Kevin is going to purchase sod for his backyard (see diagram below). How many square feet of sod will Kevin need?

Answers

Answer:

450 square feet

Step-by-step explanation:

Think of the shape as a complete rectangular

The area of the rectangular shape would be 25×30 = 750 square feet

Now find the area of the missing space and subtract it from 750

it would be 15×20 = 300 square feet

750 - 300 = 450 square feet

If the length of an arc is 12 inches and the radius of the circle is 10 inches, what is the measure of the arc?I don't get this, keep getting it wrong. Can someone lead me through it???? PLZ

Answers

Assuming you are working in radians, the length of a circular arc is given by the definition of te radian:

s =r\theta which can be re-arranged to \theta = (s)/(r)

Using supplied known values:
\theta = (12)/(10) = 1.2 radians

If √6 is the geometric mean between 4 and another number, then the number is

Answers

If you have two numbers x, y.  The geometric mean is:  √xy

For 4 and x.  Geometric Mean =  √4x  and this is equal to √6

             √4x  =  √6     Square both sides.  The square root disappears.

               4x = 6 
                 x  = 6/4 = 3/2 = 1.5

The other number is 1.5.

 

Which statement could be used to explain why f(x)=2x-3 has an inverse relation that is a function

Answers

The correct answer is:

The function is a one-to-one function.

Explanation:

When an equation is graphed, we use the Vertical Line Test to determine if that equation is a function; if a vertical line hits more than one point anywhere on the graph, the graph is not a function.

This corresponds with the definition of a function:  A function is a set of ordered pairs in which each element of the domain (x) is mapped to no more than one element of the range (y).  Since every x has no more than one y, there will be no two points hit by the same vertical line.

When we have the graph of a function, to determine if it has an inverse, we use the Horizontal Line Test: if a horizontal line hits more than one point anywhere on the graph, the function does not have an inverse.

This corresponds with the definition of a one-to-one function:  A function in which every element of the range (y) is mapped to exactly one element of the domain (x). Since every y has one x, there will be no horizontal line that hits more than one point anywhere on the graph.
An inverse function is the relation formed when the independent variable is exchanged with the dependent variable in a given relation. To find this you just have to swap the x and y coordinates. The statement that could be used in this problem to explain why f(x) = 2x - 3 has an inverse relation that is a function is: B) f(x) is a one to one function.

I hope it helps, Regards.
