Answer:

Vertex form

Step-by-step explanation:

You convert to  vertex form  a(x - b)^2 + c . The coordinates of the maxm/minm will be (b, c).

For example find minimum value of  x^2 + 5x - 6:-

x^2 + 5x - 6

=  (x + 2.5)^2 - 6.25 - 6

= (x + 2.5)^2 - 12.25

The coordinates of minimumm will be (-2.5, -12.25)  The values of the minimum of the function is -12.25

The school lunch prices are changing next year. The cost of a hot lunch will increase $0.45
dolphi86 [110]

Answer:

$2.60- $0.45= $2.25 (Two dollars and 25 cents per one hot lunch is the cost of this year's lunch)

Step-by-step explanation:

To solve this word problem, first pin point what the question is asking.

The question wants you to determine the price of a hot lunch this school year.

The price of a hot lunch after the 45 cent raise will be $2.60.

So, based on this info, to solve the word problem you must take away the 45cent raise. $2.60- $0.45 = $2.25

To check if this answer is correct, add 45 cents to the this year cost($2.25) If you get $2.60, then your answer is correct.

What is the monomial if a square of a monomial is: 1/4 a2n
lilavasa [31]

Answer:

\frac{1}{2} a^n

Step-by-step explanation:

Square of the monomial is \frac{1}{4}a^{2n}

To get the monomial we take square root

Lets take square root for each term

\sqrt{\frac{1}{4}a^{2n}}

\sqrt{\frac{1}{4}}=\fract{1}{2} because square root of 4 is 2

\sqrt{a^{2n}}=(a^{2n})^\frac{1}{2}

2/2 is 1 so, its a^n

Required monomial is  \frac{1}{2} a^n
