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
I get 603.19....so the last one....
Answer:
The woman bought 2 items at $12 each.
Step-by-step explanation:
Given that a woman bought a number of items for $ 24, and she realized that if she had bought 4 more items for the same money, she would have paid $ 8 less per item, to determine how many Items did she buy the following calculation must be done:
X = 24
X + 4 = 24
24/2 = 12
24/6 = 4
12 - 4 = 8
Therefore, the woman bought 2 items.
Answer:
b. 3 + (p x 6)
Step-by-step explanation:
i hope this helps :)
It would be 78 degrees because the angle opposite of it is the vertical angle, and vertical angles are congruent to each other.
