Answer to problem 1 is (9,9)
Answer to problem 2 is (0,-4)
----------------------------------------------------
Explanation:
To find the component form, they basically want the translation rule. To find the translation rule, we subtract the coordinates tip - head
In general, if we have two vectors M and N such that
M = (a,b)
N = (c,d)
then
vector MN = (c-a, d-b)
Applying this to the vector CD gives us
vector CD = (7-(-2), 10-1) = (7+2, 10-1) = (9, 9)
Basically meaning that we shift point C nine units to the right and nine units up to get to point D
Similarly,
vector RS = (-4-(-4), -3-1) = (-4+4, -3-1) = (0,-4)
so we shift point R four units down to get to point S
Classica aplicação de regra de 3:
é dito que: 1 milha = 1,6km
Logo, eis a regra de 3:
milha km
1 -------- 1,6
X -------- 240
1,6X = 240.1
X = 240/1,6
<h3>X = 150milhas</h3><h3 />
Logo 240km equivalem a 150milhas
The answer to your question is 8
Answer:
83°
Step-by-step explanation:
Since BD and XY are parallel then 83 and x are corresponding angles.
