Step-by-step explanation:

An open line is < and >

A filled line is > and equal, and < and equal

when you plug -3.5 into -6 you get 21 but when you go right, ex -3x-6 you get 18 which is less than 21

PLEASE SUPER URGENT!! 14 PTS PLEASE

Answer: h(x) = -1200x^2 + 1950x + 4950

=======================================

Work Shown:

f(x) = revenue from the north

f(x) = -750x^2 + 1500x + 2250

g(x) = revenue from the south

g(x) = -450x^2 + 450x + 2700

h(x) = total revenue, ie add the two revenues

h(x) = f(x) + g(x)

h(x) = (-750x^2+1500x+2250)+(-450x^2+450x+2700)

h(x) = -1200x^2 + 1950x + 4950

Find the values of the trigonometric functions of θ from the information given.

OLga [1]

Answer:

sin(θ) = -(4√15)/17
cos(θ) = 7/17 . . . . . . . given
tan(θ) = -(4√15)/7
csc(θ) = -(17√15)/60
sec(θ) = 17/7
cot(θ) = -(7√15)/60

Step-by-step explanation:

The relationship between sine and cosine is ...

sin² + cos² = 1

Solving for sine gives ...

sin = ±√(1 -cos²)

In this problem, we want the negative root.

sin(θ) = -√(1 -(7/17)²) = -√(240/289) = -(4√15)/17

tan(θ) = sin(θ)/cos(θ) = ((-4√15)/17)/(7/17) = -(4√15)/7

___

And the inverse functions are ...

sec(θ) = 1/cos(θ) = 17/7

csc(θ) = 1/sin(θ) = -17/(4√15) = -(17√15)/60

cot(θ) = 1/tan(θ) = -(7√15)/60

_____

Of course, you're aware that 1/√15 = (√15)/15.

Your firm is contemplating the purchase of a new $570,000 computer-based order entry system. The system will be depreciated stra

Galina-37 [17]

Answer:

IRR = 31.93%

Step-by-step explanation:

Depreciation = 570,000/5 = 114,000

Calculation of Operating cash flow

Operating income = 270000 - 114000 = 156,000

Tax = 156,000 * 35% = 54,600

Operating cash flow = Operating income + Depreciation - Tax = 156,000 + 114,000 - 54,600 = 215,400

Calculation of initial investment

CF0 = Initial investment - Working capital = 570,000 - 73,000 = 497,000

Calculation of the last year cash flow

CF5 = OCF + After tax salvage - Net working capital = 215,400 + 37,000 - 73,000 = 180,100

Calculation of IRR

IRR for the project = IRR(Cashflow from year0, 1, 2,3,4,5) "as attached below picture below"

IRR for the project = 31.93%
