to find the product 3 3/8 * 4 1/9.tara rewrote 3 3/8 as 17/8 amd 4 1/9 as 13/9. she multiplies the fractions to find the product
Ymorist [56]

Answer:

The error Tara made is she rewrote incorrectly 3 3/8 as 17/8 and 4 1/9 as 13/9,

the corrected number can be rewrote as 3 3/8 as 27/8 and 4 1/9 as 37/9.

Step-by-step explanation:

To find the Product of:

3\frac{3}{8}\times 4\frac{1}{9}

The Number can be rewrote as,

\frac{3\times8+3}{8}\times \frac{4\times9+1}{9}\\\\\frac{24+3}{8}\times \frac{36+1}{9}\\\\\frac{27}{8}\times \frac{37}{9}

Tara made error here she rewrote the number incorrectly 3 3/8 as 17/8 amd 4 1/9 as 13/9.

Now multiplying the fraction we get

\frac{999}{72}

Because she rewrote incorrectly which led her answer to multiplication of fraction, the product too was incorrect which she wrote as 221/72.

Given the function f(x) = x^3 + x^2 − 2x + 1, what is the resulting function when f(x) is shifted to the left 1 unit?
Vikki [24]
The resulting function g(x) is ...
  g(x) = f(x +1)
  g(x) = (((x +1) +1)(x +1) -2)(x +1) +1
    = ((x +2)(x +1) -2)(x +1) +1
    = (x² +3x)(x +1) +1
    = x³ +4x² +3x +1

The shifted function g(x) is ...
  g(x) = x³ +4x² +3x +1
