Answer:
x=17.771mm
Step-by-step explanation:
given a right triangle
to find vslue of x
solution (perpendicular) ² + (base) ² =(hypotenus) ²
using pythagorus theorem
(16.5)²+(6.6)²=(x)²
272.25+43.56=(x)²
315.81=(x)²
√315.81=x
x=17.771mm
I'm not sure why my previous answer was deleted, but heres another attempt.
The vector which opposes the vector with components [-4,3] would be [4,-3], because taking the opposite of each component gives the opposite direction. the length of [4,-3] (your new vector) is 5 because √((4)²+(-3)²) => √(16+9) => √25 = 5. This is half the necessary length, so to fix this we need to double both components, giving [2*4,2*(-3)] = [8,-6]
Final answer:
The vector with components [8,-6] has a length of 10 and opposes the direction of [-4,3].
I hope this helped clear up any confusion over my last answer. :)
A plot where each data value is split into a "leaf" (usually the last digit) and a "stem" (the other digits). The "stem" values are listed down, and the "leaf" values are listed next to them. This way the "stem" groups the scores and each "leaf" indicates a score within that group.
3 = -(-y + 6)
First, simplify the brackets. / Your problem should look like: 3 = y - 6
Second, add 6 to both sides. / Your problem should look like: 3 + 6 = y
Third, add 3 + 6 to get 9. / Your problem should look like: 9 = y
Fourth, switch the side. / Your problem should look like: y = 9
Answer: y = 9
