select the correct product (x2+3)(x3-5)
The question involves multiplying two polynomials, (x^2+3) and (x^3-5), using the distributive property to find the product x^5 - 5x^2 + 3x^3 - 15.
The question asks for the product of the polynomials (x2+3) and (x3-5). To find the product, each term in the first polynomial is multiplied by each term in the second polynomial. This is known as the distributive property or the FOIL method when dealing with binomials. Therefore, the product is:
x^5 - 5x^2 + 3x^3 - 15.
To summarize the multiplication process:
Multiply x2 by x3 to get x5
Multiply x2 by -5 to get -5x2
Multiply 3 by x3 to get 3x3
Multiply 3 by -5 to get -15
Hence, This is the standard process for multiplying polynomials.
Solve the inequalities by graphing. Select the correct graph. y > x y < -x
The solution to the system of inequalities y > x and y < -x is a V-shaped region in the second and fourth quadrants of the coordinate plane.
Graph attached.
To solve the system of inequalities graphically, you need to shade the regions on the coordinate plane that satisfy both inequalities.
The first inequality is y > x. This means that all points above the line y = x satisfy this inequality.
The second inequality is y < -x. This means that all points below the line y = -x satisfy this inequality.
Now, let's graph both lines and shade the regions that satisfy both inequalities:
Graph the line y = x. This is a straight line with a slope of 1 that passes through the origin (0,0) and goes up and to the right.
Graph the line y = -x. This is also a straight line with a slope of -1 that passes through the origin (0,0) and goes down and to the right.
Graph attached.
The shaded region that satisfies both inequalities is the area between these two lines, below y = -x, and above y = x.
It forms a V-shaped region in the second and fourth quadrants of the coordinate plane.
Therefore, the correct graph should show the shaded V-shaped region that represents the solution to the system of inequalities.

how to do midpoint and distance formula
Final answer:
The midpoint formula calculates the center point between two points on a coordinate plane, while the distance formula calculates the distance between two points using the Pythagorean theorem.
Explanation:
Understanding the Midpoint and Distance Formulas
The midpoint formula is used to find the exact center point between two defined points on a coordinate plane. To find the midpoint (M) between two points, (X1, Y1) and (X2, Y2), you use the formula:
M = ((X1 + X2) / 2, (Y1 + Y2) / 2)
For example, to find the midpoint between the points (2, 3) and (4, 8), you would calculate:
M = ((2 + 4) / 2, (3 + 8) / 2) = (3, 5.5)
The midpoint between these points is at coordinates (3, 5.5).
The distance formula, on the other hand, is used to determine the distance between two points on a coordinate plane.
The formula is derived from the Pythagorean theorem and is written as:
D = \(√((X2 - X1)^2 + (Y2 - Y1)^2)\)
Using the above points, the distance (D) would be:
D = \(√((4 - 2)^2 + (8 - 3)^2)√ = \(√(4+25) = \(√29\)√
The distance between the two points is the square root of 29.
Practicing these formulas enhances your problem-solving skills and helps in many areas of mathematics, including geometry and algebra.

Explain how to write an equivalent expression using the distributive property. 2(11 + y)
Final answer:
To write an equivalent expression using the distributive property for the expression 2(11 + y), distribute 2 to both terms inside the parentheses and simplify.
Explanation:
To write an equivalent expression using the distributive property for the expression 2(11 + y), we can distribute the 2 to both terms inside the parentheses.
This gives us:
2 * 11 + 2 * y = 22 + 2y
So, the equivalent expression using the distributive property is 22 + 2y.

What is the least common denominator of the equation 2/9x+2/3x=7
Suppose you are climbing a hill whose shape is given by the equation z = 1400 − 0.005x2 − 0.01y2, where x, y, and z are measured in meters, and you are standing at a point with coordinates (100, 120, 1206). the positive x-axis points east and the positive y-axis points north. (a) if you walk due south, will you start to ascend or descend?
If walking due south from the point (100, 120, 1206) will cause you to descend, as the slope of the hill in the southward direction is negative.
To determine whether you will ascend or descend when walking due south from the point (100, 120, 1206), we need to consider the slope of the hill in the southward direction, which corresponds to the negative y-direction.
Given the equation of the hill's shape: [tex]\[ z = 1400 - 0.005x^2 - 0.01y^2 \][/tex]
We can find the slope in the y-direction (southward) by taking the partial derivative of z with respect to y:
[tex]\[ \frac{\partial z}{\partial y} = -2 \cdot 0.01 \cdot y \][/tex]
Evaluating this derivative at the point (100, 120, 1206) gives us the slope in the y-direction at that point:
[tex]\[ \frac{\partial z}{\partial y}\Bigg|_{(100, 120, 1206)} = -2 \cdot 0.01 \cdot 120 = -2.4 \][/tex]
Since the slope is negative, this means that as you move in the positive y-direction (northward), the height z decreases. Conversely, moving in the negative y-direction (southward) will also result in a decrease in height z, because the slope is linear and does not change direction.
Therefore, walking due south from the point (100, 120, 1206) will cause you to descend, as the slope of the hill in the southward direction is negative.

pete's pools installs rectangular pools that are all 10 feet wide. the length can vary from 10 feet to 30 feet. the company installed a pool with a perimeter of 76 feet. what was the length of the pool ?
The length of pool is 28 feet.
What is perimeter?The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.
Given rectangular pool
width of pool is 10 feet,
and length is between 10 to 30 feet
perimeter of pool = 76 feet
perimeter = p = 2(l + b)
where l = length and b = breadth/width
76 = 2(l + 10)
l + 10 = 38
l = 38 - 10
l = 28 feet
Hence length of pool is 28 feet.

Which inequalities have no solution? Check all of the boxes that apply.
A. x > x
B. –3x mr001-1.jpg –3x
C. –4 + x > –2 + x
D. x – 2 < x + 3
Answer: The answer is (A) and (C).
Step-by-step explanation: We are given four options and we are to check which of these inequalities have no solution.
(A) We have
[tex]x>x\\\\\Rightarrow x-x>0\\\\\Rightarrow 0>1,[/tex]
which cannot be possible, so this inequality will have no solution.
(B) We have
[tex]-3x=-3x\\\\\Rightarrow -3x+3x=0\\\\\Rightarrow 0=0,[/tex]
which is always true, so this equation will have infinitely many solutions.
(C) We have
[tex]-4+x>-2+x\\\\\Rightarrow -4+x+2-x>0\\\\\Rightarrow -2>0,[/tex]
which is never true, so this inequality will have no solution.
(D) We have
[tex]x-2<x+3\\\\\Rightarrow x-2-x-3<0\\\\\Rightarrow -5<0,[/tex]
which is always true, so this inequality will have infinitely many solutions.
Thus, the correct options are (A) and (C).

A hypothesis test has a significance level of 10%. Explain what this significance level represents.
Answer:
A significance level of 10% i.e.0.10 represents the chance of rejecting the null hypothesis
Step-by-step explanation:
Given :A hypothesis test has a significance level of 10%.
To Find :Explain what this significance level represents.
Solution :
Definition : The significance level is the probability of rejecting the null hypothesis when it is true.
So, significance level = 10%.
This means there is a 0.10 chance of rejecting the null hypothesis
Hence a significance level of 10% i.e.0.10 represents the chance of rejecting the null hypothesis
