Maths equation : solve (2 - x)² < 4/25

ipn [44]

Answer:

8/5 < x < 12/5

Step-by-step explanation:

(2 - x)² < 4/25

2 - x < ±2/5

2 - x < 2/5

-x < -8/5

x > 8/5

2 - x > -2/5

-x > -12/5

x < 12/5

Therefore, your answer is 8/5 < x < 12/5

Which choice is equivalent to the quotient shown here for acceptable values of x?

OleMash [197]

<span>Sqrt(5x) * Sqrt(x) + 3
= 5^(1/2) * x^(1/2) * x^(1/2) + 3
= 5^(1/2) *x +3
=5^(1/2)*x^(2/2) +3
=Sqrt(5*x^2) +2

So the answer is A </span>

Solve the system of equations by finding the reduced row echelon form of the augmented matrix. Write the solutions for x and y i

Gwar [14]

Answer:

The solutions for the given system of equations are:

$\left \{ {{x=-5} \atop {y=12-4z}} \right.$

Step-by-step explanation:

Given the equation system:

$\left \{ {{3x+y+4z=-3} \atop {-x+y+4z=17}} \right.$

We obtain the following matrix:

$\left[\begin{array}{cccc}3&1&4&-3\\-1&1&4&17\end{array}\right]$

<u>Step 1:</u> Multiply the fisrt row by 1/3.

$\left[\begin{array}{cccc}1&\frac{1}{3} &\frac{4}{3}&-1\\-1&1&4&17\end{array}\right]$

<u>Step 2:</u> Sum the first row and the second row.

$\left[\begin{array}{cccc}1&\frac{1}{3} &\frac{4}{3}&-1\\0&\frac{4}{3} &\frac{16}{3}&16\end{array}\right]$

<u>Step 3:</u> Multiply the second row by 3/4.

$\left[\begin{array}{cccc}1&\frac{1}{3} &\frac{4}{3}&-1\\0&1 &4&12\end{array}\right]$

<u>Step 4:</u> Multiply the second row by -1/3 and sum the the first row.

$\left[\begin{array}{cccc}1&0 &0&-5\\0&1 &4&12\end{array}\right]$

The result of the reduced matrix is:

$\left \{ {{x=-5} \atop {y+4z=12}} \right.$

This is equal to:

$\left \{ {{x=-5} \atop {y=12-4z}} \right.$

These are the solutions for the system of equations in terms of z, where z can be any number.

A) find a cartesian equation for the curve described by the given polar equation. r =3 sin g

Radda [10]

Recall that r^2 = x^2 + y^2, so that r = sqrt(x^2+y^2).

y
r = 3 sin g becomes sqrt(x^2+y^2) = 3*-----------------------
sqrt(x^2+y^2)

Squaring both sides,

9y^2
x^2+y^2 = -----------------
x^2 + y^2

If this is correct (and I'm not convinced that it is), then (x^2+y^2)^2 = 9y^2
shows the relationship between x and y. Can anyone improve on this result?
