The measures of each exterior angle in a regular hexagon is (4x + 15)°. Find the value of x. Show equations and all work that leads to your answer.

...?

Answers

Sum of exterior angle of a polygon is 360°
A regular hexagon has 6 equal exterior angles.
6(4x + 15) = 360
4x + 15 = 360/6 = 60
4x = 60 - 15 = 45
x = 45/4 = 11.25
x = 11.25

can someone explain how to find two positive numbers such that their product is 192 and the sum of the first plus three times the second is a minimum?

Answers

Let the two numbers be y and x, then
xy = 192
y = 192/x
dy/dx = -192/x^-2 . . . (1)

Sum (S) = y + 3x
If the sum is minimum, then
dS/dx = dy/dx + 3 = 0
dy/dx = -3

From (1), -192/x^2 = -3
3x^2 = 192
x^2 = 192/3 = 64
x = sqrt(64) = 8
y = 192/8 = 24

The two positive numbers are 8 and 24.

What unit of measurement would Guatemalans typically use to measure the weight of flour?

Answers

In general, Guatemalans also use the metric system, but also some traditional units of measurement (that come from Spain) and influence from US English units. Among the Guatemalan units of measurement some are based on old Spanish units. The libra, arroba, quintal and garrafón units of weight and volume. Guatemalans use also measures like spoons and cups. Therefore, when they weigh the measure of flour, they are using either the ibra, arroba, quintal and garrafón units. Hope this helps.

Consider the equation v + 4 + v = 8. What is the resulting equation after the first step in the solution?

a. v +4 = 8 – v
b. v +4 = 8
c. 4 + v = 8 – v
d. 2v + 4 = 8

Answers

The first step is to group like terms on each side of the equation. This would give you (v + v) + 4 = 8. There is no point in writing v + v as such, so 2v + 4 = 8 would be better. This is equation d.

d. 2v + 4 = 8.

Answer:

The resulting equation after the first step is 2v+4=8

d is the correct option

Step-by-step explanation:

We have been given the equation v + 4 + v = 8. In order to solve it for v, we'' perform the below mentioned steps.

Add the like terms in the left hand sideSubtract 4 to both sides of the equationFinally divide both sides by 2

Hence, in the first step, we can group the like terms and combine. In the left hand side v and v are like terms and hence, we can add them

On adding v and v we get 2v

Thus, we have

[tex]v+v+4=8\\2v+4=8[/tex]

Thus, the resulting equation after the first step is 2v+4=8

f(x)=2x*e^2x. find lim of f(x) as x--> - infinity and +infinity ...?

Answers

I am assuming it is f(x)=2x e^2x
2x times e raised to the 2x power, and not 2 times e raised to the 2x**

as it approaches infinity, your f(x) --> infinity
we can see by inspection, as 2x will approach inf, and e^(2x) will approach infinity even faster.
inf x inf = inf

as it approaches neg infinity, your f(x) --> 0
we can see by inspection, as 2x will approach neg inf, and e^(2x) will approach zero.
- inf x 0 = - 0

The minimum(or maximum) is given when the derivative = 0
Using the product rule,
f ' (x) = 2e^(2x) + 4x e(2x)
f ' (x) = 2e^(2x) ( 1 + 2x )
We find the roots
2e^(2x) will never equal 0
1 + 2x = 0, x = -1/2

The minimum value will be when x = -0.5

How are rigid transformations used to justify the SAS congruence theorem?

Answers

(Refer to the diagram in the attached photo.)

In this diagram there is defined two Sides and an Angle in between (SAS).

Notice how there are two loose endpoints in the diagram. A single line segment can be drawn connecting the endpoints, forming a unique triangle.

If the original diagram is transformed, the dimensions and angles formed by the third line segment remains the same relative to the first two.

Therefore, if two triangles have the same SAS configuration, then they are congruent.

The method in which rigid transformations used to justify the SAS congruence theorem is given.

What is rigid transformation?

A rigid transformation (also called an isometry) is a transformation of the plane that preserves length. In a rigid transformation the pre-image and image are congruent (have the same shape and sizes).

We are given that;

Theorem is SAS

Now,

The SAS congruence theorem states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent. To prove this theorem using rigid transformations, we can start with two distinct triangles that have a pair of corresponding congruent sides and a corresponding congruent included angle23. Then we can use a translation to move one triangle so that its congruent side matches the other triangle’s congruent side. Next, we can use a rotation to align the congruent angles of both triangles. Finally, we can use another translation to move the second congruent side of one triangle to match the second congruent side of the other triangle. By doing these rigid transformations, we have shown that one triangle can be mapped onto the other triangle exactly, which means they are congruent

Therefore, by the transformations the answer will be given above.

the square root of C=339
so diagonally from her house to the point of 45south and 336east is 339meters

Alice's distance from her home is 339 meters.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that Alice leaves her house and walks to school she walks 45 meters south and 336 meters east.

We can write the Alice's distance from her home as -

{x} = √(45)² + (336)²

{x} = √(2025 + 112896)

{x} = 339 meters

Therefore, Alice's distance from her home is 339 meters.

For spring break this year your family decided to visit Michigan, but it snows the first weekend you are there. You decide to make a snowman. If the bottom ball is 3 feet across, the middle ball is 2 feet across, and the top is 1 foot across, how much snow is needed to build the whole snowman? Round your answer to the nearest cubic foot.
A)
19 cubic feet of snow
B)
31 cubic feet of snow
C)
511 cubic feet of snow
D)
1022 cubic feet of snow ...?

Answers

Answer:

Step-by-step explanation:

Final answer:

To find the amount of snow needed to build the snowman, we need to calculate the volume of each ball and then add them together. The total volume is 18.84 cubic feet, rounded to 19 cubic feet.So,Option A.19 cubic feet of snow is correct.

Explanation:

To find how much snow is needed to build the whole snowman, we need to calculate the volume of each ball and then add them together. The volume of a sphere can be found using the formula V = (4/3) * pi * r³, where r is the radius of the sphere.

The bottom ball has a diameter of 3 feet, so the radius is 3/2 = 1.5 feet. The volume of the bottom ball is (4/3) * 3.14 * (1.5³) = 14.13 cubic feet.

The middle ball has a diameter of 2 feet, so the radius is 2/2 = 1 foot. The volume of the middle ball is (4/3) * 3.14 * (1³) = 4.19 cubic feet.

The top ball has a diameter of 1 foot, so the radius is 1/2 = 0.5 feet. The volume of the top ball is (4/3) * 3.14 * (0.5³) = 0.52 cubic feet.

The total volume of the snowman is 14.13 + 4.19 + 0.52 = 18.84 cubic feet. Therefore, the answer is 19 cubic feet of snow.

in DEF DE=17 m angle =32 Find DF nearest tenth

Answers

Since we are asked to find DF, and we are given an angle and the side opposite to it, we can use the sine function to find DF.
let x be the length of side DF.

sin(32)= 17/x
x= 17 / sin(32)
x= 32.08

approximately 32.1

Answer:

(A) 32.1

Step-by-step explanation:

It is given that in ΔDEF, DE=17 and m∠F=32, thus

Using the trigonometry, we have

[tex]sinx=\frac{Perpendicular}{Hypotenuse}=\frac{DE}{DF}[/tex]

⇒[tex]sin32^{\circ}=\frac{17}{DF}[/tex]

⇒[tex]DF=\frac{17}{sin32^{\circ}}[/tex]

⇒[tex]DF=\frac{17}{0.529}[/tex]

⇒[tex]DF=32.1[/tex]

Therefore, the value of DF is 32.1.

Hence option A is correct.
