Step-by-step explanation:

Hope my answer has helped you!

The angles are congruent meaning that you can set them equal to each other:

26 = 5x + 11

Now you can solve for x

26 - 11 = 5x + (11 - 11)

15 = 5x

15/5 = 5x/5

x = 3

Hope this helped!

The tickets she can buys N<5

We have given that

"Makayla has $8 to buy tickets at the school fair. each ticket costs $1.50"

Total number of money=cost for each ticket × (N)

can be written as,

[tex]$8 = (1.50/ticket)*N.[/tex]

Dividing both sides by ($1.50/ticket) results in

  [tex]N=\frac{8}{1.50/ticket}[/tex]

[tex]N=\frac{8}{1.50/ticket}\\\\N= 5 \frac{1}{3} tickets[/tex]

N=5.33

Therefore tickets she can buys N=5(1/3) or < 5.

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)).

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°

Answer:

25

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.)

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:

The series is 5 , 6 , 7 , 8 , 9 , 10 , 11

Step-by-step explanation:

* Lets revise the arithmetic series

- In the arithmetic series there is a constant difference between

 each two consecutive numbers

- Ex:

# 2  ,  5  ,  8  ,  11  ,  ……………………….  (constant difference is 3)

# 5  ,  10  ,  15  ,  20  ,  …………………………  (constant difference is 5)

# 12  ,  10  ,  8  ,  6  ,  ……………………………  (constant difference is -2)

* General term (nth term) of an Arithmetic series:

- If the first term is a and the common diffidence is d, then

 U1 = a  ,  U2  = a + d  ,  U3  = a + 2d  ,  U4 = a + 3d  ,  U5 = a + 4d

- So the nth term is Un = a + (n – 1)d, where n is the position of the

 number in the series

* Lets solve the problem

- Jeff wants to increase the number of miles he runs each day

∴ He will add the initial value by constant number each day

- He plans on increasing the number of miles he runs a day by 1

∴ The constant value is 1 mile

-  On the first day of training, Jeff runs 5 miles

∴ The first value is 5 miles

∴ The series is arithmetic

∵ a = 5 , d = 1

- He do that for the remainder of the week

∵ The week has 7 days

∴ The series has 7 terms

∵ The rule of the series is Un = a + (n - 1)d

∵ a = 5 and d = 1

∴ Un = 5 + (n - 1)(1)

∴ Un = 5 + n - 1

∴ Un = 4 + n ⇒ n is the position of the number

- Substitute n from 1 to 7 to find the series

∴ The series is 5 , 6 , 7 , 8 , 9 , 10 , 11
