Find values of x and y for which ABCD must be a parallelogram. The diagram is not drawn to scale.

Arturiano [62]

ANSWER
$x=4, y=8$

EXPLANATION

If ABCD is a parallelogram, then

line AB is parallel to line DC .

This means that,

$(x + 2) \degree$
and

$(2x - 2) \degree$
are alternating angles.

Alternate angles are congruent.

This implies that,

$2x - 2 = x + 2$

We group like terms to obtain,

$2x - x = 2 + 2$

This simplifies to,

$x = 4$

Also, if ABCD is a parallelogram then,

BC is parallel to AD. This means that,

$5y - 8 = y + 24$

We group like terms to get,

$5y - y = 24 + 8$

This simplifies to,

$4y = 32$

We divide both side by 4 to get,

$y = 8$

I need help please.....

Here, Function: h(t)= -16t² + 70t + 40

So, put the value of t, (time at which you want to calculate the height)

h(1) = -16(1)² + 70(1) + 40
h(1) = -16 + 110
h(1) = 94

Now, h(2) = -16(2)² + 70(2) + 40
h(2) = -64 + 180
h(2) = 116

h(3) = -16(3)² + 70(3) + 40
h(3) = -144 + 250
h(3) = 106

In short, Your height depends on time, and at each time it would be different, can be expressed by the coordinates on a Graph: (1, 94) (2, 116) (3, 106)

Hope this helps!

¿Cuál es el volumen de una lata de chícharos que tiene un diámetro de 6 cm<br>y una altura de 8 cm?

ivanzaharov [21]

Answer:

La respuesta podría ser 226.08 o 72π, dependiendo de si quieren que redondees pi o que solo pongas el símbolo.

Step-by-step explanation:

Para hallar el volumen de un cilindro, hay que primero hallar el área del círculo que tiene, por así decirlo. Entonces sería el radio al cuadrado, o sea 3 por 3 porque el diámetro es 6. Y luego lo multiplicamos por pi, y vendría siendo 9π o 9(3.14). Después, lo multiplicamos por la altura, 8 cm. Lo que nos daría 72π, o 226.08 ya redondeado.
