The vertex form of the quadratic equation is:

h(t) = -42*(x - 3)² + 378

And the maximum height is 378 ft.

We know that the height of the projectile is defined by the quadratic equation:

h(t) = -42t² + 252t

Remember that for any quadratic equation:

y = a*x² + b*x + c

The vertex is at:

x = -b/2a

So in this case, the vertex is at:

t = -252/(2*-42)

t = 3

So the maximum height of the projectile is:

h(3) = -42*3² + 252*3 = 378

And thus, the vertex is (3, 378), then the vertex form is:

To verify equivalent expressions, you need to evaluate the expressions for different values of x and compare the results. For the given list of x values (0, 1, 2), you can plug them into the two equations one at a time and compare the results.

For x=0:

Equation 1: 0

Equation 2: 0

For x=1:

Equation 1: 1

Equation 2: 1

For x=2:

Equation 1: 4

Equation 2: 8

Since the results of the equations do not match for x=2, the expressions are not equivalent.

To verify equivalent expressions, you can plug in the given values of x into the equations and see if they produce the same result. Here are the steps to do this:

1. Take the first equation and plug in the value of x. For example, if the equation is y = 2x + 1 and x = 0, then y = 2(0) + 1 = 1.

2. Do the same for the second equation with the same value of x. For example, if the second equation is y = x + 1 and x = 0, then y = 0 + 1 = 1.

3. Compare the results of the two equations. If they are the same, then the expressions are equivalent for that value of x.

4. Repeat these steps for the other values of x (1 and 2) and fill out the rest of the table with the results.

5. If the expressions produce the same result for all values of x, then they are equivalent expressions.

Answer: We can use the formula for the price elasticity of demand to solve this problem:

Price elasticity of demand = percent change in quantity demanded / percent change in price

We are given that the price of chicken breast rises from $3.00 to $3.60 per pound, which is a 20% increase:

percent change in price = (3.60 - 3.00) / 3.00 = 0.20 = 20%

We are also given that the demand for chicken breast falls by 25%, which is a 25% decrease:

percent change in quantity demanded = -25%

Using these values in the formula, we get:

Price elasticity of demand = (-25%) / (20%) = -1.25

Since we are interested in the absolute value of the price elasticity of demand, we have:

|Price elasticity of demand| = |-1.25| = 1.25

A price elasticity of demand greater than 1 is considered elastic, and a price elasticity of demand less than 1 is considered inelastic. Therefore, the answer is (d) 1.25; elastic.

15) The set is a basis for R² because it is linearly independent and spans R². 16) The set is not a basis for R² because it is linearly dependent. 17) The set is a basis for R³ because it is linearly independent and spans R³. 18) The set is a basis for R³ because it is linearly independent and spans R³.

Exercise 15:

To determine if the set {[5,-2],[10,-3]} is a basis for R², we need to check if the set is linearly independent and spans R².

To check for linear independence, we set the linear combination of the vectors to zero and solve for the coefficients:

c₁[5,-2] + c₂[10,-3] = [0,0]

This leads to the system of linear equations:

5c₁ + 10c₂ = 0

-2c₁ - 3c₂ = 0

Solving for c₁ and c₂ gives us c₁ = 0 and c₂ = 0, which means that the set is linearly independent.

To check for spanning, we need to determine if any vector in R² can be expressed as a linear combination of {[5,-2],[10,-3]}. Let [x,y] be an arbitrary vector in R². We can solve for c₁ and c₂ in the equation c₁[5,-2] + c₂[10,-3] = [x,y] to get c₁ = (3y - 2x)/(-20) and c₂ = (x - 5y)/(-20). Since we were able to express any vector in R² as a linear combination of {[5,-2],[10,-3]}, the set {[5,-2],[10,-3]} is a basis for R².

Exercise 16:

To determine if the set {[-4,6],[2,-3]} is a basis for R², we again need to check for linear independence and spanning.

Setting the linear combination of the vectors to zero and solving for the coefficients gives:

c₁[-4,6] + c₂[2,-3] = [0,0]

which leads to the system of linear equations:

-4c₁ + 2c₂ = 0

6c₁ - 3c₂ = 0

Solving for c₁ and c₂ gives us c₁ = c₂ = 0, which means that the set is linearly independent.

To check for spanning, we again need to determine if any vector in R² can be expressed as a linear combination of {[-4,6],[2,-3]}. Let [x,y] be an arbitrary vector in R². Solving for c₁ and c₂ in the equation c₁[-4,6] + c₂[2,-3] = [x,y] gives us c₁ = (-3y + 2x)/(-20) and c₂ = (6y - 4x)/(-20). However, we notice that the determinant of the matrix formed by the two vectors is zero, which means that the vectors are linearly dependent and cannot form a basis for R².

Exercise 17:

To determine if the set {[0,1,-2],[5,-7,4],[6,3,5]} is a basis for R³, we need to check for linear independence and spanning.

Setting the linear combination of the vectors to zero and solving for the coefficients gives:

c₁[0,1,-2] + c₂[5,-7,4] + c₃[6,3,5] = [0,0,0]

which leads to the system of linear equations:

5c₂ + 6c₃ = 0

c₁ - 7c₂ + 3c₃ = 0

-2c₁ + 4c₂ + 5c₃ = 0

Solving for c₁, c₂, and c₃ gives us c₁ = c₂ = c₃ = 0, which means that the set is linearly independent.

To check for spanning, we need to determine if any vector in R³ can be expressed as a linear combination of {[0,1,-2],[5,-7,4],[6,3,5]}. Let [x,y,z] be an arbitrary vector in R³. We can solve for c₁, c₂, and c₃ in the equation c₁[0,1,-2] + c₂[5,-7,4] + c₃[6,3,5] = [x,y,z] to get c₁ = (-5y - 6z)/(-47), c₂ = (-2x - 3z)/(-47), and c₃ = (x + y)/47. Since we were able to express any vector in R³ as a linear combination of {[0,1,-2],[5,-7,4],[6,3,5]}, the set {[0,1,-2],[5,-7,4],[6,3,5]} is a basis for R³.

Exercise 18:

To determine if the set {[1,1,-2],[-5,-1,2],[7,0,-5]} is a basis for R³, we need to check for linear independence and spanning.

Setting the linear combination of the vectors to zero and solving for the coefficients gives:

c₁[1,1,-2] + c₂[-5,-1,2] + c₃[7,0,-5] = [0,0,0]

which leads to the system of linear equations:

c₁ - 5c₂ + 7c₃ = 0

c₁ - c₂ = 0

-2c₁ + 2c₂ - 5c₃ = 0

Solving for c₁, c₂, and c₃ gives us c₁ = c₂ = c₃ = 0, which means that the set is linearly independent.

To check for spanning, we need to determine if any vector in R³ can be expressed as a linear combination of {[1,1,-2],[-5,-1,2],[7,0,-5]}. Let [x,y,z] be an arbitrary vector in R³. We can solve for c₁, c₂, and c₃ in the equation c₁[1,1,-2] + c₂[-5,-1,2] + c₃[7,0,-5] = [x,y,z] to get c₁ = (y - 7z - 1)/(-10), c₂ = (-x + z + 1)/10, and c₃ = (2x - 2y + 5z)/10. Since we were able to express any vector in R³ as a linear combination of {[1,1,-2],[-5,-1,2],[7,0,-5]}, the set {[1,1,-2],[-5,-1,2],[7,0,-5]} is a basis for R³.

Step-by-step explanation:

You want to know if a quadrilateral can be rotated so that each side is parallel to the corresponding side of its image.

In general, a line segment's image will be parallel to the original if it is rotated 180°. Hence the line segments that make up a quadrilateral's image will be parallel to corresponding sides if the quadrilateral is rotated 180°.

The attachment shows a quadrilateral rotated 180°.

Additional comment

We assume that the "corresponding side" of AB is A'B' in the image.

If square ABCD is rotated 90°, then side AB will be parallel to side B'C', and the same will be true for 3 other pairs of sides. For the purpose of this question, we don't consider AB and B'C' to be "corresponding" sides.
