<h3><u>
Answer:</u></h3>
The number of x-intercepts of the function are:
Two(2)
<h3><u>
Step-by-Step explanation:</u></h3>
The domain of a quadratic function is all real numbers and the range is y ≤ 2.
i.e. the graph of this quadratic polynomial will be a downward parabola whose vertex has y-coordinates less than or equal to 2.
Also we know that any upward or downward facing parabola have two x-intercepts i.e. the parabola crosses the x-axis at two points i.e. the y-coordinates of those two points are zero.
Hence, the number of x-intercepts of the function is:
Two(2)
Answer:
10 feet
Step-by-step explanation:
18-8=10 so the remaining 10 feet is what he needs to descend.
Answer:
B
Step-by-step explanation:
-t²+4t+5=0
t²-4t-5=0
t²-5t+t-5=0
t(t-5)+1(t-5)=0
(t-5)(t+1)=0
t=5,-1
when t=0,d=5
actual time it it is in air=5-1=4 seconds.
