Which equation has the solutions x = 1 plus-or-minus StartRoot 5 EndRoot?

Sophie [7]

Answer:

The quadratic equation is x^2-2x-4

Step-by-step explanation:

We want to know the equation that has the solution below;

x = 1 ± √5

This means x = 1 + √5 or 1 - √5

The equation would thus be;

(x-1-√5)(x-1+ √5)

= x(x-1+ √5)-1(x-1+ √5)-√5(x-1+ √5)

Opening the brackets we have ;

x^2-x+ √5x-x + 1 -√5-√5x+ √5-5

collecting like terms we have;

x^2-2x+1-5

= x^2-2x-4

Step-by-step explanation:

a.)Buying: total cost

Total cost= commission + (price per share× Number of of shares ) ;

Total cost= 11 + (19.72×30)= $591.6+11= $601.6

b.)Net gain or loss;

First, find cash received from sale of stock and deduct commission;

Cash from sale =20.75×30= $ 622.5

deduct commission= 622.5-11= $611.5

Gain or loss= sale-cost = 611.5-601.6 = $9.9, meaning there is a profit.

c.) Annual rate of return= (net gain or loss/amount paid)×100%

return= 9.9/(601.6)×100 = 1.645%

A student is training for the swim team during July and August one summer. She swims one hour every day, while averaging 800 met

Alex787 [66]

Step-by-step explanation:

Please find the attachment.

Let x be the number of hours the student swims per day.

We have been that a student swims one hour every day, so in 2 months the student will swim 60 hours.

We are also told that the student swims 800 meters each day. This means that slope of the graph that represents the total meters swam during the time of her training program will be 800.

So in 60 days the student will swim $60\times 800=48,000\text{ meters}$ .

We can see from our attached graph that at x equals 60 our y is approximately 48.

Since y-axis represents the number of meters in thousands, so 48 stands for 48,000.

Therefore, attached graph is the right choice.

How to find the area of a square ABC D

____ [38]

Answer:

The answer to your question is 13 u²

Step-by-step explanation:

We know that the small triangle is surrounded by right triangles so we can use the Pythagorean theorem to find the lengths of the small triangle

AD² = 3² + 2²

Simplify

AD² = 9 + 4

AD² = 13

AD = $\sqrt{13}$

Find the area of the square

Area = side x side

Area = AD x AD

Area = $\sqrt{13} x \sqrt{13}$

Area = 13 u²
