What fraction is equal to 15/18

Arcs get their angle measure from the central angle they're in, in this case the central angle of 86°, central to arcED, has a counterpart of a twin vertical angle across the center, since both vertical angles are identical twins that means the central angle for arcAB is 86° also, and that's the arcAB's measure too.

The graph of the given inequalities is Attached below.

From the given inequalities:

As the first inequality is not strictly true, the graph of it is a straight solid line that passes through the points (0, 2) and (2/3, 0), with the shaded area being further from the origin ( as it fails the zero point test )

As the second inequality is not stringent, the graph of the inequality is a straight solid line that passes through the points (0,-4) and (8,0), with the shaded area pointing in the direction of the origin (since the inequality passes the zero point test)

Complete question:

Which graph represents the system of inequalities?

y + 3x ≥ 2

y + 4 ≥ 1/2x

Answer:

x=28

x=-28

Step-by-step explanation:

The inverse function of f(x) = (x - 3)²- 4 is f-1(x) = 3 + √(x + 4)

From the question, we have the following parameters that can be used in our computation:

f(x) = (x - 3)²- 4

Rewrite as

y = (x - 3)²- 4

Swap x and y

So, we have

x = (y - 3)²- 4

This gives

(y - 3)² = x +  4

Take teh square roots of both sides

y - 3 = √(x + 4)

So, we have

y = 3 + √(x + 4)

So, the inverse function is f-1(x) = 3 + √(x + 4)

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.

We know that,

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.

The explicit formula for any arithmetic series is given by the formula,

a_n = a_1 + (n-1)d

where d is the difference and a₁ is the first term of the sequence.

The major distinction between recursive and explicit formulas is that a recursive formula returns the value of a particular term depending on the preceding term, whereas an explicit formula returns the value of a given term based on its location.

When the value of the first term and the common difference is known then an explicit formula is used, while the recursive formula will be used when the value of the previous value is known and the value of the common difference is known.

Answer:

  (a) ∠7 = 47°. Angles 5 and 7 are vertical angles, hence congruent.

  (b) 47 +(2x -5) = 180

  (c) 69

Step-by-step explanation:

Given angles identified as ∠5, ∠6, ∠7 where two lines cross, and the measure of ∠5 as 47°, you want the measure of ∠7, and an equation and solution when ∠6 is (2x-5).

Angles that share a vertex and are formed from opposite rays are "vertical angles." They are congruent.

Angles 5 and 7 are vertical angles, so the measure of angle 7 is the same as the measure of angle 5.

  ∠7 = 47°

Angles that form a linear pair are supplementary. This means the sum of angles 5 and 6 is 180°.

  ∠5 +∠6 = 180°

It is fair to assume that the spinner will land on an odd number 160 times.

The likelihood of landing on any one of the eight congruent portions of the spinner is 1/8. This information allows us to reasonably forecast the frequency with which the spinner will fall on an odd number.

The likelihood of landing on an odd number is 4/8 or 1/2 since the spinner has four odd numbers (1, 3, 5, and 7) and four even numbers (2, 4, 6, and 8). Thus, we may anticipate that the spinner will land on an odd number on average 50% of the time.

If the spinner is spun 320 times, we would expect it to land on an odd number about half of those times, or approximately:

(1/2) x 320 = 160

Therefore, the probability that the spinner will fall on an odd number 160 times is fair.

A reasonable prediction for the number of times the spinner will land on an odd number is 160.

We have,

Since the spinner has eight congruent sections, each odd number (1, 3, 5, and 7) appears once on the spinner, and there are a total of four odd numbers.

Since the spinner is spun 320 times, we can expect each section of the spinner to be landed on equally, on average.

Therefore, the expected number of times the spinner will land on any one section is 320/8 = 40.

Since each odd number appears once on the spinner, we can expect the spinner to land on an odd number 4 times in every 8 spins, or once in every 2 spins.

Therefore, the expected number of times the spinner will land on an odd number in 320 spins is approximately 320/2 = 160.

Thus,

A reasonable prediction for the number of times the spinner will land on an odd number is 160.

The standard form of the equation of the hyperbola is

[(y + 6)²/4] - [(x - 3)²/16] = 1.08

We have,

To find the standard form of the equation of a hyperbola, we need to know the locations of the vertices and the foci.

In this case, we are given the coordinates of the vertices, but we need to find the foci. However, we are also given that the hyperbola passes through the point (7, −12), which will allow us to find the foci.

First, let's find the center of the hyperbola.

Since the vertices have the same x-coordinate of 3, the center must be the point (3, −6), which is the midpoint of the two vertices.

Next, we can find the distance between the center and one of the vertices. Using the distance formula, we get:

d = √[(3 - 3)² + (-8 - (-6))²] = 2

Since the vertices are vertically aligned, we know that the distance from the center to each vertex is the same.

Therefore, the distance from the center to each vertex is also 2.

We can now use the Pythagorean theorem to find the distance from the center to each focus, which we will call c.

We know that c² = a² + b², where a is half the distance between the vertices (in this case, a = 2), and b is half the distance between the foci.

We want to solve for b.

Since the hyperbola passes through the point (7, −12), we know that the distance from this point to each focus is constant and equal to the distance from this point to the center of the hyperbola.

Using the distance formula, we can set up the following equation:

√[(7 - 3)² + (-12 - (-6))²] = sqrt[(7 - 3)^²+ (-12 - (-8))²] + b

Simplifying this equation, we get:

2 √(37) = 2 √(20) + b

b = √(37) - √(20)

Now that we have the values of a and b, we can write the standard form of the equation of the hyperbola:

[(y + 6)²/4] - [(x - 3)²/16] = 1 + [(√(37) - √(20))²/16]

Simplifying, we get:

[(y + 6)²/4] - [(x - 3)²/16] = 1.08

Therefore,

The standard form of the equation of the hyperbola is

[(y + 6)²/4] - [(x - 3)²/16] = 1.08
