The diameter of the average cell in the human body is 1 x 10-5 meters. The diameter of a grain of sand is about 2 x 10-4 meters.

The diameter of a human hair is about 0.000025 meters. The smallest known bacteria are from the genus Mycoplasma and can measure as small as 300 nanometers in diameter. Given that 1 meter = 1 x 109 nanometers, what is the diameter of the smallest bacteria, in meters? Give your answer in scientific notation and show your work.

Which is traveling faster, a car whose velocity vector is 201 + 25), or a car whose velocity vector is 30i, assuming that the un
ioda

Answer with explanation:

For any object having the velocity vector as

\overrightarrow{v}=v_x\widehat{i}+v_y\widehat{j}+v_z\widehat{k}

the magnitude of velocity is given by

|v|=\sqrt{v_x^2+v_y^2+v_z^2}

For car 1 the velocity vector is

\overrightarrow{v}_1=20\widehat{i}+25\widehat{j}

Therefore

|v_1|=\sqrt{20^2+25^2}\\\\\therefore v_1=32.0156units

Similarly for car 2 we have

\overrightarrow{v}_2=30\widehat{i}

Therefore

|v_2|=\sqrt{30^2}\\\\\therefore v_2=30.0units

Comparing both the values we find that car 1 has the greater speed.

Anton will be constructing a segment bisector with a compass and straightedge, while Maxim will be constructing an angle bisecto
elena-14-01-66 [18.8K]

A bisector is a line that divides either a line or an angle into <em>two</em><em> proportionate</em> parts or angles. Thus, Anton's <em>bisector</em> would divide the segment into two <u>equal parts</u>, while Maxim's <em>bisector</em> would divide the angle into two <u>equal angles</u>.

The <u>similarities</u> between their construction are:

  • <em>Intersecting</em> arcs through which the bisector would pass are required.
  • The arcs are dawn using <em>the same</em> radius of any measure.
  • The <em>edges</em> of the arc of the given angle, and the ends of the segment are used as <em>centers</em>.

The <u>differences</u> between their construction are:

  • Anton has to draw two intersecting arcs <u>above</u> and <u>below</u> the segment. While Maxim would draw two intersecting arcs <u>within</u> the lines forming the angles.
  • Anton's bisector would be <em>perpendicular</em> to the segment, while Maxim's bisector would be at <em>an angle</em> which is half of the initial angle.

Which is the most accurate way to estimate 26% of 91?
notka56 [123]

Answer:

B

Step-by-step explanation:

26% is close to 25%, which is equal to 1/4th.

You're adding to the number and removing from the percentage so it balances it out.

kipiarov [429]

Answer:

13.

parallel: y = 1/3x -3

perpendicular: y = -3x - 3

14.

parallel: y = 4x - 1/2

perpendicular: y = -1/4x - 1/2

15.

parallel: y = -2x + 4

perpendicular: y= 1/2x + 4

16.

parallel: y = -2x-2

perpendicular: y= 1/2x-2

17.

parallel: y = -2x+8

perpendicular: y= 1/2x + 8

Step-by-step explanation:

A perpendicular has a negative reciprocal slope and a parallel has the same slope
