By using Python, you will come up with your own challenging algorithm for other students to trace.

If a certain is true, the if/else expression triggers a sequence of instructions to run. Another piece of code may be run if the condition is false.

The if/else statement is a component of Python's "Conditional" Statements, which are used to carry out various operations based on various circumstances.

These conditional statements are available in Python:

If you want a block of code to run only if a certain condition is true, use the if statement.

If the same expression is false, use instead that to provide a set of instructions that should be run.

If the first expression is false, can use else if sentence to establish a comprehensive criterion to test.

To choose which of the several program code should be performed, use the switch.

We'll assume the quadratic equation has real coefficients

Answer:

The other solution is x=1-8i.

Step-by-step explanation:

The Complex Conjugate Root Theorem

if P(x) is a polynomial in x with real coefficients, and a + bi is a root of P(x) with a and b real numbers, then its complex conjugate a − bi is also a root of P(x).

The question does not specify if the quadratic equation has real coefficients, but we will assume that.

Given x=1+8i is one solution of the equation, the complex conjugate root theorem guarantees that the other solution must be x=1-8i.

Answer:

the answer would be x= 1-8i

4(a+2)=8+4a

Step 1: Simplify both sides of the equation.

4(a+2)=8+4a

(4)(a)+(4)(2)=8+4a(Distribute)

4a+8=8+4a

4a+8=4a+8

Step 2: Subtract 4a from both sides.

A compound statement is a group of two or more statements connected using words such as 'or', 'and', 'if then', 'if and only if'.

Then, we have:

This is a compound statement of conditional type where the first simple statement is the condition for the second simple statement.

Then, we have:

p: The dog is hungry.

q: She is barking.

p→q: The dog is hungry if she is barking.

Thus, this statement is a compound statement of conditional type.

We can see this statement as a conjunction of two simple statements:

• p: Bill reads books.

• q: Bill reads magazines.

Then, we have:

p ∧ q: Bill reads books and magazines.

Thus, this statement is a compound statement of conjunction type.

We can see this statement as a conjunction of two simple statements:

Answer:

Step-by-step explanation:

Penelope has, 52quarters, 104 dimes, 416 nickels, and 162 pennies.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

From the given information let, 'x' be the number of quarters,

Therefore, Dimes is 2x, Nickels is 8x and Pennies is 3x.

So, x + 2x + 8x + 4x = 780.

15x = 780.

x = 52, The number of quarters.

2×52 = 104, The number of Dimes.

8×52 = 416 Nickels.

3×52 = 162 Pennies.

Answer:

Jenny had 9 incorrect answers.

Step-by-step explanation:

We know that Jenny earned 104 of a possible 140 points on a test.

140 - 104 = 36

We also know that she lost 4 points for every incorrect answer.

36 ÷ 4 = 9

Therefore, Jenny had 9 incorrect answers.

Hope this helps! :D

Answer:

9 questions incorrect

Step-by-step explanation:

Make an Equation

104+x(4)=140

X is for incorrect answers and since each incorrect answer is Worth 4, multiply x by 4. The 104 is the point Jenny orignally got so we put that in the equation to find how many Incorrect she got.

Solve the equation

104+4x=140 Subtract 104 on both sides

4x=36   Divide 4 on both sides

x=9   X=9

Rational numbers

Step-by-step explanation:

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1.

Answer:

Step-by-step explanation:

1) to find the equation of the given line (its slop-interception form is y=mx+i, where m - slop, i - interception):

a) y=2x+i, where m=2;

b) it is possible to calculate the value of 'i' after the substitution the point (5;-3) into the equation y=2x+i:

-3=2*5+i; ⇒ i= -13;

c) the equation of the given line is y=2x-13.

2) to calculate the value of 'R':

if to substitute the point (-12;R) into the equation y=2x-13, then

R=2*(-12)-13; ⇒ R= -37.

A relation is a set of ordered pairs, while a function is a relation in which each input has only one output.

Hence, to create a relation that is also a function, we must guarantee that each x-coordinate is matched with only one y-coordinate. As a result, the three coordinates that form a relation that is also a function are:(1, 4), (2, 6), and (3, 9). Notice that for each of the x-coordinates 1, 2, and 3, there is only one y-coordinate. There are no two distinct y-coordinates that correspond to the same x-coordinate.

Thus, each of these three coordinates satisfy the definition of a function.

(x - 10)² + (y + 4)² = 121

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (10, - 4 ) and r = 11 , then

(x - 10)² + (y - (- 4) )² = 11² , that is

(x - 10)² + (y + 4)² = 121

The requirements for a hypothesis test are satisfied.

To test the claim that the rate of polio is less for children given the Salk vaccine, we need to check if the requirements for a hypothesis test about two population proportions are met. The requirements are:

1. The samples are simple random samples and independent.
2. For each of the two groups, the sample size is at least 1000.

In this case, the study involved 401,974 children who were randomly assigned to two groups: the treatment group with 201,229 children and the placebo group with 200,745 children. This satisfies the first requirement, as the samples are simple random samples and independent. The sample size for both groups is also larger than 1000, meeting the second requirement.

Therefore, the requirements for a hypothesis test are satisfied, and we can proceed with testing the claim that the rate of polio is less for children given the Salk vaccine.

To find the derivative of the curve given by the equation ry + sin(y)cos(x) = y², where r is a constant, we can use implicit differentiation.

Differentiating both sides of the equation with respect to x, we get: r(dy/dx) + (d/dx)(sin(y)cos(x)) = 2yy'(dy/dx). Applying the chain rule, we have: r(dy/dx) - sin(y)sin(x) - cos(y)cos(x)(dy/dx) = 2yy'(dy/dx). Rearranging the terms and factoring out dy/dx, we get: (dy/dx)(r - cos(y)cos(x)) = sin(y)sin(x) - 2yy'(dy/dx). Dividing both sides by (r - cos(y)cos(x)), we obtain the expression for the derivative: dy/dx = (sin(y)sin(x) - 2yy'(dy/dx))/(r - cos(y)cos(x)). Simplifying further, we can isolate dy/dx: dy/dx = (sin(y)sin(x))/(r - cos(y)cos(x)) - (2yy'(dy/dx))/(r - cos(y)cos(x)).

b) To find the equation of the tangent line to the curve that passes through a given point (x₀, y₀), we need to substitute the coordinates of the point into the derivative expression we obtained above. Let's assume the point is (x₀, y₀). Therefore, we have: dy/dx = (sin(y₀)sin(x₀))/(r - cos(y₀)cos(x₀)) - (2y₀y'(dy/dx))/(r - cos(y₀)cos(x₀)). Next, we substitute the values of x₀ and y₀ into the expression for dy/dx and solve for dy/dx: dy/dx = (sin(y₀)sin(x₀))/(r - cos(y₀)cos(x₀)) - (2y₀y'(dy/dx))/(r - cos(y₀)cos(x₀)).

Now, we can rearrange this equation to solve for dy/dx: (dy/dx)[1 + (2y₀)/(r - cos(y₀)cos(x₀))] = (sin(y₀)sin(x₀))/(r - cos(y₀)cos(x₀)). Finally, we can isolate dy/dx by dividing both sides: dy/dx = (sin(y₀)sin(x₀))/(r - cos(y₀)cos(x₀))[1 + (2y₀)/(r - cos(y₀)cos(x₀))]. This expression gives the value of the derivative dy/dx at the point (x₀, y₀), which represents the slope of the tangent line to the curve at that point.

True. A hashing algorithm is a mathematical routine used to generate a hash value from a primary key value.

A relative record number that may be used to retrieve the required record in a data structure is created using this hash value.

In order to facilitate quick access to the data, the hashing algorithm makes sure that the same hash value is generated for every primary key. How quickly the requested record can be found depends on how effective the hashing method is.

Also, it must be safe enough to prevent two main key values from producing the same hash value, as doing so might result in accessing the wrong records.

Two equilateral triangles.

One isosceles triangle.

We see that,

Both equilateral triangles have the same sides and the same angles.

5x - 1 = 24

5x = 24 + 1

5x = 25

x = 5

We see that,

Let the opposite angle of 6y° = m

6y° + 60 + 60 + m = 360

6y + 120 = 360
