The following table shows the expressions that represent the sales of 4 companies:
company a b c d
sales 340(1.03)x 275(0.89)x 180(1.23)x 260(1.90)x rank the company sales by smallest to largest percent of increase and select the correct answer below.
a. a, b, c, d
b. a, d, b, c
c. b, a, c, d
d. c, b, d, a

C. B, A, C, D

Step-by-step explanation:

We know that the exponential growth function is represented by :-

, where r is the growth rate.

The exponential decay function is represented by:-

, where r is the decay rate.

Now for Company A the sales function=

⇒ It is a growth function with growth rate 0.03 or 3 %.

For Company B the sales function=

⇒ It is a decay function with decay rate 0.11 or 11 %.

Similarly for Company C, there is growth rate of 0.23 or 23% and for Company D, there is growth rate of .90 or 90 %

Thus, the rank according to the sales by smallest to largest percent of increase will be B, A, C, D

the answer is 5/14.

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
