Answer:

∠ EDF = 23°

Step-by-step explanation:

angles on the circumference of a circle ( inscribed angles) subtended by the same arc are congruent.

∠ FGE and ∠ EDF are inscribed angles subtended by arc EF

then ∠ EDF = ∠ FGE = 23°

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant. The size of ∠EDF is 23°.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

As it is known that the angles made from the same chord in a circle are of equal measurement.

Since EF is the chord of the circle and the measure of ∠EGF is 23°, the measure of ∠EDF will be 23° as well.

Hence,  the size of ∠EDF is 23°.

The remaining distance Jada has to bike is 19/10 km.

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage.

Jada biked for 3.5 kilometers before stopping to adjust the helmet.

d₁ = 3/5 kilometer

Jada bikes another 1/2 kilometer and stopped to drink water.

d₂ = 1/2 kilometer

The total distance Jada has to bike is 3 kilometers.

The distance traveled by Jada is:

= d₁ + d₂

= 3/5 km + 1/2 km

Using LCM,

= ( 6 + 5 ) / 10

= 11/10 km

The distance remaining to cover is :

The panicked reaction to the Ebola virus outbreak in 2014 can be attributed to several barriers to reasoning rationally.

These barriers include:

1. Availability Bias: People tend to overestimate the probability of an event occurring based on how easily they can recall similar instances. In the case of the Ebola virus, the extensive media coverage and graphic images of the outbreak may have made it seem more widespread and dangerous than it actually was.

2. Negativity Bias: People are more influenced by negative information and tend to focus on potential risks and threats. The fear of contracting a deadly virus like Ebola overshadowed the low probability of actually being infected.

3. Loss Aversion: People tend to have a stronger emotional response to potential losses than to gains. The fear of losing one's health and safety to a deadly virus can lead to exaggerated reactions and panic.

4. Overgeneralization: People often make generalizations based on limited or incomplete information. In the case of the Ebola outbreak, the limited number of cases in the United States led to the assumption that the virus was highly contagious and posed a significant risk to the general population.

It is important to note that these barriers to reasoning can hinder our ability to think rationally and make informed decisions. Understanding these biases can help us approach situations with a more balanced and evidence-based perspective.

If the magnitude of the second derivative, |f''|, is small on a given 6-interval centered at a, then the slopes of the tangent lines change slowly as r increases over the interval.

The second derivative, f'', measures the rate of change of the slope of a function f. If |f''| is small, it implies that the rate of change of the slope is small. In other words, the function is relatively "smooth" or "flat" on the interval.

When the function is smooth, the tangent lines to the curve change slowly as the parameter r increases. This means that for small changes in r, the slopes of the tangent lines will not vary significantly. The graph of the function will exhibit a gradual change, without sudden or rapid fluctuations in the steepness of the curve.

Conversely, if |f''| were large on the 6-interval, it would indicate that the function has more pronounced changes in slope. In such cases, the tangent lines would change quickly as r increases, resulting in a graph with more abrupt variations in steepness.

Therefore, when the magnitude of the second derivative is small on a given 6-interval with center a, the slopes of the tangent lines change slowly as r increases over the interval.

Step-by-step explanation:

Similar Triangles

Two triangles are similar if their corresponding sides are always in the same ratio.

In similar triangles,  corresponding angles are always congruent.

From inspection of the given diagram, the two triangles are similar as their corresponding sides are in the same ratio.  Therefore, their corresponding angles are equal:

⇒ 2x - 19° = x + 63°

⇒ 2x - 19° - x = x + 63° - x

⇒ x - 19° = 63°

⇒ x - 19° + 19°= 63° + 19°

⇒ x = 82°

Let's break this problem down step by step.

First, we can work out the weight of one white ball by subtracting the weight of 6 white and 3 orange balls (20 pounds) from the weight of 2 white and 5 orange balls (8 pounds):

Weight of 1 white ball = 8 - 20 = -12

Next, we can work out the weight of one orange ball by subtracting the weight of 2 white and 5 orange balls (8 pounds) from the weight of 6 white and 3 orange balls (20 pounds):

Weight of 1 orange ball = 20 - 8 = 12

Now that we know how much one white and one orange ball weigh, we can work out the weight of 4 white and 4 orange balls together:

Weight of 4 white and 4 orange balls = (4 x -12) + (4 x 12) = 0

Therefore, the weight of 4 white and 4 orange balls together is 0 pounds.

By solving two given simultaneous equations using algebra, we find that the combined weight of 4 white balls and 4 orange balls is 16 pounds.

The subject matter of this question pertains to simultaneous equations. The equations in question are, 2w + 5o = 8 and 6w + 3o = 20, where w stands for the weight of a white ball and o stands for the weight of an orange ball. We can solve these equations to find the individual weights of these balls. After finding these values, we substitute these into a new equation, 4w + 4o, to find the total weight of 4 white and 4 orange balls together. By solving these equations, we find that the weight of 4 white balls and 4 orange balls together is 16 pounds.

A linear equation is an equation in which each term has at max one degree. The correct option is b.

A linear equation is an equation in which each term has at max one degree. Linear equations in variables x and y can be written in the form

y=mx + c

Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.

Given the relationship is linear, therefore, the value of the slope will be,

m = (3-2)/(2-1) = 1/1 = 1

Now, if we substitute the value of x and y in the relationship, then,

2 = 1(1) + c

2 = 1 + c

c = 2-1

c = 1

1. The area of square C is 625 ft². 2. The perimeter of square C is 46 ft. 3. The area of square B is 1456 ft². 4. The length of square A is 4√15 ft.

A key idea in geometry that connects the lengths of a right triangle's sides is known as the Pythagorean Theorem. It says that the hypotenuse's square length, which is the side that faces the right angle, is equal to the sum of the squares of the lengths of the other two sides in a right triangle. It has the following mathematical expression:

a² + b² = c²

1. The area of square C can be found using the Pythagorean Theorem:

a² + b² = c²

Using the area the side is calculates as follows:

Side length of A = √225 = 15 ft

Side length of B = √400 = 20 ft

Now,

15² + 20² = c²

225 + 400 = c²

625 = c²

c = √625 = 25 ft

So the area of square C is:

Area of C = 25² = 625 ft²

2. The perimeter of square C can be found by adding up the side lengths of all three squares:

Perimeter of A = 36 ft, so each side length of A is 9 ft.

Perimeter of B = 48 ft, so each side length of B is 12 ft.

Perimeter of C = Side length of A + Side length of B + Side length of C

Perimeter of C = 9 + 12 + c

We found earlier that c = 25 ft, so we can substitute that in:

Perimeter of C = 9 + 12 + 25 = 46 ft

3. The area of square B can be found using the fact that the areas of squares A, B, and C are related by the equation:

Area of A + Area of B = Area of C

We know the area of A and the area of C, so we can solve for the area of B:

Area of A = 15² = 225 ft²

Area of C = 1681 ft²

Area of A + Area of B = Area of C

225 + Area of B = 1681

Area of B = 1456 ft²

4. Perimeter of B = 64 ft

Side length of B = 64 / 4 = 16 ft

Now we can use the Pythagorean Theorem to find the side length of C:

a² + b² = c²

a = 15 ft (side length of A)

b = 16 ft (side length of B)

c = √(a² + b²) = √(15² + 16²) = √481 = 22 ft

Finally, we can use the Pythagorean Theorem again to find the side length of A:

a² + b² = c²

b = 16 ft (side length of B)

c = 22 ft (side length of C)

a = √(c² - b²) = √(22² - 16²) = √240 = 4√15 ft

It could be

ax(x - 4)(x - 3)(x + 3)     where a is some constant ( a could be 1 of course)

For a = 1 the polynomial is

x(x - 4)(x - 3)(x + 3)

In expanded form this is

x^4 - 4x^3 - 9x^2 + 36x

The inequality for the expression will be represented by n > 5.

The parameters present shows a geometric sequence. A Geometric sequence is the one in which the ratio between the consecutive terms remains constant. The constant ratio is called common ratio. The nth term of geometric sequence is represented by Tₙ = arⁿ⁻¹ where n is the number of terms, r is common ratio and a is the first term. Here, a = 15 and r = 3. Now, for the people to be more than 3000 the inequality can be written as

arⁿ⁻¹ > 3000

15 (3)ⁿ⁻¹ > 3000

3ⁿ⁻¹ > 200

Taking log on both sides

log 3ⁿ⁻¹ > log 200

(n - 1) > log 200/log 3

n - 1 > 4.82

n > 5.82

- Events A, B, C, and D are exhaustive.
- Events A and B, B and D are not mutually exclusive.
- Events A and C, C and D, A and D are mutually exclusive.

To determine whether the events are exhaustive or mutually exclusive, we need to understand the definitions of these terms:
1. Exhaustive events: Events are considered exhaustive if the union of all the events covers the entire sample space S. In other words, there are no outcomes in the sample space that are not included in any of the events.
2. Mutually exclusive events: Events are considered mutually exclusive if they have no outcomes in common. In other words, the events cannot occur simultaneously.
Now let's analyze the given events:
A = {1, 2, 4}
B = {1, 2, 4, 5, 6}
C = {5, 6}
D = {2, 3, 6}
To determine if the events are exhaustive, we need to check if their union covers the entire sample space S.
The union of A, B, C, and D is {1, 2, 3, 4, 5, 6}, which covers the entire sample space S. Therefore, the events A, B, C, and D are exhaustive.

To determine if the events are mutually exclusive, we need to check if any outcomes are shared between the events.
The outcomes 1, 2, and 4 are shared between events A and B. Therefore, events A and B are not mutually exclusive.
The outcomes 2 and 6 are shared between events B and D. Therefore, events B and D are not mutually exclusive.
No outcomes are shared between events A and C, C and D, or A and D. Therefore, events A and C, C and D, and A and D are mutually exclusive.
