Choose the correct conic section to fit the equation.

yanalaym [24]

Answer:

Option A) Circle.

Step-by-step explanation:

We are given the equation:

$(x - 3)^2 + (y - 12)^2 = 25$

A general equation of the circle is of the form:

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

where (h,k) is the center of the circle and r is the radius of circle.

Comparing the two equations, we get,

$(h,k) = (3,12)\\r = \sqrt{25} = 5$

Thus, the given equation is equation of a circle centered at (3,12) and of radius 5 units.

Answer:

-11.5

Step-by-step explanation:

$K + n( {p}^{2} ) \\ \\ plug \: K = 0.5, \: n = - 3, \: p = - 2 \\ \\ K + n( {p}^{2} ) \\ \\ = 0.5 + ( - 3) \{ {( - 2)}^{2} \} \\ \\ = 0.5 - 3 \{ 4 \} \\ \\ = 0.5 - 12 \\ \\ = - 11.5$

yarga [219]

4 x 0.90 = £3.60
£13.50 - £3.60 = £9.90
0.9 + 0.75 = £1.65
£9.90/£1.65 = 6
They bought 6 ice cream cones
