 = 4 - 18 = 38

The value of x is 4.47 units

In the given figure, there are two right angle triangle, to find the value of x we have to solve each triangle using the Pythagorean theorem.

Consider the bottom triangle

Base of the triangle = 6 units

The hypotenuse of the triangle = 9 units

Apply the Pythagorean theorem

The third side of the triangle = \(\sqrt{9^2-6^2}\)

= \(\sqrt{81-36}\)

= \(\sqrt{45}\) units

Similarly consider the top triangle

The base of the triangle = 5 units

The hypotenuse of the triangle = \(\sqrt{45}\) units

The third side of the triangle = \(\sqrt{\sqrt{45}^2- 5^2}\)

= \(\sqrt{45-25}\)

= \(\sqrt{20}\)

= 4.47 units

Hence, the value of x is 4.47 units

The value of x IS 5/2.

The value of y is 9/16.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

x = 8y - 2 _____(1)

x + 8y = 7 ______(2)

Substitute (1) in (2).

8y - 2 + 8y = 7

16y - 2 = 7

16y = 7 + 2

16y = 9

y = 9/16

Now,

Substitute y = 9/16 in (1).

x = 8 x 9/16 - 2

x = 9/2 - 2

x = (9 - 4) / 2

x = 5/2

Thus,

The value of x and y are 5/2 and 9/16.

The requried to calculate an F ratio, we need to perform an analysis of variance (ANOVA) test.

To calculate an F ratio, we need to perform an analysis of variance (ANOVA) test. The F ratio is the ratio of two variances, and it is calculated by dividing the mean square of the between-group variability by the mean square of the within-group variability.

The formula for the F ratio is:

F = MSB / MSW

Where MSB is the mean square of the between-group variability and MSW is the mean square of the within-group variability.

The F ratio is used to test the null hypothesis that the means of the groups are equal. If the F ratio is greater than the critical value for a given level of significance (based on the degrees of freedom), we reject the null hypothesis and conclude that at least one group's mean is different from the others.

You can substract 10 from 100 ten times :)

Answer:

10

Step-by-step explanation:

100 - 10 = 90 ( 1 )

90 - 10 = 80 ( 2 )

80 - 10 = 70 ( 3 )

70 - 10 = 60 ( 4 )

60 - 10 = 50 ( 5 )

50 - 10 = 40 ( 6 )

40 - 10 = 30 ( 7 )

30 - 10 = 20 ( 8 )

20 - 10 = 10 ( 9 )

10 - 10 = 0 ( 10 )

we subtract 10 from 100 10 times

Choice B: Only (-1,-5)

Step-by-step explanation:

With this one, first the equation needs to be reduced into point-slope format.

y+5=2(x+1)

Distributive Prop.

y+5=2x+2

Carry over the 5 to the opposite side.

y=2x-3

Now, with the point slope form, it makes it easier to plug in the question choices to find which if any are correct.

Choice A: X is 5; Y is 10

y=2x-3

y=2(5)-3

y=10-3

y=7

This does not give a y value of 10, so it is false.

Choice B: X is -1; Y is -5

y=2(x)-3

y=2(-1)-3

y= -2-3

y= -5

This does give a y value of -5, so it is true. Choices C and D are therefore false as well, since only Choice B works.

The difference between the starting and ending grades is 0.90%

The time for integer (INT) operations reduced if the total time is reduced by 20% is 0.6667

The number of full (+00) stations on the curve is 66,666.

The difference between the starting and ending grades can be calculated as follows:

Difference = Ending Grade - Starting Grade

Difference = -2.85% - (-3.75%)

Difference = -2.85% + 3.75%

Now, let's perform the calculation:

Difference = 0.90%

Next, we need to determine the number of full stations on the curve. To do this, we divide the length of the curve by the rate of change of grade per station. The rate of change of grade per station is the difference between the starting and ending grades.

Length of Curve = 600 feet

Rate of Change of Grade per Station = Difference

Now, let's calculate the number of full stations:

Number of Full Stations = Length of Curve / Rate of Change of Grade per Station

Number of Full Stations = 600 feet / 0.90% = 0.6667

To convert the rate of change of grade from a percentage to a decimal, we divide by 100:

Number of Full Stations = 600 feet / (0.90% / 100)

Number of Full Stations = 600 feet / (0.0090)

Calculating this expression gives us the number of full stations on the curve.

Number of Full Stations = 66,666.67

Therefore, we round down the number of full stations to the nearest whole number, which gives us:

Number of Full Stations = 66,666 (rounded down)

As given by the question , so here the vertical and horizontal asymptotes are at x = -12 and y = 1.5.

On a function graph, a vertical asymptote represents the point at which the function is undefined. Take the formula f(x) = 1/x as an illustration. This function's graph exhibits a vertical asymptote at x = 0 since the function is undefined at this value (division by 0 is undefined).

A function's horizontal asymptote is a horizontal line on the function graph that the function approaches as the input (x-value) increases or decreases dramatically. Consider the function f(x) = x2 as an illustration. Because the y-values of the function do not converge to a fixed value as x grows very big, the graph of this function lacks a horizontal asymptote.

We must identify the values of x at which the function is undefined in order to determine the vertical asymptotes of the function 3x/(2x+24).So, to find the vertical asymptotes of the function, we need to solve the equation 2x + 24 = 0 for x. so x = -12.

Similarly, To find the horizontal asymptote in case of equal degrees of numerator and denominator i.e 1 in this case, we need to take the ratio of the first coefficients of numerator and denominator respectively which is 3/2 = 1.5.

Option b. f(x) = (x + 3)² - 1 represents the given graph based on its matching shape, vertex, and direction of opening.

Based on the options provided, the function that represents the graph above is b. f(x)=(x+3)²-1.

To determine the correct option, let's analyze the given graph. We observe that the graph is a parabola that opens upward and has its vertex at the point (-3, -1).

This vertex represents the lowest point on the graph.

The general form of a quadratic function (parabola) is f(x) = ax^2 + bx + c, where a, b, and c are constants.

Comparing the graph to the options provided:

a. f(x) = -(x + 3)² - 1:

This option is incorrect because it has a negative sign in front of the squared term, which would result in a downward opening parabola. However, the given graph shows an upward opening parabola.

b. f(x) = (x + 3)² - 1: This option is correct because it matches the form of the graph, with the squared term (x + 3)² resulting in an upward opening parabola.

The vertex form of this function is f(x) = a(x - h)² + k, where (h, k) represents the coordinates of the vertex. In this case, (h, k) = (-3, -1).

c. f(x) = (x - 3)² - 1: This option is incorrect because it has a different value for the x-coordinate of the vertex.

The given graph shows the vertex at (-3, -1), not (3, -1).

The language \(\bar L\) is the complement of the language L. It consists of all strings over the alphabet Σ= {a,b} that are not in L.

The language L is defined as L= {λ,a,b,aa,bb,ab,ba}. To find the complement of L, we need to determine all the strings that are not in L.

The alphabet Σ= {a,b} consists of two symbols: 'a' and 'b'.

Therefore, any string not present in L must contain either symbols other than 'a' and 'b', or it may have a different length than the strings in L.

The complement of L, denoted by \(\bar L\). includes all strings over Σ that are not in L.

In this case, \(\bar L\) contains strings such as 'aaa', 'bbbb', 'ababab', 'bbba', and so on.
