Hello there!
1. Okay. So 70% is positive, so it is a corresponding growth. 70% is 0.7 in decimal form. C and D are both eliminated, because that's too large. When something grows by 70%, that is less than double. 0.7 is not right either, because that's more of a decay than a growth. The only answer that makes sense id 1.70, because you are going up, and adding 1 to decimal form brings you to the decimal that when multiplied will bring you to the total. The answer is B: 1.70.
2. So, -75% is negative, so it is a decay factor. A is eliminated, because it makes no sense and B is out, because that represents growth, not decay. You lose 75% of the amount overtime compounded, but you still have 25% that remains. To find that amount, you would subtract that amount from 1 to get the decay. 1 - 0.75 is 0.25. The decay factor is 0.25. The answer is D: 0.25.
Hi!
<em>To calculate the rate of change between days 4 and 6, we simply take those points, (4, 1503) and (6, 2196) and use the equation in the picture below:</em>
<em />
Now, when we plug it in the equation, it looks like this:
Therefore, your answer is 346.5 or, rounded, 347.
<em><u>Meaning, your answer is C</u></em>

Hope this helps and have a great day! :D
Answer:
11 and 12
Step-by-step explanation:
x=smaller
y=larger
2y=3x-9 x+1=y
2(x+1)=3x-9
2x+2=3x-9
11=x
11+1=y
12=y
36....we need to break this down...12 * 3 = 36
12 * 3....we can break this down because 12 is not prime...4 * 3 = 12
4 * 3 * 3...we can break the 4 down because it is not prime
2 * 2 * 3 * 3 <==== prime factorization
$530.40/4= $132.60
$132.60 x 3=$397.80
Or
$530.40 x .75= $397.80
