Well the vertex is the highest or possibly lowest point in a quadratic equation, the part where it hits the curve. For example imagine this is your graph--> ∩.
This graph has its vertex at the top. So when we complete the square and find the zeroes we can then find where the graph meets in the middle thus finding our vertex.

At total of 2 feet of snow falls over three days on the first day 1/6 of the snow falls on the second day 7/12 of the snow falls
ioda

Answer:

Day\ 3 = 1\frac{3}{12}

Step-by-step explanation:

Given

Total = 2ft

Day\ 1 = \frac{1}{6}

Day\ 2 = \frac{7}{12}

Required

Determine the amount of snow on day 3

This can be calculated using:

Day\ 1 + Day\ 2 + Day\ 3 = Total

Substitute values for the known parameters

\frac{1}{6} + \frac{7}{12} + Day\ 3 = 2

Collect Like Terms

Day\ 3 = 2 - \frac{1}{6} - \frac{7}{12}

Take LCM

Day\ 3 = \frac{24 - 2 - 7}{12}

Day\ 3 = \frac{15}{12}

Express as mixed number

Day\ 3 = 1\frac{3}{12}

What is the area of triangle AED?
Ber [7]

Answer:

Then, the area of the right angle triangle AED is 84in^2.

Step-by-step explanation:

The triangle AED is a right angle triangle

And the area of a triangle is given as

Area=1/2base ×height

The base is 14in

And the height is 12in

Then,

Area=1/2base ×height

Area = 1/2 ×14 ×12

Area = 84in^2

Then, the area of the right angle triangle AED is 84in^2.
