Answer:
47.5 Meters
Step-by-step explanation:
Find where the derivative changes from positive to negative (local maximum)
h(t)=
h'(t)=
Find where the derivative equals zero
Theres no spot where the derivative wont exist because its a polynomial.
-12t=-30
t=
Ill stop here because this is a parabola opening down and this is the only spot where there will be a horizontal tangent line so this is the x-coordinate of the vertex. AKA you don't need to test positive and negative on both sides.
Now plug into original equation
h(2.5)=
=-37.5+75+10
=47.5
Complete Question
Apabila a =2 b = 3 dan c =12 tentukan nilai dari bentuk :
a⁶× b⁴ × c²
(ab)² ×c³
Answer:
1) a⁶× b⁴ × c² = 746496
2) (ab)² ×c³ = 62208
Step-by-step explanation:
a =2, b = 3, c =12
a) a⁶× b⁴ × c²
2⁶× 3⁴ × 12²
= (2 × 2 × 2 × 2 × 2 × 2) × (3 × 3 × 3 × 3) × (12 × 12)
= 64 × 81 × 144
= 746496
b) (ab)² ×c³
(2 × 3)² × 12³
= 6² × 12³
= (6 × 6 )× (12 × 12 × 12)
= 36 × 1728
= 62208
I am not really sure if the figure that its asking is a shape.But this is what i've got for you:
first figure is an obtuse scalene triangle.
second figure is a simple square.
