Which is an extraneous solution of the exponent x+sqrtx=6

1 answer:

3 0

First, we can simplify it down.
x = (-x + 6)^2
Then, you should have x - ( $x^{2}$ - 12x + 36).
Factor it to get x = 4 or 9. 4 works in the original equation but 9 does not.

What is the maximum number of possible extreme values for the function, F(x)=x^4+x^3-7x^2-x+6?

Arturiano [62]

Coming from a 6th grader but I hope this is right!

Polynomials of degree greater than 2 can have more than one max or min value. The largest possible number of minimum or maximum points is one less than the degree of the polynomial. The following examples illustrate several possibilities.

since the degree is 4

number of possible extreme values = 4 -1 = 3

An oven heating element turns on when the internal temperature falls to 20 degrees below the set temperature and turns off when

son4ous [18]

Answer:

The range of the oven is $385\leq T\leq 410$

Step-by-step explanation:

Consider the provided information.

The internal temperature falls to 20 degrees below the set temperature and turns off when the temperature reaches 5 degrees above the set temperature.

You preheat the oven to 405 degrees before putting a cake in and baking it for an hour at 405.

The internal temperature falls to 20 degrees, therefore the lowest set can be:

405-20=385 degree.

The temperature reaches 5 degrees above the set temperature 405, therefore the upper set is: 405+5=410 degree.

Hence, the temperature will be lying between 385 degree and 410 degree.

This can be written as: $385\leq T\leq 410$

Hence, the range of the oven is $385\leq T\leq 410$

13 multiplied by the sum of 4 and11. Now reverse the result and add it to the earliest result and then multiplied it by 13

Kobotan [32]

Step-by-step explanation:

I am not critically certain but the ways you have jotted down your enquiry..

<h2>I assume is</h2>

13 × (4×11)

13 × 44

=572 - 44= 528

528+13 =541

541 ×13=7033
