Convert to vertex form:-
= -0.04(x^2 + 39x)
= -0.04( (x + 19.5)^2 - 380.25)
vertex is at -0.04 * -380.25 = 15.21 yards
Maximum height is about 15.2 yards
Answer:
3
Step-by-step explanation:
2x + 3 = -x + 12
subtract 3 from both sides
2x = - x + 9
add x to both sides
3x = 9
divide by 3
x = 3
Answer:
4x² + 4x + 1
Step-by-step explanation:
We know that (a + b)² = a² + 2ab + b², therefore, (2x + 1)² = 4x² + 4x + 1.
Answer:
Step-by-step explanation:
To find the volume of this solid, multiply the base area by the height:
V = (25 cm²)(4 cm) = 100 cm³
