Jamie is measuring the growth of a bean plant in her garden. On the 1st day the bean plant is 2.5 inches tall. On the 4th day it is 7 inches tall and on the ninth day it is 14.5 inches tall. What will be the height of the bean plant on the 21st day if it continues to grow at a constant rate?

take it another

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it

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
