Perform the indicated operation. (12x2 + 7y3)(4x2 + 7y3)

Verdich [7]

ANSWER

$48 {x}^{4} + 60{x}^{2} {y}^{3} + 56 {y}^{6}$

EXPLANATION

We want expand:

$(12x^2+8y^3)(4x^2+7y^3)$

We expand using the distributive to obtain:

$12 {x}^{2} (4 {x}^{2} + 7 {y}^{3} ) + 8 {y}^{3} (4 {x}^{2} + 7 {y}^{3} )$

$48 {x}^{4} + 28 {x}^{2} {y}^{3} + 32{x}^{2} {y}^{3} + 56 {y}^{6}$

Simplify further by combining the two terms in the middle:

$48 {x}^{4} + 60{x}^{2} {y}^{3} + 56 {y}^{6}$

Find an equation of the circle that has center (-4,3) and passes through (6,-4).

kumpel [21]

Answer:

$(x+4)^2+(y-3)^2=149$

Step-by-step explanation:

The equation of a circle is $(x-h)^2+(y-k)^2=r^2$ where $(h,k)$ is the center of the circle and $r$ is the radius of the circle.

Given that $(h,k)\rightarrow(-4,3)$ and it passes $(6,-4)$ , their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:
