The number of address bits required if memory is comprised of n chips and m words per chip is log₂ (n.m). Option B, log₂ (n.m), is the correct answer.
Each memory unit has multiple chips, each of which stores data in multiple words. As a result, the overall number of words increases. The address bus size is determined by the number of memory locations (or words) available. When each chip has m words, the total number of memory locations will be n x m.
We may use the binary logarithm to get the number of address bits needed to address these locations, which is log₂ (n.m). Therefore, the correct answer is option B, log₂ (n.m).

Let \( P(x, y) \) denote the point where the terminal side of an angle \( \theta \) meets the unit circle. If \( P \) is in Quadrant II and \( y=\frac{15}{17} \), find \( \cot (\theta)+\csc (\theta) \
According to the given information, the answer is \(\(\frac{17-2\sqrt{34}}{15}\)\) and the problem is solved.
Let (P(x,y) denote the point where the terminal side of an angle \(\theta\) meets the unit circle, and we know that P is in quadrant II and \(\(y = 15/17.\)\)
Suppose we draw a unit circle, and label the quadrant II with the coordinates (-x, y).
[See the diagram below].
Labeling the horizontal line segment with length \(x\) (also known as the adjacent side), we can use the Pythagorean theorem to find the length of the vertical line segment (also known as the opposite side):
\(\begin{aligned} x^2 + y^2 &= 1^2 \\ x^2 &= 1^2 - y^2= 1 - \left(\frac{15}{17}\right)^2 \\ x^2 &= \frac{17^2 - 15^2}{17^2} = \frac{136}{289} \\ x &= \pm\frac{2\sqrt{34}}{17}. \end{aligned}\)
Since \(P\) is in quadrant II, we have \(x < 0\), so we take the negative value, that is, \(\(x = -\frac{2\sqrt{34}}{17}.\)\)
Then,\(\[\cot \theta = \frac{x}{y} \\= \frac{-2\sqrt{34}/17}{15/17} \\= -\frac{2\sqrt{34}}{15},\]\) and \(\[\csc \theta = \frac{1}{y} \\= \frac{17}{15}.\]\)
Therefore, \(\[\cot \theta + \csc \theta = -\frac{2\sqrt{34}}{15} + \frac{17}{15} \\= \frac{17 - 2\sqrt{34}}{15}.\]\)
The answer is \(\(\frac{17-2\sqrt{34}}{15}\)\) and the problem is solved.

*and if one number doesent have a decimal just add one at the end of the number and zeros after the decimal so you can line them up and add them like the way above.*
Answer:
Adding whole numbers together is fairly straightforward, but how do we add a whole number and a number with a decimal? The trick is to write the whole number as a decimal number by including a decimal point followed by zeros. Use as many zeros as needed to make your whole number have the same number of decimal places as the decimal number. Then, align the decimal points and add the numbers by adding their respective place value digits together.

Answer: $3.64
Step-by-step explanation:
At the store, you buy four toys for $1.5, which means you pay $1.5 * 4, or $6.
Then, you calculate the sales tax, which is 6%, which means you multiply $6 by (100% + 6%), or $6*(1.06) which is $6.36.
Finally, if you hand the cashier $10, and you spent $6.36, your change is $10 - $6.36, which is $3.64.
Given: r = 3 + 6 sin(θ)
Part a: Graph the polar curve.
Part b: Give the formula involving one or more integrals for the area inside the inner loop for the polar curve. Do not evaluate the integral.
Part c: Give the formula for the length of the outer loop for the polar curve. Do not evaluate the integral.
(a) The polar curve is a cardioid. (b) The inner loop can be expressed as 1/2 times the integral of (r^2) dθ from θ = -π/6 to θ = π/6. (c) The formula for the length of the outer loop can be expressed as the integral of the square root of (r^2 + (dr/dθ)^2) dθ from θ = -π/3 to θ = π/3.
(a) The given polar equation r = 3 + 6sin(θ) represents a cardioid. A cardioid is a heart-shaped curve, and in this case, the center of the cardioid is at (3, 0).
(b) To find the formula for the area inside the inner loop, we can use the formula for the area bounded by a polar curve, which is 1/2 times the integral of (r^2) dθ over the desired interval. In this case, the interval is from θ = -π/6 to θ = π/6. Thus, the formula for the area inside the inner loop is 1/2 times the integral of (3 + 6sin(θ))^2 dθ from θ = -π/6 to θ = π/6.
(c) The length of the outer loop can be found using the arc length formula for polar curves. The formula is the integral of the square root of (r^2 + (dr/dθ)^2) dθ over the desired interval. In this case, the interval is from θ = -π/3 to θ = π/3. Therefore, the formula for the length of the outer loop is the integral of the square root of (3 + 6sin(θ))^2 + (6cos(θ))^2 dθ from θ = -π/3 to θ = π/3.

(b) How many hours of television viewing must a household have in order to be in the top 3% of all television viewing households? (Round your answer to two decimal places.) (c) What is the probability that a household views television more than 3 hours a day? (Round your answer to four decimal places.)
The probability that a household watches more than 3 hours of television a day is 0.0478.
The mean daily viewing time of television is 8 hours per household. Use a normal probability distribution with a standard deviation of 3 hours to answer the following questions about daily television viewing per household.
(a) Probability that a household views television between 5 and 11 hours a day:P(5 < x < 11) = P(z < (11-8)/3) - P(z < (5-8)/3) = P(z < 1) - P(z < -1) = 0.8413 - 0.1587 = 0.6826(b) Hours of television viewing must a household have in order to be in the top 3% of all television viewing households:
The top 3% of all households correspond to z = 1.88. Therefore, the number of hours that a household must watch television to be in the top 3% is:1.88 = (x - 8) / 3x - 8 = 5.64x = 13.64
(c) Probability that a household views television more than 3 hours a day:P(x > 3) = P(z < (3-8)/3) = P(z < -5/3) = 0.0478.the probability that a household watches more than 3 hours of television a day is 0.0478.

AB and YX are corresponding sides, BC and XZ are corresponding sides, and AC and YZ are corresponding sides of given triangle.
What is triangle?
A triangle is a two-dimensional geometric shape that has three sides, three angles, and three vertices. It is one of the simplest polygonal shapes and is commonly studied in geometry.
Since we have:
∠A ≅ ∠Y
∠B ≅ ∠X
∠C ≅ ∠Z
We can conclude that the two triangles ABC and XYZ are similar by the Angle-Angle (AA) similarity theorem.
Therefore, the corresponding sides of the two triangles are proportional to each other. We can write this as:
AB : YX = BC : XZ = AC : YZ
where AB and YX are corresponding sides, BC and XZ are corresponding sides, and AC and YZ are corresponding sides.
In other words, the ratio of the length of each side in triangle ABC to the corresponding side in triangle XYZ is constant.

Consider the following non homogeneous differental equation with constant and the parameters 2, 2, 8, σ and p. coefficients at rt = - y" (t) + ay" (t) + by!" (t) + Cy' (t) + dy(t) 3 e + t² (cos (at)
The given non-homogeneous differential equation can be written as:
- y''(t) + a*y'(t) + b*y(t) + c*y'(t) + d*y(t) = 3*e^t + t^2*cos(at)
To solve this differential equation, we first consider the corresponding homogeneous equation:
- y''(t) + a*y'(t) + b*y(t) + c*y'(t) + d*y(t) = 0
The solutions to the homogeneous equation can be found by assuming a solution of the form y(t) = e^(rt). Substituting this into the equation gives the characteristic equation:
r^2 + (a+c)*r + (b+d) = 0
The roots of the characteristic equation can be found using the quadratic formula:
r = (-b-c ± sqrt((a+c)^2 - 4(b+d))) / 2
Let the roots be denoted as r1 and r2.
If the roots are real and distinct (r1 ≠ r2), then the general solution to the homogeneous equation is:
y(t) = A*e^(r1*t) + B*e^(r2*t)
where A and B are constants determined by initial conditions.
Next, we find a particular solution to the non-homogeneous equation. Since the right-hand side contains terms of the form e^t and t^2*cos(at), we can assume a particular solution of the form:
y_p(t) = Ae^t + B*t^2*cos(at) + C*t^2*sin(at)
where A, B, and C are constants to be determined.
Substituting this particular solution into the non-homogeneous equation, we can solve for the values of A, B, and C.
Once the particular solution is found, the general solution to the non-homogeneous equation is given by the sum of the general solution to the homogeneous equation and the particular solution:
y(t) = y_h(t) + y_p(t)
where y_h(t) represents the general solution to the homogeneous equation and y_p(t) represents the particular solution to the non-homogeneous equation.
To solve the given non-homogeneous differential equation, we need to find the roots of the characteristic equation and determine the general solution to the homogeneous equation. Then, we find a particular solution by assuming a form that matches the right-hand side of the equation and solve for the constants. Finally, the general solution is obtained by adding the general solution to the homogeneous equation and the particular solution.

Arithmetic expressions can be used as control expressions in programming languages when a control structure, such as an if statement or a loop, expects a condition to determine the flow of execution
Arithmetic expressions can be used as control expressions in certain programming languages or contexts where a control structure expects a conditional expression to determine the flow of execution.
Typically, control expressions are used in decision-making structures such as if statements, while loops, for loops, and switch statements.
In most programming languages, the control expression must evaluate to a boolean value (true or false) in order to determine the execution path. However, some languages allow arithmetic expressions to be used in control structures, considering a value of zero as false and any non-zero value as true.
