Therefore, the answer is option C: theta = pi/2 and theta = 3pi/2.

To determine when tan(theta) is undefined on the unit circle, we need to remember the definition of the tangent function.
Tangent is defined as the ratio of the sine and cosine of an angle. Specifically, tan(theta) = sin(theta)/cos(theta).

Now, we know that cosine can never be equal to zero on the unit circle, since it represents the x-coordinate of a point on the circle and the circle never crosses the x-axis. Therefore, the only way for tan(theta) to be undefined is if the cosine of theta is equal to zero.
There are two values of theta on the unit circle where cosine is equal to zero: pi/2 and 3pi/2.

At theta = pi/2, we have cos(pi/2) = 0, which means that tan(pi/2) = sin(pi/2)/cos(pi/2) is undefined.
Similarly, at theta = 3pi/2, we have cos(3pi/2) = 0, which means that tan(3pi/2) = sin(3pi/2)/cos(3pi/2) is also undefined.
Therefore, the answer is option C: theta = pi/2 and theta = 3pi/2.

In order to find the values of a, b, c, and d that satisfy the given equation, let's break it down step by step. The equation is as follows: 4 - 103i = (a - bi)(c + di), where i represents the imaginary unit.

To find the values of a, b, c, and d, we can equate the real and imaginary parts on both sides of the equation separately. For the real part: 4 = ac + bd and for the imaginary part: -103 = ad - bc.

We can solve this system of equations using algebraic methods such as substitution or elimination. By doing so, we can find the values of a, b, c, and d that satisfy the equation.

The first paragraph summarizes the task of finding the values of a, b, c, and d that make the equation hold true. The second paragraph explains the approach of equating the real and imaginary parts separately and solving the resulting system of equations to determine the values of a, b, c, and d.

Answer:a i belive not 100% sure

Step-by-step explanation:

This question is very oddly worded.  The domain is the set of x-values, but this is a set of (x,y) ordered pairs.

I'm reading this question as "Here's a function, { (1,5), (2,1), (-1,-7) }.  If this is reflected over the x-axis, what's the range?"

Assuming that is the question that is meant to be asked, reflecting a function over the x-axis will just change the signs of the y-values.

    (1,5) -> (1,–5)

    (2,1) -> (2,–1)

    (-1,-7) -> (-1,+7)

I'd pick the third option.

By finding the unit rate, we can see that the total cost for 10 days is 400 dollars.

First, we know that the cost of renting the cars for 3 days is $120, then we can get the unit rate (cost for a single day) if we take the quotient between the total cost and the number of days, we will get:

$120/3 = $40

Then the cost of 10 days of rent is 10 times the number we found above, then the cost for renting the car 10 days is:

Cost = $40*10

Cost = $400

The cost of renting the car for 10 days is 400 dollars.

Sarah's percentage error is 35%.

The predicted value is 80 words per minute, and the actual value is 52 words per minute.

To find the percentage error, we need to find the difference between the predicted and actual values, divide it by the predicted value, and then multiply by 100 to get the percentage.

Sarah's percentage error can be calculated as follows:

percentage error = |(predicted value - actual value) / actual value| x 100%

Substituting the given values, we get:

percentage error = |(80 - 52) / 80| x 100%

percentage error = |28 / 80| x 100%

percentage error = 0.35 x 100%

percentage error = 35%

The next step to find the y intercepts is the substitute the value of m2 and coordinate of point P in the equation of the line intercepts from equation y= mx + b and then solve for b in each equation.

Bernie wants to write equations in the form of y=mx+b where m stands for slope. The line passing through the point P and that is perpendicular to the s and parallel to the line r.

we are aware that if two lines are parallel then the slopes are equal.

So, m1=m2

and if two lines are perpendicular then product of slopes equal to -1

m1×m2=-1

In a multiple regression model, the error term (often denoted as ε or e) is assumed to be a random variable with a mean of zero.

This assumption is a key component of the regression model and is often referred to as the assumption of zero conditional mean or the assumption of homoscedasticity. The assumption of a mean of zero for the error term means that, on average, the errors have no systematic bias or tendency to overestimate or underestimate the predicted values. It implies that the model's predictions are unbiased and that any deviations from the true values are due to random chance or other factors not captured by the model. The other options presented in the answer choices (B) -1, (C) 1, and (D) any value are incorrect. The mean of the error term is specifically assumed to be zero, as it represents the average deviation of the observed values from the predicted values in the model.

Answer:

347.2 ft ≈ c

Step-by-step explanation:

*The nearest tenth of a foot is 347.2 ft.

Answer:

a. h = A/w = 2 ³/₄ ft

b. A'/A = 2/3

Step-by-step explanation:

a. What is the total height of the wall? Write an equation to represent the situation. Then solve.

The wall is a rectangle and its area is A = wh where w = width and h = height of wall.

Making h subject of the formula,

h = A/w

Now, Since the area of the retaining wall, A is 23 ³/₈ ft² and its width is the length of the portion of the wall which is brick w is 8 ¹/₂ ft, then

h = A/w

= 23 ³/₈ ft² ÷ 8 ¹/₂ ft

= 187/8 ft² ÷ 17/2 ft

= 187/8 ft² × 2/17 ft

= 187/4 ft² × 1/17 ft

= 187/68 ft

= 2 ³/₄ ft

b. If the area of the brick portion of the wall is 15(7/12), what fraction of the wall is brick? Write an equation to show your work.

Since the area of the brick portion of the wall is A' = 15 ⁷/₁₂ ft²  and the total are of the retaining wall is A =  23 ³/₈ ft²

The fraction of the wall that is brick = A'/A

= 15 ⁷/₁₂ ft² ÷ 23 ³/₈ ft²

= 187/12 ÷ 187/8

= 187/12 × 8/187

= 8/12

= 2/3

Answer with Step-by-step explanation:

a) 2 3/4 ÷ 3 = 11/12 feet

11/12 + 11/12 = 1 5/6

Or, you could write an algebraic equation:

2 3/4 ÷ 3 = x.  (3x = 2 3/4)

x = 11/12

The height of the brick proportion of the wall is 1 5/6

b)

You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.

So, your rounded answer should be 16. Or 16 1/2

c)  

Area = 8 1/2 x 2 3/4.

Use Distributive Property to solve the area.

(8 x 2) + (3/4 x 1/2) = x

8 x 2 = 16

3/4 x 1/2 = 3/8

16 + 3/8 = 16 3/8

x = 16 3/8

I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.

Answer:

The product of a repeating decimal (non-zero) and the square root of a non-perfect square would always be irrational.

Step-by-step explanation:

The sum and product between rational numbers are rational.

Fractions, finite decimals, and infinite repeating decimals are all rational numbers.

The square root of a perfect square is a rational number. However, the square root of a non-perfect square is not rational.

Let \(x\) denote a repeating (non-zero) decimal (\(x \ne 0\)). Let and \(y\) denote the square root of a non-perfect square. Note that \(x\!\) would be a rational number, but \(y\) would not be rational.

Assume the product \(x\, y\) to be rational by contradiction. Since \(x \ne 0\) and \(x\) is a rational number, the multiplicative inverse \((1/x)\) of \(x\!\) would be a rational number.

Left-multiply \(x\, y\) by this multiplicative inverse to obtain: \((1/x) \, (x\, y) = ((1/x)\, x)\, y = y\).

Since \((1/x)\) is a rational number, and \(x\, y\) is assumed to be rational, the product \((1/x) \, (x\, y) = y\) should also be rational. This observation is a contradiction with the assumption that \(y\) is not rational.

To find the component form of the velocity of the airplane, we need to break down the velocity vector into its horizontal (x) and vertical (y) components.

Given that the airplane is flying 25 degrees west of north at 800 km/h, we can determine the horizontal and vertical components using trigonometry.

The vertical component (Vy) represents the velocity in the north direction, and the horizontal component (Vx) represents the velocity in the east direction.

To calculate Vy, we use the sine function:

Vy = V * sin(θ)

Vy = 800 * sin(25°)

To calculate Vx, we use the cosine function:

Vx = V * cos(θ)

Vx = 800 * cos(25°)

Therefore, the component form of the velocity vector is:

Velocity = (Vx, Vy) = (800 * cos(25°), 800 * sin(25°))

Calculating the values:

Vx ≈ 722.6 km/h

Vy ≈ 342.0 km/h

Hence, the component form of the velocity vector is approximately (722.6 km/h, 342.0 km/h).
