What is the slope for 1.(4,9) & (1,6)

Semenov [28]

Step-by-step explanation:

1.(4,9) & (1,6)

m=y²-y¹/x²-x¹

m=6-9/1-4

m=-3/-3

m= 1

2.(5,3) & (5,-9)

m=y²-y¹/x²-x¹

m=(-9)-3/5-5

m=-12/0

3.(2,1) & (8,9)

m=y²-y¹/x²-x¹

m=9-1/8-2

m=8/6

m= 4/3

4.(14,-8) & (7,-6)

m=y²-y¹/x²-x¹

m=(-6)-(-8)/7-14

m=2/-7

m= -2/7

5.(4,-3) & (8,-3)

m=y²-y¹/x²-x¹

m=(-3)-(-3)/8-4

m=0/4

m=0

6.(-11,1) & (-2,6)

m=y²-y¹/x²-x¹

m=6-1/(-2)-(-11)

m=5/9

A submarine travels 7 km due East from its base and then turns and travels due North for 12.5

Maksim231197 [3]

Answer:

The submarine is 10.4 km far from its base.

Step-by-step explanation:

Given that:

Distance traveled east = 7km

Distance traveled north = 12.5 km

This is will form a right triangle, where the distance from east to north is hypotenuse.

Here,

a = 7 , b = x and c = 12.5

Using Pythagorean theorem,

$a^2+b^2=c^2\\(7)^2+x^2=(12.5)^2\\49+x^2=156.25\\x^2=156.25-49\\x^2=107.25$

Taking square root on both sides

$\sqrt{x^2}=\sqrt{107.25}\\x=10.4$

Hence,

The submarine is 10.4 km far from its base.
