The measure for x is 1.414 units.

The area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

Given:

Hypotenuse= 2

angle= 45

Using Trigonometry

cos 45 = B/ H

1/√2 = B/ 2

B = 2/√2

B = √2

The sum of the positive integers not exceeding 5 is 1 + 2 + 3 + 4 = 10

The proof of this statement is constructive, as it will provide a way to explicitly construct a positive integer which is equal to the sum of the positive integers not exceeding it.

To prove this, we will use the following formula:

Let n = the positive integer

Let S = the sum of the positive integers not exceeding n

n = 1 + 2 + ... +n-1 + n

S = 1 + 2 + ... +n-1

Therefore, n = S + n

For example, let n = 5. The sum of the positive integers not exceeding 5 is 1 + 2 + 3 + 4 = 10. Therefore, 5 = 10 + 5, which is true. This proves that for any positive integer, n, it is equal to the sum of the positive integers not exceeding it.

The probability is 0, 1/9, and 1/36 for getting a sum of 1, the sum of 5, and the sum of 12 occurs.

Probability is something that is to happen or a chance that an event will occur.

For two rolled dice, the total outcome is 6² = 36

Probability = Expected outcome/Total outcome

a) Pr of getting a sum of 1 = 0/36 = 0

we have a pair of dice, the least sum we can have is 2

b) The event that occurs a sum of 5 are (1, 4), (4, 1), (3, 2), (2, 3)

n(E) = 4

Pr of getting a sum of 5 = 4/36 = 1/9

c)The probability of getting a sum of 12 is (6, 6)

n(E) = 1

Pr of getting a sum of 12 = 1/36

Therefore, the probability that occurs a sum of 1, the sum of 5, and the sum of 12 are 0, 1/9, and 1/36 respectively.

The perimeter of the trapezoid is 50 cm.

A trapezoid, commonly referred to as a trapezium, is a quadrilateral or a polygon with four sides. It has a set of parallel opposing sides and a set of non-parallel sides. The bases and legs of the trapezoid are known as the parallel and non-parallel sides, respectively.

Given the trapezoid,

let us consider ABCD be the trapezoid,

so given angle B = 90°

The area of the shaded region of the semicircle is 108π mm²

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, a semicircle with a diameter of 24 mm, a circle is fitted in it, we need to find the measurement of the area which is shaded.

The diameter of the smaller circle = radius of semicircle.

Therefore,

Radius of smaller circle = 24/4 = 6 mm

To find the area of shaded region, we will subtract the area of the smaller circle from the area of semicircle.

Area of a circle = π × radius² {area of semicircle is just half of it}

Area of shaded region = π × 12² - π × 6²

= π(144-36)

= 108π

Hence, the area of the shaded region of the semicircle is 108π mm²

The initial value of the first investment was M = Rs.12,000,000 and the initial value of the second investment was N = Rs.16,000,000.

Let's assume the initial investment in the first investment be M and the initial investment in the second investment be N.

We know that the annual return from the first investment is 3% of M and the annual return from the second investment is 5% of N.

So, the total annual return (T) is:

T = 0.03M + 0.05N = 1160000

The investor increases his investment in the first investment by 25%, so the new investment in the first investment becomes:

M1 = M + 0.25M = 1.25M

And the new annual return from the first investment becomes:

R1 = 0.03 * 1.25M = 0.0375M

Similarly, the new investment in the second investment becomes:

N1 = N + 0.40N = 1.40N

And the new annual return from the second investment becomes:

R2 = 0.05 * 1.40N = 0.07N

So, the new total annual return (T1) is:

T1 = R1 + R2 = 0.0375M + 0.07N

And the increase in the total annual return is:

410,000 = T1 - T

We have 2 equations with 2 variables (M and N), so we can solve for them.

0.0375M + 0.07N = 0.03M + 0.05N + 410000

Expanding and solving the equation we get:

M = 12,000,000

N = 16,000,000

So, the initial value of the first investment was M = Rs.12,000,000 and the initial value of the second investment was N = Rs.16,000,000.

The most appropriate measure of spread for this data is standard deviation, because the boxplot is skewed to the right.

The most appropriate measure of spread for this data is standard deviation. The data is represented by a boxplot, which is a graphical representation of the data that shows the median, quartiles, and range of the data. In this case, the boxplot is skewed to the right, meaning that the data is not normally distributed. When the data is not normally distributed, the standard deviation is the best measure of spread to use. Standard deviation measures the spread of data by calculating the distance between each data point and the mean, and then taking the average of these distances. This allows us to accurately measure the spread of data that is not normally distributed. Therefore, standard deviation is the most appropriate measure of spread for this data.

The height of the plant A would be 95cm, while the height of the plant B would be 87 cm

We can use an equation to represent the height of each plant as a function of time t:

Plant A: h_A = 75 + 10t

Plant B: h_B = 55 + 12t

We want to find the time t at which the two plants will be the same height, so we can set the two equations equal to each other:

75 + 10t = 55 + 12t

Solving for t, we get:

10t = 20

t = 2

So, after 2 months, the two plants will be the same height. To find the height at that time, we can substitute t = 2 into either equation:

h_A = 75 + 10t = 75 + 10 * 2 = 95

h_B = 55 + 12t = 55 + 12 * 2 = 87

Answer:

the solution to the system is x = 1 and y = 5/2.

Step-by-step explanation:

To find the values of x and y, we can simplify each equation in the system and then substitute the value of x into the other equation to find y.

Starting with the first equation:

y - 1 = 3x / 2

2 * (y - 1) = 3x

3x = 2y - 2

Next, we substitute the value of 3x/2 from the first equation into the second equation:

5x + 1 = 4x

x = 1

Finally, we can substitute the value of x = 1 into the first equation to find y:

y - 1 = 3 * 1 / 2

y - 1 = 3 / 2

y = 5 / 2

So the solution to the system is x = 1 and y = 5/2.

The common ratio is calculated by dividing each term by its previous one.

The nth term formula for this particular geometric sequence is:

[tex]a_n = a*r^{n-1}\\\\a_n = 7*4^{n-1}\\\\[/tex]

The last step is to plug n = 8 into that formula.

[tex]a_n = a*r^{n-1}\\\\a_n = 7*4^{n-1}\\\\a_8 = 7*4^{8-1}\\\\a_8 = 7*4^{7}\\\\a_8 = 7*16384\\\\a_8 = 114688\\\\[/tex]

The 8th term is 114688

Avoid using commas to separate out the digits. This is because commas are used to separate each term of the geometric sequence.

8th term of this geometric sequence is 114,688.

In a geometric sequence, each term is found by multiplying the previous term by a common ratio. To find the 8th term, we need to know the common ratio and the first term. Given that the first term is 7 and the second term is 28, we can find the common ratio as follows:

r = 28/7 = 4

Now that we know the common ratio, we can find the 8th term by multiplying the first term by the common ratio raised to the power of 7:

a_8 = 7 * r^(8-1) = 7 * 4^7 = 7 * 16,384 = 114,688

Therefore, the 8th term of the sequence is 114,688.

On dilating the point X(6,5) with scale factor of -2, the value is obtained as X(-12,-10).

What is dilation?

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. The initial shape should be stretched or contracted during a dilatation.

The coordinate point for X is given as X(6,5).

The dilation is centered at the origin (0,0).

The dilation scale factor is given as -2.

To find the value of X' use the formula -

X(a,b) → X[(a×(-2)) , (b×(-2))]→ X'

Substitute the values in expression -

X(6,5) → X[(6×(-2)) , (5×(-2))]
