Assuming that the population growth remains constant, write an exponential equation to determine the population some unknown number of years after 1999. The annual rate of change is 0.90% and the population is 272,690,813.

10.4 inches

step-by-step explanation:

2x2x2.6

the answer is 11.2 (i know i’m late)

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

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
