The middle point of BC is (0,2), the midpoint of CD is (1,0)
to prove two lines are parallel, prove their slopes are the same.
slope of BD: m=rise/run=4/-2=-2 (the run is negative because to get to B from D on the grid, you have to move from right to left, then upward. If the horizontal move is from left to right, the run is positive)
slope of EG: m=rise/run=2/-1=-2
EG and BD have the same slope, so they are parallel.

The sun is about 93 x 10^6 miles from earth. what is this distance written as a whole number?

agasfer [191]

For this case we have the number in exponential notation:

$93 * 10 ^ 6$

We observe that the exponent of the exponential notation is positive.

Therefore, to express the number as a whole number, we must move the comma 6 spaces to the right.

We have then:

$93 * 10 ^ 6 = 93,000,000$

Answer:

this distance written as a whole number is:

$93 * 10 ^ 6 = 93,000,000$ miles

What is the value of the geometric sequence for which a1=10 and r=0.5?

tiny-mole [99]

The formula for an infinite geometric sequence is the following:

$S_{∞}= \frac{a_{1}}{1-r}$

Just substitute the values of $a_{1}$ and r into the formula.

$S_{∞}=\frac{10}{1-0.5}$
$S_{∞}=\frac{10}{0.5}$
$S_{∞}= 20$

Therefore, the answer is 20.
