Hello : 
<span>odd function is :  </span>d)  f(x)=6x3+2x
because for all x in R  : f(-x) = 6(-x)3 +2(-x)
                                             = -6x3-2x.........(-x)3= -x3
                                             = -(6x3+2x)
f(-x) = -f(x)

The value of a rare baseball card A appreciated by 20 percent over a five year period; over the next five years, the value plumm
lbvjy [14]
<h2>Answer:</h2>

<em><u>Percent value of A with respect to Percent value of B is,</u></em>

30\%

<h2>Step-by-step explanation:</h2>

In the question,

Let us say the value of the Baseball card A and B initially is = 100x

So, for Baseball card A in first 5 years percent increase = 20%

So,

Value after 5 years = 100x + 20% of 100x = 120x

<u>After 5 more years,</u>

Percent decrease = 50%

So,

<u>Value at the end of 10 years = 120x - 50% of 120x = 60x</u>

Now,

For Baseball card B, Percent increase in 10 years = 100%

So,

<u>Value of card B = 100x + 100% of 100x = 200x</u>

So,

<em><u>Percent value of A with respect to Percent value of B is,</u></em>

\frac{60x}{200x}\times 100=30\%

Find the equation of the circle with center (4,5) which passes through the y-intercept of the line 5x-2y+6=0​
Elena-2011 [213]

Answer:

(x-4)^2 + (y-5)^2 = 20

Step-by-step explanation:

Rearrange the line equation of 5x - 2y + 6 = 0

So y = 5/2x +3

The y-intercept of the line equation is 3 as when x=0, y=3.

We know the Circle has the formula (x-4)^2 + (y-5)^2 = ?^2 from the question but with the intercept, we can find the entire equation as the y-intercept is (0,3) so we can substitute it into the equation to find the full equations so:

(0-4)^2 + (3-5)^2 = ?^2

This simplifies to:

(-4)^2 +(-2)^2 = ?^2

16 + 4 = 20 = ?^2

The answer is 20 so the equation of the circle is (x-4)^2 + (y-5)^2 = 20

The given value below figure find the value of x
tino4ka555 [31]

Answer:

<h2>x = 117°</h2>

Step-by-step explanation:

We know:

The sum of the quadrilateral angles measures 360°.

Therefore we have the equation:

30^o+39^o+48^o+m\angle D=360^o\qquad(1)

The sum of angles x and D is equal to 360°. Therefore we have the other equation:

x+m\angle D=360^o\qquad(2)

From (1) and (2) we have:

x+m\angle D=30^o+39^o+48^o+m\angle D\qquad\text{subtract}\ m\angle D\ \text{from both sides}\\\\x=30^o+39^o+48^o\\\\x=117^o
