Answer:

1/ 5^7

Step-by-step explanation:

5^-4 / 5^3 is the same as (5^-4 / 1) * (1/5^3)

5^-4 turns into 1 / 5^4

So you have 1/ (5^4 * 5^3)

When multiplying two of the same numbers you add the exponents giving you 1/ (5^7)

Answer:

less likely

Step-by-step explanation:

In the question, we are to choose which of the options best fit into blank space.

Talking about probabilities, the probability of events ranges from 0 to 1. With 1 being the highest value the probability of an event can take while 0 is the lowest value the probability of an event can take. The probability of an event can neither be negative, nor greater than 1. It lies between 0 and 1

Now, the closer a probability is to 1, the greater the likelihood of that particular event happening. Events having probabilities closer to 1 are more likely to occur than those farther away from 1 or closer to zero.

In this question, 0.9 is a greater value compared to 0.8. Thus, an event of probability 0.9 is more likely to happen compared with an event with probability of 0.8

In other words, an event with probability 0.8 is less likely to occur compared with an event with a probability value of 0.9

Answer:

Using distance formula :

AB = [tex]\displaystyle \sqrt{(10-1)^2 + (3 - 7)^2}[/tex]

AB = [tex]\sqrt{81 + 16}[/tex]

AB = 9.85 units

Answer:

[tex]}\frac{\sqrt{2} }{2}[/tex] or 0.707

Step-by-step explanation:

cos(315) is equivalent to cos ([tex]\frac{7\pi }{4}[/tex])

You can look at the unit circle to find the cos value for this. Keep in mind that cos is the x value of the corresponding coordinate.

Answer:

y = 1x - 5

Step-by-step explanation:

It looks like the form that they want is Slope Intercept Form. :(

y = mx + b

The two points on the line are (5, 0) and (0, -5)

The slope is 1

The y - intercept is -5

y = 1x - 5

Answer:

1 * x - 5

Step-by-step explanation:

Y = mx + b

the equation will be 1 * x - 5

Answer:

4x² + 12x + 9

Step-by-step explanation:

Simplify. Expand:

(2x + 3)² = (2x + 3)(2x + 3)

Use the FOIL method to solve.

FOIL =

First

Outside

Inside

Last

Multiply:

(2x)(2x) = 4x²

(2x)(3) = 6x

(3)(2x) = 6x

(3)(3) = 9

Combine like terms:

4x² + 6x + 6x + 9 = 4x² + (6x + 6x) + 9 = 4x² + 12x + 9

4x² + 12x + 9 is your answer.

Answer:

4x^2+12x+9

Step-by-step explanation:

Answer:

3800

Step-by-step explanation:

342 is the 9 percent that have shown up. If you divide that by nine you would get on percent of the total which comes out to be 38. so you multiply 38 by 100 and get 3800 which is 100% of the tickets sold.

Answer:

560 downloads of standard version downloads.

Step-by-step explanation:

Let there were number of standard version of downloads = x

and number of high quality version of downloads = y

There were total 950 downloads of the both type of songs.

x + y = 950 -----(1)

Size of the standard version songs = 2.8 MB

and the size of the high quality version songs = 4.4 MB

Total download size = 3284 MB

2.8x + 4.4y = 3284

7x + 11y = 8210 -----(2)

Multiply equation (1) by 11 (-) equation (2)

(11x + 11y) - (7x + 11y) = 10450 - 8210

4x = 2240

x = 560

There were 560 downloads of the standard version downloads.

D. 4.5%.

Step-by-step explanation:

Interest earned in 6 months = 572.6 - 560 = $12.60.

As a percentage this is (12.60 * 100) / 560

= $ 2.25%.

So the annual interest is 2 * 2.25

= 4.5%.

Answer:

-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1

(would really, reallly appreciate the brainliest)

Step-by-step explanation:

2x+9 < 9

can be rewritten as

2x < 0

and therefore

x < 0

the other inequality states that x hat to be bigger then -12

so all integers that satisfy -12 < x < 0 are in the set we search, but be aware that -12 and 0 don't fall into this set, bc -12 for example isn't bigger than -12

Answer:

The integers that satisfy both inequalities are -5, -6, -7, -8, -9, -10 and -11.

Step-by-step explanation:

Firstly, you have to solve the inequality :

[tex]2x + 9 < 0 [/tex]

[tex]2x < - 9[/tex]

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

[tex]x < - 4.5[/tex]

Next, given that x is greater than -12 but smaller than -4.5 so the inequality for x is :

[tex] - 12 < x < - 4.5[/tex]

Integer is a positive or a negative number but 'cannot be written in the form of decimal'. So the integers that satisfy both inequalities are :

[tex] - 12 < x < - 4.5[/tex]

[tex]x = - 11, - 10, - 9, - 8, - 7, - 6, - 5[/tex]

Well, because this is a khan academy question i guess ill be safe to answer it.

0 is in the domain

4 is in the domain

5 is NOT in the domain.

Step-by-step explanation:

If you plug in 5, you are left with

[tex]\frac{4}{5 - 5}[/tex] = [tex]\frac{4}{0}[/tex] = undefined

However, if you plug in any other value in that list, you are left with a number.

Remember, it isn't in the domain if the number is imaginary (like square root of a negative number) or the answer results in an undefined :)

Answer:

b) 29 of 50 for science

Step-by-step explanation:

We would be finding out his best results by calculating the percentage of his scores in the various exams he took.

a) 34 of 60 for history

34/ 60 × 100 = 56.67%

b) 29 of 50 for science

29/50 × 100 = 58%

c) 39 of 70 for Music

39/70 × 100 = 55.7%

d) 44 of 80 for Math

44/80 × 100 = 55%

Looking at the percentage of his scores in various subject in his exams, the subject with the highest percentage is the subject where he had the best result.

That subject with 58% = 29/50 for science.

Therefore, his best results is option b) 29 of 50 for science.

Answer:

y = - [tex]\frac{1}{2}[/tex] x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line

m = [tex]\frac{0-2}{4-0}[/tex] = [tex]\frac{-2}{4}[/tex] = - [tex]\frac{1}{2}[/tex]

note the line crosses the y- axis at (0, 2) ⇒ c = 2

y = - [tex]\frac{1}{2}[/tex] x + 2 ← equation of line

Answer:

[tex] \boxed{B. \: 5 {x}^{6} + 5 {x}^{5} + 8 {x}^{2} - x + 2} [/tex]

Step-by-step explanation:

[tex] = > (2 {x}^{6} + 8 {x}^{2} - x + 1) + (3 {x}^{6} + 5 {x}^{5} + 1) \\ \\ = > 2 {x}^{6} + 8 {x}^{2} - x + 1 + 3 {x}^{6} + 5 {x}^{5} + 1 \\ \\ = > 2 {x}^{6} + 3 {x}^{6} + 5 {x}^{5} + 8 {x}^{2} - x + 1 + 1 \\ \\ = > 5 {x}^{6} + 5 {x}^{5} + 8 {x}^{2} - x + 2[/tex]

The polynomial representing the sum is [tex]5x^6 + 5x^5 + 8x^2 - x + 2[/tex] (Option B).

The polynomial that represents the sum of the two polynomials is:

[tex](2x^6 + 8x^2 - x + 1) + (3x^6 + 5x^5 + 1)[/tex]

Combining like terms, we can simplify the expression:

[tex]2x^6 + 3x^6 + 8x^2 + 5x^5 - x + 1 + 1[/tex]

Now, combining the like terms further:

[tex]5x^6 + 5x^5 + 8x^2 - x + 2[/tex]

Therefore, the polynomial that represents the sum is:

[tex]5x^6 + 5x^5 + 8x^2 - x + 2[/tex] (Option B).
