Naddika [18.5K]

Answer:

The number of desktop internet users are 3 times more than the number of mobile internet users.

Step-by-step explanation:

We are given the following in the question:

Number of mobile internet users = 400,000,000

$400,000,000 = 4\times 10^{8}$

Number of desktop internet user =

$1.2 \times 10^9$

Comparison of values:

$=\dfrac{\text{Number of desktop internet user}}{\text{Number of mobile interet user}}\\\\=\dfrac{1.2\times 10^9}{4\times 10^8}\\\\=0.3\times 10\\=3$

Thus, the number of desktop internet users are 3 times more than the number of mobile internet users.

What is the equation of the circle with center (4, 4) that passes through the point (10, 14)?

Katarina [22]

Answer:

Step-by-step explanation:

You use the given information in the standard form of a circle equation to solve for r. We have (h, k) which is the center and a point (x, y). The standard equation for a circle is

$(x-h)^2+(y-k)^2=r^2$

Filling in:

$(10-4)^2+(14-4)^2=r^2$ and

$6^2+10^2=r^2$ and

$r^2=136$

Now that we used the coordinate we don't need it anymore. x and y go back into the equation as x and y, not numbers. We do, however, need the center. Writing the equation:

$(x-4)^2+(y-4)^2=136$ which is choice D.
