1^81 is 1 multiplied by itself 81 times, which equals 1

3^4 is 3 multiplied by itself 4 times (3 x 3 x 3 x 3), which equals 81

6^4 is 6 multiplied by itself 4 times (6 x 6 x 6 x 6), which is 1296

9^2 is 9 multiplied by itself twice (9 x 9), which is 81

27^3 is 27 multiplied by itself 3 times (27 x 27 x 27), which is 19683.

Y+4=1/2(x−2) rewrite in slope intercept form<br><br>1/2 is a fraction

Trava [24]

Answer:

y= 1/2x -5

Step-by-step explanation:

First, you multiply 1/2 with x, and 1/2 with -2, which then makes the equation

y+4=1/2x -1

then, you have to subtract 4 from both sides of the equation and combine -1 and -4, which gets you -5.

Then the equation turns out to be

y=1/2x-5

Find the formula for the area of the shaded region in the figure.<br> x² = 4py<br> ہے

Alexandra [31]

The formula for the area of the shaded region in the figure.

x² = 4py is mathematically given as

$A=\frac{8}{3} \sqrt{p h} \cdot h$

<h3>What is the formula for the area of the shaded region in the figure?</h3>

Parameters

$x^{2}=4 p y$

$y=h$

$\therefore x^{2}=4 p h \Rightarrow x=2 \sqrt{p h} \\$

Generally, the equation for the Area is mathematically given as

$& A=2 \int_{0}^{2 \sqrt{p h}}\left(h-\frac{x^{2}}{4 p}\right) d x \\\\& A=2\left(h x-\frac{x^{3}}{12 p}\right]_{0}^{2 \sqrt{p h}} \\\\& A=2\left[\left[h 2 \sqrt{p h}-\frac{1}{12 p} \cdot(2 \sqrt{p h})^{3}-0\right]\right. \\$

$&A=2\left[2 h^{3 / 2} \sqrt{p}-\frac{8(\sqrt{p})^{3}(\sqrt{h})^{3}}{12 p}-0\right] \\\\&A=2\left[2 h^{k / 2} \sqrt{p}-\frac{2}{3} \sqrt{p} \cdot h^{3 / 2}\right] \\\\&A=2 \times \frac{4 \sqrt{p} \cdot h^{3 / 2}}{3} \\\\&A=\frac{8}{3} \cdot \sqrt{p} \cdot \sqrt{h} \cdot h \\\\&A=\frac{8}{3} \sqrt{p h} \cdot h$
