Can anybody help me with this? Use this graph of f to find the solutions to f(x) = 0.

Another way to say f(x) is y, so y=0 at -2 and 10. :)

Here is a diagram of a black circle inside a white square and a diagram of a small grey square inside a white square.

nika2105 [10]

The ratio of the area of the black circle to the area of the white square to the area of the gray square is π : 4 : 2

<h3>How to determine the ratio of the areas?</h3>

The side length AB is given as:

AB = 8x

The area of the white square is calculated as

White = (AB)²

This gives

White = (8x)²

Evaluate

White = 64x²

The side length AB represents the diameter of the black circle.

So, the radius is:

r =AB/2

This gives

r = 8x/2 = 4x

The area is then calculated as:

Circle = πr²

This gives

Circle = π(4x)²

Evaluate

Circle = 16πx²

Next, calculate AW and AZ using:

AZ = AW = AB/2

Evaluate

AZ = AW = 8x/2 = 4x

Calculate WZ using the following Pythagoras theorem

WZ² = AW² + AZ²

This gives

WZ² = (4x)² + (4x)²

Evaluate

WZ² = 2(4x)²

Take the square root of both sides

WZ = 4x√2

The area of the gray square is:

Gray = WZ²

This gives

Gray = 2(4x)²

Evaluate

Gray = 32x²

At this point, the areas are:

White = 64x²
Circle = 16πx²
Gray = 32x²

The ratio is then represented as:

Ratio = Circle : White : Gray

This gives

Ratio = 16πx² : 64x² : 32x²

Divide through by 16x²

Ratio = π : 4 : 2

Hence, the ratio of the area of the black circle to the area of the white square to the area of the gray square is π : 4 : 2

2, 2 1/2, 1 1\2, 2 whats the next number in the series

DedPeter [7]

<h3>Answer: 1</h3>

Explanation:

The jump from 2 to 2&1/2 is an increase of 1/2

2 + 1/2 = 2 & 1/2

The jump from 2 & 1/2 to 1 & 1/2 is a decrease of 1

(2 & 1/2) - 1 = (2 - 1) & 1/2 = 1 & 1/2

The jump from 1 & 1/2 to 2 is an increase of 1/2

(1 & 1/2) + 1/2 = 1 + (1/2 + 1/2) = 1 + 1 = 2

The pattern seems to be "add 1/2, subtract 1". Assuming this is the case, we would then subtract 1 from the last term we got (2) to get 2-1 = 1

PLZ HELP ill GIVE BRAINIESt!!!!20 Points

shepuryov [24]

She made her mistake at the first step. To simplify a radical, you would find two numbers that multiply by each other to get your original number (under the radical) and have one of the number be a perfect square.

Her reasoning is wrong because 10*10 is not $\sqrt{50}$ . Had she been correct, her answer should have been able to be squared to equal $\sqrt{50}$

In other words, she should have done $\sqrt{25*2}= \sqrt{25} * \sqrt{2}=5 \sqrt{2}$
(We used 25 because 25 is a perfect square, 5*5=25).
