Which formula can be used to find the nth term of a geometric sequence where the first term is 8 and the common ratio is –3?

Answer:

8x+ 6 is the translated mathematical expression.

Step-by-step explanation:

We are given the following English expression which are to translate into a mathematical expression:

'The sum of 6 and the product of 8 and x” into a mathematical expression'

Translating it in small chunks:

1. the sum of 6 ---> +6

2. product of 8 and x ---> 8x

Therefore, combining these we get the mathematical expression 8x + 6

For this case we must rewrite the given expression mathematically.

The sum of 6 and something else is written as:

[tex]6+[/tex]

The product of 8 and x is written as:

[tex]8x[/tex]

Finally, the expression is given by:

[tex]6 + 8x[/tex]

Answer:

The expression is given by:

[tex]6 + 8x[/tex]

Answer:

80 times 13.58 =1086400

Step-by-step explanation:

The equations representating the number of boxes Alonzo, Cory, and Bennett loaded are b = 0.7m, b = 1.4m, and b = 0.35m respectively. This is calculated based on the fact that Alonzo loaded 14 boxes in 20 minutes, and Cory and Bennett loaded twice and a quarter as much as Alonzo respectively.

On the basis given, Alonzo loaded 14 boxes in 20 minutes. So, the number of boxes loaded per minute, m , can be calculated as b = 14 boxes ÷ 20 minutes = 0.7 m.

Cory loaded twice as many boxes as Alonzo, so his equation is b = 2 * 0.7m = 1.4m.

Bennett loaded one fourth as many boxes as Cory, which means Bennett's equation can be determined as b = 1/4 * 1.4m = 0.35m.

Based on this, the true statements are:

The number of boxes loaded by each player can be represented by different equations. Alonzo and Bennett loaded boxes at the same rate.

Explanation:

The proportional relationship between the number of boxes, b, that each player loaded onto the truck and the number of minutes, m, spent loading boxes can be represented by the equations:

Alonzo: b = 0.71m

Bennett: b = 0.25c (where c is the number of boxes Cory loaded)

Cory: b = 2a (where a is the number of boxes Alonzo loaded)

Based on the given rates, Alonzo and Bennett loaded boxes at the same rate.

Step-by-step explanation:

X=3

1. simplify both sides of the equation by combining like terms

2. add 5 to both sides

3.divide both sides by -2

For this case we have the following equation:

Final answer:

The function represented by the given set of points is f(x) = -x^2 - 2x + 3.

Explanation:

To determine the function represented by the given set of points, we can use the general form of a quadratic equation, y = ax^2 + bx + c. Substituting the points (-3,0), (-2,3), and (-1,4) into the equation, we can set up a system of equations and solve for the values of a, b, and c. The resulting function is f(x) = -x^2 - 2x + 3, which corresponds to option C.

Volume of a pyramid is:

V = ⅓ AH

where A is the area of the base and H is the height of the pyramid.

The base is a triangle.  Area of a triangle is:

A = ½ bh

where b is the base length and h is the height.

A = ½ (4)(1.5)

A = 3

V = ⅓ (3)(9)

V = 9

The volume is 9 in³.

The volume of the triangular pyramid with a triangular base is 9 cubic inches.

The volume of the triangular pyramid with a height h and base area B is

Volume = 1/3 × B × h cubic units

The area of a triangle is 1/2 × b × h sq. units

where b - base and h - height the triangle.

It is given that a triangular pyramid has a triangular base with

base length b = 4 inches

height of the triangle h = 1.5 inches and

height of the pyramid = 9 inches

So, the volume of the pyramid = 1/3 × B × h

Where base area B = 1/2 × b × h

⇒ B = 1/2 × 4 × 1.5

       = 3.0 sq. inches

And the volume = 1/3 × 3.0 × 9

                             = 9 cubic inches.

Therefore, the volume of the given triangular pyramid is 9 cubic inches.

The function which has a range of y < 3 is y=-(2)x +3. This is an example of a linear function where the slope is negative and the y-intercept is 3. This means that the y-values (the range) will always be less than 3. This is because the value of y will decrease by 2 for every increase in x, starting from y=3. For the other functions, the range of y-values is not consistently less than 3.

Answer:

(- 1, 0), (9, 0)

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here (h, k) = (4, 75), so

y = a(x - 4)² + 75

To find a substitute (0, 27) into the equation

27 = a(- 4)² + 75 , that is

27 = 16a + 75 ( subtract 75 from both sides )

16a = - 48 ( divide both sides by 16 )

a = - 3, thus

y = - 3(x - 4)² + 75 ← equation in vertex form

To obtain the x- intercepts let y = 0

- 3(x - 4)² + 75 = 0 ( subtract 75 from both sides )

- 3(x - 4)² = - 75 ( divide both sides by - 3 )

(x - 4)² = 25 ( take the square root of both sides )

x - 4 = ± [tex]\sqrt{25}[/tex] = ± 5

Add 4 to both sides

x = 4 ± 5, hence

x = 4 - 5 = - 1 or x = 4 + 5 = 9

Substitute these values into the equation for corresponding values of y

x = - 1 : y = - 3(- 5)² + 75 = - 75 + 75 = 0 → (- 1, 0)

x = 9 : y = - 3(5)² + 75 = = 75 + 75 = 0 → (9, 0)

The x- intercepts are (- 1, 0), (9, 0)

Answer:

The x intercepts are (-1, 0) and (9, 0).

Step-by-step explanation:

We can write the equation in vertex form:

y = a(x - b)^2 + c

Here b = 4 and c = 75 so we have

y = a(x - 4)^2 + 75 where a is a constant to be found.

The y-intercept is (0,27) so

27 = a(0 - 4)^2 + 75

16a = 27 - 75

a = -48/16 = -3

So to find the x-intercepts we solve the equation:

-3(x - 4)^2 + 75 = 0

(x - 4)^2 = -75 / -3 = 25

x - 4 = +/- √25

x =   5+ 4 = 9 , -5 + 4 = -1.

Answer:

Step-by-step explanation:

We can find the vertex either by completing the square or taking advantage of the simple formula x = -b / (2a), which provides the x-coordinate of the vertex.

Here a = 2, b = -20 and c = 100.  Then the x-coordinate of the vertex is at

x = -(-20) / (2*2), or x = 5.

Next, evaluate y = 2x^2 - 20x + 100 to find the y-coordinate of the vertex.  It is y(5) = 2(5^2) - 20(5) + 100, or y(5) = 50 - 100 + 100, or 50.  y = 50.

The vertex is at (5, 50).  This states that the stock reaches its minimum value, $50 per share), after 5 months.  From that time on, the stock appreciates (increases) in value.

(x²/4) + (y²/16) ≤ 1

Step-by-step explanation:

The general form of the ellipse in the graph is

x²/4 + y²/16 = 1

we want to find the inequality which represents the shaded area this will determine whether which of the following 2 choices are correct

Choice 1: x²/4 + y²/16 ≥ 1

Choice 2: x²/4 + y²/16 ≤ 1

we note that point (0,0) lies inside the shaded area. Which means if we substitute (0,0), it should create an equality that is valid.

try choice 1: 0²/4 + 0²/16  = 0 ≥ 1 (not valid because obviously zero is smaller than 1)  

try choice 1: 0²/4 + 0²/16  = 0 ≤ 1 (this is valid, hence choice 2  is the answer)

The average rate of change of a function f(x) on the interval [a, b] is given by the formula: (f(b) - f(a)) / (b - a). For the given problem, we are asked to find the average rate of change from x = 0 to x = 4. However, the specific values of f(0) and f(4) on the graph are not provided.
