Answer:

A: 0

Step-by-step explanation:

Important to remember - total displacement is the direct distance between the start and finish points, and isn't always equal to the total distance travelled.

In the case of the table above, the hiker travels the same distance in opposite directions, which actually means they cancel each other out! Traveling 4 km to the west, then 4 km to east means you end up in the same spot, right? So your total displacement is 0! (or 4 - 4, which equals 0). Same happens with the north-south hikes - the hiker ends up in the same spot, as the displacement is equal to 6 - 6 = 0.

So, the total displacement of the hiker is 0. (Even though the hiker travelled 20 km!)

Answer:

See explanation

Step-by-step explanation:

A. There are 8 points: A, B, C, D, E, F, G and H

B. There are 9 lines in the figure: AB, BC, AC, DE, DF, EF, BE, AD and CF

C. There are 5 planes in the figure: ABC, DEF, ABED, ACFD and BEFC

D. Three points are collinear if they lie on the same line. Collinear points are D,G and F or C,H and F

E. Coplanar points are those which lie in the same plane. Coplanar points are B, E, F and C or A, C, F and D or A, B, E and D or other combinations of four points lying in the same plane

I. Planes ABC and ABE intersect by a line AB

G. Planes BCH and DEF intersect by a line EF

H. Lines AD and DF intersect at a point D

Another way to check the sum of 104+34+228+877

vekshin1

We are asked to identify an another way to solve the given problem or this summation 104 + 34 + 228 + 887. We can verify it by doing of performing the summation in a reverse sequence such 877 comes first, then followed by 228, then followed by 34 and lastly added by 104. Therefore, the answer is 877 + 228 + 34 + 104.This is an another way to solve the given problem.

Write the expression below as a single logarithm in simplest form. logo 7 – log, 7

Svet_ta [14]

Given:

The given expression is:

$\log_b7-\log_b7$

To find:

The single logarithm expression for the given expression.

Solution:

Quotient property of logarithm:

$\log_bm-\log_bn=\log_b\left(\dfrac{m}{n}\right)$

We have,

$\log_b7-\log_b7$

Using quotient property of logarithm, we get

$\log_b7-\log_b7=\log_b\left(\dfrac{7}{7}\right)$

$\log_b7-\log_b7=\log_b\left(1\right)$

Therefore, the required expression is $\log_b\left(1\right)$ .

there are 6 elementary schools in district. each school has 412 students. how many students in all are in the district? Solve th

kiruha [24]

Answer:

2472 students

Step-by-step explanation:

What we know:

- There are 6 schools

- Each school has 412 students

What we're trying to solve:

How many students are there altogether?

To find this, we multiply 412 by 6. Doing this is essentially the same as adding 412 to itself 6 times for each school there is in the district.

412 students × 6 schools

= 2472 students

Therefore, there are 2472 students in the district.

I hope this helps!
