Im pretty sure that the answer is B.
Answer:
C. 0, 1.29, -0.65
Step-by-step explanation:
The real solutions of the equation
is where the graph of
intersects the x-axis.
This means that we need to graph
using a graphing software.
From the graph shown in the attachment
,
, and
are the real solutions.
The correct choice is C
For the first one, you're answer would be AC. since C is also a right angle, and angle A is hypnotenuse to C
This is your answer

Answer:
D
Step-by-step explanation:
Differentiate the function and set it to zero:
f'(x) = -10x + 13
0 = -10x + 13
x = 1.3 seconds
Plug the x value into f(x):
f(1.3) = -5(1.3)^2 + 13(1.3) + 6 = 14.45 meters
