Answer:
Step-by-step explanation:
(3x – 5)(–x + 4)
(3x)(–x) + (3x)(4) + (–5)(–x) + (–5)(4).
-3x^2+12x +5x -20
-3x^2+ 17x -20
Independent variables are the things that change to see the affect of the dependant variable. In this case, the size of the last meal changes and affects the giraffes hunger level. The size of its last meal is the independent variable.
Answer:
8 seconds
Step-by-step explanation:
Given :
h(t) = -16t2 + initial height
Initial height = 1024 feets
By the time it hits the ground, h(t) = 0
Equation becomes :
0 = - 16t² + 1024
Solve for t
-16t² = 1024
t² = 1024 / -16
t² = 64
t = √64
t = 8
Hence, it will take 8 seconds
