The expression √x is sometimes a real number, depending on the value of x. It is a real number when x is non-negative (x ≥ 0), but not a real number when x is negative (x < 0).

The square root (√) of a non-negative real number x is always a real number. When x is non-negative (x ≥ 0), √x exists and is a real number. For example, √4 = 2, √9 = 3, and so on.

However, when x is negative (x < 0), the square root of x is not a real number. The square root of a negative number results in a complex number, specifically an imaginary number. For example, √(-4) is not a real number, but it can be expressed as 2i (where i is the imaginary unit).

Step-by-step explanation:

There is a mistake in the problem.

The bottom base has length 10 not 11.

Using the correct length of 10, the area is:

A = (1/2)h(b1 + b2)

A = (1/2)(6)(10 + 8)

A = 3(18)

A = 58

Using the incorrect length of 11, the area is:

A = (1/2)h(b1 + b2)

A = (1/2)(6)(11 + 8)

A = 3(19)

The equation of the locus of the moving point that maintains a distance of 4 units from the X-axis is y = ±4, representing two parallel horizontal lines.

To find the equation of the locus of a point that always maintains a distance of 4 units from the X-axis, let's analyze the given information.

Let P(x, y) be the moving point and Q(x, 0) be the fixed point on the X-axis. The distance between P and Q is denoted by PQ. According to the problem, PQ is always 4 units.

Using the distance formula, we have:

PQ² = (x - x)² + (y - 0)²

Since the x-coordinate of both P and Q is the same (x - x = 0), the equation simplifies to:

PQ² = y²

Substituting the value of PQ as 4 units:

4² = y²

16 = y²

Taking the square root of both sides:

\(\sqrt{16 } = \sqrt{y^2}\)

±4 = y

Therefore, the y-coordinate of the moving point P can be either positive or negative 4, giving us two possible solutions for the y-coordinate.

Hence, the locus of the moving point P that maintains a distance of 4 units from the X-axis is given by the equation:

y = ±4

This equation represents two horizontal lines parallel to the X-axis, with y-coordinates at +4 and -4. Any point (x, y) on these lines will always be at a constant distance of 4 units from the X-axis.

The coefficient of variation (CV) is a measure of relative variability and is calculated by dividing the standard deviation by the mean, and then multiplying by 100 to express it as a percentage.

In this case, the mean weight is 340 grams, and the standard deviation is 5.2 grams.

CV = (Standard Deviation / Mean) * 100

CV = (5.2 / 340) * 100

CV ≈ 1.53%

Therefore, the correct answer is option B: 1.53%.

The formula for the nth term of the sequence is a_n = sin((n-1) * π/2).

The sequence given is {1, 1, 1, 1, 1}. We can observe that the sequence is constant, and hence we can represent it using a constant term.

That is a_n = 1. 2. The sequence given is { -8, 16, -32, 64, ... }.

On observing the sequence, we can see that the terms are generated by multiplying the previous term by -2.

Hence, the nth term can be written as a_n = (-2)^(n-1) * 8, which simplifies to a_n = -8 * 2^(n-1).3.

The given sequence is {1, 0, -1, 0, 1, 0, -1, 0, ...}.

This sequence is periodic and alternates between 1 and -1.

We can represent the sequence using the sine function as follows: a_n = sin((n-1) * π/2).

On substituting the values of n, we can see that this generates the given sequence.

Hence, the formula for the nth term of the sequence is a_n = sin((n-1) * π/2).

The explicit formula for the sequence is aₙ=(-4).(-4)ⁿ⁻¹ and the 8th term is 65536

The given sequence is -4, 16, -64, 256,...

If we observe the sequence it is a geometric sequence

aₙ=a.rⁿ⁻¹

a is the first term and r is the common ratio

From the sequence the first term is -4 and common ratio is -4

aₙ=(-4).(-4)ⁿ⁻¹

Plug in the value n as 8

a₈=(-4).(-4)⁷

The value of minus four power seven is minus sixteen thousand three hundred eighty four

a₈=(-4)(-16384)

When four is multiplied with sixteen thousand three hundred eighty four we get sixty five thousand five hundred thirty six

Answer:

walking speed is 2 m/s

Step-by-step explanation:

given data

distance between Melissa and friend = 3 mile

total time of the trip = 2 hour

solution

we consider here

walking speed = s₁

bike speed = s₂  

so s₂ = s₁ + 4    .................1

and

time is express as

time = distance ÷ speed      .................2

so time for Melissa to friend reach = 3 ÷ s₁    

and time for return from her friend =  3 ÷ s₂  

so put this value in equation 2 we get

time = 3 ÷ s₁  + 3 ÷ s₂  

2 = \(\frac{3}{s_1} + \frac{3}{s_1 + 4}\)    

solve it and we will get

s₁² + s₁ - 6 = 0

s₁ = 2 m/s

so walking speed is 2 m/s

The probability of getting 3 is P(A) = 1/216. The probability that sum being 3 is 1 / 216.

When three dice are thrown simultaneously, the probability that the sum is 3 is 1/216. A dice can show a minimum of one and a maximum of six dots, for a total of six sides, giving it a total of 6 * 6 * 6 = 216 possible outcomes.

:When three dice are thrown simultaneously, the probability that the sum is 3 is 1/216. The probability can be calculated as follows:

Let A be the event that the sum is 3. The number of ways to get 3 is 1, i.e., (1, 1, 1). The total number of possible outcomes is 6³,

since each die can have 6 possible outcomes.

Therefore, the probability of getting 3 is P(A) = 1/216.

In conclusion, the probability that sum being 3 is 1 / 216.

Given,

The radius of the circular track in which the jogger runs = 70 feet

The coordinates of the jogger = (42, 56)

The rate of change in x coordinate = 18 feet/sec

Let (x,y) be the coordinates
