Answer:

  f(x) = x² +2

Step-by-step explanation:

x-values are evenly spaced, and y-values decrease to a minimum of 2, then increase again. First differences are -1, 1, 3, 5, and second differences are constant at 2. This means that a 2nd degree polynomial can be used for the rule.

The minimum of f(x) occurs at x=0, so there is no horizontal shift of the vertex of the quadratic function. f(1) -f(0) = 1, so the vertical scale factor for the quadratic is 1.

The quadratic with a vertex of (0, 2) and a vertical scale factor of 1 is ...

  f(x) = 1·(x -0)² +2

  f(x) = x² +2 . . . . . . simplified

Comment on differences

"First differences" are the differences between successive "y" values when the "x" values are evenly spaced. Here, they are 2-3 = -1, 3-2 = 1, 6-3 = 3, 11-6 = 5. These are not constant, so the function is not a linear function.

"Second differences" are the differences between successive first differences. Here, they are 1-(-1) = 2, 3-1 = 2, 5-3 = 2. These are constant, so the function is a quadratic (2nd-degree). When n-th differences are constant, the sequence can be modeled by a polynomial of degree n.

__

Comment on determining the rule

Once you know the rule is 2nd-degree, there are a number of ways you can find out what it is. One way is to write it as ...

  f(x) = ax^2 + bx + c

and fill in three different values for x and f(x). This will give you three linear equations in a, b, and c, which can be solved by any of the usual means for solving systems of linear equations.

Fortunately, this set of data includes the vertex of the function, making it easy to start with the vertex form:

  f(x) = a(x -h)^2 +k

where (h, k) is the vertex (minimum, in this case), and "a" is the vertical scale factor. The value of "a" is easily determined as being the difference between f(h+1) and f(h). Here, h=0, so that is f(1) -f(0) = 3-2 = 1.

Answer:

x² +2

Step-by-step explanation:

To find the product of (7x + 3y)(8x + 5y), you can use the distributive property of multiplication. The equivalent expression is 56x^2 + 59xy + 15y^2.

To find the product of (7x + 3y)(8x + 5y), you can use the distributive property of multiplication over addition.

This means that each term in the first expression is multiplied by each term in the second expression.

Here are the steps:

Apply the distributive property to multiply 7x by each term in the second expression: 7x * 8x + 7x * 5y

Apply the distributive property to multiply 3y by each term in the second expression: 3y * 8x + 3y * 5y

Simplify each term: 56x^2 + 35xy + 24xy + 15y^2

Combine like terms: 56x^2 + 59xy + 15y^2

Therefore, the expression (7x + 3y)(8x + 5y) is equivalent to 56x^2 + 59xy + 15y^2.

Step-by-step explanation:

Final answer:

The volume of the refrigerator is factored by dividing with the given height, resulting in a quadratic polynomial that provides the other two dimensions. Upon factoring, we discover that the other dimensions are x - 6 and x + 1, corresponding to option D.

Explanation:

The volume of the refrigerator is given by the polynomial [tex]x^3 - 3x^2 - 16x - 12[/tex]. To find the other two dimensions of the refrigerator, we need to factor this polynomial using the given height of the refrigerator, which is x + 2. The goal is to divide the volume polynomial by the height polynomial to get the product of the remaining two dimensions.

We proceed with polynomial division or factoring:

Divide the volume polynomial by x + 2 using synthetic division or long division.

The result should be a quadratic polynomial that further factors into the product of two linear factors corresponding to the unknown dimensions.

Factor the quadratic polynomial to find the two missing dimensions.

In this case, the volume polynomial [tex]x^3 - 3x^2 - 16x - 12[/tex] can be divided by x + 2 to yield [tex]x^2 - 5x - 6[/tex], which can then be factored into (x - 6)(x + 1). Hence, the other two dimensions are x - 6 and x + 1, making option D correct.

The set of integers 27, 32, 45 is NOT a Pythagorean triple and are NOT the side lengths of a right triangle ⇒ D

Step-by-step explanation:

The Pythagorean triple is:

A. 12, 16, 20

∵ 20 is the greatest number

∵ (12)² + (16)² = 144 + 256 = 400

∵ (20)² = 400

∴ (20)² = (12)² + (16)²

∴ The set of integers 12, 16, 20 is a Pythagorean triple

∴ 12, 16, 20 are the side lengths of a right triangle

B. 10, 24, 26

∵ 26 is the greatest number

∵ (10)² + (24)² = 100 + 576 = 676

∵ (26)² = 676

∴ (26)² = (10)² + (24)²

∴ The set of integers 10, 24, 26 is a Pythagorean triple

∴ 10, 24, 26 are the side lengths of a right triangle

C. 14, 48, 50

∵ 50 is the greatest number

∵ (14)² + (48)² = 196 + 2304 = 2500

∵ (50)² = 2500

∴ (50)² = (14)² + (48)²

∴ The set of integers 14, 48, 50 is a Pythagorean triple

∴ 14, 48, 50 are the side lengths of a right triangle

D. 27, 32, 45

∵ 45 is the greatest number

∵ (27)² + (32)² = 729 + 1024 = 1753

∵ (45)² = 2025

∴ (45)² ≠ (27)² + (32)²

∴ The set of integers 27, 32, 45 is NOT a Pythagorean triple

∴ 27, 32, 45 are NOT the side lengths of a right triangle

The set of integers 27, 32, 45 is NOT a Pythagorean triple and are NOT the side lengths of a right triangle

45 gallons of water used per person each month

Solution:

Given that,

The town of new London uses about 2,750,000 gallons of water each month

The population of new London is approximately 61,000

To find: Number of gallons of water used per person each month

From given,

Total gallons of water each month = 2750000

Population = 61000

Therefore,

[tex]Gallons\ of\ water\ per\ person = \frac{\text{Total gallons of water each month}}{population}[/tex]

[tex]Gallons\ of\ water\ per\ person = \frac{2750000}{61000}\\\\Gallons\ of\ water\ per\ person = \frac{2750}{61}\\\\Gallons\ of\ water\ per\ person =45.08 \approx 45[/tex]

Final answer:

To simplify the expression 24 - 4.57 + (-4.62), add the negative numbers together and then subtract the sum from the positive number, resulting in a simplified answer of 14.81.

Explanation:

The question involves simplifying an expression, which is a basic arithmetic operation in mathematics. We are given the expression 24 - 4.57 + (-4.62). To simplify, we need to combine like terms and perform the addition and subtraction.

First, let's combine the positive and negative numbers separately:

Positive number: 24

Negative numbers: -4.57 and -4.62

We add the negative numbers together: -4.57 + (-4.62) = -9.19

Now, we subtract this sum from the positive number:

24 - 9.19 = 14.81

Therefore, the simplified result of the expression 24 - 4.57 + (-4.62) is 14.81.

Answer:

(2,-5)

Step-by-step explanation:

P(2,5)

(x,y)

Reflection over x-axis so the x coordinate stays the same while the y coordinate changes from a positive to a negative.

The point P(2, 5) reflected over the x-axis will have coordinates (2, -5), as the x-coordinate remains unchanged and the y-coordinate becomes negative.

When the point P(2, 5) is reflected over the x-axis, the x-coordinate remains the same while the y-coordinate changes sign. Therefore, the coordinates of the resulting point, P', after reflection would be (2, -5). This is because reflecting over the x-axis means that we keep the horizontal position of the point the same (same x-coordinate), but flip the vertical position (change the sign of the y-coordinate).

Step-by-step explanation:

Let's find the first, fourth and tenth terms of the arithmetic sequence described by the given rule:

A(n) = 5 + (n-1) (1/6)

First term:

A(1) = 5 + (1-1) (1/6)

A(1) = 5 + (0) (1/6)

A(1) = 5

Fourth term:

A(4) = 5 + (4-1) (1/6)

A(4) = 5 + (3) (1/6)

A(4) = 5 + 3/6 = 5 3/6 = 5 1/2 (simplifying)

Tenth term:

A(10) = 5 + (10-1) (1/6)
