Solution:

we are given that

John is 3 years older than Jim. Jim is 4 years less than half of Dana’s age.

Let the age of Jim be x years then we can say

Age of John=x+3

If diana Age is D then

x=D/2-4

It can be re-wriiten as

Diana age D=2x+8

Given that  their ages add up to 167

x+x+3+2x+8=167\\
\\
4x+11=167\\
\\
4x=167-11\\
\\
4x=156\\
\\
x=39\\

Hence jim is 39 nyears old, John is 39+3=42 years old. and Diana is 2*39+8=78+8=86 years old.

MrRa [10]

Answer:

\sqrt{65}

Step-by-step explanation:

distance between two points:

d=\sqrt{(x_{2}-x_{1})^{2}+( y_{2}-y_{1})^{2}}

we have:

d=\sqrt{(-4-(-5))^{2}+(-5-3)^{2}} \\\\d=\sqrt{1^{2}+(-8)^{2}} \\\\d=\sqrt{65}

Determine the graph of the sinusoid with amplitude of 4 and period of 2π/3
DiKsa [7]

Answer:

Option b.

y = 4 sin (3x)

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.

Please see the attached image below, to find more information about the graph

The period is  

T = 2π/3

This means the frequency in radians is

W = 2π/T = 3

The equation is either:

y = 4 cos(3x)

y = 4 sin (3x)

The correct answer is

Option b.

y = 4 sin (3x)
