Answer:

x = 7

Step-by-step explanation:

In a trapezoid

each lower base angle is supplementary to the upper base angle on the same side , then

∠ S + ∠ V = 180

8x - 21 + 145 = 180

8x + 124 = 180 ( subtract 124 from both sides )

8x = 56 ( divide both sides by 8 )

x = 7

The values of the inequalities are -5 ≤ x ≤ 1 and 2/3 ≤ x ≤ 1

What are inequalities?

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.

Here, we have

Inequality 1: f(4x - 3) ≥ f(2 - x²), Df = (-8 , 4)

The function increases at (-8,4).

So, we have:

4x - 3 ≥ 2 - x²

Rewrite as:

x² + 4x - 2 - 3 ≥ 0

Evaluate the like terms

x² + 4x - 5 ≥ 0

Expand

x² + 5x - x - 5 ≥ 0

Factorize the expression

x(x + 5) - 1(x + 5) ≥ 0

Factor out x + 5

(x - 1)(x + 5) ≥ 0

Solve for x

x ≥ 1 or x ≥ -5

Rewrite as:

-5 ≤ x ≤ 1

Inequality 2: g(3x² - 2x) ≥ g(3x - 2), Dg = all real numbers

g(3x² - 2x) ≥ g(3x - 2)

(3x² - 2x) ≥ (3x - 2)

Evaluate the like terms

3x² - 2x -3x + 2 ≤ 0

3x² - 5x + 2 ≤ 0

3x² - 3x -2x + 2 ≤ 0

3x(x-1) -2(x-1) ≤ 0

Solve for x

x≤1 or x≤2/3

Hence, the values of the inequalities are -5 ≤ x ≤ 1 and 2/3 ≤ x ≤ 1

B. The age of the new player is 23.1 years

The mean age of the team can be obtained as illustrated below:

Mean age = ∑fx / ∑f

Mean age = [(19 × 2) + (20 × 3) + (21 × 1) + (22 × 4) + (23 × 1)] / (2 + 3 + 1 + 4 + 1)

Mean age = 230 / 11

Mean age = 20.9 years

Thus, the mean age of the team is 20.9 years

The age of the new player can be obtained as follow:

New mean = (mean of previous + age of new player) / 2

22 = (20.9 + age of new player) / 2

Cross multiply

22 × 2 = 20.9 + age of new player

44 = 20.9 + age of new player

The probability that a randomly selected athlete uses a stair climber for,

(a) P(X < 18) = 0.2514

(b) P(22 < X < 31) = 0.4332

(c) P(X > 30) = 0.0918

Let X be the amount of time an athlete uses a stair climber. Then, X ~ N(22, 6^2) represents a normal distribution with mean 22 and standard deviation 6.

(a) To find the probability that a randomly selected athlete uses a stair climber for less than 18 minutes, we need to calculate P(X < 18).

Z-score for 18 minutes = (18 - 22) / 6 = -0.67

Using a standard normal table or calculator, we find that P(Z < -0.67) = 0.2514.

Therefore, P(X < 18) = P(Z < -0.67) = 0.2514.

(b) To find the probability that a randomly selected athlete uses a stair climber for between 22 and 31 minutes, we need to calculate P(22 < X < 31).

Z-score for 22 minutes = (22 - 22) / 6 = 0

Z-score for 31 minutes = (31 - 22) / 6 = 1.5

Using a standard normal table or calculator, we find that P(0 < Z < 1.5) = 0.4332.

Therefore, P(22 < X < 31) = P(0 < Z < 1.5) = 0.4332.

(c) To find the probability that a randomly selected athlete uses a stair climber for more than 30 minutes, we need to calculate P(X > 30).

Z-score for 30 minutes = (30 - 22) / 6 = 1.33

Using a standard normal table or calculator, we find that P(Z > 1.33) = 0.0918.

Therefore, P(X > 30) = P(Z > 1.33) = 0.0918.

The equation of the line made by the rice flour joining the remaining two opposite banana plants is y = 2x - 7.

We are given the coordinates of two opposite banana plants, (3, 4) and (7, 2). Since the consecutive plants are fixed at equal distances, the other two plants will lie on the perpendicular bisector of the line segment joining (3, 4) and (7, 2).

First, let's find the midpoint of the line segment joining (3, 4) and (7, 2):

Midpoint = ((x1 + x2)/2, (y1 + y2)/2) = ((3 + 7)/2, (4 + 2)/2) = (5, 3)

Find the slope of the line segment joining (3, 4) and (7, 2):

Slope = (y2 - y1)/(x2 - x1) = (2 - 4)/(7 - 3) = -2/4 = -1/2

Now, we can use the point-slope form of a linear equation to find the equation of the line made by the rice flour joining the remaining two opposite banana plants:

y - y1 = m(x - x1)

Thus, the cost would be $60 + $56 = $116 for a group of two persons and $60 + $52 + $52 = $164 for a party of three for number n.

The pricing structure for the tour company is based on a base price of $60 per person, which is then discounted by $4 for each additional person up to a maximum of 8 people. This means that for a group of 2 people, the price would be $60 + $56 = $116, while for a group of 3 people, the price would be $60 + $52 + $52 = $164.

The pricing structure incentivizes larger groups to go on the tour, as they can benefit from the discounted price per person. However, the discount stops at 8 people, which means that larger groups do not receive any further discounts. This is likely because the tour company may have a limit on the number of people they can accommodate on a single tour.

It is important for customers to be aware of the pricing structure when considering booking a tour with the company. They should also consider the benefits and drawbacks of going with a larger group versus a smaller one, such as the potential for a more personalized experience with a smaller group versus a more social experience with a larger group. Overall, the pricing structure is designed to be fair and encourage group bookings, while also accommodating the needs of the tour company.

It will take them to meet this goal 10.01 years (or approximately 10 years and 1 month)

To solve this problem, we'll need to use a formula:

Simple interest = Principal × rate × time (in years)

We can rearrange the formula as follows:

Time (in years) = Simple interest / (Principal × rate)

As per the formula, to calculate the time it will take the family to earn the interest, we'll need to know the principal and the rate. These values are not given in the question, so we'll assume that the principal is $10,000 and the interest rate is 7.5 percent (or 0.075 as a decimal).

Simple interest = Principal × rate × time (in years)

$7,507.50 = $10,000 × 0.075 × time (in years)

Divide both sides by $10,000 × 0.075 to isolate the time (in years):

time (in years) = $7,507.50 / ($10,000 × 0.075)

time (in years) = 10.01 years

So, it will take the family 10.01 years (or approximately 10 years and 1 month) to earn $7,507.50 in interest in account 2.

The polynomial function of least degree possible using the given information is: f(x) = -7/3 (x+1)(x-1)(x-3)

What is polynomial function?

A polynomial function is a type of mathematical function that consists of one or more terms, each of which is a constant multiplied by a variable raised to a non-negative integer power.

To construct a polynomial function of least degree possible using the given information, we need to use the fact that the function has real roots at -1, 1, and 3. This means that the function can be factored as follows:

f(x) = a(x+1)(x-1)(x-3)

where a is a constant coefficient that we need to determine.

Next, we need to use the fact that the function passes through the point (2, 7) to determine the value of a. We substitute x=2 and f(x)=7 into the above equation and solve for a:

7 = a(2+1)(2-1)(2-3)

7 = -3a

a = -7/3

Therefore, the polynomial function of least degree possible using the given information is:

f(x) = -7/3 (x+1)(x-1)(x-3)
