Adam wants to buy a video game system that costs $100.00. He has $28.35 in one piggy bank and $31.90 in another piggy bank. How much more money does Adam need before he can buy the video game system? How can estimation be used to make sure the answer is reasonable?

A.
Answer: Adam needs $160.25 more.
Estimation: $28 + $32 = $60.
$100 + $60 = $160.
Adam needs about $160 more to buy his video game system.

B.
Answer: Adam needs $39.75 more.
Estimation: $28 + $32 = $60.
$100 – $60 = $40.
Adam needs about $40 more to buy his video game system.

C.
Answer: Adam needs $30.13 more.
Estimation: $28 + $32 = $60.
$60 ÷ 2 = $30.
Adam needs about $30 more to buy his video game system.

Answers

Since we want to know how much more he needs out of the total, we must do subtraction. Since the only subtraction one is C, The answer is C.

Find all the zeros of the equation-3x^4+27^2+1200=0
if you could show yourworkthat would be great :3

Answers

Divide both sides by -3, and replace $x^2$ with $y$ . Then

$-3x^4+27x^2+1200=0\iff y^2-9y-400=0$

Factorize the quadratic in $y$ to get

$y^2-9y-400=(y+16)(y-25)=0\implies y=-16,y=25$

which in turn means

$x^2=-16,x^2=25$

But $x^2\ge0$ for all real $x$ , so we can ignore the first solution. This leaves us with

$x^2=25\implies x=\pm√(25)=\pm5$

If we allow for any complex solution, then we can continue with the solution we ignored:

$x^2=-16\implies x=\pm√(-16)=\pm i√(16)=\pm4i$

How do you make a parabola?

Answers

Make an equation where

Y =

The graph of that equation is guaranteed to be a parabola.
