A graph of f(x)=acos(bx) is shown, where b is a positive constant. Determine the values of a and b.

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.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
