Answer:

Step-by-step explanation:

775625 is the correct answer

Answer:

First, we can multiply both sides of the equation by the absolute value of x plus 8, to get rid of the fraction:

52 = 4(|x| + 8)

Now we can solve for the absolute value of x:

| x | + 8 = 13

| x | = 5

This means that x could be either positive 5 or negative 5. Therefore, the possible values of x are {-5, 5}.

So the answer is option D: {-5, 5}.

The 30th partial sum of the sequence 5x-12 = 1965

To derive the 30th partial sum of the sequence 5x -12, we need to add up to the first 30 terms of the sequence.

Th e nth term of the sequence will be:

5 -12

the first 30th terms are:

5(1) -12 = -7

5(2) -12 = -2

5(3) -12 = -3

5(4)  -12 = -8

and so on

So to get the 30th partial sum, we write:
-7 + (-2) = 3+ 8 ...... + (5(30)-12

If simplified, this expression will given us:

S = (n/2) (a+l)

In this case,

s is the sum of the n terms
A is the first term and
L is the last term.

In this ase, a = -7 (the first term) and L= 5(30) -12 = 138 (the 30th term) So  for the partial sum we say:

S30 = (30/2) (-7 + 138) = 30(131)/2
S30 = 1965

Thus, the partial sum of the sequence 5x-12) is 1965

Answer: 33.375 feet

Step-by-step explanation:

To find the maximum height, we need to find the vertex of the parabolic function h = 16t² + 12t + 30.

The vertex of a parabola with equation y = ax^2 + bx + c is located at x = -b/2a and y = c - b^2/4a.

In this case, a = 16, b = 12, and c = 30.

So,

t = -b/2a = -12/(2*16) = -3/8

h = 16(-3/8)² + 12(-3/8) + 30 = 33.375

Therefore, the maximum height reached is 33.375 feet.

Pi/(180 degrees) equals 1 degree in radians.

Radians are a unit of measurement for angles, just like degrees. The radian is defined as the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle.

To visualize this, imagine taking a circle with a radius of r and drawing an arc on the circle that is the same length as the radius. The angle subtended by this arc at the center of the circle is one radian. Since the circumference of a circle is 2pir, there are always 2*pi b in a full circle.

(180 degrees)/pi is equivalent to the value of 180 degrees in radians. To convert from degrees to radians, we multiply the degree value by (pi/180). So:

(180 degrees)/pi = (180 degrees) * (pi/180) = pi radians

Therefore, (180 degrees)/pi equals pi in radians.

On the other hand, pi/(180 degrees) is equivalent to the value of 1 degree in radians. To convert from radians to degrees, we multiply the radian value by (180/pi). So:

pi/(180 degrees) = pi * (180/pi) = 180 degrees

Therefore, pi/(180 degrees) equals 1 degree in radians.

The statement "An estimator is consistent if as the sample size decreases, the value of the estimator approaches the value of the parameter estimated" is False.

Consistency is an important property of estimators in statistics. An estimator is consistent if its value approaches the true value of the parameter being estimated as the sample size increases.

In other words, if we repeatedly take samples from the population and compute the estimator, the values we obtain will be close to the true parameter value.

This is an essential characteristic of a good estimator, as it ensures that as more data is collected, the estimation error decreases.

However, as the sample size decreases, the value of the estimator is more likely to deviate from the true value of the parameter. The reason for this is that a small sample size may not be representative of the population, and as a result, the estimation error may increase.

As a consequence, the statement is false. In conclusion, consistency is a property that an estimator possesses when its value converges to the true value of the parameter as the sample size grows.

As the sample size decreases, the estimator may become less reliable, leading to an increase in the estimation error.

A circle with center Q and equilateral triangle NOP, where points N and O lie on the circle

What is a circle?

A circle is a two-dimensional shape with a perfectly round boundary that has no corners or edges. It is defined as the set of all points in a plane that are equidistant from a fixed point called the center. The distance from the center to any point on the boundary of the circle is called the radius.

The circumference of a circle is the distance around the boundary of the circle, and it is calculated as 2π times the radius. Circles are found in many natural and man-made objects, such as wheels, planets, and coins, and they have a wide range of applications in mathematics, science, and engineering.

To construct a circle with center Q and equilateral triangle NOP where points N and O lie on the circle, follow these steps:

Draw line segment PQ as the base of the equilateral triangle NOP.

Draw a perpendicular bisector of PQ, which intersects PQ at its midpoint, say M. This bisector will be the axis of symmetry of the equilateral triangle NOP.

With M as the center and MP (or MQ) as the radius, draw a circle that intersects PQ at two points, say X and Y.

Using Q as the center and QX (or QY) as the radius, draw two arcs that intersect the circle drawn in step 3 at two points, say N and O.

Draw the lines NQ and OQ to complete the equilateral triangle NOP.

Answer:

We can use the double angle formulas to find sin(2θ) and cos(2θ):

sin(2θ) = 2sin(θ)cos(θ)

cos(2θ) = cos^2(θ) - sin^2(θ)

Since sin(θ) = -4/5 and θ is in the third quadrant (π < θ < 3π/2), we can use the Pythagorean identity to find cos(θ):

sin^2(θ) + cos^2(θ) = 1

cos^2(θ) = 1 - sin^2(θ)

cos(θ) = -√(1 - sin^2(θ))

cos(θ) = -√(1 - (-4/5)^2) = -√(1 - 16/25) = -√(9/25) = -3/5

Now we can substitute these values into the double angle formulas:

sin(2θ) = 2sin(θ)cos(θ) = 2(-4/5)(-3/5) = 24/25

cos(2θ) = cos^2(θ) - sin^2(θ) = (-3/5)^2 - (-4/5)^2 = 9/25 - 16/25 = -7/25

Therefore, the exact values of sin(2θ) and cos(2θ) are sin(2θ) = 24/25 and cos(2θ) = -7/25, respectively.

Finally, we can find the value of sin^2(2θ)cos^2(2θ):

sin^2(2θ)cos^2(2θ) = (sin(2θ))^2(cos(2θ))^2

sin^2(2θ)cos^2(2θ) = (24/25)^2(-7/25)^2

sin^2(2θ)cos^2(2θ) = 24^2/25^2 * 7^2/25^2

sin^2(2θ)cos^2(2θ) = (24*7)^2/25^4

Therefore, the exact value of sin^2(2θ)cos^2(2θ) is (24*7)^2/25^4.

A trigonometric formula known as the rule of sines connects any triangle's sides and angles. It claims that for all three sides of a triangle, the ratio of the length of one side to the sine of the angle opposite that side is the same. In other words, if a triangle has angles A, B, and C opposing its sides and sides a, b, and c, then:

If a/sin(A) = b/sin(B) = c/sin(C), then

If some of the other sides and angles of a triangle are known, this formula can be used to solve for those unknown sides or angles. However, it is restricted to triangles and calls for the measurement of at least one angle and one side's length.

The situation can be depicted as a right triangle, with building 200 feet, the angle of depression is 30 degrees.

so to find the number of acres divide 792 by 18,

which would give you 44.

According to the given condition, the answer is (b) 44. There are 44 acres in Orangeland.

Expressions can be simple or complex, and can be used in many different contexts depending on the specific programming language or mathematical system being used.

The problem asks us to find the number of acres in Orangeland given the population density of orange trees and the total number of trees. We can use the formula for population density, which relates the number of individuals (in this case, orange trees) to the area they occupy.

The formula for population density is:

Population density = number of individuals/area

We can rearrange this formula to solve for the area:

Area = number of individuals/population density

In this problem, we are given the population density of Orangeland, which is 18 orange trees per acre. We are also given the total number of orange trees, which is 792. To find the area of Orangeland, we can substitute these values into the formula:

Area = 792 / 18

Simplifying this expression, we get:

Area = 44

Therefore, According to the given condition, the answer is (b) 44. There are 44 acres in Orangeland.
