Answer:
t = 0.35 seconds
Step-by-step explanation:
We have given the equation:
d=1/2gt²
where,
g = 9.8 m/s²
d = 0.6 m
t = ?
Now put the values in the given formula:
d*2/g = t²
0.6*2/9.8 = t²
1.2/9.8 = t²
0.12245 = t²
Now find the square root of both sides
√t² = √0.12245
t = 0.35 seconds
Answer:
i would assume its A
Step-by-step explanation:
For something to be a function, each input (x value) can only have ONE output (y value)
If an input has multiple outputs, it is not a function.
so the last graph represents a function (parabola going down)
You remember from SOH CAH TOA that
.. Cos = Adjacent/Hypotenuse
.. cos(C) = 80/82 = 40/41 . . . . . . . . . . . seems to match the last selection
Answer:
Step-by-step explanation:
It is a linear equation and the gradient equation is given as:
y=mx+c
Where m is the gradient and c is the y intercept
-3x+2y=1
2y=1+3x
Dividing all through by 2
y=1/2 + 3x/2
Therefore the gradient of this linear equation is 3/2 and the y intercept is 1/2
