The summary of the 3 rules on segments are written below.

The three rules on segments in circles are:

1. When two chords intersect inside a circle, they create four line segments.

The product of the lengths of the two segments of one chord is equal to the product of the lengths of the two segments of the other chord.

2. When two secants intersect outside a circle, they create four line segments.

The product of the length of the secant segment and its external segment is equal to the product of the length of the other secant segment and its external segment.

3. When one secant and one tangent intersect outside a circle, they create three line segments.

The product of the length of the secant segment and its external segment is equal to the square of the length of the tangent segment.

The figure given that has exactly two lines of symmetry is C. Rectangle.

A rectangle has two lines of symmetry.

A line of symmetry is a line that divides a shape into two equal parts that are mirror images of each other. In a rectangle, the two lines of symmetry run through the center of the rectangle, dividing it into two congruent halves. These lines of symmetry are perpendicular to each other and bisect both pairs of opposite sides of the rectangle.

Therefore, a rectangle has two lines of symmetry, one horizontal and one vertical, which make it a symmetrical shape.

The complete table is

Amount of air (ft³)   40   36   32   28   24    20   16   12    8      4     0

The rate of change refers to the speed at which a quantity is changing with respect to time or some other variable.

It is a measure of how quickly or slowly a quantity is increasing or decreasing, and it is often represented as the slope of a graph or function. To fill the table we need to know the rate of change per minute in the air. Using the rate of change we can fill the table as follows  

Here we have

A scuba tank started with 40 cubic feet of air and was empty after a 10-minute dive.

To complete the table, calculate the rate of change of the amount of air in the scuba tank.

We know that the scuba tank started with 40 cubic feet of air and was empty after a 10-minute dive, so we can use this information to find the rate of change:

Rate of change = (final amount - initial amount) / time

Rate of change = (0 - 40) / 10 = -4 ft³/min

The negative sign indicates that the amount of air in the scuba tank is decreasing over time, which makes sense since the diver is using up the air during the dive.

Using this rate of change, we can complete the table as follows:

For 1 min  = 40 ft³ - 4 ft³ = 36 ft³

For 2 min = 36 ft³ - 4 ft³ = 32 ft³

For 3 min = 32 ft³ - 4 ft³ = 28  ft³

Similarly, we can fill the table as given below

This means that the median weight of a female child at 31.48 months is 28 pounds (approximately) base on logarithmic function.

Q1.1: The equation for the amount of money in the account after t years, compounded annually, can be given by:

A = P(1 + r/100)^t

where A is the amount of money in the account after t years, P is the principal amount invested, r is the annual interest rate, and t is the number of years.

Plugging in the values given in the problem, we get:

A = 1200(1 + 4.25/100)^t

Q1.2: We need to solve for t in the equation:

3000 = 1200(1 + 4.25/100)^t

Dividing both sides by 1200, we get:

2.5 = (1 + 4.25/100)^t

Taking the natural logarithm of both sides, we get:

ln 2.5 = t ln (1 + 4.25/100)

Solving for t, we get:

t = ln 2.5 / ln (1 + 4.25/100) ≈ 15.91 years

So, it will take approximately 15.91 years for the amount of money in the account to reach $3000.

Q2.1: To graph the function W = 7.5 + 5.9 ln(M + 1), we can use a graphing calculator or software. Here is a possible graph:

Graph of W = 7.5 + 5.9 ln(M + 1)

Q2.2: To find W ^−1(28), we need to solve the equation:

28 = 7.5 + 5.9 ln(M + 1)

Subtracting 7.5 from both sides, we get:

20.5 = 5.9 ln(M + 1)

Dividing both sides by 5.9, we get:

ln(M + 1) ≈ 3.474576

Taking the inverse logarithm of both sides, we get:

M + 1 ≈ e^3.474576

M ≈ e^3.474576 - 1 ≈ 31.48 months

So, W ^−1(28) ≈ 31.48 months. This means that the median weight of a female child at 31.48 months is 28 pounds (approximately).

what is surface area ?

Surface area is a metric used to determine how much overall space an object occupies. the total volume of the area of surface of a three-dimensional shape. The term "surface area" refers to a three-dimensional shape's entire surface area.

The triangular base has a height of 7 mm and a base of 24 mm, so its area is:

[tex]1/2 * base * height = 1/2 * 24 \ mm * 7\ mm = 84 \ mm^2[/tex]

There are two identical triangular faces, so their combined area is:

[tex]2 * 84 \ mm^2 = 168\ mm^2[/tex]

The three rectangular faces are all the same size, with a length of 24 mm and a height of 7 mm, so the area of each is:

[tex]length * height = 24 \ mm * 7 \ mm = 168 \ mm^2[/tex]

There are three rectangular faces, so their combined area is:

[tex]3 * 168\ mm^2 = 504\ mm^2[/tex]

To find the total surface area, we add the area of the two triangular faces to the area of the three rectangular faces:

[tex]168 \ mm^2 + 504 \ mm^2 = 672 \ mm^2[/tex]

Therefore, the surface area of the triangular prism is 672 square millimeters.

To substitute the value of 4 into the equation, we replace every occurrence of the variable "m" with 4:

m + 2(m + 1) = 14

Plug in m = 4 by replace m with 4 and simplify both sides

4 + 2(4 + 1) = 14

Answer:t = 9.6.

Step-by-step explanation:

The areas of the region between the curves is -40/3square units.

We must first graph the curves in order to identify which one is on top in order to calculate the area of the region bounded by the curves for x in [0, 3]. y = x²− 4x + 1 and y = −x²+ 4x − 5

The vertex of the graph of y = x²− 4x + 1is at (2, -3), and it opens upward. The vertex of the graph of y =−x²+ 4x − 5 is at (2, -1), and it opens downward.

Thus, the curve y = x²− 4x + 1 is on top for x in [0, 1], and the curve y = −x²+ 4x − 5 is on top for x in [1, 3].

To determine which curve is on top, we can set them equal to each other and solve for x:

x²− 4x + 1 = −x²+ 4x − 5

2x² - 8x + 6 = 0

x² - 4x + 3 = 0

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

x = 1 or x = 3

Thus, the curves cross at x = 1 and x = 3. To find which curve is on top between these two points, we can test a point in between, such as x = 2:

y = x²− 4x + 1 = 1

y = −x²+ 4x − 5 = -1

Using integration, we can find the area of the region:

∫[0,1] (x²− 4x + 1) dx + ∫[1,3] (−x²+ 4x − 5) dx

= [(1/3)x³ - 2x² + x] from 0 to 1 + [(-1/3)x³ + 2x² - 5x] from 1 to 3

Answer:

Step-by-step explanation:

C

Step-by-step explanation:

To calculate the probability of getting at least four hearts when dealing five cards from a standard deck, we can use the concept of combinations and probability.

There are a total of 52 cards in a standard deck, and 13 of them are hearts (assuming no jokers). So the probability of drawing a heart on the first card is 13/52, or 1/4.

Now, there are two possible scenarios that would result in at least four hearts:

Four hearts and one non-heart: This can happen in C(13,4) * C(39,1) ways, where C(n, k) is the number of combinations of n items taken k at a time. The first part C(13,4) represents choosing 4 hearts out of 13, and the second part C(39,1) represents choosing 1 non-heart out of the remaining 39 cards. The total number of ways to choose 5 cards from 52 is C(52,5).

Five hearts: This can happen in C(13,5) ways, where C(13,5) represents choosing all 5 hearts out of 13.

So, the total number of favorable outcomes is C(13,4) * C(39,1) + C(13,5), and the total number of possible outcomes is C(52,5). Therefore, the probability of getting at least four hearts is:

P(at least 4 hearts) = (C(13,4) * C(39,1) + C(13,5)) / C(52,5)

Plugging in the values and simplifying, we get:

P(at least 4 hearts) = (C(13,4) * C(39,1) + C(13,5)) / C(52,5)

= (715 * 39 + 1287) / 2,598,960

= 27,885 / 2,598,960

≈ 0.0107566

So, the probability of getting at least four hearts when dealing five cards from a standard deck is approximately 0.0107566 or about 1.08%.
