Step-by-step explanation:

The highest common factor (HCF) is discovered by identifying all common factors of two integers and then picking the greatest one. The HCF of the given algebraic expressions is x³.

What is HCF?

The highest common factor (HCF) is discovered by identifying all common factors of two integers and then picking the greatest one. For example, the common factors of 8 and 12 are 1, 2, and 4. The greatest common factor is four.

The given expressions can be written in the factored form as shown below.

x³ = x · x · x

x⁶ = x · x · x · x · x · x

x⁷ = x · x · x · x · x · x · x

Now, the GCF from the factors can be written as shown below.

GCF = x · x · x = x³

Hence, the HCF of the given algebraic expressions is x³.

Clara and her family are vacationing in the Netherlands. They began a tour of the North Sea coastline at an elevation of

8 feet. By the end of the tour, their elevation had decreased by 5 feet. What was their elevation at the end of the tour?

Answers

Answer:

-13 feet

Step-by-step explanation:

The elevation of Clara and her Family at the end of the tour is the difference between their starting elevation of the change in elevation. Hence, their final elevation is - 13 feets

Given the Parameters :

Initial elevation = - 8 feets Decrease in elevation = 5 feets

Final elevation can be obtained thus :

Initial elevation - Change in elevation

Final elevation = -8 feets - (5 feets)

Final elevation = - 8 - 5 = - 13 feets

Therefore, their final elevation at the end of the tour is - 13 feets

How does the function represented in the table change over equal intervals? What
does this tell you about the type of function it is?

Answers

The answer to the question you are looking for is B

For equal intervals changing in the independent variable, the corresponding dependent value does not change by equal differences, so it is not linear. which is the correct answer would be option (B).

What is the Linear function?

A linear function is defined as an equation in which the highest exponent of the variable is always one.

The table is given in the question.

As per the given table,

The rate of change will be

During the first interval : (20-10)/(9-7) = 10/2

During the second interval : (30-20)/(11-9) = 10/2

During the third interval : (40-30)/(14-11) = 10/3

The corresponding dependent value does not vary by equal differences when equal intervals in the independent variable change, therefore it is not linear.

Hence, the correct answer would be an option (B).

Answer:

1

Step-by-step explanation:

I am assuming the question is asking which x value plugged into the function will give you a zero so

(-1)3 -8(-1)2 -23(-1)+30

so that simplyfiys to -1-8(1)+23+30

so that is -1-8+53

so -9+53

= 44

trying 3 we get

(3)3-8(3)2-23(3)+30

so that is 27 -72-69+30

and that is not zero

trying -10

we get

(-10)3-8(-10)2-23(-10)+30

which is -1000- 800+230+30

that is not zero so lastly trying  1 we get

(1)3-8(1)2-23(1)+30

which is 1-8-23+30

which is -7+7 which is zero

Selena is flying a kite as shown below. Use the measurements to find how long the kite string is.
16 feet
12 feet
feet

Answers

Answer:

20 feet

Step-by-step explanation:

In this case, you'd use pythagoras's theorem (a^2 + b^2 = c^2)

The hypotenuse is always = c, so you'd set up the equation like this:

16^2 + 12^2 = c^2, where you're solving for c (to find out the length of the kite string)

This equation simplifies to 256 + 144 = c^2

which further simplifies to 400 = c^2

to solve for c, we square root both sides so the c is isolated:

[tex]\sqrt{400} = \sqrt{c}[/tex]

20 = c

so the length of the kite string is 20 feet

The required length of the kite string will be 20 feet.

What is Pythagoras's theorem?

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

As per the question, we have to use Pythagoras's theorem

a² + b² = c²

Here hypotenuse = c,

Substitute the known values and we get

16² + 12² = c²,

Here c is the length of the kite string and simplifies the equation as:

256 + 144 = c²

c² = 400

c = √400

c = 20

Thus, the length of the kite string is 20 feet.
