1. the dot is solid so it is x≥4
2. the dot is open so the answer is x≠4
Answer:
Step-by-step explanation:
7) 2ab + 4ac = 2*a*b + 2 *2 *a*c
= 2a(b + 2c)
8) ac - a²c² = c( a - a²c)
bc - abc = c(b - ab)
9) b²+ 4b - 5 = b² + 5b - 1b - 5
= b(b + 5) - 1(b + 5)
= (b +5)(b - 1)
b² + 8b + 15 = b² + 5b + 3b + 15
= b(b + 5) + 3(b + 5)
= (b + 5 )(b + 3)
Answer:
it depend on which angle is the sun is
Step-by-step explanation:
Answer:
Option (1)
Step-by-step explanation:
Equation of the given wave function,
f(x) = acos(bx)
Here, a = amplitude of the wave
Period of the wave =
From the graph attached,
Amplitude =
=
= 4
Period of the wave = π - 0
= π
From the formula of the period,
Period =
b = 2
Therefore, a = 4 and b = 2.
Option (1) will be the answer.
1. Volume is 8
2. Surface Area is 24
