Answer:
F(x) = 16
Step-by-step explanation:
F = 2. We find the value of -5x by inputting the value of the function into the x value.
F(x) = -5(2) + 6
F(x) = 10 + 6
F(x) = 16

Answer:
1.5seconds
Step-by-step explanation:
When the ball hits the ground, the height is equal to zero. So find t when H=0:
H=16t²+8t+80
0=16t²+8t+80
0=2t²+t+10
0=(2t-3)(t+2)
So (2t-3)=0, or (t+2)=0
So t=1.5 or t=-2. Time can't be negative though, so we take our answer as 1.5seconds
Answer:
45 pieces.
Step-by-step explanation:
First, if the ratio is 5 : 4, then is you multiply 4 x 5 to get 20, you need to multiply 5 x 5 to get 25.
Second, 20 + 25 = 45 which is the total amount of puzzle pieces.
Hope this helps!
