x=y*10^z where 4 Find an expression for x^2 in standard form.
The expression for x² in standard form is x² = (yˣ×10)²= y²×10².
What is expression?Expression is a mathematics combination of symbol such as number and operators which produce the mathematical result and expression can involve a single trauma multiple term and usually consist of a combination of constant variables operators function.
This means that if x is given in the form of x = y×10, then x² can be expressed as y² × 10². This form is advantageous because it allows for easier manipulation of the numbers. For example, if x = 5 ×10², then x²can be expressed as (5×10²)²= 5²× 10²×²= 25 × 10⁴. This expression is much easier to understand than the expanded form of x² = 5²× 10² × 10² = 25 ×10².
In addition, this expression for x²allows for efficient calculation of larger powers of x. For example, if x = 5 ×10², then x²can be expressed as (5×10² = 5³ × 10²×³= 125 × 10⁶. This is much faster to calculate than the expanded form of x³= 5³ ×10² ×10²× 10² = 125 ×10⁶.
Therefore, the expression for x² in standard form is an effective way to manipulate and calculate larger powers of x.

Carnegie Learning.
The equation of the parallel lines is y = x + 2.
What are parallel lines?Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline. No matter how far we extend a parallel line, it will never meet another parallel line.
The slope of two parallel lines are equal.
The equation of the given line is:
y = x + 6
here, the slope of the line is 1.
So, the slope of the new line is 1.
The new line has the coordinates (-4, 1).
Using the point-slope form we have:
y - y1 = m (x - x1)
y - 1 = 1 (x + 1)
y - 1 = x + 1
y = x + 2
Hence, the equation of the parallel lines is y = x + 2.

The total cost for a meal of $110 plus a service charge of 18% is $129.8.
What is the total cost of the meal?Given that, the meal costs $110 plus a service charge of 18%.
Cost of meal = $110Service charge = 18%Cost of meal = ?The total cost of the meal will be the addition of cost of meal and the service charge.
Total cost = cost of meal + service charge

Triangle XYZ with vertices X(1,8), Y(8,7) and Z(7,-2): (x,y) -> (x-9,y-5)
Therefore, the new triangle XYZ with vertices X'(-8,3), Y'(-1,2) and Z'(-2,-7) is obtained after the transformation.
What exactly does a triangle mean?Triangles are called polygons if they have four quadrants or more. Its form is a simple geometric figure. When put together, the characters ABC create a right-angled triangle. When the boundaries are incompatible, Euclidean geometry generates a new rectangle with square corners. Triangles are regarded as polygons because they have three edges and three corners. Where a triangle's three edges intersect determines where its corners are. A triangle's interior sides add up to 180 degrees.
Here,
After the transformation, the new vertices of the triangle will be:
X(1-9, 8-5) = (-8,3)
Y(8-9, 7-5) = (-1,2)
Z(7-9, -2-5) = (-2,-7)

three married couples have bought 6 seats in the same row for a concert. in how many different ways can they be seated
The 3 couples can be seated in 20 ways.
Permutations CalculationsThe answer I provided uses the concept of permutations. In permutation, we calculate the number of arrangements or ways in which a set of elements can be arranged.
In this case, the question is asking for the number of ways in which 6 individuals (3 married couples) can be seated in a row. To find the number of arrangements, we can use the formula for permutations of multiples:
P(n, k) = n! / (n-k)!
Where n is the number of items to arrange and k is the number of identical items. In this case, n = 6 (number of individuals) and k = 3 (number of married couples).
However, we need to also account for the fact that within each married couple, the two individuals can be seated in either order. Hence, we need to divide the result by 2! for each couple, giving us the formula:
P(6, 3) / (2! * 2! * 2!) = 6! / (3! * 3!) = 20
So there are 20 different ways in which the 3 married couples can be seated in a row.

The value of the domain and the range of the composite function (gof)(x) as per f(x) = e^x and g(x) = x + 6 is equal to x∈ R⁺ ( real numbers ) and
x > 6 , x∈ R⁺ respectively.
Function f(x) is equal to e^x
Function g(x) = x + 6
Composite function (gof)(x) is equal to:
(gof)(x)

No, it is not possible to have a connected graph with six vertices of degrees 1, 1, 2, 2, 2, and 3.
As we know that the sum of the degrees of the vertices in a connected graph must be equal to twice the number of edges.
So, in this case, the sum of the degrees must be equal to 2 * K, where K is the number of edges in the graph.
Since the degrees of the vertices are 1, 1, 2, 2, 2, and 3,
the sum of the degrees is 1 + 1 + 2 + 2 + 2 + 3 = 11.
The number of edges must be K = 11 / 2 = 5.5,
which is not possible as the number of edges must be a positive integer.
