Hello :

the common ratio is m 20/100=0.8/4=1/5 = 0.2= r

the nth term is : An =A1 × r^(n-1)

if n=5 the 5th term is : A5 = 100×(0.2)^(5-1) = 100×0.16 =16

the common ratio is m 20/100=0.8/4=1/5 = 0.2= r

the nth term is : An =A1 × r^(n-1)

if n=5 the 5th term is : A5 = 100×(0.2)^(5-1) = 100×0.16 =16

Angles 1, 3, 5, 7, 9 and 11 are corresponding while angles 2, 4, 6, 8, 10 and 12 are corresponding

angles 8 and 7 are supplementary

since 4 and 8 are corresponding, angle 4 is 132° so angle 8 would also be 132°

180-132=48°

angle 7 would be 48°

If A(x', y') & B(x",y") the the distance AB is given by the following formula:

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

Let x be the number of songs downloaded.

Each song is $1.29; the total cost would be found by multiplying the cost by the number of songs, or 1.29x.

This cannot be more than 20, so we set this less than or equal to 20:

1.29x ≤ 20.

__To solve this, we divide both sides by 1.29: __

In a right triangle, the hypotenuse is always the longest side. Plus, the hypotenuse squared has to equal the sum of the squares of the other 2 sides. For the first "triangle" above: does ? Let's check. 196 = 25 + 16 so does 196 = 41? Obviously not. So that is not a right triangle. Let's check the second one the same way. Does ? 25 = 9 + 16. Does 25 = 25? Of course it does! So 1 is not a right triangle, but 2 is!

Choice A. Work done below:

4x-1=5x-8 ( Set the opposite sides equal to each other).

4x-5x-1=-8 (Subtract 5x on both sides)

-x-1=-8 (Combine like terms)

-x=-8+1( Add 1 on both sides)

-x=-7 (Now since you have a negative sign on both sides you can cancel them)

x=7 ( Making that as your answer!!)

There is a mistake in your writing

:The similar triangles should be ABE (& not ABD as you stated) & ACD

If so, we can write the following proportion:

AB/AC = BE/CD.

We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22

Plug into the above: 10/22 =4/y===> y= (22 x 4)/10===> y =44/5 =8.8

2) y=0

3) x=3

4) 2y + (3*3y) = -15

The arithmetic sequences always graph as points along a line.

In a geometric sequence, each term is equal to the previous term, multiplied (or divided) by a constant.

The exponential functions have a very special property:

equal changes in the input cause the output to be successively multiplied by a constant.

Geometric sequences also have this same special property:geometric sequences always graph as points along the graph of an exponential function.

The sequence 6.25,12.5,25,50,100 is a geometric sequence so its graph will represent a geometric sequence.
