The differential equation with initial conditions describing the motion is F = -k * (s(t) + 5) - 6g and the displacement of the mass from its equilibrium position as a function of time s(t) = (3 * r2 * e^(r1*t)) / (r2 - r1) + (3 * r1 * e^(r2*t)) / (r1 - r2)

The differential equation for the motion of the mass is given by Newton's Second Law, F = ma:

F = -k * (s(t) + 5) - 6g

where k is the spring constant, s(t) is the displacement from the equilibrium position, and g is the acceleration due to gravity. The initial conditions are s(0) = 3 and s'(0) = 0, since the spring is initially stretched an additional 3 cm and released from rest.

We can rearrange the equation to get:

s''(t) + (k/6) * s(t) = -5k/6 - g

This is a second-order linear homogeneous differential equation with constant coefficients. The general solution is:

s(t) = C1 * e^(r1*t) + C2 * e^(r2*t)

where r1 and r2 are the roots of the characteristic equation:

r^2 + (k/6) * r = -5k/6 - g

Using the quadratic formula, we get:

r1,2 = -(k/12) ± √((k/12)^2 + 5k/6 + g)

We can find the values of C1 and C2 by applying the initial conditions:

s(0) = C1 + C2 = 3

s'(0) = C1 * r1 + C2 * r2 = 0

Solving for C1 and C2, we get:

C1 = (3 * r2) / (r2 - r1)

C2 = (3 * r1) / (r1 - r2)

Substituting back into the general solution, we get:

s(t) = (3 * r2 * e^(r1*t)) / (r2 - r1) + (3 * r1 * e^(r2*t)) / (r1 - r2)

This is the displacement of the mass from its equilibrium position as a function of time.

The expression√{y²-81} can be simplifies to trigonometry as  9|tanx|.

If an algebraic expression has no like terms and no parenthesis, it is said to be in its simplest form. Use the Distributive Property to add or subtract the coefficients to combine like terms with variables. You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression.

We start by substituting 9 sec x for y:

√{y²-81} = √{(9 sec x)²-81}

= √{81(sec²x) - 81}

= √{81(sec²x-1)}

= 9√{sec²x-1}

Using the trigonometric identity sec²x - 1 = tan²x, we can simplify further:

9√{sec²x-1} = 9√{tan²x}

= 9|tanx|

Therefore, the simplified expression is 9|tanx|.

The popcorn container can hold 432 cubic inches of popcorn.First, we need to find the volume of the popcorn container. The formula for the volume of a square pyramid is:

Volume = (1/3) * base area * height

To find the base area, we need to first find the area of one of the square sides. Since each side measures 6 inches, the area of one square side is:

Area = side length^2 = 6^2 = 36 square inches

Since the popcorn container is a square pyramid, it has four identical square sides, so the total base area is:

Base area = 4 * 36 square inches = 144 square inches

Now we can plug in the values for the base area and height into the formula for volume:

Volume = (1/3) * 144 square inches * 9 inches

Volume = 432 cubic inches

So the popcorn container can hold 432 cubic inches of popcorn.

The fraction of the material that each strip represents is 1/12 of a yard.

Susan bought 1/3 of a yard of material to use for the border for the blanket. She cut the material into 4 same-size strips. The problem is asking for the part of a whole yard that each strip represents.

Since Susan has 1/3 of a yard of material and she cut it into 4 same-size strips, we can use division to find the fraction of the material that each strip represents.

Therefore, the fraction of the material that each strip represents is 1/3 ÷ 4.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of 4 is 1/4, so we can rewrite the expression as:

1/3 ÷ 4 = 1/3 × 1/4

Now we can multiply the fractions:

1/3 × 1/4 = 1/12

The area of the rectangle is 31/3 square centimeters or 10 1/3 square centimeters as a mixed number.

To find the area of the rectangle, we need to multiply its length by its width.

First, we need to convert the mixed numbers to improper fractions:

Length = 5 1/6 cm = (6 × 5 + 1)/6 = 31/6 cm

Width = 2 2/7 cm = (7 × 2 + 2)/7 = 16/7 cm

Now, we can multiply the two fractions to get the area of the rectangle:

Area = length × width

= (31/6 cm) × (16/7 cm)

= (31 × 16) / (6 × 7) cm²

= 496/42 cm²

= 248/21 cm²

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF), which is 8:

248/21 cm² = (8 × 31)/ (8 × 3) cm²

= 31/3 cm²

Answer:

Factored completely:

2x2(−x−2)(x−7)

Step-by-step explanation:

Answer:∠A = 9

Step-by-step explanation:In a Parallelogram opposite angles are always equal thus,  14x - 4 = 15x - 13.

Start by isolating the variable on one side of the equation. You can do this by subtracting 14x from both sides:

14x - 4 - 14x = 15x - 13 - 14x

Simplifying the left side gives:

-4 = x - 13

Now, isolate x by adding 13 to both sides:

-4 + 13 = x - 13 + 13

Simplifying the left side gives:

9 = x

Therefore, the solution to the equation 14x - 4 = 15x - 13 is x = 9

A matched-subjects experiment produced a t statistic with a df of 17.

34 subjects participated in this study.

Both a repeated-measures experiment and a matched-subjects experiment share the following characteristics when used to compare two treatment conditions:

1. They both use the same t statistic.
2. The researcher computes difference scores to compute a t statistic.
3. The researcher must compute an estimated standard error for the mean difference score to compute a t statistic.

For a repeated-measures experiment comparing two treatment conditions, the t statistic has a df of 31.

The number of subjects that participated in this study is 32 because the degrees of freedom (df) for a repeated measures experiment is calculated as (number of subjects - 1),

so 31 + 1 = 32.

A matched-subjects experiment produced a t statistic with a df of 17.

In this case,

the number of subjects that participated in the study is 34 because the degrees of freedom (df) for a matched-subjects experiment is calculated as (number of pairs - 1),

since there are two subjects in each pair, 17 + 1 = 18 pairs, which means 18 * 2 = 34 subjects.
