Answer:
f(t) = 15.06 m
Step-by-step explanation:
The relationship between the height of the rocket and the time after launch, t. In seconds is given by :
We need to find the maximum height the rocket will reach the ground.
When it reaches the ground,
f(t) = 0
So,
Maximum height,
f'(t) = 0
Put t = 1.63 in equation (1).
So, the maximum height of the rocket is 15.06 m.
F(x)=x^2+6x-2, vertex: (-3, -11)
First, put -(6)/2(1) or -b/2a.
You then get -3 as the X value of the vertex.
Next, insert -3 back into the equation to get the Y value of the vertex.
(-3)^2+6(-3)-2 = -11
You then have -11 as the Y value of the vertex.
Answer:
C) there are no solutions
Step-by-step explanation:
3x-6<3x+13
3x<3x+19
0<19
It is an indication that a mistake has been made, or that your imagination is working well.
_____
There are no physical units that correspond to the square root of a degree C. Degrees C is an arbitrary scale, so the square root of a number from that scale has no meaning. In the world of complex numbers, the square root of a negative number is imaginary. By attaching units of degrees C to the number, you have escaped the world of complex numbers and made your way to fantasy land.
In short, it is anything you want it to call it, as it is not anything that is defined in the realm of math or physics in the world we usually deal with.
