Acceleration and velocity</h3>
=================================
Explanation:
Distance is a scalar. It's simply a single number. It does not include a direction. We can rule out choice A. If you wanted direction connected to distance, then it would form a displacement vector.
Acceleration is a vector because velocity is a vector, and vice versa. The two are tied together. The acceleration is the change in velocity. You can think of it as acceleration = velocity/time.
Speed is not a vector. It's a single value just like distance is. If you want to have speed tied to a direction, then you would form a velocity vector.
Answer:
630/30=21 so 21 stacks
Step-by-step explanation:
2.) 7a^2 + 50a + 7 = 7a^2 + a + 49a + 7 = a(7a + 1) + 7(7a + 1) = (a + 7)(7a + 1)
3.) 3x^2 + 11x - 20 = 3x^2 - 4x + 15x - 20 = x(3x - 4) + 5(3x - 4) = (x + 5)(3x - 4)
4.) x^2 + 7x - 18 = x^2 - 2x + 9x - 18 = x(x - 2) + 9(x - 2) = (x + 9)(x - 2)
Answer:
4 units
Step-by-step explanation:
see attachment for the missing figure.
to find the value of AY or x
We'll use intersecting chord theorem i.e the product of line segment of each chord are equal.
From the figure, we can say that:
BY x YD = AY x YC
Therefore, AY = 4 units
