~Hello There!~

Step A:

Divide 120 by 3:

120/3 = 40

$40 is 1/3 of the original price

However, the question says that it was marked down by 1/3, therefore, you must subtract 40 from 120 to get the answer:

120 - 40 = 80

In short, the answer is $80.

Step B:

Divide 80 by 2:

80/2 = 40

$40 is 1/2 of the sales price

The question states that it was marked up by this amount, therefore, you must add it onto 80:

80 + 40 = 120

In short, the answer is $120.

Hope This Helps You!                                                            

Good Luck :)                                                                                  

Have A Great Day ^_^

What are the coordinates of the focus of the conic section shown below?
Aleksandr [31]
The answer is 
y^2-4x+4y-4=y^2+4y-4x-4=(y+2)²-4x - 8= 0
it is the same of    x + 2 = (1/4 ) (y+2)²
   
the main formula is  x-h= a (y-k)² so h=-2, k= - 2 and a=1/4

Answer:

We get t= 7.22 and t=0.28

The correct options are Option A and Option G

Step-by-step explanation:

The height h of toy rocket at time t seconds after  launch is given by the equation h(t) = -16t^2 + 120t + 8

We need to find how many seconds  until the rocket is 40 feet?

We are given height of rocket h(t) = 40 feet

and we need to find time t

Using the equation h(t) = -16t^2 + 120t + 8 we can find time t

We have h(t)=40

h(t) = -16t^2 + 120t + 8\\Put\:h(t)=40\\40= -16t^2 + 120t + 8\\16t^2-120t-8+40=0\\16t^2-120t+32=0

Now, we will solve the quadratic equation using quadratic formula: t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

We have a =16, b=-120 and c=32

Putting values and finding t

t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\frac{-(-120)\pm\sqrt{(-120)^2-4(16)(32)}}{2(16)}\\t=\frac{120\pm\sqrt{14400-2048}}{32}\\t=\frac{120\pm\sqrt{12352}}{32}\\t=\frac{120\pm111.12}{32}\\t=\frac{120+111.12}{32}, t=\frac{120-111.12}{32}\\t=7.22\:,\:t=0.28

So, we get t= 7.22 and t=0.28

The correct options are Option A and Option G
