Answer:

a.No

b.-7/2, it is at (4,-7/2)

c.-5?4, it is at (2,-5/4)

d.All real numbers except 6

e.3

f.-1/2

Step-by-step explanation:

a. Plug it in! f(5)=((5)+3)/((5)-6)=-8, so no!

b. Plug it in! f(4)=((4)+3)/((4)-6)=-7/2

c. Plug it in! f(2)=((2)+3)/((2)-6)=-5/4

d. If it were to be 6, then it would be 3/0 which would be undefined.

d.f(-3)=((-3)+3)/((-3)-6))=0/8

f.f(0)=((0)+3)/((0)-6)=-1/2

Answer:

1

Step-by-step explanation:

Distance between x's (Δx)

0

This field is calculated automatically, you cannot change it's value manually.

Distance between y's (Δy)

1

d = √(Δy2 + Δx2) = √(12 + 02) = √1 = 1

Match the formula with the polygon.

kherson [118]

Step-by-step explanation:

Lets sort out the areas of the polygons to match the areas with the corresponding polygons.

1. Triangle

The formula of the area of the triangle will be:

$A\:=\:\frac{1}{2} \:\:b\:h$

where b is the base and h is the height of the given triangle

2. rhombus

The formula of the area of the rhombus will be:

$A\:=\:\frac{pq}{2}$

where p and q being the diagonals

3. Parallelogram

The formula of the area of the parallelogram will be:

$A = bh$

where b is the base and h is the height

4. square

The formula of the area of the square will be:

$A\:=\:s^2$

where s being the length if any side, as all sides are equal in square

5. trapezoid

The formula of the area of the trapezoid will be:

$A\:=\:\frac{1}{2}\:h\left(b1\:+\:b2\right)$

where h is the height and $b1$ and $b2$ being the bases.

6. regular polygon

The formula of the area of the regular polygon will be:

$A\:=\:\frac{\left(ap\right)}{2}$

where a is the apothem and p is the perimeter.

7. equilateral triangle

The formula of the area of an equilateral will be:

$A\:=\:1/4\:s^2\:sqrt\left(3\right)$

where s is the length of one side of the triangle

How many SQUARES can you find? How many RECTANGLES can you find? How many TRIANGLES can you find?

saul85 [17]

First assumption: you want to use all 12 squares in each rectangle.

Let’s assume the squares are 1 inch on a side (could be foot, or yard, or whatever, but 1 UNIT).

Now, a rectangle has a length and a width. 12 squares an inch on a side have a total area of 12 square inches. So, your rectangle will also be 12 square inches.

To get that, you could have a rectangle of the following dimensions:

1 X 12

2 X 6

3 X 4

That’s it. Three possible rectangles, using all 12 squares per rectangle.

Now, if you DON’T have to use all 12 squares in the rectangle, then you could make 6 rectangles, using 2 squares each, so each rectangle would be 1 X 2.
