, What value of x will make the two triangles similar?

Answer:

z = 50°

Step-by-step explanation:

We know that,

→ Sum of all sides of triangle is 180°.

Formula we use,

→ <A + <B + <C = 180°

Forming the equation,

→ 60° + 70° + z = 180°

Now the value of z will be,

→ 60° + 70° + z = 180°

→ 130° + z = 180°

→ z = 180° - 130°

→ [ z = 50° ]

Hence, the value of z is 50°.

The coordinates of the triangle when translated 2 units left are A'(-3, -1), B'(-3, -5) and C'(-1.5, -5).

Translation is a type of transformation of geometrical figures. After translation, the original figure is shifted from a place to another place without affecting it's size.

The given triangle has the coordinates A(-1, -1), B(-1, -5) and C(0.5, -5).

Translation is done 2 units left.

A(-1, -1) becomes A(-1 - 2, -1) = (-3, -1)

B(-1, -5) becomes B(-1 - 2, -5) = (-3, -5)

∫1.5 T(h) dh = 9.573, rounded to three decimal places. (a) To evaluate ∫1.5 T(h) dh, we need to integrate T(h) with respect to h from 0 to 1.5: ∫1.5 T(h) dh = ∫0.1.5 (9.43h^3 - 15.41h^2 + 17.34h - 9.83) dh

Using the power rule of integration, we can integrate each term of the polynomial: ∫0.1.5 (9.43h^3 - 15.41h^2 + 17.34h - 9.83) dh

= (9.43/4)h^4 - (15.41/3)h^3 + (17.34/2)h^2 - 9.83h |0.1.5

= [(9.43/4)(1.5)^4 - (15.41/3)(1.5)^3 + (17.34/2)(1.5)^2 - 9.83(1.5)] - [(9.43/4)(0)^4 - (15.41/3)(0)^3 + (17.34/2)(0)^2 - 9.83(0)] = 9.573

Therefore, ∫1.5 T(h) dh = 9.573, rounded to three decimal places.

The rod's linear density at 1 metre from the left end and a point x meters to the right is 8 x 3 kg is = 8(1)2 = 8 kg/m.

We can start by using the definition of linear density, which is the mass per unit length of a rod or wire. Let's assume that the linear density of the rod at a distance of 1 meter from the left end is ρ kg/m.

Then, the mass of the part of the rod that lies between 0 meters and 1 meter to the right is:

m1 = ρ * 1 kg

Similarly, the mass of the part of the rod that lies between 0 meters and x meters to the right is:

m2 = 8x^3 kg

The mass of the part of the rod that lies between 1 meter and x meters to the right is:

m2 - m1 = (8x^3 - ρ) kg

Since we know that this mass is equal to ρ times the length of the rod segment, which is (x-1) meters, we can write:

ρ * (x-1) = 8x^3 - ρ

By condensing this solution, we obtain:

ρ * (x-1+1) = 8x^3

ρ * x = 8x^3

ρ = 8x^2 kg/m

As a result, the rod's linear density at 1 metre from the left end is = 8(1)2 = 8 kg/m.

Step-by-step explanation:

The polynomial has real coefficients, so if it has a complex root, it must have at least two complex roots which are complex conjugates.

Since 1 + 3i is a root, then 1 - 3i is also a root.

Two of the factors of the polynomial are:

x - (1 + 3i) and x - (1 - 3i)

Simplify the factors above:

x - 1 - 3i and x - 1 + 3i

Find their product:

(x - 1 - 3i)(x - 1 + 3i) =

Rewrite them showing we have the product of  a sum and a difference.

= [(x - 1) - 3i][(x - 1) + 3i]

Multiply the factors above noticing they are a sum and a difference which follows the pattern (a + b)(a - b) = a² - b².

= (x - 1)² - (3i)²

= x² - 2x + 1 - 9(-1)

= x² - 2x + 10

Now we divide the original polynomial by the product we just found using long division.

                                        x - 4

                                  ------------------------------

         x² - 2x + 10      |    x³ - 6x² + 18x - 40

                                  -   x³ - 2x² + 10x

                                            -4x² + 8x - 40

                                      -     -4x² + 8x - 40

                                     --------------------------

                                                0 +    0  + 0

Now we know that x³ - 6x² + 18x - 40 factors into (x² - 2x + 10)(x - 4).

(x² - 2x + 10)(x - 4) = 0

From x² - 2x + 10, we have roots x = 1 + 3i and x = 1 - 3i.

x - 4 = 0

x = 4

From x - 4, we have root x = 4.

The proof method to show that the statement "The average of any three odd integers is an odd integer" is true is "Prove true by direct proof."

To prove that the statement is true by direct proof, we can assume that the three odd integers are a, b, and c, where a = 2k + 1, b = 2m + 1, and c = 2n + 1 for some integers k, m, and n. Then, the average of these three odd integers is:

(a + b + c)/3 = (2k + 1 + 2m + 1 + 2n + 1)/3

= (2k + 2m + 2n + 3)/3

= 2(k + m + n) + 1

Since k, m, and n are integers, k + m + n is also an integer. Therefore, the average of any three odd integers is of the form 2x + 1, where x is an integer, which is an odd integer.

The reason the attempted proof of the statement "The difference between any odd integer and any even integer is odd" is not correct is "The proof violates the parity property." The student incorrectly subtracted an even integer from an odd integer and concluded that the result is odd. However, the difference between an odd integer and an even integer is always odd, which can be proven directly as follows:

Let n be any odd integer and m be any even integer. Then, by definition, n = 2k + 1 and m = 2j for some integers k and j. The difference between n and m is:

n - m = (2k + 1) - 2j

= 2k - 2j + 1

= 2(k - j) + 1

Since k and j are integers, k - j is also an integer. Therefore, the difference between any odd integer and any even integer is of the form 2x + 1, where x is an integer, which is an odd integer.

By using fundamental theorem of calculus  The exact value of the definite integral [tex]\int {1}^{\pi}\left(3x^{-1} \sqrt{x}\right)\ dx[/tex] is 6(√(π) - 1).

First, we can find an antiderivative of the integrand by using the power rule and the constant multiple rule of integration:

∫(3x^(-1/2)) dx = 3 ∫(x^(-1/2)) dx = 3 (2x^(1/2)) + C = 6√(x) + C

where C is the constant of integration.

Now, we can use the fundamental theorem of calculus to evaluate the definite integral \int {1}^{\pi}\left(3x^{-1} \sqrt{x}\right)\ dx. The theorem states that if f(x) is continuous on the interval [a, b] and F(x) is an antiderivative of f(x), then

∫[a, b] f(x) dx = F(b) - F(a)

In this case, f(x) = 3x^(-1/2) and F(x) = 6√(x) + C. Therefore,

∫{1}^{π} (3x^(-1/2)) dx = F(π) - F(1) = 6√(π) + C - 6√(1) - C = 6√(π) - 6√(1) = 6(√(π) - 1)

we can conclude that the value of n for which [tex]t_n[/tex] = 0.3325 is between 3 and 4 and the value of n for which [tex]S_n[/tex]= -6 is 6.

A) To find the value of n for which [tex]t_n[/tex] = 0.3325, we can use trial and error method.

Starting with n=1, we have:

[tex]t_1 = (1^2 - 1)/(3 * 1^2) = 0[/tex]

For n=2, we have:

[tex]t_2 = (2^2 - 1)/(3 * 2^2) = (3)/(12) = 0.25[/tex]

For n=3, we have:

[tex]t_3 = (3^2 - 1)/(3 * 3^2) = (8)/(27) = 0.296296...[/tex]

Continuing in this way, we find that t_3 < 0.3325 < t_4, where

[tex]t_4 = (4^2 - 1)/(3 * 4^2) = (15)/(48) = 0.3125[/tex]

Thus, we can conclude that the value of n for which [tex]t_n[/tex] = 0.3325 is between 3 and 4, and it can be found more accurately by using numerical methods such as bisection or Newton's method.

B) To find the sum of the arithmetic series 16 + 13 + 10 + ..., we can use the formula for the sum of an arithmetic series:

[tex]S_n = n/2 * (a_1 + a_n),[/tex]

where n is the number of terms in the series, [tex]a_1[/tex] is the first term (16 in this case), and a_n is the nth term.

Let's assume that the nth term is represented by [tex]a_n = 16 - 3 * (n - 1),[/tex] so that a_1 = 16 and a_n = 16 - 3 * (n - 1).

Then, we have:

S_n = n/2 * (16 + 16 - 3 * (n - 1)) = n/2 * (16 + 16 - 3n + 3) = n/2 * (16 + 16 - 3n + 3) = n/2 * (32 - 3n + 3) = 16n - (3/2)n^2 + (3/2)n

We want to find the value of n for which S_n = -6, so we can substitute the value of S_n into the equation and solve for n:

[tex]S_n = n/2 * (16 + 16 - 3 * (n - 1)) = n/2 * (16 + 16 - 3n + 3) = n/2 * (16 + 16 - 3n + 3) = n/2 * (32 - 3n + 3) = 16n - (3/2)n^2 + (3/2)n[/tex]

[tex]-6 = 16n - (3/2)n^2 + (3/2)n[/tex]

Expanding the equation and solving for n, we find that n = 6.

The equation for a straight line is y−y1=m(x−x1)

where y1 is the Y-axis coordinate, m is the tilt, x1 Coordinates on the x-axis.  m = y2-y1/x2-x1

eqn = y +4 = (-36/1/4)(x-1/2)

y +4 = -146x + 73

y = -146x + 69

The fourth number ​is equal to -6.

Mathematically, the arithmetic average for a given data set can be calculated by using this formula:

Average = [F(x)]/n

Next, we would calculate the arithmetic average for the four numbers (data set) as follows:

Let the fourth number be represented by the variable n.

Total numbers = 17 + 13 + 16 + n

Total numbers = 46 + n

10 = 46 + n/4

40 = 46 + n

n = 40 - 46

n = -6
