The equation of a circle whose center is (3,7) and whose radius is 6 is
Aleks [24]
The equation of any given circle is:
{(x - h)}^{2}  +  {(y - k)}^{2}  =  {r}^{2}
where (h, k) is the center and r is the radius.

In the problem, we are given the center, and the radius. When we plug them in:
{(x - 3)}^{2}  +  {(y - 7)}^{2}  = 36
we got the formula of the circle.

Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using mathematical evidence or visual models.
d1i1m1o1n [39]

15% of 25 is the greatest of the two.

Answer:

25% of 15 is 3.75

15% of 25 is also 3.75

15 - 3.75 = 11.25

25 - 3.75 =21.25

Compare and then determine.

11.25 < 21.25

Ann believes that y= 3x (x -7) is a quadratic function. Jordan says that she is wrong because the degree (highest exponent) is n
ad-work [718]

Answer:

Ann us correct. It's a quadratic function.

Step-by-step explanation:

Given equation is,

y = 3x(x - 7)

By converting this equation into the standard quadratic equation,

y = 3x² - 21x

Highest exponent of the polynomial equation is 2 (Exponent of highest degree variable x²). This decides that the given function is a quadratic function.

Therefore, Ann is correct. It's a quadratic function.
