Answer:

  ∠FGH = ∠HGI = 29°

  ∠FGI = 58°

Step-by-step explanation:

GH is marked as an angle bisector, so we have ...

  ∠FGH = ∠HGI

  2x -9 = 3x -28

  19 = x . . . . . . . . . . . . add 28-2x to both sides

Of course, the angle FGH is the sum of its parts. Then the angle measures are  ...

  (2x -9)° = (2·19 -9)° = 29°

  ∠FGH = ∠HGI = 29°

  ∠FGI = 58°

The major branch of statistics that deals with making inferences about a population based on a sample is called inferential statistics.

In this scenario, you collected data from a sample of eight classmates and calculated the average score to be 65.

Based on this sample, you made an inference about the entire class, stating that the average test score for the whole class was less than 70. This inference is an example of using inferential statistics. Inferential statistics allows us to draw conclusions and make predictions about a larger population based on a smaller sample.

By using statistical techniques and assumptions, we can estimate parameters, such as the population mean, using sample statistics. This helps us make informed decisions and generalizations about a population when it is not feasible or practical to collect data from the entire population.

Answer:

you would use the thousands place value.

Step-by-step explanation:

The volume of the solid generated by revolving the region bounded by y = 2√ and y = 0 about the x-axis is approximately 20.943 cubic units.

To calculate the volume, we can use the method of cylindrical shells. We divide the region into infinitesimally thin vertical strips, each with width dx. The height of each strip is the difference between the upper and lower curves, which in this case is 2√x - 0 = 2√x.

The circumference of the shell is 2πx, giving us the formula for the volume of each shell as V = 2πx * 2√x * dx. Integrating this expression over the interval [0, 4] (the region bounded by the curves), we obtain the total volume of the solid as ∫(0 to 4) 2πx * 2√x * dx. Evaluating this integral gives us the value of approximately 20.943 cubic units.

In summary, the volume of the solid generated by revolving the region bounded by y = 2√ and y = 0 about the x-axis is approximately 20.943 cubic units. This is calculated using the method of cylindrical shells, integrating the volume of each infinitesimally thin vertical strip over the given interval.

A typical shower drain can remove 480 gallons of water in 3 hours.

For the first-rate;

1,440 gallons in 3 hours

We calculate the unit rate.

By Dividing the total volume by the total time,

1440 / 3 = 480 gallons/ hours

For the second rate:

960 gallons in 120 minutes

Converting minutes to hours:

120 minutes = 2 hours

We calculate the unit rate.

By dividing the total volume by the total time,

960 / 2 = 480 gallons / hour

For the third rate:

720 gallons in 1.5 hours

We calculate the unit rate.

By dividing the total volume by the total time,

720 / 1.5 = 480 gallons / hour

Now,

480 gallons/ hour = 480 / 60 gallons/ minute = 80 gallons per minute

Answer: 47 degrees

Step-by-step explanation:

The measure of an angle BOC from the given figure is 47°.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

Given that, m∠AOC is a straight angle, m∠BOC=6x+29° and m∠AOB=3x+124°.

We know that, a straight angle measures 180°.

Now, m∠BOC+m∠AOB=m∠AOC

6x+29°+3x+124°=180°

9x+153°=180°

9x=27°

x=3°

So, m∠BOC=6x+29°

=6×3+29°

= 47°

Therefore, the measure of angle BOC is 47°.

The coordinates of the first point of intersection in rectangular form are (x, y) = ((5/2), (5/2)).

To find the points of intersection between the polar curves r = 5 sin(θ) and r = 5 cos(θ), we need to equate the two equations and solve for θ. Let's start by setting the two equations equal to each other:

5 sin(θ) = 5 cos(θ)

Dividing both sides by 5 gives:

sin(θ) = cos(θ)

Now, we can use the trigonometric identity sin(θ) = cos(90° - θ). Replacing cos(θ) with sin(90° - θ), the equation becomes:

sin(θ) = sin(90° - θ)

Since the sine function is equal to itself for any angle plus multiples of 360°, we can write:

θ = 90° - θ + 360°  x  n

Here, n represents any integer value. Solving for θ, we get:

2θ = 90° + 360°  x  n

Dividing both sides by 2, we have:

θ = 45° + 180°  x  n

Now, let's substitute this value of θ back into the original equation r = 5 sin(θ) (or r = 5 cos(θ)) to find the corresponding r-values.

For θ = 45°:

r = 5 sin(45°) = 5 cos(45°)

Using the values of sine and cosine for 45°, we get:

r = 5  x  √(2)/2 = 5  x  √(2)/2

Simplifying further, we have:

r = (5/2)  x  √(2)

Therefore, the coordinates of the first point of intersection are (r, θ) = ((5/2)  x  √(2), 45°).

Now, let's consider the value of θ for n = 1:

θ = 45° + 180°  x  1 = 45° + 180° = 225°

For θ = 225°:

r = 5 sin(225°) = 5 cos(225°)

Using the values of sine and cosine for 225°, we get:

r = 5  x  (-√(2)/2) = -5  x  √(2)/2

Simplifying further, we have:

r = (-5/2)  x  √(2)

Therefore, the coordinates of the second point of intersection are (r, θ) = ((-5/2)  x  √(2), 225°).

To convert these polar coordinates into rectangular coordinates, we can use the formulas:

x = r  x  cos(θ) y = r  x  sin(θ)

For the first point of intersection, (r, θ) = ((5/2)  x  √(2), 45°):

x = ((5/2)  x  √(2))  x  cos(45°) = (5/2)  x  √(2)  x  √(2)/2 = (5/2) y = ((5/2)  x  √(2))  x  sin(45°) = (5/2)  x  √(2)  x  √(2)/2 = (5/2)

Answer:

D-11

Step-by-step explanation:

Answer:

11 is the answer on edge

The time when the food price is most and cheapest is obtained from the extremum value of the function.

The extremum of a function is a maximum or minimum value of the function.

The function that models the food-price is I(t) = 0.00009045·t⁵ + 0.001438·t⁴ - 0.0656·t³ + 0.4598·t² - 0.6270·t + 99.33

Where;

t = The number of years since 1984

I(3) = 100

The time when the food is cheapest or most expensive can be obtained by differentiating the function for food-price and equating the result to 0 as follows;

I'(t) = 0.00009045×5·t⁴ + 0.001438×4·t³ - 0.0656×3·t² + 0.4598×2·t - 0.6270 = 0

Factoring the result, using a graphing calculator, we get;

(t - 0.823)·(t - 5.131)·(t - 11.05)·(t + 29.72) = 0

The values of the minimum and maximum values are therefore';

I(0.823) = 0.00009045×0.823⁵ + 0.001438×0.823⁴ - 0.0656×0.823³ + 0.4598×0.823² - 0.6270×0.823 + 99.33 ≈ 99.08

I(5.131) = 0.00009045×5.131⁵ + 0.001438×5.131⁴ - 0.0656×5.131³ + 0.4598×5.131² - 0.6270×5.131 + 99.33 ≈ 100.67

I(11.05) = 0.00009045×11.05⁵ + 0.001438×11.05⁴ - 0.0656×11.05³ + 0.4598×11.05² - 0.6270×11.05 + 99.33 ≈ 96.38

I(-29.72) = 0.00009045×(-29.72)⁵ + 0.001438×(-29.72)⁴ - 0.0656×(-29.72)³ + 0.4598×(-29.72)² - 0.6270×(-29.72) + 99.33 = 1270.8

Therefore, the food price when the food was cheapest is $99.08

The time when the food is most cheapest where 0 ≤ t ≤ 10 is t = 0.823 years ≈ 1 years

Similarly, the food price when the food was most expensive in a 10 year time frame is $100.67

The time when the food is most expensive is t ≈ 5.131 years ≈ 5 years

Answer:

Option (4)

Step-by-step explanation:

We Fix it Computer Repair charges for it's services as per equation given as,

C = 30h + 90

Here, C = Total cost

h = Number of hours worked

This equation is in the form of a linear equation,

y = mx + b

Here, m = slope of the equation

And slope of the equation defines the unit rate

Therefore, charges for each hour of the first company = $30

Table given in the question represents the charges of another company John's Compute Repair.

There is a common difference in each successive term of the Total Cost of the table,

Common difference = 100 - 55 = 45

Therefore, this table represents a linear function.

Slope of the linear function passing through \((x_1,y_1)\) and \((x_2,y_2)\) is given by the expression,

Slope = \(\frac{y_2-y_1}{x_2-x_1}\)

Slope of the function represented by the table = \(\frac{100-55}{2-1}\)

                                                                              = 45

Therefore, per hour charges by the second company = $45

Difference in the charges = $45 - $30

                                           = $15

John's Computer Repair charges more by $15.

Option (4) is the correct option.

Answer:

2/25 or 0.08%

Step-by-step explanation:

The jump from -25 to -15 is +10

The jump from -15 to -5 is also +10

The jump from -5 to 5 is also +10

Unfortunately, this pattern doesn't hold up. The jump from 5 to 10 is +5

Because the gap isn't the same each time, this tells us the sequence is not arithmetic.

----------------

We can show the sequence isn't geometric either. Pick any term to divide it over its previous term

-15/(-25) = 0.6

-5/(-15) = 0.333 approximate

The result isn't the same, so we don't have a common ratio and that's why this sequence isn't geometric.

----------------

It seems like your teacher made a typo. Please double check with them to make sure that they typed the correct sequence. I have a feeling that 10 should be 15, but I'm not entirely sure.
