Let s be the speed of the plane; and w be the speed of the wind. Then:
5s-5w=2950
9s+9w=7650

45s-45w=26550
45s+45w=38250
90s=64800
s=720
w=

How to tell if a table is a exponential decay function an exponential growth function or neither
aliya0001 [1]

Answer:

Exponential function: a*b^x

if B is less than 1, it is a decay function

if B is more than 1, then it is a growth function  

if B is 0, then the function neither decreases nor increases

Example 1: 100*0.14^x

The y-intercept is decreasing by 86%

Example 2: 3000*1.14^x

The y-intercept is increasing by 14%

Example 3: 400*0

The y-intercept is neither decreasing nor increasing

Going back to the function, <u>a</u> is the y-intercept, and <u>b</u> is the rate

<u>I hope this will help you, I just started to learn about exponential functions..</u>

Original cost minus the 10% discount
Dmitrij [34]

Hi! I will try my best to answer your question, the wording provided is unclear.

If the 10% of the original cost of something is $1.50, then the total cost is $15.00.

Assuming this is the discounted price, which would be 90% of the original cost, the original cost would be $16.67.

When doing blood testing for a viral infection, the procedure can be made more efficient and less expensive by combining partial
Verdich [7]

Answer: 0.271

Step-by-step explanation:

Probability of complement of an even is 1 decreased by the probability of the event

P(At least one) =1 - P(none)

The probability that of testing negative is 0.9 because the probability of testing positive is 0.1

P( at least one) = 1 - P(none) = 1 - (0.93^3) = 0.271
