A circle is centered at (0,0) and has a radius of 2\sqrt{3}
VikaD [51]

Answer:

Outside of the circle

Step-by-step explanation:

First, find the equation of the circle by plugging in the center point and radius:

(x - h)² + (y - k)² = r²

(x - 0)² + (y - 0)² = (2\sqrt{3})²

x² + y² = 12

Plug in point M to see where it lies:

x² + y² = 12

(-3)² + (2)² = 12

9 + 4 = 12

13 ≠ 12

Since this statement is false, point M lies outside of the circle.

What is the answer (7t2+4t+1)–4t2
Solnce55 [7]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{3 {t}^{2}  + 4t + 1}}}}}

Step-by-step explanation:

\sf{ (7 {t}^{2}  + 4t + 1) - 4 {t}^{2} }

Remove the unnecessary parentheses

\longrightarrow{ \sf{7 {t}^{2}  + 4t + 1  - 4 {t}^{2} }}

Collect like terms

\longrightarrow{ \sf{7 {t}^{2}  - 4 {t}^{2}  + 4t + 1}}

\longrightarrow{ \sf{3 {t}^{2}  + 4t + 1}}

Hope I helped!

Best regards! :D
