A homeowner collects data about the amount of oil , in gallons, used to heat the house per month for 5 months and the average monthly temperature , in degrees Fahrenheit, for those months. The scatter plot shows the data

The CLOSEST to the curve of best fit for the data shown is:

(c). y = -8x^2 - 0.5x + 9

The line of best fit is defined as a straight line that is drawn to pass through a set of plotted data points that produces the best and most approximate relationship between such given data points.

From the given graph, we see that:

at x = 1, y = 0

Thus:

a) -10x² - 0.5x + 8

Plugging x = 1:

-10(1)² - 0.5(1) + 8

= -10 - 0.5 + 8 = -2.5

b) y = -2x² + 0.2x + 23

At x = 1:

y = -2(1)² + 0.2(1) + 23

y = 21.2

c) y = -8x² - 0.5x + 9

At x = 1:

y = -8(1)² - 0.5(1) + 9

y = -8 - 0.5 + 9

y = 0.5

d)  y = -5x² - 18x + 66

At x = 1:

The first four terms of the sequence a(n) = 3n + 2 when evaluated are 5, 8, 11 and 14

A sequence can be arithmetic or geometric or neither

The definition of the function is given as

a(n) = 3n + 2

The above definitions imply that we simply add 2 to the previous term to get the current term

So, we have

a(1) = 3 * 1 + 2

a(1) = 5

Next. we have

a(2) = 3 * 2 + 2

a(2) = 8

Also, we have

a(3) = 3 * 3 + 2

a(3) = 11

Lastly, we have

a(4) = 3 * 4 + 2

Evaluate the equation

a(4) = 14

Hence, the first four terms are 5, 8, 11 and 14

Answer:

  x = 8

Step-by-step explanation:

You want to know the value of x in this similar triangle geometry.

When a segment is drawn in a triangle parallel to the base, it divides the sides proportionally. Every segment on the left has the same ratio to the corresponding segment on the right:

  x/6 = 4/3

This equation is solved in the usual way. Multiply by the inverse of the coefficient of x:

  6(x/6) = 6(4/3)

  x = 8

__

Additional comment

Every proportion can be written several ways. Another way to write this one is ...

  x/4 = 6/3

  x = 4(2) = 8 . . . . . multiply by 4

If you need to, you can prove the triangles are similar by considering corresponding angles. ∠A≅∠A, ∠APW≅∠AVZ, so the triangles are similar by the AA postulate. (Corresponding angles where a transversal crosses parallel lines are congruent.)

Perhaps not so obvious is the relationship between segments of the long side and segments of the short side. The similarity relation tells us ...

  AV/AP = AZ/AW

  (4+x)/x = (3+6)/6

  4/x +1 = 3/6 +1 . . . . . do the division

  4/x = 3/6 . . . . . . . . subtract 1

  x/4 = 6/3 . . . . . . invert both sides . . . compare to above

In conclusion, we need to identify the set of values of x for which either f(x)=-1/4 or f(-x)=-1/4 in order to solve to the equation f(|x|)=-1/4.

The expression f(|x|)=-1/4 indicates that the absolute value of x's function f is equal to 1/4. Any x values that satisfy this equation are what we are trying to find. We can rewrite the equation as f(x)=-1/4 when x is positive and f(-x)=-1/4 when x is negative because the absolute value of x is always positive.

We must search for values of x such that f(x)=-1/4 or f(-x)=-1/4 in order to identify the answers. Without knowing more about the function, f may be anything, hence we cannot know the precise solutions.

Therefore, we can state that x or -x is a solution to the equation if there is a value of x such that f(x)=-1/4 or f(-x)=-1/4.

As a result, we must identify the range of x values for which either f(x) or f(-x) = 1/4.

a. The possible zeros of the polynomial function are ±1, ±2, ±5, ±10, ±25, ±50

b. x = -1 is a zero of f(x)

c. The remaining zeros of the polynomial function is -1, (3 + i√103) / 2, (3 - i√103) / 2

To find all possible zeros of the polynomial function f(x), we can use the Rational Root Theorem, which states that if a polynomial function with integer coefficients has a rational zero of the form p/q, where p and q are integers and q ≠ 0, then p must be a factor of the constant term and q must be a factor of the leading coefficient.

The constant term of f(x) is 50, which has the factors ±1, ±2, ±5, ±10, ±25, ±50. The leading coefficient of f(x) is 1, which has the factors ±1. So the possible rational zeros of f(x) are:

±1, ±2, ±5, ±10, ±25, ±50

b. We can use synthetic division to test each of the possible rational zeros and find an actual zero. Let's start by testing x = 1:

  | 1  -2  -25  50

1  |    1   -1  -26  24

  |______________

  1  -1  -26  24

The remainder is 24, which means that x = 1 is not a zero of f(x).

Let's try x = -1:

  | 1  -2  -25  50

-1 | 1 -3 28 -78

|______________

1 -3 28 -78

The remainder is -78, which means that x = -1 is a zero of f(x).

c. We can use the quotient from part (b), which is x^2 - 3x + 28, to find the remaining zeros of the polynomial function f(x). To do this, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

where a = 1, b = -3, and c = 28. Plugging in these values, we get:

x = (3 ± √(-103)) / 2

Since the discriminant is negative, there are no real solutions. However, there are two complex solutions:

x = (3 ± i√103) / 2

So the zeros of f(x) are:

x = -1, (3 + i√103) / 2, (3 - i√103) / 2

Therefore, 150 is the largest integer that is a factor of both 1450 and 2400.

Prime factorization is the process of breaking down a positive integer into its prime factors, which are prime numbers that can divide the integer without a remainder. Every positive integer can be written as a product of prime numbers in a unique way, called its prime factorization.  Prime factorization is important in many mathematical applications, such as finding the greatest common divisor and least common multiple of two or more integers, simplifying fractions, and solving problems related to divisibility, prime numbers, and modular arithmetic.

Here,

To find the largest integer that is a factor of both 1450 and 2400, we need to first express both numbers in terms of their common prime factors and then find the product of the common prime factors raised to their lowest exponent.

The prime factorization of 1450 is 2 × 5² × 29.

The prime factorization of 2400 is 2⁴ × 3 × 5².

To find the common factors of these two numbers, we need to look for the prime factors that appear in both factorizations. These common prime factors are 2, 5², and 3.

ii. The points of intesection of the common chords of the curve x² + y² = 4 and x² - 4y + 1 = 0 are

The common chords of circles are the chords that pass through the points of intersection of the curves.

i. Given the curve x² + y² = 4 and y² = 3x. We desire to find their points of intesection of the common chords. We proceeds as follows.

Since  x² + y² = 4 and y² = 3x. Substituting the second equation into the first, we have

x² + y² = 4 and y² = 3x.

x² + 3x = 4

Re-arranging, we have

x² + 3x - 4 = 0

Factorizing the quadratic equation, we have

x² - x + 4x - 4 = 0

x(x - 1) + 4(x - 1) = 0

(x + 4)(x - 1) = 0

⇒ x + 4 = 0 and x - 1 = 0

⇒ x = - 4 and x = 1

Now, y² = 3x.

⇒ y = ±√3x

So.substituting x = -4 into the equation, we have

y = ±√3x

y = ±√(3 × -4)

= ±√(-12)

Since the square root is negative, this answer is invalid.

Substituting x = 1 into y, we have

y = ±√3x

y = ±√3(1)

y = ±√3

So, the points of intersection are (1, √3) and (1,-√3)

ii. Given the curve x² + y² = 4 and x² - 4y + 1 = 0. We desire to find their points of intesection of the common chords. We proceeds as follows.

Since  x² + y² = 4 and x² - 4y + 1 = 0. From the second equation, we have

x² = 4y - 1

Substituting this equation into the first, we have

x² + y² = 4 and x² = 4y - 1

y² + 4y - 1 = 4

Re-arranging, we have

y² + 4y - 1 - 4 = 0

y² + 4y - 5 = 0

Factorizing the quadratic equation, we have

y² - y + 5x - 5 = 0

y(y - 1) + 5(y - 1) = 0

(y + 5)(y - 1) = 0

⇒ y + 5 = 0 and y - 1 = 0

⇒ y = - 5 and y = 1

Now, x² = 4y - 1

⇒ x = ±√(4y - 1)

So, substituting y = -5 into the equation, we have

x = ±√(4y - 1)

x = ±√[(4 × -5) - 1)]

= ±√(- 20 - 1)

= ±√-21

Since the square root is negative, this answer is invalid.

Substituting y = 1 into x, we have

x = ±√(4y - 1)

x = ±√(4(1) - 1)

x = ±√(4 - 1)

x = ±√3

So, the points of intersection are (√3, 1) and (-√3, 1)

Mr. Moore needs 13.5 cubic feet of soil to fill the planter box.

To calculate the volume of the rectangular prism planter box, we need to multiply the length, width, and height of the box.

Volume = length x width x height

V = 4.5 ft x 2 ft x 1.5 ft

V = 13.5 cubic feet

Therefore, Mr. Moore needs 13.5 cubic feet of soil to fill the planter box.

It is important to note that the volume of the box represents the amount of space inside the box and does not take into account any obstructions or irregularities that may be present inside the box.
