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,

$y = 8$

The measurements 45.367 cm and 43.43 cm are made in the same unit of measure. Which measurement is less precise? Explain your an

Kaylis [27]

Answer:

45.367 cm

Step-by-step explanation:

Approximating to a more number of decimal places gives a better estimation of the exact value.

For 45.367 cm, we approximated to three decimal places or five significant figures.

For 43.43 cm, the approximation is done to four decimal places.

Therefore the measurement 45.367cm is more precise because it has a relatively smaller error.

A penny fell off the top of the building and hit the sidewalk below 3.1 seconds later how many meters did the penny fall to the

Sedbober [7]

To solve this we are going to use the free distance fallen formula: $d=0.5gt^2$
where
$d$ is the distance
$g$ is the gravity of Earth $9.8m/s^2$
$t$ is the time in seconds

We know from our problem that the penny fell off the top of the building and hit the sidewalk below 3.1 seconds later, so $t=3.1$ . Lets replace the value in our formula:
$d=0.5gt^2$
$d=0.5(9.8)(3.1)^2$
$d=47.089$ meters

We can conclude that the penny fell a distance of 47.098 meters

How many zeros are in f(x) = 3x^4 + x + 2

lana [24]

Answer:

The power of the polynomial determines the number of zeroes it has in this case power is 4 so 4 zeroes. Whereas in 5^3+4 it has 3 zeroes as its power is 3. U can find the zero by trial and error method.

Hope this helps.
