I need to fill in the blanks for this equation and I cant figure it out

Answers

Answer:

1. +12x and 15

2. 14x

3. 2

Step-by-step explanation:

Step 1: Distribute -3

To distribute -3, you would multiply both -4x and -5 by -3, changing them to 12x and 15

Step 2: Combine 12x and 2x

Then you would combine like terms, meaning that you would add 12x and 2x, creating 14x.

Step 3: Combine 15 and -13

You would finish combining like terms by adding 15 to -13, creating 2

From a hot air balloon 2,500ft above the ground you see a clearing whose angle of depression is at 25 degrees. What is the horizontal distance form the clearing to the nearest feet

Answers

9514 1404 393

Answer:

5361 feet

Step-by-step explanation:

The tangent of the angle is the ratio of vertical distance to horizontal.

tan(25°) = (vertical distance)/(horizontal distance)

horizontal distance = (2500 ft)/tan(25°) ≈ 5361 feet

Prove that sin(3x)/sin(x)·cos(x) = 4cos(x)-sec(x)

Answers

Here is a huge hint:

sin(3x) = 3 sin (x) - 4(sin x)^3

sec (x) = 1/sin(x)

Take it from here.

The expression {4 cos(x) - sec(x)} is equivalent to {sin(3x)/sin(x) cos(x)} is proved below.

What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.

Given is the equation -

sin(3x)/(sin(x)·cos(x)) = 4cos(x) - sec(x)

We have the following equation -

{sin(3x)/(sin(x)·cos(x)} = 4cos(x) - sec(x)

Now, we know -

sin3x = 3 sin x - 4 sin³x

So, we can write -

(3 sin x - 4 sin³x)/(sin(x)·cos(x) = 4cos(x) - sec(x)

sin(x) (3 - 4sin²x) / sin(x) cos(x) = 4cos(x) - sec(x)

(3 - 4sin²x)/cos(x) = 4cos(x) - sec(x)

(3 - 4sin²x) = cos(x){4 cos(x) - 1/cos(x)}

(3 - 4sin²x) = 4cos²x - 1

3 + 1 = 4cos²x + 4sin²x

4 = 4(cos²x + 4sin²x)

4 = 4

1 = 1

LHS = RHS

Therefore, it is proved that the expression {4 cos(x) - sec(x)} is equivalent to {sin(3x)/sin(x) cos(x)}.

Brenda and Shayna are selling flower bulbs for a school fundraiser. Customers can
buy bags of windflower bulbs and packages of crocus bulbs. Brenda sold 5 bags of
windflower bulbs and 5 packages of crocus bulbs for a total of $145. Shayna sold 3
bags of windflower bulbs and 5 packages of crocus bulbs for a total of $121. Find
the cost of one bag of windflower bulbs.

Answers

Given :

Customers can buy bags of windflower bulbs and packages of crocus bulbs. Brenda sold 5 bags of windflower bulbs and 5 packages of crocus bulbs for a total of $145.

Shayna sold 3 bags of windflower bulbs and 5 packages of crocus bulbs for a total of $121.

To Find :

The cost of one bag of windflower bulbs.

Solution :

Let, cost of one bag of windflower bulbs and crocus bulbs is x and y.

Converting given statement to mathematical equation, we get :

5x + 5y = 145

x + y = 29 ...1)

and

3x + 5y = 121 ...2)

Solving equation 1 and 2, we get :

3( 29 - y ) + 5y = 121

87 - 3y + 5y = 121

2y = 34

y = 17

and x = 12

Therefore, cost of one bag of windflower bulbs is $12 .

Hence, this is the required solution.

Write a series of rigid motions that transform pentagon ABCDE to pentagon A′B′C′D′E′

Answers

Answer:

We need the following three rigid motions:

i) Reflection around y-axis, ii) Translation three units in the -y direction, iii) Translation four units in the -x direction.

Step-by-step explanation:

We need to perform three operations on pentagon ABCDE to create pentagon A'B'C'D'E':

i) Reflection around y-axis:

[tex](x',y') = (-x,y)[/tex] (Eq. 1)

ii) Translation three units in the -y direction:

[tex](x'',y'') = (x', y'-3)[/tex] (Eq. 2)

iii) Translation four units in the -x direction:

[tex](x''',y''') = (x''-4, y'')[/tex] (Eq. 3)

We proceed to proof the effectiveness of operations defined above by testing point D:

1) [tex]D(x,y) = (-1, 4)[/tex] Given.

2) [tex](x',y') = (1,4)[/tex] By (Eq. 1)

3) [tex](x'',y'') = (1, 1)[/tex] By (Eq. 2)

4) [tex]D'(x,y) = (-3,1)[/tex] By (Eq. 3)/Result

Answers

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle

13x - 11 + 4x + 1 = 18x - 15 add like terms

17x - 10 = 18x - 15

- 10 + 15 = 18x - 17x

5 = x

measure of angle A 13x - 11 ➡ 13 × 5 - 11 = 54°

measure of angle B 4x + 1 ➡ 4 × 5 + 1 = 21°

measure of angle C 18x - 15 ➡ 18 × 5 - 15 = 75°

Which best explains why all equilateral triangles are similar?

all equilateral triangle’s can be mapped onto each other using dilations

all equilateral triangle can be mapped onto each other using rigid transformations

all equilateral triangles can be mapped onto each other using combinations of dilations and rigid transformations

all equilateral triangles are congruent and therefore similar with side links and a 1:1 ratio

Answers

Answer:

Step-by-step explanation:

I hope this helps you out!

Answer:

all equilateral triangle’s can be mapped onto each other using dilations.

Step-by-step explanation:

Because you can dilate or increase the size and scale the triangle about a certain point so if you do it correctly, this can be done with just a dilation.

Also an equilateral triangle is defined as a triangle where all the sides are congruent in length. This does not mean that all equilateral triangles are congruent (Do not get confused with D) to each other since size is the undefined variable so all equilateral triangles are proportional which means that they always have a ratio between them depending on the scale factor.

For example, let's say I have an equilateral triangle with a side length of 2, this means that all the sides must have a length of 2, but I can also have an equilateral triangle with a side length of 3, which means that all the sides will have that length for that triangle.

2 ≠ 3, but there is always a conversion factor between the side lengths. In this case a scale factor of 3/2 from the triangle with a side length of 2 to the one with a side length of 3. And a scale factor of 2/3 going from the triangle with a side length of 3 to the triangle with a side length of 2. Because all the sides are congruent, the angles must all be 60° degrees because individual side proportions defined by trigonometry are based on angles and sides. Thus, the angles are also affected due to the change in ratio.

In △XYZ, suppose XY < XZ. Which inequality relates two angles in △XYZ?

Answers

Answer:

m∠Z < m∠Y

Step-by-step explanation:

m∠Z < m∠Y

The inequality that relates the two angles in triangle XYZ is m∠Z < m∠Y

From the question, we have:

Triangle XYZSide length XY is less than side length XZ

This means that, the angle at point Y is greater than the angle at point Z

i.e. m∠Y > m∠Z

Rewrite the inequality as:

m∠Z < m∠Y

Hence, the inequality that relates the two angles in triangle XYZ is m∠Z < m∠Y
