The hypotenuse of the given triangle is 8√2 units.

In accordance with the Pythagorean theorem, the square of the length of the hypotenuse (the side that faces the right angle) in a right triangle equals the sum of the squares of the lengths of the other two sides. If you know the lengths of the other two sides of a right triangle, you may apply this theorem to determine the length of the third side. By examining whether the sides of a triangle satisfy the Pythagorean equation, it can also be used to assess whether a triangle is a right triangle. Pythagoras, an ancient Greek mathematician, is credited with discovering the theorem, therefore it bears his name.

The third side of the triangle can be determined using the Pythagoras Theorem as follows:

c² = 8² + 8²

c² = 2(8²)

c = 8√2

Hence, the hypotenuse of the given triangle is 8√2 units.

The three critical points of the function f(x, y) = (x² + y²)y² - x² are (0, 0), (0, -1), and (0, 1). The point (0, 0) is a saddle point, while (0, -1) is a local maximum and (0, 1) is a local minimum.

To find the critical points, first compute the partial derivatives fx and fy, then set them to zero and solve for x and y. fx = -2x(1+y²) and fy = 2y(3y²+x²).

Solving fx=0 and fy=0 simultaneously, we get (0, 0), (0, -1), and (0, 1) as critical points.

To determine the nature of each critical point, compute the second-order partial derivatives fx, fyy, and fxy, and then find the determinant of the Hessian matrix, D = fx * fyy - fxy². For (0, 0), D < 0, making it a saddle point.

Therefore, Don's car would use 67.035 L of gas to travel 735 km.

Cross multiplication is a method used to compare the relative sizes of two fractions. To cross-multiply two fractions, you multiply the numerator of one fraction by the denominator of the other fraction, and then do the same with the other numerator and denominator, putting the two products equal to each other. For example, if you have the fractions 2/3 and 3/4, you can cross-multiply as follows:

[tex]2/3 = x/4[/tex]

[tex]2 x 4 = 3 x x[/tex]

[tex]8 = 3x[/tex]

[tex]x = 8/3[/tex]

So, the two fractions are equivalent, and both are equal to 8/3. Cross-multiplication can also be used to solve equations that involve fractions, by isolating the variable on one side of the equation.

To find out how much gas Don's car would use to travel 735 km, we can use the fact that the car uses 9.1 L of gas every 100 km. We can set up a proportion to solve for the amount of gas used:

9.1 L / 100 km = x L / 735 km

To solve for x, we can cross-multiply and simplify:

[tex]9.1 L * 735 km = 100 km * x L[/tex]

[tex]6703.5 Lkm = 100 km * x L[/tex]

[tex]6703.5 Lkm / 100 km = x L[/tex]

In linear algebra, matrix addition and scalar multiplication are fundamental operations that are used to manipulate matrices.

The set of all 2x2 invertible matrices can be expressed using standard matrix addition and scalar multiplication. An invertible matrix is one that has a non-zero determinant. For a 2x2 matrix A, with elements a, b, c, and d:
A = | a  b |
     | c  d |
The determinant of A is calculated as: det(A) = ad - bc. To be invertible, det(A) ≠ 0.
Standard matrix addition is the element-wise addition of two matrices of the same dimensions. If we have another 2x2 matrix B:
B = | e  f |
     | g  h |
The standard matrix addition of A and B is:
A + B = | a+e  b+f |
           | c+g  d+h |
Scalar multiplication involves multiplying every element of a matrix by a scalar value. If we have a scalar k, the scalar multiplication of matrix A is:
kA = | ka  kb |

Bowling Suppose that Ralph gets a strike when bowling 30% of the time. The probability that Ralph gets a turkey, but fails to get a clover (four strikes in a row) is 1.89%.

To find the probability that Ralph gets a turkey (three strikes in a row) but fails to get a clover (four strikes in a row), we need to first calculate the probability of getting a clover.
Assuming that Ralph's chance of getting a strike on any given roll is independent of his previous rolls, the probability of getting a clover is simply the probability of getting four strikes in a row, which is:
[tex]0.3^4[/tex] = 0.0081 or 0.81%
Now, to find the probability of getting a turkey but failing to get a clover, we can use the formula:
P(turkey and no clover) = P(turkey) - P(clover and turkey)
P(turkey) = the probability of getting three strikes in a row, which is:
[tex]0.3^3[/tex] = 0.027 or 2.7%
P(clover and turkey) = the probability of getting four strikes in a row (i.e. a clover), which we already calculated to be 0.81%.
Therefore,
P(turkey and no clover) = 2.7% - 0.81% = 1.89%
So, the probability that Ralph gets a turkey but fails to get a clover is 1.89%.

Okay, here are the steps:

* Hassam buys 2 adult tickets and 2 child tickets

* Let's assume:

** Adult ticket price = $50

** Child ticket price = $25

* So total ticket price = 2 * $50 + 2 * $25 = $200

* The booking fee is 5% of the total cost

* 5% of $200 is $10

* So total payment = $200 + $10 = $210

Therefore, the total Hassam pays altogether is $210

The probability of having a travel credit card is 0.5 is about 66.76 million lira or 33,380 euros.

(a) The estimated model equation is:

log(p/1-p) = -3.5561 + 0.0532*income

where p is the probability of having a travel credit card.

(b) The sign of ß (0.0532) is positive, which means that there is a positive relationship between income and the probability of having a travel credit card. As income increases, the probability of having a travel credit card also increases.

(c) To find the income level at which the probability of having a travel credit card is 0.5, we can set p = 0.5 in the model equation and solve for income:

log(0.5/1-0.5) = -3.5561 + 0.0532*income

0 = -3.5561 + 0.0532*income

income = 3.5561/0.0532

income = 66.76

Therefore, according to the estimated model equation, the income level at which the probability of having a travel credit card is 0.5 is about 66.76 million lira or 33,380 euros.
(a) The estimated model equation is given by:

log(p / (1 - p)) = -3.5561 + 0.0532 * Income

where p is the probability of having a travel credit card and Income is the annual income in millions of lira.

(b) The sign of ß (the coefficient of Income) is positive, which indicates that as the annual income increases, the probability of having a travel credit card also increases.

(c) To find the income level where the probability is 0.5, we need to solve the equation:

log(0.5 / (1 - 0.5)) = -3.5561 + 0.0532 * Income

0 = -3.5561 + 0.0532 * Income

Income = 3.5561 / 0.0532 ≈ 66.86 million lira

So, the probability of having a travel credit card is 0.5 when the annual income is approximately 66.86 million lira.

(b) The number of binary strings of length 10 with at least one 1 and at least one 0 is 2045.

(a) To count the number of binary strings of length 10 with at least one 1, we can subtract the number of strings with all 0's from the total number of binary strings of length 10.

The total number of binary strings of length 10 is 2^10 = 1024, and the number of strings with all 0's is 1 (namely, 0000000000). Therefore, the number of binary strings of length 10 with at least one 1 is:

1024 - 1 = 1023

(b) To count the number of binary strings of length 10 with at least one 1 and at least one 0, we can use the principle of inclusion-exclusion.

The number of strings with at least one 1 is 1023 (as we calculated in part (a)), and the number of strings with at least one 0 is also 1023 (since the complement of a string with at least one 0 is a string with all 1's, and we calculated the number of strings with all 0's in part (a)).

However, some strings have both no 0's and no 1's, so we need to subtract those from the total count. There is only one such string, namely 1111111111. Therefore, the number of binary strings of length 10 with at least one 1 and at least one 0 is:

To find the differential dy of the given function y = csc 9x, we can start by using the chain rule of differentiation, which states that the derivative of a composite function is the product of the derivative of the outer function and the derivative of the inner function.

The sine function has a reciprocal called the cosecant function. The cosecant function is the hypotenuse divided by the opposite side, just like the sine function is the opposite side divided by the hypotenuse. The hypotenuse and legs are terms for the two sides that are not the right angle.

dy/dx = dy/du * du/dx

We can find the derivative of y = csc u using the formula for the derivative of the cosecant function:

d/dx (csc x) = -csc x cot x

So we have:

dy/du = d/dx (csc u) = -csc u cot u

To find the derivative of the inner function, we can use the chain rule again:

du/dx = 9

Putting it all together, we have:

dy/dx = dy/du * du/dx = -csc u cot u * 9

Substituting u = 9x, we get:

dy/dx = -csc (9x) cot (9x) * 9

Therefore, the differential dy of y = csc 9x is:

The two lines are neither parallel nor perpendicular.

Parallel lines are two lines that are always the same distance apart and never intersect. In Euclidean geometry, parallel lines are denoted by an arrow symbol or by two vertical lines.

A perpendicular line is a line that intersects another line at a right angle (90 degrees).

To determine if the two lines 2x-7y=-14 and y=(-2/7)x-1 are parallel, perpendicular or neither, we need to compare their slopes.

The given equation 2x-7y=-14 can be rearranged into slope-intercept form:

2x - 7y = -14

-7y = -2x - 14

y = (2/7)x + 2

So the slope of the first line is 2/7.

The second equation y=(-2/7)x-1 is already in slope-intercept form, so the slope of the second line is -2/7.

If two lines have slopes that are the same, they are parallel. If the product of their slopes is -1, then they are perpendicular. Otherwise, they are neither parallel nor perpendicular.

In this case, the product of the slopes is:

(2/7) * (-2/7) = -4/49

Since the product of the slopes is not -1 and it is not equal to each other, the two lines are neither parallel nor perpendicular.

For n = 2, it takes exactly 1 step to assemble a 2-piece jigsaw puzzle, which satisfies the statement.

Inductive hypothesis, Assume that for some k > 1, it takes exactly k - 1 steps to assemble a k-piece jigsaw puzzle from start to finish. That is, the statement is true for all n = 2, 3, ..., k.

Inductive step, We need to show that the statement is also true for n = k + 1. To assemble a (k + 1)-piece jigsaw puzzle, we can first separate one piece from the puzzle. This leaves us with a k-piece puzzle. By the inductive hypothesis, it takes exactly k - 1 steps to assemble the k-piece puzzle. We can then attach the remaining piece to the completed k-piece puzzle, which takes 1 additional step. Therefore, it takes exactly (k - 1) + 1 = k steps to assemble a (k + 1)-piece jigsaw puzzle.

If the company made a profit of $112000, i first year operation, then the total profit made by the company in 26 years of operation is $8170286.

In order to find the profit after 26 years, we use the formula for "future-value" of investment with compound interest;

⇒ FV = PV × (1 + r)ⁿ,

where FV is = future value, PV is = present value, r is = interest rate per period, and n = time (in years),

In this case, the "present-value" is $112,000, the "interest-rate" per period is 18%, and time is 26 years.

We have to find the total profit, which is = "future-value" - "present-value",

⇒ Total profit = FV - PV,

Substituting the value,

We get,

⇒ FV = $112000 × (1 + 0.18)²⁶,

y'(0) = c1 + 2c2 + 2c3 = -8

y''(0) = c2 + 4c3 = 35

Solving these equations simultaneously, we get:

c1 = -35/2

c2 = 35/2

c3 = -9

So the final solution to the differential equation is:

[tex]y(x) = (-35/2) e^x + (35/2) e^{(2x) }- 9xe^{(2x)[/tex]
