In January of 2001, Karen bought a professional camera for $4550. It is expected to decrease in value by 6.8% per year A. Set up the equation representing the situation.

B. USE THE GRAPHING METHOD to solve the equation you wrote in part A to PREDICT THE YEAR the value of Karen's camera will be first worth under $2000. IT IS REQUIRED THAT YOU INCLUDE A GRAPH THAT HELPS YOU FIND THE ANSWER.

what's the question?

step-by-step explanation:

there is no question.

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

the answer is: -22 also a
