Tan(30o)= ?/25
25 * tan(30o) = ?
? = 14.4
8-3x=5*2
8-3x=10
-3x=10-8
-3x=2
x=-2/3
The formula for the volume of a cube is:
v=s³
Where v=volume and s=the length of a side
Since we know that the length of a side of the gift box is 15cm, we can solve for the volume.
v=15³=3375cm³
Answer: V=3375cm³
Answer:
B., E.
Step-by-step explanation:
what was the difficulty ? this is just to understand the movement of a thrown rock.
what happens, when you throw a rock through the air ? it will first move up a little bit, reaches a maximum height, and then drops down again.
that is what the graphic shows.
so, can A. be correct ? no. as we move from 0 seconds to the right (time passes) the height of the rock increases first (before decreasing again later on).
can C. be correct ? no, it would mean that the function would look the same on both sides of the x-axis. this is clearly impossible.
can D. be correct ? no, nowhere in the graph is the height (= the functional value, the y to the x) negative.
can F. be correct ? no, we clearly see the maximum height at 1.5 seconds. at 3 seconds the height is actually at its minimum.
