The Pythagorean theorem is used to determine the length of side c =  12.12cm

According to the Pythagorean theorem, the square of the length of the hypotenuse in a right triangle equals the sum of the squares of the lengths of the other two sides. The hypotenuse is the side that faces the right angle. Consequently, in this instance, c2 = a2 + b2.

given are 20°, 8 cm, and 9 cm.

To determine c's length

replacing the specified values: c^2 = 8^2 + 9^2

c = √(8^2 + 9^2) = √(64 + 81) = √(145)\sc = 12.12 cm

Therefore, side C is 12.12 cm long.

The values that would represent those having type O blood are between 000 and 449, inclusive (Option 3).

The given study states that 45% of Americans have type O blood. This means that out of 100 individuals, 45 would have type O blood. When using a random number generator producing three-digit values from 000 to 999, we can determine which values represent those having type O blood.

Since 45% of Americans have type O blood, it implies that the probability of an individual having type O blood is 0.45. The random number generator produces equally likely values from 000 to 999, where each value has a probability of 1/1000.

To find the values representing those having type O blood, we need to consider the range of values that corresponds to the 45% probability. The inclusive range between 000 and 449 (Option 3) represents the values that have a probability less than or equal to 0.45. Therefore, the values between 000 and 449, inclusive, would represent those having type O blood.

Answer:

(4, 11) is one ordered pair  and (-4, 27) is the other ordered pair

Step-by-step explanation:

(1)  f(x) = x^2 - 2x + 3             (2)    f(x) = -2x + 19

-2x + 19 = x^2 - 2x + 3

x^2 - 16 = 0

(x - 4)(x + 4) = 0

x = 4   or    x = -4                                  -2(4) + 19 = 11

                                                             -2(-4) + 19 = 27

So, when x = 4, y = 11                   and when x = -4, y = 27

(4, 11) is one ordered pair              and (-4, 27) is the other ordered pair

Slant Height Formula

Before learning the slant height formula, let us see what is slant height. The slant height of an object (such as a cone, or pyramid) is the distance along the curved surface, drawn from the edge at the top to a point on the circumference of the circle at the base. In other words, The slant height is the shortest possible distance from the base to the apex along the surface of the solid, denoted either as s or l. The slant height formula helps in the calculation of the slant height in any object.

What is the Slant Height Formula?

The slant height formulas are usually defined for cone and pyramid. They are as follows:

Slant Height of Cone:

s2 = h2 + r2

Slant Height Formula of Pyramid:

(Slant height)2 = (Height)2 + (Base/2)2

In the above two formulas,

s = slant height

h = vertical height

b = base

Given:

b = 20 cm

s = 14.1 cm

then the h = 10.08

Surface area of a square pyramid = a2 + 2al

where,

a = base length of square pyramid

l = slant height or height of each side face

l = (a^2/4 + h^2) ^1/2

a = 20

l = 14.71

SA = 40 + 2(20)(14.71) = 628.4 cm

Step-by-step explanation:

The number of students should be invited to a party to make sure that ap least two of them have the same initials are equals to the 677 (students).

The solution of this problem is obtained by using the pigeonhole principle, which states if there are N boxes and N+1 pigeons, at least two pigeons must be in the same box. We have to determine the number of students invited in party to make make sure that at least two of them have the same initials. Now, first we figure out what N is to solve the problem. Here, box for this problem is labelled by first and last initials. If we are using the A-Z alphabet, then there are 26×26 = 676 possible sets of initials.

As soon as there are N+ 1 or 677 people, at least two must have the same first and last initials. Hence, required value is 677.

The r-value of the linear regression that fits these data is approximately -0.94719. The correct answer is option A.

To find the r-value of the linear regression that fits the given data, we need to calculate the correlation coefficient. The correlation coefficient, also known as the Pearson correlation coefficient, measures the strength and direction of the linear relationship between two variables.

First, we calculate the mean (average) of the x-values (days) and the y-values (closing prices):

mean(x) = (1 + 2 + 3 + 4 + 5) / 5 = 3

mean(y) = (472.084 + 454.264 + 444.954 + 439.494 + 436.55) / 5 = 449.6704

Next, we calculate the deviations from the mean for both x and y:

x-deviation = (1 - 3, 2 - 3, 3 - 3, 4 - 3, 5 - 3) = (-2, -1, 0, 1, 2)

y-deviation = (472.084 - 449.6704, 454.264 - 449.6704, 444.954 - 449.6704, 439.494 - 449.6704, 436.55 - 449.6704) = (22.4136, 4.5936, -4.7164, -10.1764, -13.1204)

We calculate the sum of the products of the deviations:

\(\sum(x-deviation \times y-deviation) = (-2 \times 22.4136) + (-1 \times 4.5936) + (0 \times -4.7164) + (1 \times -10.1764) + (2\times -13.1204) = -80.6744\)

Next, we calculate the square root of the sum of the squares of the deviations for both x and y:

\(\sqrt(\sum(x-deviation)^2) = \sqrt((-2)^2 + (-1)^2 + 0^2 + 1^2 + 2^2) = \sqrt(4 + 1 + 0 + 1 + 4) = \sqrt10\sqrt(\sum(y-deviation)^2) = \sqrt(22.4136^2 + 4.5936^2 + (-4.7164)^2 + (-10.1764)^2 + (-13.1204)^2) = \sqrt(501.5114296 + 21.1240896 + 22.1985696 + 103.5532496 + 171.7240144) = \sqrt820.1113528 = 28.649\)

Finally, we calculate the correlation coefficient (r-value):

\(r-value = \sum(x-deviation \times y-deviation) / (\sqrt(\sum(x-deviation)^2) \times \sqrt(\sum(y-deviation)^2)) = -80.6744 / (√10 \times 28.649) = -0.94719\)

Option A.

The particular solution to the differential equation dy/dx = \(-2x/y^2\) with the initial condition f(3) = -3 is y = f(x) = \((-3x^2)^{(1/3)}.\)

To find the particular solution of the differential equation dy/dx = \(-2x/y^2\) with the initial condition f(3) = -3, we need to use separation of variables method.

First, we can rewrite the equation as \(y^2dy\) = -2xdx.

Next, we can integrate both sides: ∫\(y^2dy\) = -∫2xdx.

This gives us the equation \((1/3)y^3 = -x^2 + C\), where C is the constant of integration.

To find the value of C, we can use the initial condition f(3) = -3. Substituting x = 3 and y = -3, we get:

\((1/3)(-3)^3 = -(3)^2 + C\)

-9 = -9 + C

C = 0

Therefore, the particular solution to the differential equation dy/dx = \(-2x/y^2\) with the initial condition f(3) = -3 is given by:

\((1/3)y^3 = -x^2\)

\(y^3 = -3x^2\)

\(y = (-3x^2)^{(1/3)\)

So, the particular solution is y = f(x) = \((-3x^2)^{(1/3)}.\)

The amount in William's account after 3 years, with a $7000 initial investment and a 4.5% interest rate compounded annually, would be approximately $7956.33.

William initially invested $7000 in an account that earns 4.5% interest, compounded annually. To calculate the amount in the account after 3 years, we can use the compound interest formula:

A(t) = P(1 + i)^t

Where:

A(t) represents the amount in the account after time t,

P is the principal amount (initial investment),

i is the interest rate expressed as a decimal, and

t is the number of years.

Substituting the given values into the formula, we have:

P = $7000

i = 4.5% = 0.045 (decimal form)

t = 3 years

A(3) = $7000(1 + 0.045)^3

Simplifying the equation:

A(3) = $7000(1.045)^3

Evaluating the expression:

A(3) = $7000(1.13947625)

A(3) ≈ $7956.33

Therefore, after 3 years, William would have approximately $7956.33 in the account.

In summary, the amount in William's account after 3 years, with a $7000 initial investment and a 4.5% interest rate compounded annually, would be approximately $7956.33.

Ms. Bell's mathematics class consists of 6 sophomores, 11 juniors, and 13 seniors. The task is to determine the number of different ways Ms. Bell can create a 5-member committee of seniors, with each senior having an equal chance of being selected.

To solve this problem, we can use combinations. The number of ways to select a committee of 5 seniors from a group of 13 can be calculated using the combination formula:

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

Where n represents the total number of elements (seniors in this case), and k represents the number of elements to be selected (5 in this case). The exclamation mark denotes the factorial of a number.

Using the combination formula, the number of ways to select a 5-member committee from 13 seniors is:

C(13, 5) = 13! / (5!(13 - 5)!) = 13! / (5! * 8!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287

There is no requirement for supplemental oxygen.

All 20 occupants can fly without oxygen supply.

As the altitude increases, the atmospheric pressure decreases, which in turn reduces the partial pressure of oxygen in the air. This reduction in oxygen availability can cause hypoxia, which can lead to impaired judgment, vision, and coordination, and can be fatal in extreme cases.

The calculation of oxygen requirements can involve estimating the total oxygen consumption based on the number of occupants, their age, and their physical condition, and then determining the appropriate type and quantity of oxygen delivery systems to be carried on board the aircraft.

Here we have

An unpressurized aircraft with 20 occupants other than the pilots will be cruising at 14,000 feet msl for 25 minutes.

According to the Federal Aviation Regulations, if an aircraft is flying at an altitude above 12,500 feet MSL for more than 30 minutes,

then oxygen must be supplied to the occupants if:

The cabin pressure altitude exceeds 14,000 feet MSL, or

The cabin pressure altitude exceeds 15,000 feet MSL for any period of time.

In this case, the aircraft is flying at 14,000 feet MSL for 25 minutes, which is less than 30 minutes.
