F(n) = f(n – 1) + f(n – 2); f(1) = 2; f(2) = 1.

Alex Ar [27]

f(n) is the nth term

Each term f(n) is found by adding the terms just prior to the nth term. Those two terms added are f(n-1) and f(n-2)

The term just before nth term is f(n-1)

The term just before the (n-1)st term is f(n-2)

----------------

For example, let's say n = 3 indicating the 3rd term

n-1 = 3-1 = 2

n-2 = 3-2 = 1

So f(n) = f(n-1) + f(n-2) turns into f(3) = f(2) + f(1). We find the third term by adding the two terms just before it.

f3) = third term

f(2) = second term

f(1) = first term

50 POINTS!!!!! HELP Soybean meal is 16% protein; cornmeal is 8% protein.How many pounds of each should be mixed together in orde

tia_tia [17]

The first thing we are going to do for this case is define variables.
We have then:
x: Amount of soybean meal
320 - x: quantity of cornmeal
We now write the equation that models the problem:
$0.16x + 0.08 (320-x) = 0.09 (320)
$
Rewriting we have:
$0.16x + 25.6 - 0.08x = 28.8
$
From here, we clear x:
$0.16x - 0.08x = 28.8 - 25.6

0.08x = 3.2

x = 3.2 / 0.08

x = 40$
Then, the amount of Soybean meal is:
$x = 40 lb
$
The amount of cornmeal is:
$320 - x = 320 - 40 = 280 lb
$
Answer:
cornmeal: 280 lb
Soybean: 40 lb.

Answer: 100

<u>Step-by-step explanation:</u>

<em>Reminder that log with no given base is actually log base 10</em>

$log_{10}10x=3\\\\10x = 10^3\\\\x = \dfrac{10^3}{10}\\\\\\x = 10^2\\\\x = 100$

PIT_PIT [208]

Answer:

1.25cups(8oz/1cup)=10 ounces

Step-by-step explanation:

we convert 1 1/2 quarts to cups. There are 4 cups in a quart:

1 1/2 quarts= 3/2 quarts (4 cups/ 1 quart)= 6 cups

Amount poured out:

6 cups- 3.5 cups= 2.5 cups

Amount poured in each cup:

2.5/2=1.25 cups
