BRAINLIAST IF ANSWERED DETAILED AND PRECISE

If we were to create a plan (reducing the microplastics in the ocean), how can we have an effective solution, but also keep the cost low?

I KNOW THIS HAS NOTHING TO DO WITH MATHEMATICS... IT'S ENGINEERING, help me answer it, please:'(

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 23.39370079

step-by-step explanation:

wouldn't that be a) 1

4=4x then divide 4 on both sides and you get x=1
