The answers are ; a) -5/9, 6/10, -7/11, 8/12, b) f(n) = n/(n+4) and c) f(56) is positive.

A sequence is defined as an arrangement of numbers in a particular order.

A sequence is given ; -1/5, 2/6, -3/7, 4/8.....

Part A

From inspection of the sequence, the pattern is:

i) Add 1 to the numerator of the previous term.

ii) Add 1 to the denominator of the previous term.

iii) Make every other term negative.

Therefore, The next four terms are -5/9, 6/10, -7/11, 8/12

Part B

From inspection of the sequence, we can see that the numerator is the position of the term (n) in the sequence.  So when n = 1 the numerator is 1, when n = 2 the numerator is 2, etc.

The denominator is 5 more than the position of the term in the sequence.  So when n = 2 the denominator is 2 + 4 = 6, and when n = 4 the denominator is 4 + 4= 8.

Hence, the rule can be,

f(n) = n/(n+4)

If n is even, then f(n) is positive.

If n is odd, then f(n) is negative.

Part C

56 is an even number.

As the function f(n) is positive when n is even, the sign of f(56) is positive.

Therefore, the answers are ; a) -5/9, 6/10, -7/11, 8/12, b) f(n) = n/(n+4) and c) f(56) is positive.

The equation in the standard form of a parabola is y = -3x² - 7x - 2

What is the standard form of a parabola?

Another equation that, when graphed, produces a parabola is one written in standard form. Like the letters in the vertex form equation, each letter in the standard form equation provides a nugget of knowledge about the parabola.

Here, we have

The standard equation of a parabola is

y = ax² + bx + c

Substitute the given values in this equation

When x = - 3 and y = -8

-8 = a (-3)² + b (-3) + c

-8 = 9a - 3b + c …. (1)

When x = 0 and y = - 2

-2 = a (0)² + b (0) + c

c = -2....(2)

When x = 2 and y = -28

-28 = a (2)² + b (2) + c

-28 = 4a + 2b + c …. (3)

Equations (1) and (3) can be written as

9a - 3b + c = -8 …. (4)

4a + 2b + c = -28 …. (5)

Multiply equation (4) by 2 and equation (5) by 3 to eliminate 'b'

18a - 6b + 2c = -16

12a + 6b + 3c = -84

Subtracting these equations

30a + 5c = -100

Substitute the value of 'c' here

30a + 5(-2) = -100

30a = -100 + 10

30a = -90

a = -3

Substitute the value of a and c in equation (1)

-8 = 9a - 3b + c

-8 = -27 - 3b -2

-6 = -27 - 3b

3b = -21

b = -7

Here the value of a = -3, b = -7, and c = -2.

Hence, the equation in the standard form of a parabola is y = -3x² - 7x - 2

Answer: Sonya's heart rate increased by 75% after running a mile on the treadmill.

Step-by-step explanation:

To find the percent increase in Sonya's heart rate, we can use the following formula:

Percent increase = (New value - Old value) / Old value * 100

Substituting the given values into the formula, we get:

Percent increase = (133 beats per minute - 76 beats per minute) / 76 beats per minute * 100

Calculating the result, we get:

Percent increase = 57 beats per minute / 76 beats per minute * 100

= 0.75 * 100

= 75%

Therefore, Sonya's heart rate increased by 75% after running a mile on the treadmill.

the percent of change in the average cost of a gallon from year one to year two is 5.8%

The term "average cost" refers to the production cost per unit, which is determined by dividing the overall production cost by the overall number of units produced.

The overall cost of production can also be divided into fixed and variable costs. Since total fixed costs often remain constant, changes in total variable costs are the main cause of changes in average costs.

The average cost of a gallon of gas in year one was $2.95

The average cost of a gallon of gas in year two was $2.78

The change in the average cost of a gallon from year one to year two is

$2.95 - $ 2.78

⇒$0.17

So percent of change in the average cost of a gallon from year one to year two is

($0.17/$2.95) * 100%

⇒ 0.0576 * 100%

⇒ 5.76%

Answer:

  C.  4² +8² ≠ 10²

Step-by-step explanation:

You want to know why it is not possible for the lengths 4, 8, and 10 to form a right triangle.

The side lengths of a right triangle must satisfy the Pythagorean relation:

  a² +b² = c²

These numbers do not:

  4² +8² = 16 +64 = 80 ≠ 10² = 100

A right triangle is not formed because ...

  4² +8² ≠ 10²

__

Additional comment

The smallest Pythagorean Triple is {3, 4, 5}. Doubling these numbers gives {6, 8, 10}. If the two longest sides are 8 and 10, the shortest must be 6 for a right triangle to be formed.

When the side lengths are reduced to a mutually prime set of numbers, their sum must be even.

   4:8:10 reduces to 2:4:5 which has an odd sum.

The length of the major arc AB is 15.44 units

Given:  line x + 2y = −5 and circle of radius 5 centered at the origin

The equation of a circle of radius r whose center is the origin O (0, 0) is given by x²+y² = r². Thus:

x²+y² = 5²

x²+y² = 25

To find the points where the line intersects the circle, we can substitute the equation of the circle into the equation of the line.

Substituting this into the equation of the line, we have;

x + 2y = -5

x²+y² = 25

Solving for x, we have

x = (-5 ±√(33))/2

Since the circle is centered at the origin, both of these points are on the circle. Thus, the coordinates of the points A and B are

A: (-5 +√(33))/2, (-5 - √(33))/4

B: (-5 - √(33))/2, (5 - √(33))/4

To find the length of the major arc AB, we can use the formula

length = θ/360 × 2πr

where r is the radius of the circle, and θ is the central angle formed by points A and B. The central angle can be found using the formula

θ= 180 - 2cos⁻¹((AB² + r² - AC²)/(2 × AB × r))

where AB is the distance between the points A and B, and AC is the distance between point A and the center of the circle (which is the origin)

We can use the Pythagorean Theorem to find AB and AC:

AB = √(((-5 + √(33))/2 - (-5 - √(33))/2)² + ((-5 - √(33))/4 - (5 - √(33))/4)²)

     = √(66)

AC = √(((-5 + √(33))/2)² + ((-5 - √(33))/4)²)

    = √(25 + 33)/2

    = √(58)/2

Substituting these values into the formula for θ, we have

θ = 180 - 2cos⁻¹((√(66)² + 5² - (√(58)/2)²)/(2 × √(66) ×5))

  = 180 - 2cos⁻¹((66 + 25 - 29)/(20))

  = 180 -2cos⁻¹(62/20)

  = 180 - 2cos⁻¹(3.1)

  = 180 - 2 × 1.43

  = 180 - 2.86

  = 177.14

Finally, substituting this value into the formula for the length of the major arc, we have

length = 2 × π × 5 × (177.14/360)

           = 2  × π  5 ×  (0.4925)

           = 2 ×  3.14 ×  5 ×  (0.4925)

           = 6.28 × 5 ×  (0.4925)

           = 31.4 ×  (0.4925)

B) Interest = $84455.31

What is compound interest?

If the interest on a certain principal at a certain rate over a certain period of time increases exponentially rather than linearly, the interest earned is called compound interest.

If p is the principal, r is the rate and n is the time in years, then amount is calculated by

[tex]A = p(1 + \frac{r}{100})^n[/tex]

The difference between the amount and the principal is the compound interest

A)Here,

Let the principal be $p

Rate = 6%

Time = 18 years

Amount = $130000

[tex]130000 = p(1 + \frac{6}{100})^{18}[/tex]

[tex]130000 = p(1 + \frac{3}{50})^{18}[/tex]

[tex]130000 = p(\frac{53}{50})^{18}[/tex]

[tex]130000 = p(1.06)^{18}[/tex]
