Y = kx

k =y/x
k = 6/ 2/3
k = 9

12 = 9x

x = 12/9 = 4/3

ou are standing 45 meters from the base of the Empire State Building. You estimate that the angle of elevation to the top of the

svetlana [45]

Answer:

443.2m

Step-by-step explanation:

Given in the question that,

distance from building to me = 45m

angle of elevation = 82°

building is 123 m + x m high

If we closely observe then this situation make a right angle triangle and we will use trigonometry identity to solve the question.

Step 1

tan(82) = y / 45

y = 45tan(82)

y = 320.2 m

Step 2

Hence the height of building is y + 123m. So, plug the value of y in this

320.2 + 123 = 443.2

Enter an equation in point-slope form for the perpendicular bisector of the segment with endpoints (−3, 7) and (1, −5).

Gelneren [198K]

First find the slope of the line segment joining the points.
Slope = ((-5)-7)/(1-(-3)) = -3

The slope of any perpendicular to the line is 1/3

Find the midpoint of the line segment by taking the average of the coordinates.
x-coord of midpoint = (-3+1)/2 = -1
y-coord of midpoint = (7-5)/2 = 1
Midpoint : (-1,1)

Point-slope equation for line of slope 1/3 that passes through (-1,1):
y-1 = (1/3)(x+1)

Johnson's Nursery has net income of $42,500, depreciation expense of $1,800, interest expense of $900, taxes of $1,600, addition

Anuta_ua [19.1K]

Answer:

free cash flow is $31167.35

Step-by-step explanation:

given data

net income = $42,500

depreciation expense = $1,800

interest expense = $900

taxes = $1,600

net working capital = $2,300

to find out

What is the amount of the free cash flow

solution

we know that FCF free cash flow formula that is

FCF = Net income + depreciation - net working capital - capital expenditures + interest expense × ( 1 - tax rate) ........................1

here tax rate is calculate as

tax rate = tax paid ÷ (net income + taxes paid)

so here from equation 1 we get FCF

free cash flow =42,500 + 1,800 - 2,300 - 11,700 + 900 × (1 - $\frac{1600}{1600+42500}$ )

free cash flow = 31167.35

so free cash flow is $31167.35
