The quadratic equation whose roots are 3-√3 and 3+√3​

Answers

Answer 1

Answer:

x²-6x +6

Explanation:

in general (x-root1) (x-root2) will give you the equation

for our case, the equation is given by

(x-3+√3)(x-3-√3), distribute

x²-3x-x√3 -3x+9+3√3+x√3-3√3-√9, group like terms and substitute √9 by 3

x²+(-3 -√3 -3 +√3)x +(9 +3√3 -3√3 -3), combine like terms

x²-6x +6

MY COUNTRY

(english)

Such a small country, spread on an isthmus

where the sky is clearer, the sun brighter;

all your music echoes within me, like the sea

in the small cell of the conch.

Yet again, there are times I feel dread

when I don’t see the way back to you…

Perhaps I’d never have known such love,

if destiny hadn’t carried me over the sea.

______________________________________

(Español)

Un país tan pequeño, extendido en un istmo

donde el cielo es más claro, el sol más brillante;

toda tu musica resuena dentro de mi, como el mar

en la pequeña celda del caracol.

Una vez más, hay momentos en los que siento pavor

cuando no veo el camino de regreso a ti ...

Quizás nunca hubiera conocido tal amor

si el destino no me hubiera llevado sobre el mar.

The Escobar family went on a car trip. They drove 100 miles on country roads and 240 miles on the highway. They drove 50% faster on the highway than on the country roads. Let r represent their rate on country roads in miles per hour. a. Write and simplify an expression that represents the number of hours it took the Escobar family to complete their trip in terms of r. (Hint: 50% faster means 150% of the original rate.) b. Find their total travel time if they drove the posted speed limit.

Answer: Hey I'm sorry I didn't get to answer your question it's just that I need the points because I don't have enough to get help with my question. I hope you get the answer that you need for you question. Good Luck :)..

Explanation:

The expression that represents the number of hours it took the Escobar family to complete their trip in terms of r is 260/r

The expression for the total time of travel?

Let r represent their rate on country road and R represent their rate on highway.

So, we have:

R = (100% + 50%) * r

Evaluate

R = 1.5r

Rate is calculated using:

Rate = Distance/Time

So, we have:

r = 100/t and R = 240/T

Make T and t the subject

t = 100/r and T = 240/R

The total time of travel is:

Total = t + T

So, we have:

Total = 100/r + 240/R

Substitute R = 1.5r

Total = 100/r + 240/1.5r

Simplify

Total = 100/r + 160/r

Evaluate the sum

Total = 260/r

The total time of travel

The speed limit is 40mph

This means that:

r = 40

In (a), we have:

Total = 260/r

Substitute 40 for r

Total = 260/40

Evaluate

Total = 6.5

Hence, their total time of travel is 6.5hours
