Extraneous solutions are the values that we get when solving equations which aren't really solutions to the equation.

<h3>What are extraneous solutions?</h3>

Your information is incomplete. Therefore, an overview will be given.  An extraneous solution is the root of a transformed equation which is not a root of the original equation since it was excluded from the domain of the original equation.

The reason extraneous solutions exist is simply that some operations produce extra answers, and these operations are a part of the path to solving the problem.

Consider the function f(x) = 20/√x and its second-degree polynomial P2 (x) = 20 - 10(x-1) + 7.5(x-1)^2 at x=0.8. Compute the val
krok68 [10]

Answer:

f (0.8) = 22.3607 and P_{2} (0.8) = 22.300.

Step-by-step explanation:

According to the statement, f (x) = \frac{20}{\sqrt{x}}  and  P_{2}(x) = 20 - 10 (x-1) + 7.5 (x-1) ^ 2. Based on these definitions, at x=0.8 produce:

f (0.8) = \frac{20}{\sqrt {0.8}} = 22.3607.  On the other hand, you have to:

P_{2} (0.8) = 20 - 10 (0.8 -1) +7.5 (0.8 -1)^2

P_{2} (0.8) = 20 - 10 (-0.2) +7.5 (-0.2)^2 = 22.300

Then, it can be affirmed that f (0.8) = 22.3607 and P_{2} (0.8) = 22.300.

The radius of a circle is 10. Using π, which equation expresses the ratio of the circumference of the circle to the circle's dia
Liula [17]

Answer:

π = C / d

Step-by-step explanation:

The circumference of a circle is given by the general formula;

C = 2 * π * r .... or C = π d  (r = radius, d = diameter)

We can easily modify the second formula to isolate π in order to express the circumference in relation to the diameter:

π = C / d

To obtain π, you need to divide the circumference by the diameter.

We're used to think about the circumference in terms of radius... but since we deal with 2 * r * π and that 2 * r = d...  it's also convenient to use the diameter.

Quadrilateral RPQS is a rectangle. Label the missing measures.
Taya2010 [7]

Answer:

Part 1) PR=9\ units

Part 2) PQ=12\ units

Part 3) PS=15\ units

part 4) QR=15\ units

Part 5) RT=7.5\ units

Step-by-step explanation:

we know that

In a rectangle opposite sides are parallel and congruent

The measure of each interior angle is 90 degrees

The diagonals are congruent and bisect each other

step 1

Find the length of side PR

we know that

PR=QS ----> by opposite sides

we have

QS=9\ units

therefore

PR=9\ units

step 2

Find the length of side PQ

we know that

PQ=RS ----> by opposite sides

we have

RS=12\ units

therefore

PQ=12\ units

step 3

Find the length of diagonal PS

we know that

PS=2PT---> the diagonals bisect each other

we have

PT=7.5\ units ---> given problem

therefore

PS=2(7.5)=15\ units

step 4

Find the length of diagonal QR

we know that

QR=PS---> the diagonals are congruent

we have

PS=15\ units

therefore

QR=15\ units

step 5

Find the length of RT

we know that

QR=2RT---> the diagonals bisect each other

we have

QR=15\ units

substitute

15=2RT\\RT=7.5\ units

Max has a science test on Thursday. On Monday he studied 2/9 of the material. On Tuesday he studied 1/4 of the remaining materia
wolverine [178]

Answer:

The answer to your question is:

Fraction he has review =  17/36

Fraction he have to study = 19/36

Step-by-step explanation:

Data

Monday studied = 2/9

Tuesday = 1/4

Fraction he has review = ?

Fraction he has left = ?

Process

As the denominator is 9, consider the whole is 9.

Then:    Fraction left on Monday = 9/9 - 2/9

                                                      = 7 / 9

Fraction left on Tuesday = 7/9 - 1/4

                                         = (28 - 9) / 36

                                        = 19 / 36

Fraction he has review =  17/36

Fraction he have to study = 19/36
