Suppose the graph of y= x^2 translated left 2 units, and up 8 units

Elis [28]

Start with y = x2

Shift 2 units left to get y = (x+2)2

Vertically stretch to get y = 6(x+2)2

Reflect across x-axis to get y = -6(x+2)2

Shift 7 units down to get y = -6(x+2)2 - 7

hope this helps!

Find the circumference of this figure. Show your calculations.

solong [7]

Answer:

Circumference of circle= 37.68 units

Circumference of sector= 6.28 units

Step-by-step explanation:

The given figure is a circle with given radius OB= 6 units.

The circumference of a circle is the total length of its boundary.

For the complete circle its circumference can be calculated by;

Circumference= $2\pi r$

$=2*3.14*6\\=37.68$ units

For the circumference of the Sector with 60° in the figure, the circumference can be calculate by:

$=\frac{60}{360}* 2*\pi*6\\\\=\frac{1}{6}*12*3.14\\\\ =2*3.14\\\\=6.28$ units

So, the circumference of the full circle is 37.68 units and the circumference of the sector is 6.28 units.
