How to Find the vertex of f(x)=-8x^2-8x+7
charle [14.2K]

Answer:

The answer to your question is: (1/2, 5)

Step-by-step explanation:

Parabola                     f(x) = 8x² - 8x + 7

                                     y = 8x² - 8x + 7

Vertical Parabola equation

( x - h)² = 4p (y - k)            Transform the original equation to this form

8x² - 8x       = y - 7            

8(x² - x  + (   )²)  = y - 7       Complete squares

8 (x² - x + (1/2)²) = y - 7 + 2    Simplification

8 (x² - x + 1/4) = y - 5

                                 (x - 1/2)² = 1/8 (y - 5)

Finally Vertex

                        (1/2 , 5)

A hemispherical bowl with a 30-centimeter radius contains some water, which is 12 centimeters deep. Find the volume of the water
Anon25 [30]

Answer:

The volume of the water is 56520 cubic cm

Step-by-step explanation:

Radius of hemispherical bowl = 30 cm

Depth of water in bowl = 12 cm

Volume of hemispherical bowl = \frac{2}{3} \pi r^3

Volume of hemispherical bowl = \frac{2}{3} \times 3.14 \times 30^3

Volume of hemispherical bowl = 56520 cm^3

So, there is 56520 cubic cm water in hemispherical bowl

Hence the volume of the water is 56520 cubic cm

For a wedding, a pastry chef is increasing the cake recipe by 4 and ½ times. How much butter is needed? Flour?
BaLLatris [955]

Answer:

Butter: 18/4 cups

Flour: 36 cups

Step-by-step explanation: I think this is right.

4 1/2 = 9/2

9/2 x 1/4 = 18/4 x 1/4 = 18/4

1 1/3 = 4/3

9/2 x 4/3 =  27/6 x 8/6 = 216/6 = 36
