New depth = Original depth + additional depth
= - 35.25 + (- 8.5)
= - 35.25 - 8.5
= - 43.75
Hence, new depth of the submarine is - 43.75 meters.
Hello!

Use PEMDAS (order of operations) to solve:
-4 · [3 + (-5)²] ÷ 7
Square -5:
-4 · [3 + 25] ÷ 7
Add the numbers inside of the parenthesis:
-4 · [28] ÷ 7
Multiply -4 and 28:
-112 ÷ 7
Divide:
= -16.
Answer:
Step-by-step explanation:
In this system we have the force of the spring and the gravitational force. The equation that describes that is

where y0 is the equilibrium position when the string is free and y0+y is the new equilibrium position when the object is hanged of the string. By replacing by derivatives we have

the solution for this differential equation is (by using the characterisic polynomial)

hope this helps!!
Answer: =(x - 1) x (x^2 + x + 1)
