During a jump, a sky diver reaches terminal velocity. Which forces are in effect during a sky dive, and are they balanced or unb

alanced when the jumper is at terminal velocity?(1 point)
Unbalanced. The force of gravity is stronger than the force of air resistance, which is why the sky diver is falling.

Balanced. The forces of gravity, air resistance, and speed are all in balance.

Balanced. The force of gravity is balanced with the force of air resistance.

Unbalanced. The force of air resistance is stronger than the force of gravity, which is why the sky diver is at terminal velocity.

The answer to this word problem usinf discriminant
solniwko [45]
\bf h=-9.8t^2+45t+1.2\implies 64.5=-9.8t^2+45t+1.2
\\\\\\
0=-9.8t^2+45t-63.3\\\\
-------------------------------

\bf \qquad \qquad \qquad \textit{discriminant of a quadratic}
\\\\\\
0=\stackrel{\stackrel{a}{\downarrow }}{-9.8}t^2\stackrel{\stackrel{b}{\downarrow }}{+45}t\stackrel{\stackrel{c}{\downarrow }}{-63.3}
~~~~~~
\stackrel{discriminant}{b^2-4ac}=
\begin{cases}
0&\textit{one solution}\\
positive&\textit{two solutions}\\
negative&\textit{no solution}
\end{cases}
\\\\\\
(45)^2-4(-9.8)(-63.3)\implies -456.36

the discriminant is a negative value, thus no solution for such quadratic, meaning if we use h=64.5 like we did, there's no "t" seconds at which point the ball hits the batting cage.

Name the plane that contains points A, D, and E.
Verdich [7]

Answer:

Plane T

Step-by-step explanation:

The given points A, D, and E are shown as being on the plane T as follows

Point a lays on the boundary of the boundary between plane S and plane T

Points D and E are points on a line DE that is on the plane T

Therefore, given that the line DE and the point A all lay on the same plane T, the plane that contains points A, D, and E, is plane T.

X=53+44+46? Is this right or no?
OleMash [197]

Answer:

X= 143°

Step-by-step explanation:

You could do it your way or as you can see, there's a right angle, which equals 90°, so you could either add 44+46+53 or 90+53. You get the same answer, which is 143°.
