Cedric completed the square for the quadratic expression 5x^2−40x+15 in order to determine the minimum value of the expression,

Olegator [25]

Answer:

Step 3 is not correct (should be $(x-4)^2$ , not $(x+4)^2$

Step-by-step explanation:

The expression that we have to simplify is:

$5x^2-40x+15$

We proceed step-by-step, in order to find the mistake did by Cedric:

1) First, we factorize the 5 outside:

$5(\frac{5x^2}{5}-\frac{40x}{5}+\frac{15}{5})=5(x^2-40x+3)$ --> this step is correct

2) We add +16 and -16 inside the brackets:

$5(x^2-8x+16-16+3)$ --> this step is correct

3) We rewrite the term $(x^2-8x+16)$ as the square of a bynomial, which is $(x-4)^2$ , so the expression becomes

$5((x-4)^2-16+3)$ --> we notice that this step is wrong: in fact, Cedric wrote $(x+4)^2$ , which is not correct.

4) Now we continue: we rewrite -16+3 as -13,

$5((x-4)^2-13)$

5) Finally, we multiply the 5 by the terms in the bracket:

$=5(x-4)^2-65$

response error.

Step-by-step explanation:

A response error shows the lack of accuracy in the customer responses to the survey questions. A response error can be caused by a questionnaire that requires framing improvements, misinterpretation of questions by interviewers or respondents, and errors in respondents' statements. Some responses are influenced by the answers provided to previous questions, which introduces response bias.

larisa [96]

Compute the ending balance of the opening balance for the first day then add deposited amount after that compute the balance
The formula is
A=p (1+r/k)^kt
A future value
P present value
R interest rate
K compounded daily 365
T time in days x/365

To sum up kt =365×(1/365)=1 day
A=900×(1+0.021÷365)^(1)
A=900.0517808219... the balance before the amount deposited is added

Now add the amount deposited
900.0517808219+76.22
=976.2717808219

Calculate the balance using the same formula
A=976.2717808219×(1+0.021÷365)^(1)
A=976.33. ..answer

Hope it helps!
