Hi there! :)

Answer:

y = 8.

Step-by-step explanation:

Starting with:

3/4y - 2 = 6 - 1/4y

Isolate the y variable to solve this equation. Begin by adding '1/4y' to both sides:

3/4y + 1/4y - 2 = 6

y - 2 = 6

Add 2 to both sides:

y = 8.

Answer:

$\large\boxed{Surface\ Area=63\ cm^2}$

Step-by-step explanation:

We have

square with sides s = 3cm

four triangles with base b = 3cm and height h = 9cm.

The formula of an area of a square:

$A_\square=s^2$

The formula of an area of a triangle:

$A_\triangle=\dfrac{bh}{2}$

Substitute:

$A_\square=3^2=9\ cm^2\\\\A_\triangle=\dfrac{(3)(9)}{2}=\dfrac{27}{2}=13.5\ cm^2$

The Surface Area:

$S.A.=A_\square+4A_\triangle\\\\S.A.=9+4(13.5)=9+54=63\ cm^2$

Rewrite the expression with a rational exponent as a radical expression.

Nuetrik [128]

Answer:

Rewriting the expression $(3^\frac{2}{3})^\frac{1}{6}$ with a rational exponent as a radical expression we get $\mathbf{\sqrt[9]{3} }$

Step-by-step explanation:

We need to rewrite the expression $(3^\frac{2}{3})^\frac{1}{6}$ with a rational exponent as a radical expression.

The expression given is:

$(3^\frac{2}{3})^\frac{1}{6}$

First we will simply the expression using exponent rule $(a^m)^n=a^{mn}$

$(3^\frac{2}{3})^\frac{1}{6}\\=(3^\frac{2}{18})$

As we know 2 and 18 are both divisible by 2, we can write

$=(3^\frac{1}{9})$

Now we know that $a^\frac{1}{9}=\sqrt[9]{a}$

Using this we get

$=\sqrt[9]{3}$

So, rewriting the expression $(3^\frac{2}{3})^\frac{1}{6}$ with a rational exponent as a radical expression we get $\mathbf{\sqrt[9]{3} }$

All points on a parabola are equidistant from the parabola's focus and the parabola's directrix. The _____ is the point on the p

Ipatiy [6.2K]

Answer:

The vertex is the point on the parabola where these distances are the smallest.

Step-by-step explanation:

All points on a parabola are equidistant from the parabola's focus and the parabola's directrix.

Now, the vertex is the point on the parabola where these distances are the smallest.

This is because if we draw a straight line through the vertex and the focus then it will be the axis of the parabola and axis of parabola is perpendicular to the directrix of the parabola and we know that the perpendicular distance of a point from a line is the minimum distance. (Answer)
