<span>In the given set, {(-1,1/2),(-1/2,-1),(3/2,0),(2,3/2)}, the x-values are the values that will be a part of the domain i.e. domain will be {-1,-1/2, 3/2 ,2 } and the range will be {1/2, -1,0, 3/2}. Thus, the values of domain is the x-coordinate and range is the y-coordinate</span>

we know that

A mapping diagram shows how the elements are paired. Its like a flow chart for a function, showing the input and output values.The input values are the elements of the domain and the output values are the elements of the range.

In this problem

Input Values (Domain) are

[-1, -1/2, 3/2,2]

Output Values (Range) are

[1/2, -1,0,3/2]

therefore

The answer is

Part a) The graph see the attached figure

Part b) Input Values (Domain) are [-1, -1/2, 3/2,2]

Part c) Output Values (Range) are [1/2, -1,0,3/2]

Answer:

  (5/2)√13 ≈ 9.0139

Step-by-step explanation:

The longer hypotenuse is found using the Pythagorean theorem as ...

  \sqrt{8^2+12^2}=\sqrt{208}=4\sqrt{13}

The right triangles are AA similar, and vertical sides correspond. Their ratio, smaller/larger is 5/8. That means the hypotenuse of the smaller triangle, A, is 5/8 of the hypotenuse of the larger one.

  A=\dfrac{5}{8}\cdot 4\sqrt{13}= \dfrac{5\sqrt{13}}{2}

Answer:

8.49\ units

Step-by-step explanation:

we know that

The Pythagorean Theorem states that in a right triangle

c^2=a^2+b^2

where

c is the greater side (the hypotenuse)

a and b are the legs

In this problem

Let

c=AB ---> distance from point A to point B

a ---> the difference of the x-coordinates both points

b ---> the difference of the y-coordinates both points

so

a=1-(-5)=6\ units\\b=6-0=6\ units

substitute

AB^2=6^2+6^2

AB^2=72

AB=\sqrt{72}\ units

AB=8.49\ units

The flagpole at school casts a shadow that is 18 feet long. A student nearby is 5.5 feet tall and casts a shadow that is 3 feet
azamat

Answer:

33 feet.

Step-by-step explanation:

If the ratio of the student to their shadow and flagpole to its shadow are equal, then you can use the proportion

5.5/3 = x/18 and cross multiply to find x.

5.5 × 18 = 99

3 × x = 3x

3x/3 = x, 99/3 = 33.

x = 33.
