What interval consists of all $u$ such that neither $2u$ nor $-20u$ is in the interval $(-\infty,-1)$ ?

Answers

Answer:

[-1/2,1/20]

Step-by-step explanation:

Answer:

[-1/2,1/20]

Step-by-step explanation:

In terms of inequalities, we are asked to find all $u$ such that $2u\ge -1$ and $-20u\ge -1$.

The solution to the first inequality, obtained by dividing both sides by $2$, is $u\ge -\frac{1}{2}$.

We can solve the second inequality by dividing both sides by $-20$, but because we are dividing by a negative number, we must reverse the direction of the inequality: $u\le \frac{1}{20}$.

The set of $u$ which satisfy both inequalities simultaneously is thus $\boxed{\left[-\frac{1}{2},\frac{1}{20}\right]}$.

X-3 and passes

through the point (4, 6)?

Answers

Answer:

y = 1/2x + 4

Step-by-step explanation:

If it's parallel, then the slope will remain the same.

To find the y-intercept, you have to plug the coordinates into the equation.

y = 1/2x + b

6 = 1/2 (4) + b

6 = 2 + b

4 = b

SE TIENE 45 NIÑOS Y 35 NIÑAS. DE LOS CUALES 60 VIVEN EN EL DISTRITO DE BREÑA. SI EL 30% QUE NO VIVEN EN BREÑA SON MUJERES. ¿QUÉ CANTIDAD SON VARONES?

Answers

Answer:

14 son varones

Step-by-step explanation:

Primero tenemos que sumar la cantidad de niños y niñas para saber cuantos hay en total

45 + 35 = 80

60 de ellos viven en el Distrito de Breña entonces los descontamos del total

80 - 60 = 20

Esto nos dice que 20 NO viven en Breña. Si 30% son mujeres quiere decir que el resto 70% son varones. Asi que multiplicamos los 20 por 70% en formato decimal que seria 0.70

20 * 0.70 = 14

Finalmente, podemos ver que 14 son varones viviendo fuera de Breña

Answer: x^2+29x+39

You would first have to set up an equation, which would be ((2x+9)⋅(x+6))-((x-5)⋅(x-3)) to find the area of both rectangles.

Then you can simplify it, which gives us 2x^2+21x+54-(x^2-8x+15)

Then simplify it even more which gives us 2x^2+21x+54-x^2+8x-15

Then we can get our answer: x^2+29x+39

Explicación paso a paso:

La energía potencial gravitacional adquirida se puede obtener mediante la relación:

EPG = masa * aceleración por gravedad * altura

Masa = 52 kgb; aceleración debida a la gravedad = 9,81; h = 8 metros

EPG = 52 * 9,81 * 8

A population of llamas stranded on a desert island is decreasing due to a food shortage by 6% per year. If the population of llamas started out at 350, how many are left on the island 10 years later?

Answers

Answer:

189

Step-by-step explanation:

Given data

Initial population=350

Rate = 6%

TIme= 10 years

Let us apply the compounding expression

A=P(1-r)^t----------The negative sign is due to decreasing value

substitute

A= 350(1-0.06)^10

A=350(0.94)^10

A=350*0.5386

A=188.51

Hence the approximate population will be 189
