Answer:

A = 3 units^2

Step-by-step explanation:

The area of a triangle is

A  = 1/2 bh where b is the length of the base and h is the height

b = the distance from B to C = 4 units = 2  ( watch the scale)

h = the distance from A to C along the x axis =6 units = 3  (watch the scale)

A = 1/2 (2)(3)

A = 3 units^2

Sedaia [141]

Answer:

There are 6 ways to run 10 m between two cones of the four cones giving a maximum available distance to run as 60 meters

Step-by-step explanation:

The parameters given are

Distance between two cones = 10 m

Number of cones = 4

Therefore, number of ways to choose two 10 m distances (distance between two cones) from the four cones = \binom{4}{2} = 6

Hence there are only six 10 m distances to run between two cones which gives a maximum distance available to run as 60 m.

DH = HF      

x + 1 = 3y         

y = (x + 1) ⁄ 3        


GH = HE

 3x – 4 = 5y + 1 

 y = (3x – 5) ⁄ 5 

            

 y = y 

 (x + 1) ⁄ 3 = (3x – 5) ⁄ 5 

5x + 5 = 9x – 15 

4x = 20 

 x = 5 


y = (x + 1) ⁄ 3        

y = (5 + 1) ⁄ 3       

y = 2

Sung Lee invests $4,000 at age 18. He hopes the investment will be worth $16,000 when he turns 25. If the interest compounds con
irinina [24]

Answer:

The growth rate he needs to achieve his goal is approximatelly 19.8%

Step-by-step explanation:

Since the sum will be compounded continuously we have to use the appropriate formula given below:

M = C*e^(r*t)

Where "M" is the final amount, C is the initial amount, r is the interest rate and t is the time elapsed. Since Sung Lee will invest that sum at 18 years old and he wants to recieve the return at 25, then the time elapsed is given by 25 -18 = 7 years. We can now apply the data to the formula:

16000 = 4000*e^(r*7)

4000*e^(7*r) = 16000

e^(7*r) = 16000/4000 = 4

ln[e^(7*r)] = ln(4)

7*r = ln(4)

r = ln(4)/7 = 0.198

The rate of interest is given by (r)*100%, so we have (0.198)*100% = 19.8%.
