Answer:

40%

[img id="5156800"][/img]

Step-by-step explanation:

Image description: A pie that is split into 5 pieces, similar to the rectangle in the question, except no region is shaded.

1. You see that there are 5 quadrants in the rectangle.

2. You count how many quadrants of the rectangle are shaded in.

3. In the following image there are two shaded quadrants which means 2 out of the 5 quadrants are shaded.

4. In fractions this would equate to 2/5, but this question is asking for percantages.

5. Most of the time percantages are out of 100%, so that is what we'll be basing our answer off of.

6. First we can start with the totoal amount of quadrants, which is 5, and we will divide the 100% by 5, which is 20%.

7. Because there are two shaded areas we would equate each shaded quadrant to 20%, and because there are 2 shaded quadrants we would multiply the number of shaded quadrants by 20%.

8. So we would get 20x2=40

9. By these calculations we would get 40%

10. 40% of the rectangle is shaded.

Answer:

40%

Step-by-step explanation:

The whole rectangle is split into 5 parts. Two out of 5 parts are shaded.

Set up a fraction:

\frac{\text{Shaded}}{\text{Whole}}=\frac{2}{5}

Convert into a decimal:

\frac{2}{5}= 0.4

Multiply the decimal by 100 to get the percent:

0.4*100=40

So, forty percent of the rectangle is shaded.

Hope this helps.

What does the quadratic function f(x)=x^2-10x+9 look like when it is rewritten in the form f(x) = a (x-h) + k
Tatiana [17]

ANSWER

When f(x)=x^2-10x+9 is written in the form f(x)=a(x-h)^2+k, it looks like f(x)=(x-5)^2-16


EXPLANATION

To write  f(x)=x^2-10x+9 in the form f(x)=a(x-h)^2+k, we have to complete the squares.


We add and subtract half the coefficient of x square.


f(x)=x^2-10x+(-5)^2-(-5)^2+9


The first three terms of the function is now a perfect square.

f(x)=(x-5)^2-25+9

We now simplify rto obtain,

\Rightarrow f(x)=(x-5)^2-16
