Which expression is equivalent to 6m+(m-2)(m+7)+3

Vika [28.1K]

Answer:

$m^{2}$ + 11m - 11

Step-by-step explanation:

6m+(m-2)(m+7)+3 = 6m + [ m*m - 14 -2m + 7m] + 3

= 6m + mm - 14 + 5m + 3

= mm + 11m - 11

6m+(m-2)(m+7)+3 = $m^{2}$ + 11m - 11

Write the following polar equation in Cartesian coordinates:

maks197457 [2]

Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)

Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))

Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
