Answer: 40 degrees
Step-by-step explanation:
The angles of a triangle add to 180 degrees.
44 + 96 + x = 180
x = 40 degrees
Answer:


And since the time can't be negative we have that:

So the answer for this case would be after 10.36 seconds the rocket will hit the ground
Step-by-step explanation:
For this case we have the function of the height in terms of the time givenby:

And we want to known when the rockect hit the ground and for this case we need to solve the equation 

And as we can see we have a quadratic equation like this one:

Where: 
And the general solutions are given by:

If we replace the values that we have we got:


And since the time can't be negative we have that:

So the answer for this case would be after 10.36 seconds the rocket will hit the ground
Answer:
used Pythagorean theorem to figure this out
a² + b² = c²
BC ~ 11.5 mm
Step-by-step explanation:

Answer:
When a graph has 2 x-intercepts, it will have positive discriminant & when a graph has NO x-intercepts, it will have negative discriminant.
Step-by-step explanation:
In a quadratic equation, the discriminant is the value of
. This is "under the square root sign" when solving using quadratic formula.
Thus, there can be 3 possibilities:
1. Discriminant is 0 ( 2 equal real roots - meaning 1 touching point at the x-axis in the graph)
2. Discriminant can be positive ( 2 distinct real roots - meaning 2 cutting point in the x axis)
3. Discriminant can be negative ( 2 complex roots - meaning NO cutting point in x-axis)
Thus, when a graph has 2 x-intercepts, it will have positive discriminant & when a graph has NO x-intercepts, it will have negative discriminant.
Answer:
Hey there!
12^2+5^2=c^2
144+25=c^2
c=13
Let me know if this helps :)
