Tatiana is practicing shooting. The coordinates (in m) of the barrel of her gun and the target are (5, 3, 1) and (38, 41, 3). Wh

saul85 [17]

Answer:

$d=\sqrt{2,537}\ m$ or $d=50.37\ m$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points in three dimensions is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}+(z2-z1)^{2}}$

Let

$A(5,3,1)$ -----> coordinates of the barrel of her gun

$B(38,41,3)$ -----> coordinates of the target

substitute the values

$d=\sqrt{(41-3)^{2}+(38-5)^{2}+(3-1)^{2}}$

$d=\sqrt{(38)^{2}+(33)^{2}+(2)^{2}}$

$d=\sqrt{1,444+1,089+4}$

$d=\sqrt{2,537}\ m$

$d=50.37\ m$

Look at the figures. How can you prove these triangles are congruent?

Novosadov [1.4K]

Answer:

A. $\Delta ABC\cong \Delta DEF$ by the SAS postulate.

Step-by-step explanation:

We have been two triangles. We are asked to determine the theorem by which both triangles could be proven congruent.

We can see that side DF of triangle DEF is equal to side AC of triangle ABC.

We can also see that side BC of triangle ABC is equal to side EF of triangle DEF.

The including angle between sides AC and BC of triangle ABC is equal to the including angle between sides DF and EF of triangle DEF.

Since both triangles have two sides and their included angles equal, therefore, triangle ABC is congruent to triangle DEF by SAS (Side-Angle-Side) congruence and option A is the correct choice.

Compare the values of the underlined digits 6,300 and 530 with three being the underlined digit.

NNADVOKAT [17]

In Comparing 2 underlined numbers which is 3, we need to find its place value In order to be able to find the difference of each given numbers.

First is 6300 => 6000 + 300 or may also say as 6 thousands + 3 hundreds
therefore the value of underlined number is hundreds

next, 530 => 500 + 30 or may also say as 5 hundreds + 3 tens.
Therefore, the value of underlined number tens.

Thus, the difference between the 2 underlined numbers is, the first given digit falls at hundreds place and the second is in tens place.
