The seventh term of the geometric sequence is -7/32. The nth term of the sequence, a1 is the first term, r is the common ratio, and n is the position of the term

To find the seventh term of a geometric sequence, we can use the formula:

\(an = a1 * r^(n-1),\)

where an represents the nth term of the sequence, a1 is the first term, r is the common ratio, and n is the position of the term we want to find.

In this case, we are given a2 = -7 and r = 1/2.

Using the formula, we can find a1 by substituting n = 2:

a2 = a1 * (1/2)^(2-1).

We know that a2 = -7, so we can rewrite the equation:

-7 = a1 * (1/2)^1,

-7 = a1 * (1/2).

Now, let's solve for a1:

a1 = -7 * (2/1),

a1 = -14.

We have found that the first term, a1, is equal to -14.

Now, we can find the seventh term, a7, by substituting n = 7 into the formula:

a7 = (-14) * (1/2)^(7-1),

a7 = (-14) * (1/2)^6,

a7 = (-14) * (1/64),

a7 = -14/64,

a7 = -7/32.

Therefore, the seventh term of the geometric sequence is -7/32.

Prove parallelogram criteria

what additional information would allow you to prove the quadrilateral is a parallelogram according to the minimum criteria? question 3 options: a) ≅ b) || c) || d) ≅

Answer

To determine if a quadrilateral is a parallelogram, we typically look for certain properties. However, the options you provided (a) ≅, b) ||, c) ||, d) ≅) seem to be symbols rather than additional information.

For the minimum criteria to prove a quadrilateral is a parallelogram, we typically require one of the following:

Opposite sides are parallel: If you can provide information indicating that the opposite sides of the quadrilateral are parallel, such as stating that AB || CD and AD || BC, it would help establish the quadrilateral as a parallelogram.

Opposite sides are congruent: If you can provide information indicating that the opposite sides of the quadrilateral are congruent, such as stating that AB ≅ CD and AD ≅ BC, it would also support the claim that the quadrilateral is a parallelogram.

Diagonals bisect each other: Another property of parallelograms is that their diagonals bisect each other. If you can provide information showing that the diagonals of the quadrilateral bisect each other, it would serve as evidence for the parallelogram.

Please provide any specific measurements, angles, or relationships among the sides or diagonals of the quadrilateral to further analyze and determine if it meets the minimum criteria for a parallelogram.

Let θ be equal to 855∘. Sketch θ in standard position. θ = 855∘ is in the fourth quadrant of the coordinate plane θ = 855∘

Hence, we sketch θ in the standard position with its initial side along the positive x-axis.

Find an angle between 0∘ and 360∘ that is coterminal with θ.

The angle between 0∘ and 360∘ that is coterminal with θ is given by:

θ1 = θ - n × 360∘θ1 = 855∘ - 2 × 360∘θ1 = 855∘ - 720∘θ1 = 135∘

Find an angle between −360∘ and 0∘ that is coterminal with θ.

The angle between −360∘ and 0∘ that is coterminal with θ is given by:

θ2 = θ + n × 360∘θ2 = 855∘ + 2 × 360∘θ2 = 855∘ + 720∘θ2 = 1575∘

Answer:

a. Equation: 0.8x+30 = 1.2x+14

b. Solution: 40 Stickers

Step-by-step explanation:

"per sticker" means there will be a variable which will be how many stickers he buys next to the price and the fee is the amount of money that will be added onto the fee price.

Company A equation: 0.8x+30

Company B equation: 1.2x+14

You will set these equal to each other to find the number of stickers which cost the same for both companies, then solve for x by doing inverse operations.

0.8x+30 = 1.2x+14   [subtract 14 from both sides]

0.8x+16 = 1.2x          [subtract 0.8x from both sides]

16 = 0.4x                  [divide 0.4 from both sides]

x = 40                       [The solution is 40 stickers]

The time taken for the water level in the tank to drop from 3 to 0.5 meters above the bottom cannot be determined without additional information.

To calculate the time taken, we need to know the flow rate or discharge rate of the water from the tank. This information is not provided in the question. The time taken to drain the tank depends on factors such as the diameter of the outlet pipe, the pressure difference, and any restrictions or obstructions in the flow path.

If we assume a known discharge rate, we can use the principles of fluid mechanics to calculate the time. The volume of water that needs to be drained is the difference in the volume of water between 3 meters and 0.5 meters above the bottom of the tank. The flow rate can be determined using the pipe diameter and other relevant factors. Dividing the volume by the flow rate will give us the time taken.

However, since the discharge rate is not given, we cannot perform the calculation and determine the time taken accurately.

Without knowing the discharge rate or additional information about the flow characteristics, it is not possible to calculate the time taken for the water level in the tank to drop from 3 to 0.5 meters above the bottom.

Answer:

To graph the function f(x) = 2sin(x) - 2 by hand, we can use the following steps:

Step 1: Find the amplitude

The amplitude of the function is the absolute value of the coefficient of the sine function, which is 2 in this case. Therefore, the amplitude is 2.

Step 2: Find the period

The period of the function is given by the formula 2π/b, where b is the coefficient of x in the sine function. In this case, b = 1, so the period is 2π/1 = 2π.

Step 3: Find the midline

The midline is the horizontal line that the graph oscillates around. For the sine function, the midline is the y-value of the function when there is no vertical shift. In this case, the midline is y = -2.

Step 4: Find the y-intercept

The y-intercept is the value of the function when x = 0. Plugging in x = 0, we get f(0) = 2sin(0) - 2 = -2. Therefore, the y-intercept is -2.

Step 5: Sketch the graph

Based on the amplitude, period, midline, and y-intercept we just found, we can sketch the graph of the function as follows:

- The graph oscillates between y = 2 and y = -6, with a midline at y = -2.

- The graph starts at (0, -2), then goes up to (π/2, 0), down to (π, -2), down further to (3π/2, -4), and back up to (2π, -2).

- The graph is symmetric about the midline.

Therefore, the information about the function is:

Amplitude: 2 (The distance from the midline to the maximum or minimum of the graph is 2.)

Period: 2π (The graph completes one full cycle over a horizontal distance of 2π.)

Midline: y = -2 (The horizontal line that the graph oscillates around.)

y-intercept: -2 (The value of the function when x = 0.)

If y = ax + 3x - a' has a gradient of 5 when x= -2, then the value of y when x = -3 will be 0.

We must first determine the value of the constant a' in order to determine the value of y when x = -3.

The coefficient of x, which is a + 3, determines the gradient of y = ax + 3x - a'. The gradient at x = -2 is given to be 5. As a result, we may construct the equation shown below:

a + 3 = 5

⇒ a = 2

When we enter the value of a, x, and the gradient into the equation, we may get the value of a'.

5 = 2(-2) + 3(-2) - a'

⇒ 5 = -4 - 6 - a'

⇒ a' = -15

By entering the values of a, a', and x into the equation, we can now determine the value of y for x = -3:

y = ax + 3x - a'

y = 2(-3) + 3(-3) - (-15)

y = -6 - 9 + 15

y = 0

Hence, the value of y is 0 when x = -3.

The measurement of the angle 1 in the given parallel lines is 35° whereas the value of x is 15.

Parallel lines are those straight lines that are always the same distance apart from each other.

Given that, two lines RS and TU are parallel, and ∠ 7 = 3x-10 and ∠ 3 = 2x+5,

We need to find ∠ 1

Since, ∠ 7 and ∠ 3 are corresponding angles between two parallel lines therefore, both are congruent,

Therefore,

3x-10 = 2x+5

x = 15

Now, ∠ 1 = ∠ 3 as they are vertically opposite angles,

Therefore,

∠ 1 = 2(15)+5

∠ 1 = 35°

Hence, the measurement of the angle 1 in the given parallel lines is 35° whereas the value of x is 15.

3)  \(\mathbf{(-5^{-3})^{-1}=-125}\)

4)  \(\mathbf{(-5^{-3})^0=1}\)

Step-by-step explanation:

We need to solve the exponents

1) \(5^{-3}\)

We know that: \(a^{-1}=\frac{1}{a}\)

\(5^{-3}\\=\frac{1}{5^3}\\=\frac{1}{125}\)

So, we get \(\mathbf{5^{-3}=\frac{1}{125}}\)

2) \(-5^{-3}\)

We know that: \(a^{-1}=\frac{1}{a}\)

\(-5^{-3}\\=-\frac{1}{5^3}\\=-\frac{1}{125}\)

So, we get \(\mathbf{-5^{-3}=-\frac{1}{125}}\)

3) \((-5^{-3})^{-1}\)

We know that: \((a^m)^n=a^{m*n}\)

Using this rule:

\((-5^{-3})^{-1}\\=-5^{-3*-1}\\=-5^{3}\\=-125\)

So, we get \(\mathbf{(-5^{-3})^{-1}=-125}\)

4)  \((-5^{-3})^0\)

We know that: \((a^m)^n=a^{m*n}\)

Using this rule:

\((-5^{-3})^0\\=-5^{-3*0}\\=-5^{0}\\We\:know\:a^0=1\\=1\)

So, we get \(\mathbf{(-5^{-3})^0=1}\)
