Here,
The velocity v that an object r units from Earth's center must have in order to escape Earth's gravity is given by,
We have to find, Earth's gravity for the object's mass M.
What is Velocity?
The distance covered by a body in a unit time in a particular direction is called velocity.
Now,
Earth's gravity is given by,
In terms of mass M,
⇒ .
So, Earth's gravity for the object's mass M is .

Answer:
Perimeter = 14 + 2sqrt(17)
Area =28
Step-by-step explanation:
FG = 8 counted
EH = 6 counted
using the pythagorean theorem
height = 4 and the base = 1 in the right triangle
HG^2 = 4^2 + 1 ^2
hg^2 = 16+1
hg^2= 17
hg= sqrt(17)
ef^2 = 4^2 + 1 ^2
ef^2 = 16+1
ef^2= 17
ef=sqrt(17)
Perimeter = EF+FG + GH+HE
sqrt(17)+ 8+ sqrt(17) + 6
14 + 2sqrt(17)
A =1/2 (b1+b2) * h
b1 =EH b2 = FG and h = 4 height that we used in the perimeter
= 1/2 (6+8) * 4
= 1/2 * 14*4
=28

Answer:
-110 feet
Step-by-step explanation:
the elevation of the sea floor relative to sea level can be found by muktiplying the divers elevation by the given factor
to calculage the elevation of the sea floor, we first need to find the elebation of the diber relativeto sea level. Given that the diver's elevation is -40 feet, we can use this as our starting point.
to find the elevation of the sea floor level, we multiply the divers elevation ny 1 3/4. Let's convert 2 3/4 to make an improper fraction to make the calculation easier
2 3/4 is equivalent to (2*4+3) / 4= 11
-40* 11/4 = 440/4 = -110 feet.
therefore the elevation of the sea level is -110 feet

An inequality is solved the same way an equation is solved, with one exception. If an operation is performed that changes ordering, then the comparison symbol is reversed. The usual case is multiplication or division by a negative number:
2 > 1
-2 < -1 . . . . both sides multiplied by -1

Cos (known angle) = adjacent leg / hypotenuse ( distance wanted)
cos(50) = 14 / x
x = 14 / cos50
x = 21.78 feet
The problem doesn't say if the answer should be rounded or not. You may have to round the answer if needed.
You are given the "side" opposite the angle. souse the SOH part Sine=opposite/hypotenuse
so when you plug in the information you get this equation:
sin(50)=14/x
divide both sides by sin(50) and you should get
a hypotenuse of approx. 18.3
A) QR = 8
B) QR = -9
C) QR = 9
D) QR = 18
Answers
Answer: choice D) 18
Explanation:
M is the midpoint of QR, so QM = MR, meaning that the two smaller pieces are equal (the two pieces combine back to QR)
Use substitution and isolate x
QM = MR
2x+5 = 5x-1
2x-5x = -1-5
-3x = -6
x = -6/(-3)
x = 2
If x = 2, then QM is
QM = 2x+5 = 2*2+5 = 9
and MR is
MR = 5x-1 = 5*2-1 = 9
both are 9 units long. Both are the same length as expected, so this helps confirm the answer.
The last thing we do is add up the two pieces QM and MR to get the length of QR. This is using the segment addition postulate.
QR = QM + MR
QR = 9 + 9
QR = 18
note: a negative length is never possible in any situation, so you can immediately eliminate choice B from the list of possible answers without even doing any math.
