Answer:
r = 2.04%
Step-by-step explanation:
r = n{(A/P)^1/nt - 1}
Where,
r = interest rate = ?
n = number of periods = 12
A = future value = $22,960
P = present value = $20,960
t = time = 4 years
r = n{(A/P)^1/nt - 1}
r = 12{(22,960/20,987)^1/12*4 - 1}
= 12{(1.09)^1/48 - 1}
= 12{(1.09)^0.02 - 1}
= 12 (1.0017 - 1)
= 12(0.0017)
= 0.0204
r = 0.0204 × 100
= 2.04%
r = 2.04%

The value of k is 3
Solution:
Let us first find the equation of the line f(x).
The points on the line are (-6, -2) and (0, 4).
Here, 
Formula to find equation of a line:




Do cross multiplication.
y + 2 = x + 6
y = x + 4
f(x) = x + 4
Given that g(x) = f(kx)
g(x) = kx + 4
The point in the graph of g(x) is ( -2, -2).
g(-2) = k(-2) + 4
we know that g(-2) = -2.
-2 = -2k + 4
Subtract 4 from both sides.
-6 = -2k
Divide by -2 on both sides.
3 = k
k = 3
The value of k is 3.
The answer is -7,i hope this helps
