To rewrite it as a single exponent we have to simply add the exponents since we have an equal base.
The answer is 9^7
Using proportions, it is found that the thickness of the icing between the layers, in inches, is of:
E 1 inch
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, there are six layers, each measuring 1.25 inches tall, hence the height of these layers is:
6 x 1.25 = 7.5 inches
Then the height of the icing between the layers is of:
13.5 - 7.5 = 6 inches
Six layers, hence each icing is of:
6/6 = 1 inch

Answer:
-10%
Step-by-step explanation:
price elasticity of demand = % change in demand / % change in price
Here, the "price" changes from 15 to 45, so its percent change is ...
((new value)/(old value) -1) × 100%
= (45/15 -1) × 100%
= 200%
The % change in demand is given as -20%, so the price elasticity is ...
price elasticity of demand = (-20%)/(200%) = -0.10 = -10%
Lets list the differences in the above list : these are 2 5 11 23 47:
call this list a
This last list has difference 3 6 12 24 (list b) so next number in this list is 48 and next number in list a is 47+48 = 95
In the original sequence therefore the next number is 89 + 95 = 184
so the list a and b are 2 5 11 23 47 95 List a
3 6 12 24 48 List b
The next number in list b is 96 and the next in list a is 96 + 95 = 191
so next number in sequence in question = 184 + 191 = 375
Next number in list b is 192 and next in list a = 191 + 192 = 383
So last number in sequence = 375 + 383 = 758
Next 3 numbers are 184, 383 and 758 answer
Sorry but I cant figure out the explicit rule at moment. I'll try and come back with it.
A) False because it is not a line (it is a parabola)
B) False because it fails the horizontal line test
C) False because it passes the vertical line test.
D) True because it passes the vertical line test but fails the horizontal line test.
Answer: D
