Answer:
Growth factor is 1.2
Growth rate is 0.2
Step-by-step explanation:
Generally, we can have an exponential function as:
y = a(1 + r)^x
Where a is the initial value (y value when x = 0, which is 10)
r is the growth rate
at x = 2
14.4 = 10(1 + r)^2 •••••(i)
at x = 1
12 = 10(1 + r)^1 •••••(ii)
Divide i by ii
14.4/12 = 1 + r
1.2 = 1 + r
r = 1.2-1
r = 0.2
1 + r = 0.2 + 1 = 1.2
Answer:
3 < x < 17
Step-by-step explanation:
triangle inequality theorem: the sum of any two sides must be greater than the third
7 + 10 > x; x < 17
7 + x > 10; x > 3
