Answer:
it's the 2nd one
Step-by-step explanation:
d = 3 + at^2
-3 | -3
d - 3 = at^2
d - 3/a = t^2
√d - 3/a = √t^2
t = √d - 3/a
Answer:
A, B, F
Step-by-step explanation:
To solve this, you look at the powers of x and take either the square root (if it is to a power of 2) or the cube root (if a power of 3) of both sides to isolate x. For the first equation, you take the square root of 48, so A is correct. For the second one, you take the square root of 63, so B is correct. For the final equation, you take the cube root of 73, so F is correct.
We would be talking about velocity.
Scalar refers to a speed, but not a given direction.
For me, the easiest way to distinguish a scalar from velocity is to think about the mechanism of scales. A scale can go up and down, left and right, but it doesn't give a specific direction. In a Cartesian plane, the scale of (-4, 0) has the same scale as (4, 0) from the origin at (0, 0) because scale doesn't define a specific directional change in the same way magnitude doesn't have a specific direction.
Velocity, on the other hand, requires a direction because it is defined as the rate of change of an object from its initial position to its final position. In this instance, a direction is required as we need to define an object's acceleration or deceleration.
Answer:
36
Step-by-step explanation:
-7-2=-9
due to the absolute value symbol placed before and after "m - n"; your answer will be a positive; -9 = 9(+)--> times 4= 36
4|m-n| = 36
5.05 = 5.050
So, the numbers 5.05 and 5.050 are equal.
