Answer:
f(6) = -5
f(x) = 0 and x=1 and x=5
Step-by-step explanation:
f(6) is the value when x=6
looking at the graph when x=6 f(6) = -5
f(x) = 0 means the y value is 0 This occurs when x = 1 and x=5
Answer:
no
Step-by-step explanation:
it does not matter only when you are adding or subtracting fractions you need the same denominator.

Step-by-step explanation:
Figure a is a convex pentagon, a convex pentagon is a pentagon that does not have an internal angle greater than

An easier thing to remember is that it does not have an angle pointing inwards like b, none of its angles/edges point toward the shape/inside
Answer:
3 seconds
Step-by-step explanation:
You want to set h(t)=3, then take the root such that t≠0. You would have:
3=3+48t−16t^2
Let's solve your equation step-by-step.
3=3+48t−16t2
Step 1: Simplify both sides of the equation.
3=−16t2+48t+3
Step 2: Subtract -16t^2+48t+3 from both sides.
3−(−16t2+48t+3)=−16t2+48t+3−(−16t2+48t+3)
16t2−48t=0
Step 3: Factor left side of equation.
16t(t−3)=0
Step 4: Set factors equal to 0.
16t=0 or t−3=0
t=0 or t=3
3 makes more sense than 0 because the ball can't have been in the air for 0 seconds.
So the ball was in the air for 3 seconds.
