Stephanie is making lasagna for a aprty. the recipe uses: 1 1/2 teaspoons of basil, 2/4 teaspoons for salt, 1/8 teaspoons of peeper, 4 teaspoons of parsley. if she needs to double the recipe , how many teaspoons will she use of each ingredient?

3 teaspoons of basil, 1 teaspoon for salt, 1/4 teaspoons of pepper, and 8 teaspoons of parsley.

Step-by-step explanation:

Multiply each value by 2.

1 1/2 × 2 = 3

2/4 × 2 = 1

1/8 × 2 = 1/4

4 × 2 = 8

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt
