1) (3.8 * 10^3) * (9.4 * 10^-5) = 0.3572 = 3.6 * 10^-1
2) (4.2 * 10^7) * (7.4 * 10^-2) = 3.1 * 10^6
3) (8.6 * 10^-6) * (7.1 * 10^9) / (4.1 * 10^ -2) * ( 2.8 * 10 ^-7) = 5.3 * 10^-6
4) 4.2 * 10^-1
Sorry for not putting my work for number 4. Hope this helps!
Answer: 196 m
Step-by-step explanation:
Use midpoints and bisectors to find the halfway mark between two coordinates. ... Midpoint Formula: For two points, (x1,y1) and (x2,y2),
A = I * w
divide by w
I = A / w
Your answer is the third choice
