Mathematics
1 answer:
kipiarov [429]3 years ago
6 0

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

Change the width 20/16 inches to a mixed numeral in simplest form.
Iteru [2.4K]

Answer:1 and 1/4


Step-by-step explanation:

Okay, let's see the given: 20/16

So, we can take out 16 from the top to make it 1  4/16

Now, we can simplify that by dividing the top and bottom by 2: 1  2/8

We can simplify that again to get 1 1/4

So the answer is 1 and 1/4

Use the rules of exponents to evaluate or simplify. Write without negative exponents. 1/4^-1/2 = ___ a0
Nastasia [14]

For this case we have, by definition:


a^{-b} =\frac{1}{a ^ b}

So, we have:


\frac{1}{4}^{-\frac{1}{2}}=\frac{1}{(\frac{1}{4})^{\frac{1}{2}}}

On the other hand we have that by definition:


a^{\frac{1}{2}}=\sqrt{a}

Thus, the expression can be written as:


\frac{1}{\sqrt {\frac{1}{4}}} =

\frac{1}{\frac{1}{\sqrt{4}}}

\frac{1}{\frac{1}{2}}

\frac{1*2}{1*1}=2

So, we have:


\frac{1}{4}^{-\frac{1}{2}}= 2

Answer:


\frac{1}{4}^{-\frac{1}{2}}= 2

If triangle RST and triangle XYZ are similar, which of these equations must be true?
Delicious77 [7]

Answer: A

Step-by-step explanation:

If they are similar, that means the proportions for corresponding sides will be the same.

          I personally ignore the picture and use the labels of "triangle RST and triangle XYZ" that the problem gives <em>because</em> the XYZ picture is not lined up with the similarity it has with RST.

(A) says that side ST is corresponding with side YZ,

          [] Triangle R<u>ST</u> and triangle X<u>YZ</u>

          -> Correct

(A) also says that side RT is corresponding with size XZ,

          [] Triangle <u>R</u>S<u>T</u> and triangle <u>X</u>Y<u>Z</u>

          -> Correct

               This means that option A is the correct answer.
