avanturin [10]

Answer:

$New\ Position = -415m$

Step-by-step explanation:

Given

$Position= -300m$

$Descend = 115m$

Required

Determine the new position

It descends means that it moved in the downward position.

So, the new position is:

$New\ Position = Position - Descend$

$New\ Position = -300m - 115m$

$New\ Position = -415m$

<em>Hence, the new position f the submarin is -415m</em>

Find the center, vertices, and foci of the ellipse with equation x squared divided by 400 plus y squared divided by 625 = 1

Inessa05 [86]

Answer:

x^2/400 + x^2/625

(x-0)^2/400) +(y-0^2/625)

x^2=400

X=sqrt. 400

x = 20

y^2=625

y = sqrt. 625

y= 25

a^2-c^2=b^2

sqrt 400-625 = c

20-25=c

The correct answer is c=-5
