Answer:

Aonnalin, great name  :)  answer as below

Step-by-step explanation:

They tell us to use slope-intercept form.   This is something you will just have to remember  y = mx+b    

It is confusing b/c there is the other one, the point-slope formula too.  but just remember both and know that the point-slope one is to get to the slope-intercept one.    y-y1 = m(x-x1)  

m= slope

m = (y2-y1) / (x2-x1)

P1= (0,7)  in the form (x1,y1)

P2 =(8,-2) in the form (x2,y2)

m = -2-7 / 8-0

m = -9 / 8

now that we have the slope, just use either point with the point-slope

y-7 = (-9/8)(x-0)

y-7 = -9x/8

y = -9x/8 + 7

y = \(\frac{-9}{8}\) X + 7

Answer:

14 and 17

Step-by-step explanation:

x+y=41

y=2x-1

x+(2x-1)=41

3x-1=41

3x=42

x=14

y=2(14)-1=27

Step-by-step explanation:

Step 1:  Make a system of equation

The sum of two numbers is 41

    x        +        y        =        41

The larger number is one less than twice the smaller number.

    x                =                2y               -                1

Step 2:  Substitute x from the second equation into the first

\(x + y = 41\)

\((2y - 1) + y = 41\)

\(3y - 1+ 1 = 41 + 1\)

\(3y/3 = 42 / 3\)

\(y = 14\)

Step 3:  Substitute y into the second equation

\(x = 2y - 1\)

\(x = 2(14) - 1\)

\(x = 28 - 1\)

\(x = 27\)

Answer:  \(x = 27, y = 14\)

Answer:

a) 79.6

b) 437.8

Step-by-step explanation:

First, you have to do 318.4/4 to find the rate she goes in the duration of an hour. The rate is 79.6, which means she travels at a rate of 79.6 kilometers per hour.

Then, you have to find the distance she takes to travel in 5.5 hours, so you have to do 5.5*79.6 which is 437.8.

So, Hannah travels 437.8 kilometers in 5.5 hours.

Vertical Angle Theorem

30=6x

5=x

Answer:

x=5

Step-by-step explanation:

Hello! No worries, Geometry is very confusing.

There are several proofs and theorems to use when trying to prove an angle size. In this picture, we see two lines intersecting, forming an intersection point with two similar looking angles.

With the Vertical Angles Theorem, it explains that when two lines intersect such as shown here, the angle on the vertical side of the original angle are both equal to the same number and is identical. Similarly, using this theorem we know that the unnamed angles (the big ones) are identical too, as they are vertical sides of each other.

Now we know the angle 6x and 30 degrees are equal to each other. So how do we solve x?

We can solve for x by making it equal to each other, signaling that you understand the Vertical Angle Theorem and stating that those two angles are equal to each other.

6x=30            Divide by 6 both sides to isolate the x varianle

x=5

Therefore, x is equal to 5.

Answer:

There are 68,640 different ways the runners can finish first, second, and third in the race.

Concept of Permutations

The number of different ways the runners can finish first, second, and third in a race can be calculated using the concept of permutations.

Brief Overview

Since there are 42 runners competing for the top three positions, we have 42 choices for the first-place finisher. Once the first-place finisher is determined, there are 41 remaining runners to choose from for the second-place finisher. Similarly, once the first two positions are determined, there are 40 runners left to choose from for the third-place finisher.

Calculations

To calculate the total number of different ways, we multiply the number of choices for each position:

42 choices for the first-place finisher × 41 choices for the second-place finisher × 40 choices for the third-place finisher = 68,640 different ways.

Concluding Sentence

Therefore, there are 68,640 different ways the runners can finish first, second, and third in the race.

The number of keys required to fully implement a symmetric algorithm with 10 participants is: 45 (Option C)

Symmetric encryption or Algorithm is a kind of encryption that uses a single key (a secret key) to encrypt and decode electronic data.

The key must be exchanged between the organizations communicating using symmetric encryption so that it may be utilized in the decryption process.

The formula that determines the number of keys necessary for a symmetric algorithm is given as;

The inflection point of f(t) is approximately t = 3.73.

(a) To determine if the function f(t) = -0.425t^3 + 4.758t^2 + 6.741t + 43.7 is increasing or decreasing, we need to find its derivative and examine its sign.

Taking the derivative of f(t), we have:

f'(t) = -1.275t^2 + 9.516t + 6.741

To determine the sign of f'(t), we need to find the critical points. Setting f'(t) = 0 and solving for t, we have:

-1.275t^2 + 9.516t + 6.741 = 0

Using the quadratic formula, we find two possible values for t:

t ≈ 0.94 and t ≈ 6.02

Next, we can test the intervals between these critical points to determine the sign of f'(t) and thus the increasing or decreasing behavior of f(t).

For t < 0.94, choose t = 0:

f'(0) = 6.741 > 0

For 0.94 < t < 6.02, choose t = 1:

f'(1) ≈ 14.982 > 0

For t > 6.02, choose t = 7:

f'(7) ≈ -5.325 < 0

From this analysis, we see that f(t) is increasing on the intervals (0, 0.94) and (6.02, ∞), and decreasing on the interval (0.94, 6.02).

(b) To find the inflection point of f(t), we need to find the points where the concavity changes. This occurs when the second derivative, f''(t), changes sign.

Taking the second derivative of f(t), we have:

f''(t) = -2.55t + 9.516

Setting f''(t) = 0 and solving for t, we find:

-2.55t + 9.516 = 0

t ≈ 3.73

Therefore, The inflection point of f(t) is approximately t = 3.73.

The probability that exactly three out of four items are acceptable is approximately 0.4396.

To find the probability that exactly three out of four items are acceptable, we can use the hypergeometric distribution formula.

The hypergeometric distribution is used when sampling without replacement from a finite population. In this case, the population consists of 15 items, 10 of which are acceptable.

The formula for the hypergeometric distribution is:
P(X = k) = (C(A, k) * C(N - A, n - k)) / C(N, n)

Where:
- P(X = k) is the probability of getting exactly k acceptable items in the sample
- C(A, k) represents the number of ways to choose k acceptable items from the population
- C(N - A, n - k) represents the number of ways to choose n - k non-acceptable items from the remaining population
- C(N, n) represents the number of ways to choose n items from the population

Plugging in the values for our question:
- A = 10 (number of acceptable items)
- N - A

= 15 - 10

= 5 (number of non-acceptable items)
- n = 4 (sample size)

We want to find P(X = 3), so k = 3.

Using the formula, we can calculate:
P(X = 3) = (C(10, 3) * C(5, 4 - 3)) / C(15, 4)

C(10, 3) = 10! / (3! * (10 - 3)!)

= 120
C(5, 1) = 5! / (1! * (5 - 1)!)

= 5
C(15, 4) = 15! / (4! * (15 - 4)!)

= 1365

P(X = 3) = (120 * 5) / 1365

= 0.4396 (rounded to 4 decimal places)

Step-by-step explanation:

the slope of the graph is 3 and the y-intercept is -27. This means that the graph crosses the y-axis at the point (0,-27).

Answer:

y = -3x - 27

Step-by-step explanation:

9x - 3y = 81

-3y = 9x + 81

-3y/3 = 9x/3 + 81/3

-y = 3x + 27

y = -3x - 27

\((2x - 9) + (3x - 6) = 110\)

\(2x + 3x - 9 - 6 = 110\)

\(5x - 15 = 110\)

Plus sides 15

\(5x - 15 + 15 = 110 + 15\)

\(5x = 125\)

Divided sides by 5

\( \frac{5}{5}x = \frac{125}{5} \\ \)

\(x = 25\)

Thus ;

A = 2 ( 25 ) - 9°

A = 50° - 9°

A = 41°

_________________________________

B = 3 ( 25 ) - 6

B = 75° - 6°

B = 69°

_________________________________

C + 110° = 180°

because it is a straight line.

Subtract sides 110°

C + 110° - 110° = 180° - 110°

C = 70°

The expression\(10x^5 + 4x^4 + 8x^3\) can be factored completely as \(2x^3(5x^2 + 2x + 4)\).

To factor the expression \(10x^5 + 4x^4 + 8x^3\), we first observe that all terms have a common factor of 2\(x^3\). Factoring out this common factor, we get:

\(10x^5 + 4x^4 + 8x^3 = 2x^3(5x^2 + 2x + 4)\).

Now, let's focus on factoring the quadratic term \(5x^2 + 2x + 4\) further. This quadratic cannot be factored using integer values, so we can apply the quadratic formula or complete the square to find its factors. However, in this case, the quadratic does not appear to have any rational factors.

Therefore, the factored form of the expression \(10x^5 + 4x^4 + 8x^3\) is \(2x^3(5x^2 + 2x + 4)\), where \(5x^2 + 2x + 4\) is the irreducible quadratic term that cannot be factored any further using integer values.
