Find the coordinates of y-axis
zhenek [66]

Answer:

Find the coordinates of the point on the y-axis which is nearest to the point (-2, 5). Hint: Any general coordinates on y-axis can be written as (0, y), as the x-coordinate on y-axis is always zero. Use this along with the distance formula to get the nearest point to (-2, 5).

Which of these is an odd function?
Yakvenalex [24]

Answer:

f(x)=2x^3+x

Step-by-step explanation:

An odd function <em>f</em> is one where f(-x)=-f(x). We can interpret this is meaning: reflecting the graph horizontally f(-x) has the same effect as reflecting it vertically -f(x) . The only graphs that meet this requirement are ones with reflectional symmetry across the line y = x, so we can immediately elimate the functions f(x)=3x^2+7 and f(x)=5x^2-6, which have horizontal symmetry, but not the kind of symmetry we're looking for.

That leaves us with f(x)=2x^3+x and f(x)=4x^3+2x^2. One feature of exponents we can utilize is that -1 to an even power is 1, while -1 to an odd power is -1. If we want f(-x)=-f(x), we need to flip the signs of <em>all </em>the coefficients, and we can only do that if all the powers of x are odd. The only function with only odd powers of x is f(x)=2x^3+x, and plugging in -x to the function reveals that

f(-x)=2(-x)^3+(-x)\\f(-x)=-2x^3-x=-(2x^3+x)=-f(x)

So f(x)=2x^3+x the only odd function on the list!

Solve the equation. \dfrac34 =m+\dfrac14 4 3 ​ =m+ 4 1 ​ start fraction, 3, divided by, 4, end fraction, equals, m, plus, start
RSB [31]

Answer:

\boxed{\dfrac{1}{2} = m}

Step-by-step explanation:

Given equation:

\dfrac{3}{4} = m + \dfrac{1}{4}

<u>Step-1: Subtract 1/4 both sides</u>

\dfrac{3}{4} = m + \dfrac{1}{4}

\dfrac{3}{4} - \dfrac{1}{4} = m

\dfrac{2}{4}  = \boxed{\dfrac{1}{2} = m}
