Notice that <em>v</em> points into the third quadrant since both of its components are negative. If you want a vector to point in the same direction, it would need to have the same sign on its components. So C is the correct choice.
The factor of 1/√80 comes from normalizing the vector <em>v</em>. Its norm/magnitude is
|<em>v</em>| = √((-4)² + (-8)²) = √(16 + 64) = √80
so the unit vector that points in the same direction as <em>v</em> is simply <em>v</em> / |<em>v</em>|.

Answer:
4 yd/min
Step-by-step explanation:
Change 1 hour to 60 minutes.
(240 yd)/(1 h) = (240 yd)/(60 min) = 4 yd/min
Answer:
D - 192
Step-by-step explanation:
So the solve this, lets use the formula for area of a triangle:
b*h / 2 = A
b is the base, h is the height.
In this case, our base is 32, and our height is unknown.
To find it we must use pythagreons theorm:
a is half of the base in this case, since tecnically this iscoceles traingle(2 same sides) cut in half is 2 right triangles.
32/2 = 16
b is the unknown, and C is the hypotenuse(longest length) which is 20:
So we know b, whihc is our height, is 12.
Plugging this in:
32*12 / 2 = A
384 / 2 = A
192 = A
So the area of the triangle is 192.
Hope this helps!
Fraction means a part of something
we see
18 times a fraction is bigger or smaller or equal to 18
18 times a fraction means take a part ouf of 18
in this case
18 times 4/5=72/5=14.4
14.4 is less than 18
when you take a fraction of something, it becomes smaller, like if you take a slice of pizza or a fraction of the pizza, it becomes smaller

Answer: I think it is going to be 42.5
Step-by-step explanation: I think that because is you divide the 29 by 7.5 you get 3.86. Multiply the 11 by 3.86 and you get 42.46. If you round to the nearest tenth that would be 42.5
