For 7 and 8, find the maximum or minimum point of the parabola​
Leni [432]

Answer: 7) Max: y = 52

               8) Min: y = -51  

<u>Step-by-step explanation:</u>

The Max/Min is the y-value of the intercept.

  • Max is when the a-value is negative.
  • Min is when the a-value is positive.

First, find the x-value of the vertex using the Axis of Symmetry formula:

x = -b/2a. Then plug the x-value into the equation to find the y-value.

7) y = -2x² - 16x + 20

          ↓       ↓       ↓

     a= -2   b= -16  c=20

\text{AOS:}\quad x=\dfrac{-b}{2a}\quad =\dfrac{-(-16)}{2(-2)}\quad =\dfrac{16}{-4}\quad =-4

Max: y = -2(-4)² - 16(-4) + 20

           = -2(16) + 64 + 20

           = -32 + 84

          = 52

*********************************************************************************************

7) y = x² + 12x - 15

        ↓      ↓      ↓

   a= 1   b= 12  c= -15

\text{AOS:}\quad x=\dfrac{-b}{2a}\quad =\dfrac{-(12)}{2(1)}\quad =\dfrac{-12}{2}\quad =-6

Max: y = (-6)² + 12(-6) - 15

           = 36 - 72 - 15

           = 36 - 87

          = -51

Cesar is making a model of the Eiffel Tower. The height of the tower is 984 feet, and Cesar wants to make a 1.5-foot
n200080 [17]

Answer:

See below

Step-by-step explanation:

First, lets see how many feet of the original Eiffel tower (O) are represented in 1 foot of Caesar's tower model (M). We know that 1.5 foot is equal to 984 feet of the original, so we can say:

1.5 M = 984 O, this is our equivalence.

Now divide both sides by 1.5

1.5 M / 1.5 = 984 O / 1.5

1 M = 656 O

So, 1 foot of Cesar's Model is 684 feet of the original tower. We also know that 1 foot is equal to 12 inches, so we can say that 12 inches of Cesar Model (12 m) are equivalent to 656 feet of the original tower. So:

12 m = 656 O

If we divide both sides by 12:

m = 656/12 O

m = 56.67

So, 1 inch in Cesar's model represent 56.67 feet of the original Eiffel Tower.

Lets verify our result by multiplying 56.67 by 12 to get 1 feet and then by 1.5 to get the measure of the model:

56.67*12*1.5 = 984 feet, which is the height of the Eiffel tower.

Scale: 1 inch = 56.67 feet
