There were seventeen thousand four hundred nine people at a baseball game. What is this number in expanded form?
padilas [110]

Hi!

<h3>Expanded form is when we multiply each of the digits by how many 0s they have. </h3>

So 253 is (2 x 100) + (5 x 10) + (3 x 1).

17,000

400

9

(<u>17 x 10,000) + (4 x 100) + (9 x 1)</u>

<h2>The answer is C) (<u>17 x 10,000) + (4 x 100) + (9 x 1)</u> (which equals 17,409)</h2>

Hope this helps! :)

Write the equation of the circle with center of 10-2 and a radius of 7
True [87]

Answer:

(x-10)^2 + (y-2)^2 = 49

Step-by-step explanation:

I'm assuming that 10-2 means (10,2)

Equation of circle:

(x-a)^2 + (y-b)^2 = r^2

Plugging in the values that we know:

(x-10)^2 + (y-2)^2 = 7^2

(x-10)^2 + (y-2)^2 = 49

Hope this helps!
