The value of cos(45°) is √2/2. The correct answer choice is D. √2.

In the given diagram, the angle labeled as 45° is part of a right triangle. To find the value of cos(45°), we need to determine the ratio of the adjacent side to the hypotenuse.

Since the angle is 45°, we can assume that the triangle is an isosceles right triangle, meaning the two legs are congruent. Let's assume the length of one leg is x. Then, by the Pythagorean theorem, the length of the hypotenuse would be x√2.

Now, using the definition of cosine, which is adjacent/hypotenuse, we can substitute the values:

cos(45°) = x/(x√2) = 1/√2

Simplifying further, we rationalize the denominator:

cos(45°) = 1/√2 * √2/√2 = √2/2

Therefore, the value of cos(45°) is √2/2.

The correct answer choice is D. √2.

7 is not included and hence it is depicted on the number line using an open dot. Hence, solution to the inequality is option B.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

The given inequality is:

x + 8 > 15

Subtracting 8 on both sides of the equation:

x + 8 - 8 > 15 - 8

x > 7

Answer:

This is a binomial distribution problem with n = 6, p = 0.713, and q = 1 - p = 1 - 0.713 = 0.287. We want to find the probability that at least two of the six freshman reply "yes."

Using the binomial probability formula, we can calculate the probability of each possible outcome:

P(X = 0) = (6 choose 0) * 0.713^0 * 0.287^6 = 0.0022

P(X = 1) = (6 choose 1) * 0.713^1 * 0.287^5 = 0.0262

P(X = 2) = (6 choose 2) * 0.713^2 * 0.287^4 = 0.1283

P(X = 3) = (6 choose 3) * 0.713^3 * 0.287^3 = 0.2822

P(X = 4) = (6 choose 4) * 0.713^4 * 0.287^2 = 0.3076

P(X = 5) = (6 choose 5) * 0.713^5 * 0.287^1 = 0.1786

P(X = 6) = (6 choose 6) * 0.713^6 * 0.287^0 = 0.0458

To find the probability that at least two of the six freshman reply "yes," we need to add the probabilities of the outcomes where X is greater than or equal to 2:

P(X >= 2) = P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)

= 0.1283 + 0.2822 + 0.3076 + 0.1786 + 0.0458

= 0.9425

Therefore, the probability that at least two of the six freshman reply "yes" is approximately 0.9425, or 94.25%.

Using the average rate of change concept, we have that:

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

\(r = \frac{f(b) - f(a)}{b - a}\)

For item 1, when the time in minutes changes by 1, the height changes by 9.5 units, hence the rate is given by:

r = 9.5/1 = 9.5 feet per minute.

For item 2, we want a table with a rate of -3, hence, when the first column changes by 1, the second column should always change by -3, hence the table is:

The distance between point T (-5, 1) and point I (-1, 1) is 4 units.

To find the distance between two points, we can use the distance formula, which is derived from the Pythagorean theorem. The formula is:

Distance = √((x2 - x1)² + (y2 - y1)²)

Let's apply this formula to find the distance between point T (-5, 1) and point I (-1, 1):

x1 = -5, y1 = 1 (coordinates of point T)

x2 = -1, y2 = 1 (coordinates of point I)

Plugging these values into the formula, we have:

Distance = √((-1 - (-5))² + (1 - 1)²)

        = √(4² + 0²)

        = √(16 + 0)

        = √16

        = 4

Therefore, the distance between point T (-5, 1) and point I (-1, 1) is 4 units.

Answer:

In mathematics, the extrema of a function refer to the maximum and minimum values that the function can take on. These values can be local extrema, which occur within a certain range of the function, or global extrema, which are the maximum and minimum values over the entire domain of the function.

To find the extrema of a function, one can use a variety of techniques, such as taking the derivative of the function and setting it equal to zero to find the points of stationary values, or using the second derivative test to determine whether a stationary point is a local maximum or minimum.

Interpreting the extrema of a function can provide valuable information about the behavior of the function. For example, the global maximum of a function might represent the highest possible value that the function can attain, while the global minimum might represent the lowest possible value. Local extrema can also be important, as they can indicate changes in the slope or concavity of the function, which can have important implications for applications such as optimization or modeling real-world phenomena.

The project percentage decrease in the combined consumer goods import for both countries between Y and Y+4 is option (b) 33%.

To calculate the percentage decrease in the combined consumer goods import between years Y and Y+4, we first need to calculate the difference between the imports in those years.

The difference in imports is

300 - 450 = -150

Since the difference is negative, this means that there was a decrease in imports between those years.

To calculate the percentage decrease, we need to divide the difference by the initial value (imports at Y) and multiply by 100

Percentage decrease = (difference / initial value) x 100

Percentage decrease = (-150 / 450) x 100

Percentage decrease = -33.33%

Therefore, the correct option is (b) 33%.

Step-by-step explanation:

K(3, - 3)

L(2, 1)

\(m_{KL}\) = \(\frac{-3-1}{3-2}\) = - 4

Slope of perpendicular line is \(\frac{1}{4}\)

y - 1 = - 4(x - 2) ⇔ y = - 4x + 9

Equation of the perpendicular to KL from point M(4, - 3) is

y - (- 3) = \(\frac{1}{4}\) (x - 4) ⇔ y = \(\frac{1}{4}\) x - 4 ....... (1)

L(2, 1)

M(4, - 3)

\(m_{LM}\) = \(\frac{-3-1}{4-2}\) = - 2

Slope of perpendicular line is \(\frac{1}{2}\)  

y - 1 = - 2(x - 2) ⇔ y = - 2x + 5

Equation of the perpendicular to LM from point K(3, - 3) is

y + 3 = \(\frac{1}{2}\) (x - 3) ⇔ y = \(\frac{1}{2}\) x - 4.5 ....... (2)

The coordinates of the intersect of lines (1) and (2)

\(\frac{1}{2}\) x - 4.5 = \(\frac{1}{4}\) x - 4 ⇒ \(\frac{1}{4}\) x = 0.5 ⇒ x = 2

y = \(\frac{1}{2}\) (2) - 4.5 ⇒ y = - 3.5

a) A negative number on the x-axis (-a, b) would move in the left direction by one unit.

To find out why, check point (0, b) on the y-axis and point (-a, b) on the x-axis.

The distance between these two points is a unit, meaning that the point (-a, b) is one unit to the left of the point (0, b).

b) A positive number on the x-axis (+a, b) would move in the right direction by a unit.

Again, let's look at the point (0, b) on the y-axis and the point (+a, b) on the x-axis.

The distance between the two points is also one unit, which means the point (+a, b) is one unit to the right of the point (0, b).

c) A negative number on the y-axis (a, -b) would move in the downward direction by b units.

Assume that point (a, 0) is on the x-axis and point (a, -b) is on the y-axis. The distance between them is b units, which means that the point (a, -b) is b units below the point (a, 0).

d) A positive number on the y-axis (a, +b) would move in the upward direction by b units.

Also, check the point (a, 0) on the x-axis and point (a, +b) on the y-axis. The distance between these two points is b units, which means that the point (a, +b) is b units above the point (a, 0).

x and y have the values 7 and 7√2, respectively.

The sides of a right triangle with 45-degree acute angles have a unique ratio of 1:1:2.

We can use this information to determine the values of x and y because the base is specified as being 7.

Let's give the perpendicular side the value of x, and the hypotenuse the value of y.

The perpendicular side (x) and the base (7) have the same length because the acute angles are both 45 degrees.

Consequently, x = 7.

We can determine that x:y:2x using the ratio of 1:1:2.

When we enter the value of x, we may calculate y:

7:y:√2(7)

Simplifying even more

7:y:7√2

Given that the hypotenuse (y) equals 72, we can write:
