Answer:

<em>Explicación más abajo</em>

Step-by-step explanation:

Integración Indefinida

La integral

I=\int \dfrac{x .arcsen\left(x\right)}{\sqrt{1-x^2}}

Se resuelve con el cambio de variables:

t=arcsen(x)

Una vez hechos los cambios, la integral se resuelve en función de t:

I=sen(t)-t.cos(t)+C

Hay que devolver los cambios para mostrarla en función de x.

El cambio de variables también se puede escribir:

x=sen(t)

Recordando que

cos(t)=\sqrt{1-sen^2(t)}

Entonces:

cos(t)=\sqrt{1-x^2}

Devolviendo los cambios:

I=sen(t)-t.cos(t)+C=x-arcsen(x)\sqrt{1-x^2}+C

Es la respuesta correcta

Helen [10]

Answer: 6 1/5 miles

Step-by-step explanation:

Here's the complete question:

On Tuesday, Stacy rode her bicycle 1 3/4 miles from her house to the supermarket. She walked 1/4 of a mile while at the supermarket. She rode her bicycle a different way home that was 2 1/5 miles long. How many miles did Stacy ride her bicycle on Tuesday.

The number of miles that Stacy ride her bicycle on Tuesday will be the addition of her distance from her house to the supermarket and back to her house from the supermarket. This will be:

= Distance to supermarket = 1¾ + ¼ = 2 miles

Distance from supermarket = 2 + 2 1/5 = 4 1/5 miles

Total distance = 2 + 4 1/5 = 6 1/5 miles

Answer:

The difference in area between the trapezoid and the rectangle is 10 in²

Step-by-step explanation:

The dimensions of the trapezoid are given as follows;

Base 1, a = 12 in

Base 2, b = 10 in

Height, h = 10 in

Area, A of trapezoid;

A = \frac{a+b}{2} h = \frac{10+12}{2} 10 = 110 in^2

The dimensions of the rectangle are given as follows;

Base = 12 in

Height = 10 in

Area, A of rectangle;

Base × Height = 12 × 10 = 120 in^2

Therefore, the difference in area between the two packages is found as follows;

Difference in area between trapezoid and rectangle = 120 - 110 = 10 in²

The difference in area between the trapezoid and the rectangle = 10 in².
