Answer:

Take out the area of the full circle first:

A= pi r^2

A= 3^2 x pi

A= 28.274 cm3

Area of smaller cirlces:

A= pi r^2

A= 1^2 x pi

A= 3.14159

Multiply by 2 as 2 circles: 6.28318

Substract unshaded from shaded: 28.274-6.28318

Area of shaded is 21.99082 cm3

Find the values of x and y​
valentina_108 [34]

Answer:

x = 3, y = 1

Step-by-step explanation:

2 raised to what power gives you 16?

2*2*2*2 = 16 so 2^4

3 raised to what power gives you 9?

3*3 = 9 so 3^2

the exponent cannot be negative so x has to be greater than y and x cannot be the same as y otherwise you will get a 0.

x = 3 , y = 1

2^(3+1) = 2^4 = 16

3^(3-1) = 3^2 = 9

Simplify the radical expression.
tresset_1 [31]

To simplify this fraction, multiply the entire fraction by the conjugate of the denominator. The conjugate of a square root and a number being added to it would be the number <em>subtracted </em>from the square root. In other words, the conjugate of \sqrt{a} + b would be\sqrt{a} - b.


Applying that information to our fraction shown here, the conjugate of the denominator would be \sqrt{3} - 4. We will multiply both the numerator and denominator of our original fraction by this expression to obtain our answer, as shown below.


\Big(\dfrac{1}{\sqrt{3} + 4}\Big)\Big(\dfrac{\sqrt{3} - 4}{\sqrt{3} - 4}\Big)

\dfrac{\sqrt{3} - 4}{3 - 16}

\dfrac{4 - \sqrt{3}}{13}


Our answer is \boxed{\dfrac{4 - \sqrt{3}}{13}}.

please someone answer number 1 and number 3!! it would be much appreciated if you could make it sound like and 8th graders work.
Luda [366]

Almost all linear equations are functions but not all straight lines are a graph of a function.A linear function with its y-intercept as zero passes through the origin.

step-by-step explanation:

1. Linear means a graph that makes a straight line where as a function represents all set of values in (x,y) system on a graph where a single x point has a corresponding y point value.

A function can be linear to form a straight line or a curve in the case of nonlinear functions.

The similarity is observed where both the straight line and the function assume the shape of a straight line. In this case, they are both linear. However, a function can be a curve and not a straight line, thus the difference.

3. The origin (0,0) and the y-intercept can be found in a table of values for a certain function and appear on the graph and the equation of a function. For example in the function y=4x, a table of value of x and y can be;

x           y

-1          -4

0           0

1            4

2           8

Here you notice when x=0, y=0, this tells you that the y-intercept is 0. From the slope intercept form of a graph, y=mx+c , c is the y-intercept, and for our case, y=4x, the value of c=0 to mean the function passes through the origin (0,0). This is observed in the table where x=0, y=0, on the attached graph where the line passes through the origin and in the equation y=4x where the value of c=0
