Step-by-step explanation:

There are 3 balanced strings in set T.

To count the number of balanced strings in the set T={0, 1, 2}, we can establish a bijection between the set of balanced strings and T itself. A balanced string is defined as a string in which the sum of its digits is a multiple of 3.

We can define a function f: T" -> T that maps each string in T" to T by preserving the balanced property. If a string in T" is already balanced, f returns the string itself. If the string is not balanced, f replaces the last digit with digit that makes the sum a multiple of 3.

By showing that this function is both injective (one-to-one) and surjective (onto), we establish a bijection. The bijection rule states that if two sets have a bijection between them, they have the same cardinality. Therefore, the number of balanced strings is equal to the number of elements in T, which is 3.

Under a rotation about the origin of 180°

a point (x, y ) → (- x, - y ) , thus

(0, 5 ) → (0, - 5 )

(- 1, 1 ) → (1, - 1 )

(- 3, 2 ) → (3, - 2 )

(- 4, 4 ) → (4, - 4 )

3y = 3x + 15

The different values that could be be the greatest common divisor of the two integers are; 1, 2, 3, 4, 6

Let the numbers be a, b. Thus, the product of the GCD(a, b) and the LCM(a, b) will be ab.

Now, for us to get something to be a factor of the GCD we need to make it be a factor of both a, b. Thus, its' square must be a factor of 180.

Therefore, the only numbers whose square is a factor of 1800 are 1, 2, 3, 4, 6 and as such they are the only GCDs possible.

The perimeter of the window is 3.93 feet.

Perimeter is the total length of the sides of a two-dimensional shape.

perimeter = πr

Where, r is the radius of the circle

And, π = 3.14

According to the given question.

The window is in the shape of semicircle.

Radius of the window = \(\frac{2.5}{2} = 1.25 feet\)

Therefore, the perimeter of the window

= π × 1.25 ft

= 3.14 × 1.25

= 3.925

= 3.93 feet

Hence, the perimeter of the window is 3.93 feet.

The length of the other diagonal is 22.36 cm.

Diagonal is defined as a sloping line or the slant line, that connects to the vertices of a shape.

Let's call the length of the other diagonal "d".

Since a rhombus has perpendicular diagonals that bisect each other

we can use the Pythagorean theorem to find the length of the other diagonal:

d^2 = 10^2 + 10^2 = 100

d = sqrt(100) = 10 * sqrt(10) = 10 * 2.236 = 22.36 cm

Therefore, the length of the other diagonal is 22.36 cm.

in an election debate, two candidates for governor are debating about whether to raise the general sales tax from 5 to 7 percent, so candidate a assumes that the price effect would be larger than the quantity effect.

When a tax is added on a good or service at the point of sale and is financed by the client, it is known as general sales tax. The store is then obligated to transmit, or remit, the tax to the government.

Candidate a contends that revenue will rise along with the sales tax as it rises from 5 to 7 percent. This suggests that the price impact is greater than the quantity effect since, when the tax is raised, the price would rise and the quantity would fall. As a result, the tax revenue would only rise if the price effect is more than the quantity effect.

Additionally, Candidate b claims that the tax will harm consumers and merchants, slow the economy, and reduce tax revenue. However, this claim can only be supported if the quantity effect outweighs the price effect.

Candidate a assumes that the price effect would be larger than the quantity effect.

Step-by-step explanation:

Woozy Wheel: (-14, 1)

Roller Rail: (-2, -4)

\( \sqrt{ { - 14 - ( - 2))}^{2} + {(1 - ( - 4))}^{2} } \)

\( \sqrt{ {( - 12)}^{2} + {5}^{2} } \)

\( \sqrt{144 + 25} = \sqrt{169} = 13\)

The distance between the Woozy Wheel and the Roller Rail is D. 13 units

The distance formula between two points (x₁, y₁) and (x₂, y₂) is

D = \(\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\).

Given, A map of an amusement park is shown on the coordinate plane with the approximate location of several rides.

The point at which Woozy Wheel is (-14, 1) and the point at which Roller Rail

Step-by-step explanation:

oh dear me, what is the true original expression ?

13-7×135 ?

that would be 13 - 945 = -932

or

(13-7)×135 = 6×135 = 810

I guess, since this all does not fit with any of the answer options, you meant

a) The equation be \($$(3 x+y)^4$$\) then the binomial expression be \($$81 x^4+108 x^3 y+54 x^2 y^2+12 x y^3+y^4$$\).

b) The equation be \($$(x-2 y)^6$$\) then the binomial expression be\($$x^6-12 x^5 y+60 x^4 y^2-160 x^3 y^3+240 x^2 y^4-192 x y^5+64 y^6$$\)

The algebraic terms of the form (x + y)n are expanded using the binomial theorem. \((x + y)^n = ^nC_0 x_ny_0 +^ nC_1 x_{n-1}y_1,... + ^nC_{n-1} x_1y_{n-1} + ^nC_n x_0y_n\).

In this case, there are n + 1 terms in the binomial expansion with an exponent of n. In a progressive way, the second term's exponent is gradually rising while the first term's exponent in the expansion is steadily declining. The Pascals triangle or the combination formula

\(^nC_r\) = n! / [r! (n - r)!]! can be used to determine the coefficients of the binomial expansion.

a) Let the given equation be \($$(3 x+y)^4$$\)

Apply binomial theorem, we get

\($(a+b)^n=\sum_{i=0}^n\left(\begin{array}{l}n \\ i\end{array}\right) a^{(n-i)} b^i$\).

\($a=3 x, b=y$\)

\(=\sum_{i=0}^4\left(\begin{array}{l}4 \\i\end{array}\right)(3 x)^{(4-i)} y^i\)

simplifying the equation, we get

Simplifying the above equation, we get

\($\frac{4 !}{0 !(4-0) !}(3 x)^4 y^0= 81 x^4$\)

\($\frac{4 !}{1 !(4-1) !}(3 x)^3 y^1= 108 x^3 y$\)

\($\frac{4 !}{2 !(4-2) !}(3 x)^2 y^2=54 x^2 y^2$\)

\($\frac{4 !}{3 !(4-3) !}(3 x)^1 y^3= 12 x y^3$\)

\($$=81 x^4+108 x^3 y+54 x^2 y^2+12 x y^3+y^4$$\)

b) Let the given equation be \($$(x-2 y)^6$$\)

Apply binomial theorem: \($(a+b)^n=\sum_{i=0}^n\left(\begin{array}{l}n \\ i\end{array}\right) a^{(n-i)} b^i$\)

a = x, b = -2y

simplifying the equation, we get

\($$=\sum_{i=0}^6\left(\begin{array}{l}6 \\i\end{array}\right) x^{(6-i)}(-2 y)^i$$\)

1.386  is the sample variance .

What does the standard deviation of the sample mean?

Step 1:Add them up:

9.0 +  7.3 +  6.0 +  8.8 +  6.8 +  8.4 + 6.6  = 52.9

Step 2: Square your answer:

52.9 × 52.9 = 2798.41

…and divide by the number of items. We have 7 items in our example so:

2798.41 / 7 = 399.773

Set this number aside for a moment.

Step 3: Take your set of original numbers from Step 1, and square them individually this time:

9.0^2 +  7.3^2 +  6.0^2 +  8.8^2 +  6.8^2 +  8.4^2 + 6.6^2 = 408.09

Step 4: Subtract the amount in Step 2 from the amount in Step 3.

408.09 - 399.773 = 8.317

Set this number aside for a moment.

Step 5: Subtract 1 from the number of items in your data set. For our example:

7 – 1 = 6

Step 6: Divide the number in Step 4 by the number in.

The instantaneous rate of change of the function  is 2.

The instantaneous rate of change of a function at a particular point is the rate at which the function is changing at that point, or the slope of the tangent line to the graph of the function at that point. It gives an indication of how fast the function is increasing or decreasing at that point.

To compute the instantaneous rate of change of the function at x=a, we need to find the derivative of the function f(x) and evaluate it at x=a.

f(x) = 2x + 10

Taking the derivative of f(x) with respect to x:

f'(x) = 2

So, the instantaneous rate of change of f(x) at x=a is:

f'(a) = 2

Substituting a=3 in the above equation, we get:

f'(3) = 2

Therefore, the instantaneous rate of change of the function f(x) at x=3 is 2.

(L3) The orthocenter will lie in the exterior of a(n)  obtuse triangle. Contrary to an acute triangle, the orthocenter of an obtuse triangle will lie in the exterior of the triangle.

The orthocenter is the point of intersection of the altitudes of the triangle, which are perpendicular lines drawn from each vertex to the opposite side. In an obtuse triangle, one of the angles measures more than 90 degrees, so when an altitude is drawn from this vertex to the opposite side, it will lie outside of the triangle. Therefore, the three altitudes will intersect outside of the triangle, forming the orthocenter in the exterior. This is in contrast to an acute triangle, where all three altitudes intersect inside the triangle.
