What is the area of the composite figure?
mars1129 [50]

Answer:

34.9^2

Step-by-step explanation:

Well if one side is 4 cm then the square is 16cm^2.

The area of a circle is pi r^2.

So the radius is 2.

we plug 2 in.

pi 4

12.6/2

6.3

6.3 * 3 = 18.9cm^2

18.9 + 16 = 34.9

Solve (x-3)^2 = 5 HELP ASAP!!! Please!! :(
Bas_tet [7]

Answer:

<em>Answer</em><em> </em><em>is</em><em> </em><em>option</em><em> </em><em>d</em><em> </em>

Step-by-step explanation:

given \: expression \: is \:  {(x - 3)}^{2}  = 5 \\  {x}^{2}  - 6x + 9 = 5 \\ subtracting \: 5 \: on \: both \: sides \: we \: get \\  {x}^{2}  - 6x + 4 = 0 \\ on \: solving \: the \: quadratic \: equation \: by \\  \: completing \: square \: method \\  {x}^{2}  - 6x =  - 4 \\ adding \:  {3}^{2} on \: both \: sides \: w e\: get \\  {x}^{2}  - 6x +  {3}^{2}  =  {3}^{2}  - 4 \\  {(x - 3)}^{2} = 5 \\ x - 3 + =    \sqrt{5}  \\ x =  \sqrt{5 }  + 3

Find the vector that has the same direction as 3, 2, −6 but has length 2.
Nata [24]

Answer:

The vector is \vec r = \left(\frac{6}{7},\frac{4}{7},-\frac{12}{7}\right).

Step-by-step explanation:

We can determine the equivalent vector (\vec r), dimensionless, by means of the following formula:

\vec r = \frac{\vec u}{\|\vec u\|} \cdot \|\vec r\| (1)

Where:

\vec u - Original vector, dimensionless.

\|\vec u\| - Norm of the original vector, dimensionless.

\|\vec r\| - Norm of the new vector, dimensionless.

The norm of the original vector is determined by the following definition:

\|\vec u\| = \sqrt{\vec u\,\bullet \,\vec u} (2)

If we know that \vec u = (3, 2, -6), then the norm of the original vector is:

\|\vec u\| = \sqrt{(3)\cdot (3)+(2)\cdot (2)+(-6)\cdot (-6)}

\|\vec u\| = 7

If we know that \|\vec r\| = 2, then the new vector is:

\vec r = \frac{2}{7}\cdot (3,2,-6)

\vec r = \left(\frac{6}{7},\frac{4}{7},-\frac{12}{7}\right)

The vector is \vec r = \left(\frac{6}{7},\frac{4}{7},-\frac{12}{7}\right).

If the diameter of a sphere is doubled, its surface becomes
hodyreva [135]
Volumes scale as the cube of a corresponding dimension. Therefore, if the radius of a sphere is doubled (r becomes 2r), the surface area becomes 2 squared, or 4 times the original surface area. The volume would become 2 cubed, or 8 times the original volume.
