Answer:

To determine the effect of obliques forces from the third dimension on the navigation.

Step-by-step explanation:

When a airplane, balloon, or helicopter flies in air, it is not affected by the planar horizontal and vertical force only. Majorly four forces acts on a  plain namely - weight, lift, drag and thrust. It is easy to understand the affect of forces like weight, lift, drag in 2-dimensional space frame but in order to understand the impact of thrust 3-dimensional space frame is required.

Therefore to navigate safely understanding of 3 dimensions  is necessary.

Cause the world around is is three dimensional the air, ground etc.
if it was two dimensional the airplane would only navigate vertically and horizontally and never be able to go up and down.

What is the measure, in degrees, of the acute angle formed by the hour hand and the minute hand of a 12-hour clock at 6:48
KiRa [710]

Answer:

We know that at 6:00 they are 180 degrees from each other. Every minute, the hour hand moves 1/2 of a degree, and the minute hand moves 6 degrees. So in 48 minutes, the hour hand moves 24 degrees and the minute hand moves 288 degrees. 288-180-24=84. So, 84 degrees.

Solve for c: c=5 5/6 x 2
Marina86 [1]

Hi there!

c=11 2/3

<u><em>1.Convert 5 5/6 into mixed number:</em></u>

<u><em /></u>5 \frac{5}{6}=\frac{35}{6}<u><em /></u>

<u><em>2.Convert 2 into fraction term:</em></u>

<u><em /></u>2=\frac{2}{1}<u><em /></u>

<u><em>3.Convert both fraction into same denominator:</em></u>

<u><em /></u>\frac{35}{6}=\frac{35}{6}<u><em /></u>

<u><em /></u>\frac{2}{1}=\frac{12}{6}<u><em /></u>

<u><em>4.Multiply the two terms:</em></u>

<u><em /></u>\frac{35}{6}<u><em>·</em></u>\frac{12}{6}=\frac{70}{6}<u><em /></u>

<u><em>5.Simplfly the fraction term:</em></u>

<u><em /></u>\frac{70}{6}=\frac{35}{3}<u><em /></u>

<u><em /></u>\frac{35}{3}=11 \frac{2}{3}<u><em /></u>

Therefore, c=11 2/3.

<u><em /></u>

Which value must be added to the expression x^2-3x to make it a perfect-square trinomial?
dalvyx [7]

Answer:

You must add 9/4 in order to make this a perfect square.

Step-by-step explanation:

To make any binomial into a perfect square trinomial, you have to take the middle term (-3), cut it in half (-3/2) and then square it (9/4). This will give you the constant to make a perfect square trinomial every time.

if you subtract the least integer from the greatest integer and divide the difference by 3 the quotient is 5
vodomira [7]
Let a and b be integers and b>a, then we can say:

(b-a)/3=5  now multiply both sides by 3

b-a=15

b=15+a

So there are infinitely many pairs of integers that satisfy the conditions given in the problem. For any value a, b will be 15 units greater.
