The answer would be D because if you notice the ratios between coordinates and their placement, the first transformation divides the coordinates by 8, or dilating it by a scale factor of 1/8. Then, in the second transformation, each of the coordinates' x-values increased by four, so it moves over four spaces to the right.
Answer:
its all smth if its a 150 all the side smtg
A. Obtuse and you can remember this because obtuse means not sharp, which is like a right angle.
Answer:
361/900
Step-by-step explanation:
The unit vector is given by the following formula:
a '= (a) / (lal)
Where,
a: vector a
lal: Vector module a
We are looking for the module:
lal = root ((- 15) ^ 2 + (8) ^ 2)
lal = 17
Same direction:
a = -15i + 8j
The unit vector is:
a '= (1/17) * (- 15i + 8j)
Opposite direction:
a = 15i - 8j
The unit vector is:
a '= (1/17) * (15i - 8j)
Answer:
a unit vector that has the same direction as the vector a is:
a '= (1/17) * (- 15i + 8j)
a unit vector that has the opposite direction of the vector a is:
a '= (1/17) * (15i - 8j)
