Answer:

To find the length of q, we can use the Law of Cosines formula:

q = sqrt(p^2 + o^2 - 2 * p * o * cos(Q))

where p and o are the lengths of sides PQ and PO, and Q is the measure of the included angle between them.

Since we know that p = 9.7 inches and ∠Q = 93°, we can use the Law of Sines to find o:

sin(Q) = o/q

=> o = q * sin(Q)

=> o = 9.7 * sin(93)

Using this formula and rounding to the nearest tenth, we can find that o = 11.7 inches.

Now we can use the Law of Cosines to find q:

q = sqrt(p^2 + o^2 - 2 * p * o * cos(Q))

=> q = sqrt(9.7^2 + 11.7^2 - 2 * 9.7 * 11.7 * cos(93))

Rounding to the nearest tenth, we get that q = 17.2 inches.

The probability that the machine is up at times n = 5, 10, 15, and 20 can be calculated as n = 5: 0.773797, n = 10: 0.60653065, n = 15: 0.47000363 and n = 20: 0.35831814.

For the machine described in Conceptual Problem 2.8, the probability that the machine is up at times n = 5, 10, 15, and 20 can be calculated using the formula:

P(machine is up at time n) = P(machine was up at time n-1) * p

Given that the machine is initially up and p = 0.95, the probabilities are as follows:

Answer:

(3, 1 )

Step-by-step explanation:

x = 3y → (1)

2x + 4y = 10 → (2)

substitute x = 3y into (2)

2(3y) + 4y = 10

6y + 4y = 10

10y = 10 ( divide both sides by 10 )

y = 1

substitute y = 1 into (1)

x = 3y = 3(1) = 3

solution is (3, 1 )

Answer:

(d - 4)² - 7

Step-by-step explanation:

Formula for completing the square: x² + ax + b = (x + [tex]\frac{a}{2}[/tex])² - ([tex]\frac{a}{2}[/tex])² + b

d² - 8d + 9 = (d - [tex]\frac{8}{2}[/tex])² - ([tex]\frac{8}{2}[/tex])² + 9

                  = (d - 4)² - 4² + 9

                  = (d - 4)² - 16 + 9

                  = (d - 4)² - 7

Answer: 1 quarter or 0.25 cents.

Step-by-step explanation: According to the illustration shown, we can infer that the coin we are looking for is for 1 value. So, if we subtract the amount shown (total) from the other coins (pennies in this case), 0.27 - 0.02 = 0.25 which is equivalent to the coin of the quarter (worth $0.25 USD) So, the blanks would look like this:

The radius of each of the sphere is 1.1 centimetres.

Fifteen solid spheres are made by melting a solid metallic cone of base diameter 2cm and height 15cm. Therefore, let's find the volume of the cone to know the radius of the sphere.

Hence,

volume of a cone = 1 / 3 πr²h

where

Therefore,

volume of the cone = 1 / 3 × π × 1² × 15

volume of the cone = 5π cm³

Therefore, let's find the radius of the sphere.

volume of a sphere = 4πr³

where

5π = 4 × π × r³

r³ = 5 / 4

r = ∛5 / 4

r = 1.07721734502

Here the population growth is as per the Malthusian model. As per the calculations, the bacterial population will reach 10000 after 33 days.

Here the bacterial growth is as per the exponential growth curve. So the equation is,

   [tex]P_{t} = P_{0} e^{rt}[/tex]

[tex]P_{t}[/tex] is the population at n

[tex]P_{0}[/tex] is the initial population

r is the time

t is the rate

Population doubles after 10 days.

So,  [tex]2000 = 1000e^{r*10} \\\\\frac{2000}{1000} = e^{10r}\\\\ 2 = e^{10r\\}\\\\[/tex]

Taking logarithms on both sides

[tex]ln(2) = lne^{10r}\\\\10r = 0.693\\ \\r = 0.0693[/tex]

So the rate is 0.0693.

When population reaches 10000,

[tex]10000 =1000e^{0.0693t}[/tex]

[tex]\frac{10000}{1000} =e^{0.0693n}[/tex]

The slope of FG is equal to 1/5 while the slope of HJ is equal to -2.

Lines FG and HJ are neither parallel nor perpendicular because their slopes are different and not an inverse of each other.

In Mathematics, the slope of any straight line can be determined by using this mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

For the slope of line FG, we have the following:

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (2 - 1)/(8 - 3)

Slope (m) of line FG = 1/5.

For the slope of line HJ, we have the following:

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (6 - 4)/(1 - 2)

Slope (m) of line HJ = -2/1.

The inverse function is the reverse of the original function and relationship between the two functions is determined by the mapping between the inputs and outputs of the original function.

In mathematics, the inverse function is a inverse function of a function is the reverse of the original function.

To understand the relationship between an inverse function and its original function, consider the following example. Suppose we have a function that maps the height of an object to its weight.

The original function would take the height as an input and output the corresponding weight. The inverse function, on the other hand, would take the weight as an input and output the corresponding height.

It is important to note that not all functions have an inverse. A function is only considered to have an inverse if it is a one-to-one mapping, meaning that each input has a unique output.

In summary, If the original function is a one-to-one mapping, then it has an inverse function that can be found by swapping the inputs and outputs.

The IH states that the sum of the angles in convex polygon C(which, by the IH, is (n - 2)·π) and the sum of the angles in triangle B (180°) is the same as the sum of the angles in A.

Using induction all convex polygons with n vertices have angles that add to (n - 2)·π, therefore let P(n) be that. We will demonstrate that P(n), where n≥3, holds for every n ∈ N. We demonstrate P(3), which states that any convex polygon with three vertices has an angle total of 180 degrees. Any triangle formed by such a polygon has angles that add up to 180°.

Assume that P(n) holds for some n ≥ 3 and that all convex polygons with n vertices have angles that add to (n-2) 180° for the inductive step. We demonstrate P(n+1), which states that each convex polygon with n+1 vertices has an angle sum of (n-1)·π. Let A represent any n+1-vertex convex polygon.

The IH states that the sum of the angles in convex polygon C (which, by the IH, is (n - 2)·π) and the sum of the angles in triangle B (180°) is the same as the sum of the angles in A. As a result, the total angle in A is (n-1) 180°. Thus, the induction is complete and P(n + 1) holds.

Answer:

To prove that triangle TUW is isosceles, we can use the fact that ray TV bisects angle ZUT and is an altitude in triangle TUW.

Since ray TV bisects angle ZUT, it splits the angle into two congruent angles, ZTV and TVU. This means that angle ZTV is congruent to angle TVU.

Since ray TV is an altitude in triangle TUW, it forms a right angle with the base of the triangle, which is line segment TU. This means that angle TVU is a right angle, and therefore, angle ZTV is a right angle as well.

Since angle ZTV and angle TVU are congruent right angles, we know that the two sides that form these angles, UT and TU, are congruent. This means that side UT is congruent to side TU, and therefore, triangle TUW is isosceles.

The initial value problem [tex](9ye^9xy-5/y)dx (9xe^9xy 5x/y^2)dy=0, y(3)=3[/tex] can be approximated using numerical methods such as the Euler method.

To find the initial value problem is a differential equation of the form:

[tex](9ye^(9xy) - 5/y) dx + (9xe^(9xy) - 5x/y^2) dy = 0[/tex]

with the initial condition y(3) = 3.

Since this is an implicit solution, we cannot find an explicit solution for y in terms of x. However, we can use numerical methods to find approximate solutions for y. One such method is the Euler method.

In the Euler method, we start with an initial estimate for y(x), and then use the derivative information to find y(x + h), where h is a small step size. We then use the new estimate to find the next value, and so on.

To apply the Euler method to this problem, we start with the initial condition y(3) = 3, and then use the following formula to estimate y(x + h):

y(x + h) = y(x) + h * f(x, y(x))

where f(x, y) is the derivative information from the differential equation:

[tex]f(x, y) = -(9xe^(9xy) - 5x/y^2) / (9ye^(9xy) - 5/y)[/tex]

Using the Euler method, we can iteratively estimate y(x) for increasing values of x, until we reach a desired value of x or the accuracy is within an acceptable limit.
