For a regular polygon, it is number of sides times the length of one side.
If you know the polygon's area and apothem, then the perimeter formula is:
Perimeter = Area / (Apothem/2)

Answer: D) The y intercept is (0,1)</h3>
This can be confirmed by plugging x = 0 into the function to find that...
y = (1/2)^x
y = (1/2)^0
y = 1
Recall that any nonzero value to the 0th power leads to 1. So we can say x^0 = 1 as long as x is not zero.
---------------
Extra info (optional section):
- We can rule out choice A because negative x values work in the domain. For instance, if x = -1, then it leads to y = (1/2)^x = (1/2)^(-1) = 2. The negative exponent will apply the reciprocal operation to the base fraction.
- Choice B can also be ruled out because the range is y > 0. Or you could note that it is possible to get positive y values smaller than 1/2. Try x = 2 and you'll see it leads to y = 1/4 which is not greater than 1/2.
- Choice C is false as well. The function f(x) = (1/2)^x is decreasing throughout the domain. A graph visually would show this due to it going downhill when moving from left to right. A table of values is a non-visual way to see we have a decreasing function. The table would show that y decreases when x increases.
Answer:
x = -9

Answer:
<u>If you add 10 grams of sugar, you will get 40 grams of 27% sugar syrup (rounding to the next whole).</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
30 grams of sugar are 20% of sugar syrup bottle
2. What is the percentage of sugar if we add 10 grams of it?
We can find out the solution, using the Direct Rule of Three this way:
Sugar (grams) Percentage
30 20
40 x
************************************
30x = 40 * 20
30x = 800
x = 800/30
x = 26.67
<u>If you add 10 grams of sugar, you will get 40 grams of 27% sugar syrup (rounding to the next whole).</u>
