Which units should she use to report the distance from the earth to the moon?
Anvisha [2.4K]
Well,

The distance from the earth to the moon, FYI, is over 200,000 miles.  That is a LONG distance.  We are trying to find a reasonable unit of measurement.

What do we mean by "reasonable?"  We mean that that unit should be able to express the distance as a number that is not huge or tiny.  In other words, we want it to be as close as possible to 1.

mm, or millimeters, is a tiny unit.  It is not reasonable.

cm, or centimeters, is also a tiny unit.  It also is not reasonable.

m, or meters, is also a relatively small unit.  It also is not reasonable.

km, or kilometers, is the largest of the four.  In km, the distance from the earth to the moon is about 363,000 km.  That's not too bad.

However, if these weren't the only options, I would choose Mm, or megameters, which would put the distance at 363 Mm.

The correct option is D.

What is the point-slope form of a line with slope 3 that contains the point (2,1)
ryzh [129]

Answer:

Point slope form:

The equation of line is given by: y-y_1=m(x-x_1)        .....[1]

where m is the slope and a line contains a point (x_1, y_1).

As per the given statement:

Slope(m) = 3

(x_1, y_1). = (2, 1)

Substitute these in [1] we have;

y-1=3(x-2)

therefore, the point slope form of a line with slope 3 that contains the point (2, 1) is; y-1=3(x-2)

One positive number is three more than twice another. If their product is 629, find the numbers.
sineoko [7]

Answer:

x = 17 and y = 37

Step-by-step explanation:

Let the numbers be x and y.

y = 3 + 2x

xy = 629

substituting y in the second equation we get

x(3+2x) = 629

3x + 2x^{2} = 629

2x^{2} + 3x - 629 = 0

Solving a quadratic equation by using its formula:

x = [-3 ±√(9-4(2)(-629)] / 4

x = [-3 ± √5041] / 4

x = [-3 ± 71] / 4

x = 17 and \frac{-37}{2}

Ignore the negative number in x and just use x = 17 in the first equation we get

y = 3 + 2(17) = 37
