Find the area of a circle with a radius of 9.6 meters use 3.14 for π Round your answer to the nearest hundredth​

Answers

Answer:

289.38 m^2

Step-by-step explanation:

(9.6)^2 x 3.14 = 289.38 m^2

The area of the circle is [tex]289.38\ m^2[/tex]

Calculation of the ara of the circle:

Since the  radius of 9.6 meters and we use 3.14 for π

We know that

The area of the circle is

[tex]= \pi r^2\\\\= 3.14\times (9.6)^2\\\\= 289.38\ m^2[/tex]

We simply applied the given formula so that the area of the circle could come

Therefore we can conclude that The area of the circle is [tex]289.38\ m^2[/tex]

Andre and Elena are each saving money. Andre starts with $100 in his savings account and adds $5 per week. Elena starts with $10 in her savings account and adds $20 each week.

Answers

Answer:

6 weeks

Step-by-step explanation:

You need to write an equation for each.

For Andre, he has 100 dollars, and every week gets 5 dollars more. You add the 5 dollars, and Since you don't know how many weeks it has been, use a variable.

For Elena, she has 10 dollars, and gets 20 each week.

Now that you know that it has been 4 weeks, you can plug in 4 for the variable for weeks.

Andrew:100+5(4)=100+20+120

Elena: 10+20(4)=10+80=90

Andrew has more money in this time.

To find when they have the same amount, equal their expressions to each other. This means that they will have the same amount (because they are equalled) and you can solve to find the variable, which means the weeks that they are equal at.

Bring the like terms to each side by canceling them out. Since you have positive 10, then subtract 10 to each side. You have 5w, so subtract 5w to each side.

100+5w=10+20w

90+5w=20w

90=15w

90 divided by 15=6

w=6

Carlos debe estudiar para seis evaluaciones para ello distribuirá entre las seis materias 1/4 del tiempo del que dispone este fin de semana

Answers

Answer:

[tex]Tiempo = \frac{1}{24}[/tex]

Step-by-step explanation:

La pregunta está incompleta, sin embargo, una posible pregunta podría ser calcular el tiempo que Carlos dedicará a estudiar cada asignaturas.

Para hacer esto, simplemente dividimos el tiempo disponible por el número de asignaturas.

Tenemos:

[tex]Tiempo\ disponible = \frac{1}{4}[/tex]

[tex]Numero\ de\ sujetos = 6[/tex]

Solución

[tex]Tiempo = \frac{Tiempo\ disponible}{Numero\ de\ asignaturas}[/tex]

[tex]Tiempo = \frac{1}{4} / 6[/tex]

[tex]Tiempo = \frac{1}{4} * \frac{1}{6}[/tex]

[tex]Tiempo = \frac{1}{24}[/tex]

EXPLAIN when |−x| = x would be true.
HINT: If you are stuck, try substituting each of x = -1, x = 0, and x = 1 into the equation. Then, interpret your results.

Answers

Answer:

It's true when x = a positive number.

Step-by-step explanation:

I don't know how to explain this, so here we go.

The definition of absolute value is the distance a number is away from 0.

In other words, all numbers are now positive or 0.

If |-x| = x, it means x would have to be positive because, well, to prove that, we have to see what it couldn't be a negative number

if x was a negative number (-1), this is what we would get

|-(-1)| = -1

|1| = -1

1 = -1

That's not right!

And this happens in any negative number you do.

Because the absolute value of something cannot be negative

I cannot stress that enough

Since it is the absolute value of -x, x has to be positive, if it isn't, then there is no solution for x.

Any number greater than or equal to zero is a possible answer for the absolute value of something, but the absolute value of something cannot be a negative number

I hope this helps, let me know if you have any questions.

You use it when dealing with absolute value. Those lines around the x represent absolute value. AV essentially means that whatever is in the lines equals that number, but positive. AV by definition means the distance from 0.

So, 7 and -7 are both 7 (absolute value) from 0.

Hope that helps!

Step-by-step explanation:

1.) the first thing we do is expand the exponent (or mulitply  (x-2)(x-2) the images below will show you how to do that

We get x²-4x+4 and then just need to add three

x²-4x+7

2.)

We do the same thing (expand the exponent) and get x²+6x+9

which means so far we have

-(x²+6x+9)-3

carry out the negative sign and subtract 3
