If a=2, b=3 and c=4 then find the numerical value of a2+2abc+b2+c2

qaws [65]

a=2 b=3 and c=4. then,

a2+2abc+b2+c2

a2+2abc+b2+c2= 2^2+2×2×3×4+3^2+4^2

(replace value of a, b, c by2,3,4 respectively tgen solve)

= 4+48+9+16

= 77………………

Therefore, 77 is correct answer.

Jeremy completes eight extra credit problems on the first day and then for problems each day until the work is complete their 28

Novay_Z [31]

I THINK there is a typo. Instead of "for problems each day", i think it's "four problems each day."

Anyway, we need to find how many days it takes Jeremy to complete the paper.

If he completes 8 problems on the first day and 4 on the rest of the days, after the first day he'll have 28 - 8 = 20 more problems.

And since he does 4 every day with 20 problems: 20 / 4 = 5 days.

Which graph shows the end behavior of the graph of f(x) = 2x^6 – 2x^2 – 5?

Allushta [10]

Answer:

Refer the attached graph below.

Step-by-step explanation:

Given : Function $f(x) = 2x^6 -2x^2 -5$

To find : Which graph shows the end behavior of the graph of the given function?

Solution :

We have given the function $f(x) = 2x^6 -2x^2 -5$

To find the end behavior of the graph,

We need to find the degree of the given function and the leading coefficient.

Degree of the given function is the highest power of the variable.

Highest power of x is 6.

Degree = 6 ( an even degree)

Leading coefficient is the coefficient of highest power term.

We have highest power term is $2x^6$ .

So, the leading coefficient is 2 (Positive number)

For even degree and positive leading coefficient, end behavior is

$x \rightarrow \infty, f(x) = +\infty\\\\x \rightarrow -\infty, f(x) = +\infty\\$

Refer the attached figure below.
