The 8th term of the sequence is 2.

To find the 8th term of the given number sequence, we can observe that the sequence is decreasing by 3 with each term.

Starting from the first term, which is 23, we subtract 3 repeatedly to get the subsequent terms:

23 - 3 = 20

20 - 3 = 17

17 - 3 = 14

14 - 3 = 11

We can see that each term is obtained by subtracting 3 from the previous term.

To find the 8th term, we continue this pattern:

11 - 3 = 8

8 - 3 = 5

5 - 3 = 2

Therefore, the 8th term of the sequence is 2.

Based on the information provided in the table, Jack has 4h yellow marbles.

To determine the number of yellow marbles in the jar of 275 marbles, we can use the information from the table to find the proportion of yellow marbles in the first pouch.

According to the table, there are 4 yellow marbles out of a total of 25 marbles in the first pouch.

Therefore, the proportion of yellow marbles in the first pouch is 4/25.

To find the number of yellow marbles in the jar of 275 marbles, we can multiply this proportion by the total number of marbles in the jar.

Number of yellow marbles = (4/25) x 275 = 44

Therefore, there are 44 yellow marbles in the jar of 275 marbles.

The length of the variable are as follows;

x = 27.4 units

y = 12.7 units

When two secants intersect outside a circle, the circle divides the secants into segments that are proportional with each other.

Therefore,

5(x + 5) = 6(21 + 6)

5x + 25 = 126 + 36

5x + 25 = 162

5x = 162 - 25

5x = 137

x = 137 / 5

x = 27.4 units

Let's find variable y as follows;

If a secant and a tangent are drawn to a circle from the same external point, the product of the length of the secant and its external segment equals the square of the tangent segment.

Therefore,

y² = (21 + 6)6

y² = 27 × 6

y² = 162

y = √162

The interval on which f(x) is increasing is (-∞, -1) and (3, ∞).

To find the interval on which the function f(x) = x³ - x² - 9x + 3 is increasing, we need to determine where the derivative of the function is positive.

First, let's find the derivative of f(x):

f'(x) = 3x² - 6x - 9

3x² - 6x - 9 = 0

3(x - 3)(x + 1) = 0

x - 3 = 0 or x + 1 = 0

x = 3 or x = -1

These are the critical points of the function.

Let's test a value from each interval:

For x < -1, let's use x = -2:

f'(-2) = 3(-2)² - 6(-2) - 9 = 12 + 12 - 9 = 15 > 0

For -1 < x < 3, let's use x = 0:

f'(0) = 3(0)² - 6(0) - 9 = -9 < 0

For x > 3, let's use x = 4:

f'(4) = 3(4)² - 6(4) - 9 = 12 - 24 - 9 = -21 < 0

From these test values, we can see that f(x) is increasing on the interval (-∞, -1) and (3, ∞).

Therefore, the interval on which f(x) is increasing is (-∞, -1) and (3, ∞).

75,582 different groups of 8 can be formed from the 19 volunteers.

In this case, we want to calculate C(19, 8), which represents the number of ways to choose 8 volunteers from a set of 19 volunteers.

The formula for combinations is given by:

C(n, r) = n! / (r!(n-r)!)

Using this formula,

C(19, 8) = 19! / (8!(19-8)!)

C(19, 8) = 19! / (8!11!)

The information which would be enough to prove the triangles to be congruent are either DE = RP or ∠F = ∠Q.

Given two triangles,

ΔDEF and ΔRPQ.

If ΔDEF is congruent to ΔRPQ, then the corresponding vertices of D, E and F are R, P and Q respectively.

Already we have from the figure,

∠D = ∠R

DF = RQ

Now, it is enough to prove either DE = RP or ∠F = ∠Q.

When DE = RP, by SAS congruence theorem, corresponding two sides and the included angle of each triangle are equal and thus triangles are congruent.

When ∠F = ∠Q, by ASA congruence theorem, corresponding two angles and the included side of each triangle are equal and thus triangles are congruent.

The force of gravity on the rocket is 30 N/kg, the mass of the rocket stays constant while its weight varies

The force of gravity is the force exerted on an object by the earth or a planet.

Given that the force of gravity on an object when it is launched is 30 N/kg. This is three times larger than Earth's gravity. To determine what happens to the mass and weight of the object when gravity is 30 N/kg, we proceed as follows.

We know that weight, W = mg where

Since gravity g = 30 N/kg, we have that

W = mg

= m × 30 N/kg

= 30m

Now, we know that mass is an intrinsic property and weight is an extrinsic property. This means that the mass of the object is constant but its weight can change based on the object's position and depends on the amount of mass.

So, since the force of gravity on the rocket is 30 N/kg, the mass of the rocket stays constant while its weight varies

The dimensionless product relating the torque, rotation rate, volume, and air density is:

Pi = (torque) * (rotation rate)² * (volume)^(1/3)

To find a dimensionless product relating the torque (ML²T⁻²) produced by an automobile engine, the engine's rotation rate (T⁻¹), the volume V of air displaced by the engine, and the air density p, we can make use of the Buckingham Pi theorem.

The Buckingham Pi theorem states that in a physical problem involving n variables with k fundamental dimensions, there will be n - k dimensionless quantities that can be formed as products of powers of the original variables.

In this case, we have 4 variables with 3 fundamental dimensions: torque (M L² T⁻²), rotation rate (T⁻¹), volume (L³), and air density (M L⁻³). Therefore, we expect to have 4 - 3 = 1 dimensionless product.

Let's define the dimensionless product (Pi) as:

Pi = (torque)ᵃ * (rotation rate)ᵇ * (volume)ᶜ * (air density)ᵈ

To determine the powers (a, b, c, d), we equate the dimensions on both sides of the equation:

M L² T⁻² = (M)ᵃ * (T⁻¹)ᵇ * (L³)ᶜ * (M L⁻³)ᵈ

Equating the dimensions of mass (M):

1 = a + d

Equating the dimensions of length (L):

2 = 3c - 3d

Equating the dimensions of time (T):

-2 = -b

Solving these equations, we find:

a = 1

b = 2

c = 1/3

d = 0

Answer:

x = 2

y = -3

Step-by-step explanation:

y = x - 5

x + y = -1

To solve the given system of equations, we can use the method of substitution.

That is, you can replace y with ( x - 5 ).

x + y = -1

x + (x - 5 ) = -1

x + x - 5 = -1

Combine like terms.

2x - 5 = - 1

Add 5 to both sides.

2x = - 1 + 5

2x = 4

Divide both sides by 2.

x = 2

And now let us find the value of y by replacing x with 2.

y = x - 5

y = 2 - 5

y = -3

The farmer sold 3.6 kilograms of apples at the farmers market.

To find the weight of apples the farmer sold at the farmers market, we need to subtract the weight of pears from the total weight.

We have,

3/5 of the weight is pears, the weight of pears

= (3/5) x 7.2 kilograms.

= 3.6 Kg

Since the remaining weight is apples, we can calculate the weight of apples by subtracting the weight of pears from the total weight:

Weight of apples = Total weight - Weight of pears

= 7.2 - 3.6

= 3.6 kilograms

Therefore, the farmer sold 3.6 kilograms of apples at the farmers market.
