The angle of depression is 32°.

The angle of depression is the angle formed when the item being seen is below the observer's level between the horizontal line and the line of sight of the observer.

The angle of depression is the angle formed by the horizontal axis and the downward axis of a line of sight. As an example, if you were perched on top of a hill or other structure and looked down at an object, you might determine the angle of depression. To measure these angles, a theodolite or a clinometer can be used. The maximum depression angle is 90 degrees. It can't be possible because any rational spectator would turn around the instant the object passed beneath him.

Due to the fact that AB is perpendicular to B and AD is the horizontal line of sight, we can conclude that AD AB (given).

∴ ∠DAB = 90°.

We can express this as DAB = DAC + BAC.

alternatively, 90° = ∠DAC + 58°

alternatively, ∠DAC = 90° - 58° = 32°.

The angle of depression is 32°.

The probability of getting 15 or more heads is :

P (Z > -0.18) = 1 - 0.4289 =  0.5714

Now, According to the question:

Normal Approximation to Binomial:

The normal distribution is used to approximate for the binomial distribution. The condition when binomial distribution is approximated to normal is that n should be large and probability should be close to 0.5

"Information available from the question"

n = 30

Probability, p(heads) = 1/2

Since sample size is large, we check for normal approximation.

np = 30(1/2) = 15

and, n(1 - p) = 30(1 - (1/2)) = 15 both are greater than 5, we use normal approximation.

Mean, μ = np = 30(1/2) = 15

Standard deviation, σ = [tex]\sqrt{np(1-p)}[/tex]

Standard deviation, σ = [tex]\sqrt{30(1/2)(1-1/2)}[/tex]

Standard deviation, σ =2.739

We have to find P (X ≥ 15). Using continuity correction, we deduct 0.5

P(X ≥ 15) = P(X > 14.5)

The respective Z-score with X = 14.5 is

Z = (x - μ)/ σ

Z = (14.5 - 15)/2.739

Z = -0.18

Now, we use z-tables to find probability greater than -0.18

P (Z > -0.18) = 1 - 0.4289 =  0.5714

The largest box that can be formed has a volume of 20 cubic feet.

Let's call the side length of the square cutout x. The original piece of cardboard measures 3 feet by 4 feet, so the dimensions of the piece of cardboard after the cutouts are made are (3 - 2x) by (4 - 2x).

When this piece is folded into a box, the length and width of the box will be (3 - 2x) and (4 - 2x) respectively. The height of the box will be x, as that is the height of the cutout squares.

The volume of the box can be found by multiplying the length, width, and height: V = (3 - 2x)(4 - 2x)x

We want to find the maximum volume, so we need to differentiate the expression for the volume and set it equal to zero, and then solve for x.

dV/dx = 2x(4 - 2x) - (3 - 2x)(2x) = 0

2x(4 - 2x) = (3 - 2x)(2x)

2x(4 - 2x) = 2x^2 - 6x^2

-4x^2 + 4x = 0

x(4 - x) = 0

x = 0 or x = 4

Since the side length of the cutout square cannot be negative, we reject x = 0 and keep x = 4. So, the maximum volume will occur when the side length of the cutout squares is 4 feet.

Substituting x = 4 into the expression for the volume, we find:

V = (3 - 2x)(4 - 2x)x = (3 - 2x)(4 - 2x) = (3 - 2x)(4 - 2x) = (3 - 8)(4 - 8) = -5 * -4 = 20 cubic feet

So, the largest box that can be formed has a volume of 20 cubic feet.

Therefore, The largest box that can be formed has a volume of 20 cubic feet.

It follows that continuity at infinity is provided by having the same limit while approaching it from either side, i.e., the limit towards + and, which makes sense based on your understanding.

When a function can be extended to P1, it is said to be "continuous at infinity" (R).

Calculus's idea of the limit describes how a function behaves as its input gets closer to a particular value. As long as the limit is present, the value that f(x) approaches as x moves closer to c is represented by the notation lim(x -> c) f(x), which stands for the limit of a function at the point x = c.

You must demonstrate that all three of the following conditions are true in order to prove that a function f is continuous on an interval:

Every point in the interval has f specified, and the interval has f's bound.

For each and every > 0, there is a corresponding > 0 such that |x - c| implies |f(x) - f(c)| for all x and all c in the interval.

F is considered to be continuous on the interval if these requirements are met.

Step-by-step explanation:

x^2 - 19x    ± 39       take 1/2 of the 'x' coefficient square it and add and subtract it

x^2 - 19x +  90.25    - 90.25   ±39

(x-9.5)^2   - 90.25 ±39     so I guess the answer is  90.25

The fully factored form of the equation is 2x(x + 3) (2x - 1) that is option B.

Synthetic division and the rational root theorem can be used to demonstrate this. According to the rational root theorem, p must divide the constant term and q must divide the leading coefficient if p/q is a rational root of the polynomial f(x). The constant term in this example is -6, the leading coefficient is 4, and the potential rational roots are 1, 2, 3, and 6.

When we divide 4x3 + 10x2 - 6x by 2x - 1 using synthetic division, we arrive at the following result:

4x^3 + 10x^2 - 6x = (2x - 1) (2x^2 + 8x + 6)

We can then factor the remaining quadratic, 2x^2 + 8x + 6, as (x + 3)(2x + 2).

Thus, the completely factored form of 4x^3 + 10x^2 - 6x is:

4x^3 + 10x^2 - 6x = 2x(x + 3)(2x - 1)

The solutions of x = 0 or x = y  and y = 0 or y = 1 can then be found. Therefore, the solutions of the equation are (0,0), (0,1), (1,0), and (1,1).

x2 - xy + y2 - x = 0

x(x - y) + y(y - 1) = 0

x(x - y) = 0  and  y(y - 1) = 0

x = 0 or x = y  and y = 0 or y = 1

Therefore, the solutions are (0,0), (0,1), (1,0), and (1,1).

The equation z2 z 1 = 0, when written as (x,y)(x,y) (x,y) (1,0) = (0,0), can be manipulated to x2 - xy + y2 - x = 0. By factoring out the x and y terms, the equation can be rearranged to x(x - y) + y(y - 1) = 0. This then can be further simplified to x(x - y) = 0  and  y(y - 1) = 0.

The calculation would have three significant figures, since both original numbers have three significant figure.

The number of significant figures in a calculation is determined by the number of significant figures in the original numbers used in the calculation. For example, if we have the calculation 3.14 + 2.7 = 5.84, the answer will have three significant figures because the original numbers, 3.14 and 2.7, each have three significant figures.

In general, significant figures are determined by counting all non-zero digits, plus any zeros that come between non-zero digits, such as in the numbers 10.0 and 0.07. If a number is a decimal, the zeros after the decimal point are also significant, such as in the number 0.07. Zeros that come before the first non-zero digit are not significant, such as in the number 0.0007.

Answer: The answer is 3.

Step-by-step explanation:

Ohm's Law states that the current passing through a conductor is proportional to the voltage across the conductor, and inversely proportional to the resistance of the conductor.

Mathematically, this can be expressed as:

V = IR,

where V is the voltage, I is the current, and R is the resistance of the conductor. The resistance of a conductor is given by:

R = ρℓ/a,

where ρ is the resistivity of the material, ℓ is the length of the conductor, and a is the cross-sectional area.

From Ohm's Law, we can also derive an expression for the electric field inside the conductor:

E = V/ℓ = IR/ℓ = ρI/a

In the case of conductors 1 and 2, the voltage across both conductors is the same (v2 = v1), so the electric field in conductor 2 can be expressed as:

E2 = V2/ℓ2 = v1/(2ℓ1) = ρI2/a2 = (ρ/2a1)I2

Similarly, the electric field in conductor 1 can be expressed as:

E1 = V1/ℓ1 = v1/ℓ1 = ρI1/a1 = (ρ/a1)I1

Finally, the ratio of the electric fields in conductors 1 and 2 can be calculated as:

E2/E1 = (ρ/2a1)I2 / (ρ/a1)I1 = a1/2a1 = 1/2

So, the ratio of the electric fields, E2/E1, is equal to 1/2. This means that the electric field in conductor 2 is half the electric field in conductor 1, despite the fact that the voltage across both conductors is the same. This happens because the cross-sectional area of conductor 2 is twice that of conductor 1, which compensates for the fact that the length of conductor 2 is also twice that of conductor 1.

The probability that a randomly selected call time will be less than 30 seconds is approximately 0.7445.

The problem involves exponential distribution which is a standard continuous distribution. The probability density function of this distribution is given by -

f(x) = θe^(-θx) ; where θ is a parameter and characteristic of the distribution, x is the random variable.

Also, the mean for an exponential distribution is given by u = 1/θ .

In the question it is 22 seconds.

So, the value of θ is 1/22.

Now, we have to find P(X<30) where X is the random variable denoting the calling time in seconds.

P(X<30) is nothing but F(x) at x = 30 seconds, i.e. cumulative distribution function. For an exponential distribution , F(X) is given by -

P(X<x)= F(X) = 1- e^(-θ x) , where x>0.

Putting θ = 1/22 and x= 30 in F(X) , we get -

F(X) = 1-e[(-1/22)30] = 1- 0.2555 = 0.7445 which is P(X<x) = P(X<30) = 0.7445.
