A student finds the slop of the line between (4, 3) and (-2, -2). She writes -2–4/-2–3. What mistake did she make?

Her mistake is that she did the change in x over the change in y. It should be the change in y over the change in x. So: -2-3/-2-4

In the slope formula, The difference in the y-values are on the numerator and the difference in the x-values are on the denominator.
It should be:
(-2-3)/(-2-4)

The client drank 6 ounces of orange juice and 4 ounces of coffee for breakfast, 8 ounces of tea and 6 ounces of ginger ale for l

algol13

Answer:

946.242 milliliters

Step-by-step explanation:

The client drank 6 ounces of orange juice and 4 ounces of coffee for breakfast. We need to convert ounces to milliliters

1 ounce = 29.574 milliliters

6 ounces of orange juice

= 6 × 29.574 = 177.444 milliliters

4 ounces of coffee = 4 × 29.574 = 118.296 milliliters

For lunch, he consumed 8 ounces of tea and 6 ounces of ginger ale.

8 ounces of tea = 8 × 29.574 =236.529 milliliters

6 ounces of ginger ale = 6 × 29.574 =177.444 milliliters

4 ounces of water at 10:00 a.m. and at 2:00 p.m. this means 8 ounces of water.

8 ounces of water = 8 × 29.574 =236.529 milliliters

Total consumption by the client =

177.444 + 118.296 + 236.529 + 236.529= 946.242 milliliters

Haya la integral de xarcsenx/((1-x^2)^1/2). Utiliza la sustitución de t= arcsenx

ikadub [295]

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

Help pleas Describe the power function f(x)=x^5. What does it look like? Where does it cross the x- and y-axis? How many turns d

dezoksy [38]

Answer:53=125

Step-by-step explanation:For an increasing function like this, the end behavior at the right "end" is going to infinity. Written like: as x→∞,y→∞ . That means that large powers of 5 will continue to grow larger and head toward infinity. For example, 53=125 .
