A submarine is running at a depth of 235 ft underwater. It changes course and rises 101 ft. What is the change in elevation?
Bumek [7]

Answer:

The change in elevation is -134 ft

Step-by-step explanation:

Given;

initial depth of the submarine, d₁ = 235 ft

final depth of the submarine, d₂ = 101 ft

The change in the elevation of the submarine is given by;

Δd = d₂ - d₁

Δd = 101 ft - 235 ft

Δd = -134 ft

The change in elevation is negative because the submarine is moving closer to the surface.

Therefore, the change in elevation is -134 ft

Viktor [21]

The answers to the questions are:

  • a. $33,750
  • b. $36000
  • c. $90000

a. <u>the straight-line method of depreciation</u>

\frac{cost of machine - salvage}{useful life} * period

= (240000 - 60000) / 4 * (9 / 12)

= $33,750

The debit is 33750 as well as the credit

b. <u> the units-of-production method of depreciation</u>

(240000 - 60000) / 60000 * 12000

= $36000

c. <u>the double-declining balance method of depreciation</u>

(24000 *2 /4) * (9/12)

= $90000

What are the x-intercepts for the quadratics below(show all work in order
NeX [460]

Answer:

Step-by-step explanation:

The x intercepts occur when the quadratic is equal to zero.

1.

x^2-7x-18=0 factoring we get

(x-9)(x+2)=0 since multiplying anything by zero is zero the x intercepts occur when

x=-2 and 9

2.

2b^2+17b+21=0

2b^2+14b+3b+21=0

2b(b+7)+3(b+7)=0

(2b+3)(b+7)=0

b=-7 and -1.5
