given that n is an integer greater than 1, explain why the largest prime factor of 2(7^n) - 2(7^(n-1)) + 7^(n+1) is 61.

Answers

Answer 1

When we put the value of 1 in place of n in the equation, the value obtained will be equal to the largest prime factor that is 61.

What is a Prime number?

A prime number is any whole number that is greater than 1 and cannot be created by combining other whole numbers. Consequently, a prime number's only factors are 1 and the actual number.

As per the given expression in the question,

2(7ⁿ) - 2(7ⁿ⁻¹) + 7ⁿ⁺¹

Use exponent rule:

[tex]a^b.a^c=a^b^+^c[/tex]

Put the values accordingly,

2(7ⁿ) - 2(7ⁿ⁻¹) + 7ⁿ . 7¹

So,

[tex]\frac{a^b}{a^c}= a^b^-^c[/tex]

⇒ 2(7ⁿ) - 2(7ⁿ/7¹) +  7ⁿ . 7¹

Simplify the above equation,

2(7ⁿ) - 2/7(7ⁿ) + (7)7ⁿ

Take out 7ⁿ as common,

(2 - 2/7 + 7)7ⁿ

Therefore,

61/7(7ⁿ)

Put n = 1 to check for the largest prime number,

61/7(7¹)

= 61

Solve the system of linear equations by substitution.

Answers

[tex] \large{\red{\underline{\bf{Required \: Solution \: : }}}} [/tex]

Here we have been provided with two equations and we have to solve them by substitution method and get the value of x and y.

y = x - 4 (Equation No 1)y = 4x - 10 (Equation No 2)

Here we have been already provided a temporary value of y in first equation so let us substitute in the second equation.

[tex]: \implies \: \sf{y \: = \: 4x \: - \: 10}[/tex]

[tex]: \implies \: \sf{x \: - \: 4 \: = \: 4x \: - \: 10}[/tex]

[tex]: \implies \: \sf{x \: = \: 4x \: - \: 10 \: + \: 4}[/tex]

[tex]: \implies \: \sf{x \: = \: 4x \: - 6}[/tex]

[tex]: \implies \: \sf{x \: - 4x \: = \: - 6}[/tex]

[tex]: \implies \: \sf{ - 3x \: = \: - 6}[/tex]

[tex]: \implies \: \sf{ \cancel - \: 3x \: = \: \cancel- \: 6}[/tex]

[tex]: \implies \: \sf{ 3x \: = \: 6}[/tex]

[tex]: \implies \: \sf{ x \: = \: \dfrac{6}{3} }[/tex]

[tex]: \implies \: \sf{ x \: = \: \cancel\dfrac{6}{3} }[/tex]

[tex]: \implies \: \boxed{\bf{ x \: = \:2 }} \pink\bigstar[/tex]

Therefore, value of x is 2..!!

Finding out value of y :

Here we would substitute the value of x which we got as 2 in the first equation inorder to get the value of y.

[tex]: \implies \: \sf{ y \: = \: x \: - \: 4 }[/tex]

[tex]: \implies \: \sf{ y \: = \: 2 \: - \: 4 }[/tex]

[tex]: \implies \: \boxed{\bf{ y \: = \:-2 }} \pink\bigstar[/tex]

Therefore, value of y is -2.

Cheryl painted her living room walls with two different colors. She painted part of the room yellow and another part green. If the surface area of the walls in her room is 720 ft2 and she painted 288 ft2 yellow, what percent of the room did she paint green?

Answers

Answer:

Total percent of the room did she paint green = 60%

Step-by-step explanation:

Given - Cheryl painted her living room walls with two different colors. She painted part of the room yellow and another part green. If the surface area of the walls in her room is 720 ft² and she painted 288 ft² yellow.

To find - What percent of the room did she paint green ?

Proof -

Given that,

The surface area of the walls in her room = 720 ft²

Total area painted in yellow color = 288 ft²

So,

Total area painted in green color would be = 720 - 288 = 432 ft²

Now,

Let the total percent green color painted = x

So,

720 × x% = 432

⇒[tex]720*\frac{x}{100} = 432[/tex]

⇒ x = [tex]\frac{432*100}{720}[/tex] = 60

∴ we get

Total percent of the room did she paint green = 60%

A plane traveled 1092 miles to Riyadh and back. The trip there was with the wind. It took 6
hours. The trip back was into the wind. The trip back took 7 hours. Find the speed of the plane
in still air and the speed of the wind.

Answers

Answer:

Step-by-step explanation:

p and s was are the speeds of the plane and wind, respectively.

Traveling with the wind, the plane moves p+w miles per hour.

p+w = (1092 miles)/(6 hours) = (182 miles)/hour

Traveling against the wind, the plane moves p-w miles per hour.

p-w = (1092 miles)/(7 hours) = (156 miles)/hour

Add the equations together

p+w = 182

p-w = 156

—————-

2p = 338

p = 169 miles per hour

w = p-156 = 13 miles per hour

Valentina's family is planning to have a party for her quinceanera. They are considering two different locations to rent for her party. Casa Lucia charges a $200 one-time rental fee plus $500 per hour. The Silver Fox charges $200 per hour plus a $1,100 one-time rental fee. Explain what the solution to the system of equations represents in this real-world context.

Answers

Answer:

number of hours = 3 hours

Step-by-step explanation:

Let

x = number of hours

Casa Lucia = 200 + 500x

Silver Fox = 1,100 + 200x

To solve the equation, equate both cost of rent

Casa Lucia = Silver Fox

200 + 500x = 1,100 + 200x

200 - 1,100 = 200x - 500x

-900 = - 300x

x = -900 / -300

x = 3 hours

number of hours = 3 hours

The solution to the system of equations in this real-world context represents the number of hours both locations can be rented with the same cost.

It means both locations cost the same if rented for 3 hours each

Perform the indicated multiplication (squaring of x + 1):
