Write the standard equation for the circle whose center is at ​(6​,2​) and whose radius is 2.
Grace [21]

Answer:

(x - 6)^2 + (y - 2)^2 = 2^2.

Step-by-step explanation:

In general, let (a,\, b) denote the center of a given circle. Let r denote the radius of that circle. The standard equation for that circle would be:

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

The circle in this question is centered at (6,\, 2).  

  • 6 is the x-coordinate of the center of this circle. a = 6.
  • 2 is the y-coordinate of the center of this circle. b = 2.

The radius of this circle is 2. Therefore, r = 2.

Hence, the standard equation for this circle would be:

(x - 6)^2 + (y - 2)^2 = 2^2.

Could someone please help me with this
Yuri [45]

Hey there!

Part A: 6,300 kilograms converted to grams would be 6,300,000. Right this into standard form would be the following:

6.3×10^2= 6,300,000

Part B: We do 7×10^-^5 = 0.00007

0.00007 × 6,3000 = 0.441

0.441 converted to standard notation would be the following:

4.41×10^-^1

Hope this answers your question!

Determine which package of balls has the most volume one bowling ball one basketball four dozen gold balls or 50 softballs
Yanka [14]

Answer:

50 softballs

Step-by-step explanation:

We will review case by case, to find out which one has less volume.

- One bowling ball, one ball, discarded.

- One basketball, one ball, discarded.

- Four dozen golf balls, a dozen are 12 and how are 4 dozen, would be 48 (12 * 4) there are two less than the balls than softballs, in addition to the fact that they give us the diameter in inches, the diameter always it is smaller than the circumference.

- 50 softballs, the largest number of balls, therefore the largest volume, in addition to the volume of each one is greater because they speak of circumference therefore it is greater than those that speak of diameter, that is, softball is more bigger than golf balls.
