HELP PLEASE

Gnesinka [82]

Answer: $x^2=8y$

Step-by-step explanation:

Let the given parabolic mirror opens upwards and vertex=(0,0)

Focus point of the parabolic mirror is located 2 inches from the vertex of the mirror. ∴ p=2

Since, the parabola opens upward, then the equation of the parabola is of the form $x^2=4py$

Substitute the value of p=2 in this, we get the equation of the parabolic mirror

$x^2=4(2)y\\\Rightarrow\ x^2=8y$

Hence, the equation of the parabola that models the cross section of the mirror is $x^2=8y$

Leto [7]

Hey there!

(3x)^2 - 2x^2

= (3(-2))^2 - 2(-2)^2

= -6^2 - 2(4)

= 36 - 8

= 28

Therefore, your answer is: 28

Good luck on your assignment and enjoy your day!
