The mode is the number repeated most often, so if we arrange these numbers in order, we can see what numbers repeat the most-

1 1 1 2 3 3 5 7 8 8 9

The number that repeats the most is 1

(1 counted 3 times)

(3 counted twice)

(8 counted twice)

The mode for the set of values is 1. It's calculated by counting how many times a number appears in a data collection.

Mode is the number in the data set repeating maximum number of times. It is obtained by calculating how many times the number are repeating in a data set.

The given data set is;

5 9 1 2 7 3 1 8 8 1 3

Numbers      Count (No of times)

1                        3

3                       2

8                       2  

1 is the most repeating number. It repeats three times.

Answer:

Step-by-step explanation:

Expression: (2⁸ ⋅ 5⁻⁵ ⋅ 19⁰)⁻² ⋅ (5⁻²/2³)⁴ ⋅ 2²⁸

Inner-most powers: 2⁻¹⁶ • 5¹⁰ • 1 • 5⁻⁸/2¹² • 2²⁸

Combine like terms: 2¹² • 5²/2¹²

Cancel out: 5²

Solve: 25

The expression (2^8 ⋅ 5^−5 ⋅ 19^0)^−2 ⋅ 5^-2/(2^3)^4 ⋅ 2^28 simplifies to 2^24 * 5^8.

To find the simplified form of the expression (2^8 ⋅ 5^−5 ⋅ 19^0)^−2 ⋅ 5^-2/(2^3)^4 ⋅ 2^28, you use the properties of exponentiation.

First, any number to the power of 0 is always 1, so 19^0 is 1. Also, any number to a negative power is just the inverse of that number to the positive power. Thus, 5^−5 becomes 1/(5^5). So, the part in parentheses simplifies as follows:

2^8 ⋅ 5^−5 ⋅ 19^0 = 2^8 * 1/(5^5) * 1 = 2^8 / 5^5.

To raise this fraction to the negative 2 power, you swap the numerator and the denominator and raise it to the positive 2 power:

[tex](2^8 / 5^5)^-2 = (5^5 / 2^8)^2 = 5^1^0 / 2^1^6.[/tex]

Next, we tackle the second part of the expression: 5^(-2) / (2^3)^4 = 1/(5^2) / 2^12 = 2^12 / 5^2.

Finally, we multiply this by 2^28.

So, the entire expression simplifies to:

[tex]5^1^0 / 2^1^6 * 2^1^2 / 5^2 * 2^2^8 = 5^1^0 * 2^1^2 * 2^2^8 / (2^1^6 * 5^2) = 5^8 * 2^2^4 = 2^2^4 * 5^8[/tex]

The chemical reaction between hydrogen and chlorine to form hydrochloric acid is balanced as H2 + Cl2 -> 2HCI. This denotes one molecule of hydrogen and one molecule of chlorine reacting to produce two molecules of hydrochloric acid.

The equation presented in the question is H2 + Cl2 -> HCI. This is a chemical reaction in which hydrogen (H2) and Chlorine (Cl2) react to form hydrochloric acid (HCI). However, the equation is not balanced as it stands. Balancing a chemical equation involves ensuring that there are equal numbers of each type of atom on each side of the equation.

In this case, the balanced equation is: H2 + Cl2 -> 2HCI This means that one molecule of hydrogen and one molecule of chlorine react to form two molecules of hydrochloric acid.

Answer:

x = 26.7

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan64° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{13}[/tex]

Multiply both sides by 13

13 × tan64° = x, thus

x ≈ 26.7

Answer:

x = 26.7 units

Step-by-step explanation:

1. Find the third side: 180 = 90 + 64 + A, where A is the unknown angle

A = 180 - 154, A = 26°

2. Law of sines: sinA/a = sin B/b, where A and B are angles on a triangle, and a and b are the angles' opposite sides.

Plug in: sin(26°)/13 = sin(64°)/x

Means-extremes + multiply: x = 13sin(64°)/sin(26°)

Simplify: x ≈ 26.7 units (It is better to put one equation straight into the calculator instead of doing it one at a time, since the answer will be more accurate.)

The distance between the kites will be 128.16 feet.

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

Given that;

Linda has 99 feet of string out to one kite and 112 feet out to the other kite.

And, The angle formed by the two strings is 39°.

Now,

Find the distance between the kites as;

Since, Linda has 99 feet of string out to one kite and 112 feet out to the other kite.

And, The angle formed by the two strings is 39°.

Let the distance between the kites = x

So, We can formulate as;

x² = (112)² + 99² - 2 × 112 × 99 cos 39°

Solve for x as;

x² = 12,544 + 9,801 - 22,176 × 0.267

x² = 22,345 - 5,921

x² = 16,424

x² = √16,424

x = 128.16

Thus, The distance between the kites will be 128.16 feet.

Answer:

a. The coordinates of the vertex are (2 , 3)

b. The focal length of the parabola is 8

c. The equation, in standard form, of the parabola is (y - 3)² = -8(x - 2)²

Step-by-step explanation:

* Lets revise the equation of a parabola  

- If the equation is in the standard form (y − k)² = 4p(x − h), then:

# Use the given equation to identify h and k for the vertex, (h , k)

# Use the value of k to determine the axis of symmetry, y = k

# Use h , k and p to find the coordinates of the focus, (h + p , k)

# Use h and p to find the equation of the directrix, x = h − p

# The endpoints of the focal diameter,  (h + p , k ± 2p)

# The focal length is I4pI

* Now lets solve the problem

∵ The parabola has focus at (0 , 3)

∵ The coordinates of its focus, (h + p , k)

∴ h + p = 0 ⇒ (1)

∴ k = 3

∵ Its directrix at x = 4

∵ The equation of the directrix, x = h − p

∴ h - p = 4 ⇒ (2)

- Add (1) and (2) to find h and p

∴ h + p + h - p = 0 + 4 ⇒ add the like terms

∴ 2h = 4 ⇒ divide both sides by 2

∴ h = 2

- Substitute the value of h in (1)

∴ 2 + p = 0 ⇒ subtract 2 from both sides

∴ p = -2

a. ∵ h = 2 and k = 3

∵ The vertex of the parabola is (h , k)

∴ The coordinates of the vertex are (2 , 3)

b. ∵ The focal length is I4pI

∵ p = -2

∴ The focal length = I4 × -2I = I-8I = 8

∴ The focal length of the parabola is 8

c. ∵ The equation in the standard form is (y − k)² = 4p(x − h)

∵ h = 2 , k = 3 , p = -2

∴ The equation is (y - 3)² = 4(-2)(x - 2)²

∴ The equation is (y - 3)² = -8(x - 2)²

∴ The equation, in standard form, of the parabola is (y - 3)² = -8(x - 2)²

Answer:

B. [tex]f(x)=0.2(x-2)^2+1[/tex]

Step-by-step explanation:

The equation of a parabola in the vertex form is given by:

[tex]f(x)=a(x-h)^2+k[/tex], where V(h,k) is the vertex of the parabola

This parabola opens upwards and has its vertex at: V(2,1)

The a-value must therefore be positive.

The function must be

[tex]f(x)=0.2(x-2)^2+1[/tex]

The correct option is B.

Answer:

17.25 km N37.9°E

Step-by-step explanation:

The way to solve this is to determine the vertical and horizontal distances traveled.

The bearing means 45° east of north.

Vertically, the car travels a distance of:

y = 3 + 15 cos 45°

y = 3 + 7.5√2

y ≈ 13.6

Horizontally, the car travels a distance of:

x = 15 sin 45°

x = 7.5√2

x ≈ 10.6

The total distance we find with Pythagorean theorem:

d = √(x² + y²)

d = √(10.6² + 13.6²)

d ≈ 17.25

The bearing from north we find with tangent:

tan θ = x / y

tan θ = 10.6 / 13.6

θ ≈ 37.9°

the square root of 108 is about 10.4 and since the negative symbol is on the outside of the square root symbol, the answer is -10.4

To eliminate 't' from the parametric equations X=6cos t and Y=3sin t, square both equations and substitute the resulting cos^2 t and sin^2 t values into the trigonometric identity equation sin^2 t + cos^2 t = 1. This results in the equation X^2 / 36 + Y^2 / 9 = 1, effectively eliminating 't' from the equations.

Eliminating the Parameter for X=6cos t and Y=3sin t

Our goal here is to eliminate the parameter 't' from the two given equations, which is a common task in parametric equations.

For such problems involving sin and cos, we can use the trigonometric identity sin^2 t + cos^2 t = 1. However, the provided equations don't directly represent sin t or cos t. To bring them in those forms, we start by squaring both equations.

Squaring X and Y yields: X^2 = 36cos^2 t and Y^2 = 9cos^2 t.

Next, we solve each equation for cos^2 t and sin^2 t separately.

cos^2 t = X^2 / 36 and sin^2 t = Y^2 / 9.

Substituting these values into the trigonometric identity equation, we get: X^2 / 36 + Y^2 / 9 = 1 which is the equation of an ellipse in x and y. Hence, 't' has been eliminated.

To eliminate the parameter x = 6 cos t and y = 3 sin t, you can express x in terms of y as x = cos(t) and substitute it into the equation y = 3 sin(t), resulting in y = 3 sin(arccos(x)).

To eliminate the parameter in this case, we need to express x in terms of y. We can start by dividing the equation X = 6 cos(t) by 6 to get x = cos(t). Then we can substitute this expression for x in the equation y = 3 sin(t) to get[tex]y = 3 sin(cos^(-1)(x)).[/tex]

Since [tex]cos^(-1)(x)[/tex]is the inverse of cosine, we can rewrite this as y = 3 sin(arccos(x)).

So, when we eliminate the parameter, we have the equation y = 3 sin(arccos(x)).
