An example of consecutive odd integers is 23, 25, 27, and 29. Find four consecutive odd integers with a sum of 160. Show your wo
Andrew [12]
Step1: Define an odd integer.
Define the first odd integer as (2n + 1), for n = 0,1,2, ...,
Note that n is an integer that takes values 0,1,2, and so no.

Step 2: Create four consecutive odd integers.
Multiplying n by 2 guarantees that 2n will be zero or an even number.
Therefore (2n + 1) is guaranteed to be an odd number.
By adding 2 to the odd integer (2n+1), the next number (2n+3) will also be an odd integer.

Let the four consecutive odd integers be
2n+1, 2n +3, 2n +5, 2n +7 

Step 3: require that the four consecutive integers sum to 160.
Because the sum of the four consecutive odd integers is 160, therefore
2n+1 + 2n+3 + 2n+5 + 2n +7 = 160
8n + 16 = 160
8n = 144
n = 18

Because 2n = 36, the four consecutive odd integers are 37, 39, 41, 43.

Answer: 37,39,41,43

How do the graphs of f (x) = x 2 and g (x)= 3/4 x 2? relate?
Agata [3.3K]

Answer:

g(x) is a horizontal stretch of f(x) by \frac{3}{4} units.

Step-by-step explanation:

The given functions are;

f(x)=x^2

and

g(x)=\frac{3}{4}x^2

The parent function is f(x)=x^2.

The  function g(x)=\frac{3}{4}x^2 is a horizontal stretch of  f(x)=x^2 by \frac{3}{4} units.
