F(x)=5x^3-2x^2+3
=5 2^3 - 2 2^2 +3
=5 (8) - 2 (4) +3
= 40 - 8 + 3
= 35
answer is A.35

__________
Answer: 24.2° SouthWest
<u>Step-by-step explanation:</u>
First step: DRAW A PICTURE of the vectors from head to tail <em>(see image)</em>
I created a perpendicular from the resultant vector to the vertex of the given vectors so I could use Pythagorean Theorem to find the length of the perpendicular. Then I used that value to find the angle of the plane.
<u>Perpendicular (x):</u>
cos 35° = adjacent/hypotenuse
cos 35° = x/160
→ x = 160 cos 35°
<u>Angle (θ):</u>
sin θ = opposite/hypotenuse
sin θ = x/320
sin θ = 160 cos 35°/320
θ = arcsin (160 cos 35°/320)
θ = 24.2°
Direction is down (south) and left (west)
Answer:
10x + 12y = 15
12y = 15 - 10x
y = 15 - 10x / 12 (15 minus 10x all divided by 12) [Answer]
