At most means it can either equal 20 or be less than 20.

On a number line, there would be a closed circle on the number 20 and the area to the left of 20 would be shaded.

Answer:

( 8.5 , 6.5 )

Step-by-step explanation:

Midpoint formula = ( x₁ + x₂ / 2 ) , ( y₁ + y₂ / 2 )

x₁ = 4

x₂ = 13

y₁ = 10

y₂ = 3

Midpoint = ( 4 + 13 / 2 ) , ( 10 + 3 / 2 )

Midpoint = ( 17 / 2 ) , ( 13 / 2 )

Midpoint = 8.5 , 6.5

(x+2)(x^2+1)

=(x+2)(x+1)(x+1)

Answer:

( x + i)(x -i) ( x +2).

Step-by-step explanation:

Given  : x³ + 2x² +x +2.

To find :  complete factorization of the polynomial below.

Solution : We have given x³ + 2x² +x +2.

On taking common x² from first two terms and 1 from last two terms .

x² ( x +2) +1 (x +2).

On grouping

(x²  +1) ( x +2).

Now factor of (x²  +1) become ( x + i)(x -i) in complex form .

Factors are  ( x + i)(x -i) ( x +2).

Therefore,  ( x + i)(x -i) ( x +2).

The expression [tex]\(4^5/3\)[/tex] is indeed equivalent to[tex]\(\sqrt[3]{4^5}\)[/tex].

The correct option is (a).

To demonstrate that the expression[tex]\(4^5/3\) is equivalent to \(\sqrt[3]{4^5}\)[/tex], we can apply the following properties:

1. Radical to Exponent Property:

  - The expression [tex]\(\sqrt[3]{4^5}\) can be rewritten as \(4^{5/3}\)[/tex].

  - This property allows us to convert a radical expression to an exponent expression by raising the base to the reciprocal of the index of the radical.

2. Exponent to Radical Change Property:

  - The fraction exponent [tex]\(5/3\)[/tex] can be expressed as a radical: [tex]\(\sqrt[3]{4^5}\)[/tex].

down step-by-step:

1. Start with the given expression: [tex]\(4^5/3\)[/tex].

2. Apply the **Radical to Exponent Property: [tex]\[4^5/3 = 4^{5/3}\][/tex]

3. Now, express the fraction exponent as a radical:

[tex]\[4^{5/3} = \sqrt[3]{4^5}\][/tex]

Therefore, the expression [tex]\(4^5/3\)[/tex] is indeed equivalent to[tex]\(\sqrt[3]{4^5}\)[/tex].

It means Option C) and D) is incorrect.

From the given graph , it can be observe that quadrilateral R'S'T'U' (image) is larger than the RSTU (pre-image) .

It means the scale factor should be greater than 1. [∵ Scale factor for enlargement is k>1]

Then, Option B is also incorrect.

Answer: [tex]x=7[/tex]

Step-by-step explanation:

By the Intersecting Secants Theorem, we know that:

[tex](5)(x+5)=(6)(6+4)[/tex]

Having this, we can find the value of "x" by solving for "x":

Applying Distributive property:

[tex](5)(x+5)=(6)(24)\\5x+25=60[/tex]

Subtract 25 from both sides of the equation:

[tex]5x+25-25=60-25\\5x=35[/tex]

And finally dviding both sides of the equation by 5, we get:

[tex]\frac{5x}{5}=\frac{35}{5}\\x=7[/tex]

Answer:

-8/5

Step-by-step explanation:

The thing that makes lines different from other kinds of curves is their constant rate of change. We call this rate of change slope, and you usually see it represented with the letter m. We measure it as the rate our y-coordinate changes for some amount our x-coordinate changes.

We're given the two points (-1, 4), and (4, -4). From that first point to the second one, our x-coordinate increases by 5, while our y-coordinate decreases by 8, so our change in y is -8 for every 5 in the positive x direction, and we'd write our slope as

m = -8/5

Remember that 9! = 7! (8)(9)

write Substitute

7!(8)(9) for 9!

7!(8)(9)/ 7!= (8)(9)= 72

Answer: 72

Step-by-step explanation:

By definition, it is important to know that the factorial of a non-negative integer "n" is the product of all positive integers less than or equal to "n".  This is expressed with an exclamation symbol (!):

[tex]n![/tex]

Then, the rule for this is the following:

[tex]n! = n *(n-1)![/tex]

Therefore, knowing this, you can evalute [tex]\frac{9!}{7!}[/tex] as following:

 [tex]\frac{9*8*7*6*5*4*3*2*1}{7*6*5*4*3*2*1}=\frac{362,880}{5,040}=72[/tex]

the concept is to find the value of h

Answer:

it is an algebraic expression (answer is h = -2 )

Simplify the expression

(Combine Like Terms)

(−4h)+(−6+15)=17

−4h + 9 = 17

Step 2: Subtract 9 from both sides.

−4h + 9 − 9 = 17 − 9

−4h=8

Answer:

The length of the line segment is 13 units

Step-by-step explanation:

The line segment joining the two points is horizontal since the y co-ordinate is the same.

For a horizontal line, the length of the line segment is simply the difference between the x co-ordinate values.

In this case we have;

7 - (-6) = 7 + 6 = 13

Therefore, the length of the line segment is 13 units

Answer:

13 units

Step-by-step explanation:

We want to find the length  of the line segment with endpoints (-6,-8) and (7,-8).

Observe that, the y-coordinates are the same.

We can quickly use the absolute value method to find the required length.

According to this method the length of the line segment with endpoints (-6,-8) and (7,-8) is the absolute value of the difference between the x-values.

[tex]|7--6|=|7+6|=|13|=13[/tex]

The length of the line segment is 13 units.

Answer:\

The answer is A :) I took the assignment

Answer:

see explanation

Step-by-step explanation:

Given

[tex]\frac{x^2-9}{x^2-3x}[/tex]

Factorise the numerator/denominator

x² - 9 = (x - 3)(x + 3) ← difference of squares

x² - 3x = x(x - 3) ← common factor of x

The fraction simplifies to

[tex]\frac{(x-3)(x+3)}{x(x-3)}[/tex] ← cancel (x - 3) on numerator/denominator

= [tex]\frac{x+3}{x}[/tex]

In order to answer this, you have to have the unit of measurement and an illustration.

We are looking for the number of pencils per hour.

[tex]0.178571428571 \frac {penc} {g} * 64,512 \frac {g} {h} = 11,520 \frac {pen} {h}[/tex]

Answer:

about 32.9

Step-by-step explanation:

By looking at the triangle, you can see that there is both an angle and a side provided. This allows you to use trigonometry (sin, cos, tan). You have to use tan to find the answer since it is used when you have either the opposite side or adjacent side and are solving for one of them. You take the tangent of the angle and set it equal to the opposite over the adjacent (see image attached).

I hope this helps.

Also sorry that the image is the wrong way, but it wouldn't let me attach it the right way.

QUESTION 1

Given a right triangle, the unknown side is opposite to the 35° angle.

The side adjacent to this angle is 47 units.

We use the tangent ratio to get:

[tex] \tan(35 \degree) = \frac{opposite}{adjacent} [/tex]

[tex] \tan(35 \degree) = \frac{x}{47} [/tex]

[tex] x = 47\tan(35 \degree)[/tex]

[tex]x = 32.9units[/tex]

to the nearest tenth.

QUESTION 2

The given angle is 47°

The opposite side is x units.

The adjacent side is 40 units.

We again use the tangent ratio to obtain:

[tex] \tan(47 \degree) = \frac{x}{40} [/tex]

[tex]x = 40\tan(47\degree) [/tex]

[tex]x = 42.9units \: to \: the \: nearest \: tenth[/tex]

Answer:

[tex]m=0.002kg[/tex]

Step-by-step explanation:

The given formula is:

[tex]E=mc^2[/tex]

Divide both sides by [tex]c^2[/tex].

[tex]\implies \frac{E}{c^2}=\frac{mc^2}{c^2}[/tex]

Cancel out the common factors to get;

[tex]\implies \frac{E}{c^2}=m[/tex]

[tex]m=\frac{E}{c^2}[/tex]

When [tex]E=1.8\times10^{14}J[/tex] and [tex]c=300,000,000ms^{-1}[/tex], then

[tex]m=\frac{1.8\times10^{14}}{300,000,000^2}[/tex]

This simplifies to

[tex]m=0.002kg[/tex]

Answer:

Option C is correct.

Step-by-step explanation:

P(A or B) represents  that event A has occurred or event B has occurred or both events A and B are happening.

We are given P(A or B) = 0.60 or 0.60/100 = 60%

So, Option C The probability that a customer buys either a taco or a drink is 60% is correct.

Answer: Option C

Step-by-step explanation:

For two events A and B, P(A or B) represents the probability that event A occurs, or event B occurs.

In this case, event A represents a customer buys a taco and event B represents a customer buys a drink. We know that

[tex]P (A\ or\ B) = 0.60[/tex]

So this means that the probability that a customer buys either a taco or a drink is 60%

The answer is the option C

Answer:

Neither function A nor function B has an x-intercept.

Step-by-step explanation:

Function A has a y-intercept at (0, 5).

Function B is defined for negative numbers as well as positive numbers, but not for x=0.

These observations eliminate all answer choices but the first one.

The statement that best compares the two functions is; Neither function A nor function B has an x-intercept.

A y-intercept is the point where x = 0. Now, for function A we can see that when x = 0, y = 5. Thus, it has a y-intercept.

However, we are not given the point where y = 0 which is x-intercept. Thus, function A does not have an x-intercept.

Formula for Function B is y = 4/x.

This function does not have an x-intercept because at x = 0, the function is undefined.
