cos K = 12/13
Answer:
Answer: Janet is 16, and David is 11.
Step-by-step explanation:
Let the ages be j and d.
j = d + 5
j + d = 27
Substitute d + 5 for j in the second equation.
d + 5 + d = 27
2d + 5 = 27
2d = 22
d = 11
Substitute 11 for d in the first equation.
j = d + 5
j = 11 + 5
j = 16
Answer: Janet is 16, and David is 11.
Step-by-step explanation:
We know that
cos 2x = 2cos²x - 1
So we have
Substituting 
Answer:
The circumference would be 12*3.14/2=18.84
The equation in point slope form is given as y+3 = -5/8(x-4)
<h3>Equation of a line</h3>
The formula for calculating the equation of a line in point-slope form is expressed as:
y-y1= m(x-x1)
Given the coordinate point
Slope = 2-(-3)/-2-4
Slope = 5/-8
Determine the equation
y-(-3) =-5/8(x-4)
y+3 = -5/8(x-4)
Hence the equation in point slope form is given as y+3 = -5/8(x-4)
