You can use a number line to compare values by on the line say that 4 is before 5 so it is saying that 4 is less than 5.
It’s not A or C. I think it’s D because of its positive slopes. If you have a graphing calculator, you can type this into y=
Answer: C.) 1.12 seconds
Step-by-step explanation:
Hi, to answer this question we have to substitute h=0 (when the rock hits the ground the height above it is 0) in the equation given:
h (t) = –16t2 + 20
Solving for t (time)
0= –16t2 + 20
16t2=20
t2=20/16
t=√1.25 =1.12 seconds (option C)
