the formula is a_{1}+(n-1) d
so a_{1} would be the first number in the sequence, which would be 13 in problem 9.
13+(n-1)d
then you put in n, which is 10 (it represents which number in the sequence you're looking for, for example 16 is the second number in the sequence)
13+(10-1)d
then you find the difference between each number, represented by d which in this case is 3
13+(10-1)3
13+(9)3
13+27=
40
The choices can be found elsewhere and as follows:
<span>A.Acid(tartness)
B.Tartness(acid)
C.Tartness(lemon)
D.Lemon(acid)
I think the correct answer from the choices is option B. </span>The tartness of a lemon (which depends on the concentration of citric acid) can be represented by Tartness(acid) or tartness as a function of acidity.
Answer:
The length of one side of the jewelry box is 8 inches
Step-by-step explanation:
we know that
The volume of a cube is equal to
where
b is the length side of the cube
In this problem we have
substitute in the equation and solve for b
so
![b=\sqrt[3]{512}](https://tex.z-dn.net/?f=b%3D%5Csqrt%5B3%5D%7B512%7D)
f(a + 2) for f(x) = (3 + x) / (x - 3)
Substitute a + 2 for x in our equation
f(a + 2) = (3 + (a + 2)) / ((a + 2) - 3)
Combine like terms
f(a + 2) = (5 + a) / (a - 1).
This is as far as you can go.
C is the correct answer choice
Just set the perimeter equation equal to each other and put the values in that you know and solve
