You have studied polynomials consisting of constants and/or variables combined by addition or subtraction. The variables may include exponents. The examples so far have been limited to expressions such as 5x4 + 3x3 – 6x2 + 2x containing one variable, but polynomials can also contain multiple variables. An example of a polynomial with two variables is 4x2y – 2xy2 + x – 7.
Many formulas are polynomials with more than one variable, such as the formula for the surface area of a rectangular prism: 2ab + 2bc + 2ac, where a, b, and c are the lengths of the three sides. By substituting in the values of the lengths, you can determine the value of the surface area. By applying the same principles for polynomials with one variable, you can evaluate or combine like terms in polynomials with more than one variable.
The product of (7x²y³) and (3x⁵y⁸) is obtained by multiplying the coefficients and adding the exponents of like terms, resulting in c) 21x⁷y¹¹.
To find the product of the two algebraic expressions (7x²y³) and (3x⁵y⁸), we simply multiply the coefficients and add the exponents of corresponding variables:
Multiply the coefficients: 7 * 3 = 21
Add the exponents of x: x² * x⁵ = x²⁺⁵ = x⁷
Add the exponents of y: y³ * y⁸ = y³⁺⁸ = y¹¹
Therefore, the product is 21x⁷y¹¹, which corresponds to option (c).

To solve the equation 3x−2=4x−1 , Veronica graphs the functions f(x)=3x−2 and g(x)=4x−1
on the same set of coordinate axes.
Which statement describes the solution of the equation 3x−2=4x−1?
(A) The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.
(B) The solution of the equation cannot be found graphically. Veronica should solve the equation algebraically.
(C) The solution of the equation is the y-coordinate of the ordered pair where the graphs of the two functions intersect.
(D) The solution of the equation is the y-intercept of the linear equations.
we have that
f(x)=3x-2
g(x)=4x-1
3x-2=4x-1-------------> 4x-3x=-2+1--- > x=-1
find the value of f(x) or g(x) for x=-1
f(x)=3x-2 -------> f(-1)=3*(-1)-2 ------> f(-1)=-5
the solution is the point (-1,-5)
using a graph tool
see the attached figure
the answer is
case (A) The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.Moving a figure around a fixed point in the plane is called making a ___.
Answer:
Rotation.
Step-by-step explanation:
There are three rigid motions (which do not change the shape and size of the figures): rotation, translation and reflection.
You make a rotation of a figure when you turn it about a fixed point (which can be inside, on an edge or outside the figure) and it is measured in degrees. The rotation can be clockwise or counterclockwise.
Answer:
The answer is Reflection
Find an equation for the circle that has center (−1, 4) and passes through the point (3, −5).
The correct answer for the equation of the circle with center (-1,4) and passes through point (3,-5) is [tex](x+1)^2 + (y-4)^2 = 97[/tex].
Given Co-ordinates:
Centre:
(-1,4)
Point of intersection:
(3,-5)
The standard equation of circle with center (h, k) is:
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
(h, k) are co-ordinates of center
Given in question:
h= -1
k = 4
Find radius of the circle:
distance between the center(-1,4) and the given point (3, -5).
[tex]r = [\sqrt{(x_{2}- x_{1})^2 + (y_{2}- y_{1})^2 }[/tex]
[tex]r = [\sqrt{((3- (-1))^2 + (-5-4)^2 }[/tex]
[tex]= \sqrt{(4)^2 + (-9)^2 }[/tex]
[tex]= \sqrt{16 + 81}[/tex]
[tex]= \sqrt{97}[/tex]
Now, Equation of circle:

[tex](x+1)^2 + (y-4)^2 = 97[/tex]
The equation of circle is [tex](x+1)^2 + (y-4)^2 = 97[/tex].

The equation of the circle with center (-1, 4) and passing through the point (3, -5) is (x + 1)² + (y - 4)² = 97.
Explanation:The subject of this question is geometry, specifically about the equations of circles. We start by noting that the general equation of a circle is (x-h)² + (y-k)² = r², where (h, k) are the coordinates of the circle's center and r is the radius of the circle.
Here, the center of the circle is at (-1, 4). We don't know the radius yet, but we know that the circle passes through the point (3, -5). The radius is the distance from the center of the circle to any point on the circle. We can find this using the distance formula which is d = sqrt[(x₂ - x₁)² + (y₂ - y₁)²].
Substituting the given points into the distance formula, we get: r = sqrt[(3 - (-1))² + (-5 - 4)²] which simplifies to r = sqrt[(4)² + (-9)²] = sqrt[16 + 81] = sqrt[97].
Now we can write the equation of the circle, substituting the center and radius values into the equation. This gives us: (x - (-1))² + (y - 4)² = sqrt[97]² which simplifies to (x + 1)² + (y - 4)² = 97.

A sample has a mean of m = 90. if each score in the sample is multiplied by 5, then what is the mean for the new distribution?
Final answer:
When each score in a sample is multiplied by a constant, the mean of the new distribution will also be multiplied by that constant, resulting in a new mean value of 450.
Explanation:
The mean of a sample is a measure of the average value of the data points in that sample.
When each score in a sample is multiplied by a constant, like 5 in this case, the resulting mean of the new distribution will also be multiplied by that constant.
In this scenario, since each score is multiplied by 5, the mean of the new distribution will be 5 times the original mean, giving a new mean of 450.

What is the sum of a 6-term geometric series if the first term is 23 and the last term is 1,358,127? 1,395,030 1,461,460 1,527,890?
Answer:
Last term is 1,527,890.
Step-by-step explanation:
In this question a geometric series has been given with
first term A = 23
6th term = 1,358,127
Number of terms n = 6
we have to calculate the sum of this geometric series
we know [tex]T_{n}=a(r)^{n-1}[/tex]
[tex]T_{6}=23.(r)^{6-1}=1358,127[/tex]
[tex]r^{5}=\frac{1358127}{23}=59049[/tex]
[tex]r = 59049^{\frac{1}{5} }[/tex]
r = 9
Now we know the formula to sum a geometric series is
[tex]S=a.\frac{r^{n-1} }{r-1}[/tex]
S = 23 × [tex]\frac{(9^{6-1)} }{(9-1)}[/tex]
S = 23 × [tex]\frac{(531441-1)}{8}[/tex]
S = [tex]\frac{23.(531440)}{8}[/tex] = 23 × 66430
S = 1,527,890
