What is an
equation of the line that passes through the points (-3,-2) and (3,6)?

Answers

Answer:

y = 4/3x + 2

Step-by-step explanation:

y2 - y1/ x2 - x1

6 - (-2)/ 3 - (-3)

= 8 / 6

= 4/3

y = 4/3x + b

6 = 4/3(3) + b

6 = 4 + b

2 = b

3 numbers are in arithmetic progression their sum is15 and their product is 80 determine the 3 numbers

Answers

Answer:

2, 5, 8

Step-by-step explanation:

For starters, let us assume that the numbers are x-d, x, and x+d.

Where d is the common difference between terms.

This mean that we can say, from the question

x-d + x + x+d = 15

3x = 15,

x = 5,

This means that the terms are 5, 5-d and 5+d.

On the other hand,

(5-d) * 5 * (5+d) = 80

(5-d) * (5+d) = 80/5

(5-d) * (5+d) = 16

25 - d² = 16

d² = 9

d = + or - 3.

Finally, the three numbers will be 2, 5, and 8. On the flipside, their sum and product are 15 and 80.

8-50. What is the area of a regular decagon if the length of each side is 20 units? Show all your work.

Answers

Answer:

3077.68

Step-by-step explanation:

the Area of the regular decagon is 3077.68

The area of the decagon with side length of 20 units is -

A = 1000√(5 + 2√5) square units.

What is Area?

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write area -

V = ∫∫F(x, y) dx dy

Given is a regular decagon with length of each side is 20 units

The area of the regular decagon is -

A = (5/2)a²√(5 + 2√5)

We have {a} = 20. So, we can write that -

A = (5/2)(20)²√(5 + 2√5)

A = (5/2) x 400 x √(5 + 2√5)

A = 5 x 200 x √(5 + 2√5)

A = 1000√(5 + 2√5)

Therefore, the area of the decagon with side length of 20 units is -

A = 1000√(5 + 2√5) square units.

The perimeter of ABCD is 26 cm

The area of PQRS is 45 cm(squares)
Find the length of AB

Answers

Area of rectangle= LxW
45cm2 divided by 10cm = 4.5cm
B-C= 4.5cm
Perimeter of rectangle= L+W x2
26/2 =13cm -4.5= 8.5cm

QR = 10cm and the area of that rectangle is 45cmsq so to work out PQ you do 45/10 = 4.5cm
PQ= 4.5cm

As BC = PQ they both equal 4.5cm

and the perimeter of ABCD is 26cm you so 26- (4.5x2) = 17
and 17/2 = 8.5cm

AB is 8.5cm

Jackie purchases 100 bracelets from a wholesaler at $10 each and the cost totals $1,000. If
Jackie does a markup of 40%, what will the markup amount be? What will the price of each
bracelet be?

Answers

Using proportions, it is found that:

The markup amount is of $400.The price of each bracelet is of $14.

What is a proportion?

A proportion is a fraction of a total amount.

In this problem, the markup is of 40% over an amount of $1000, hence:

0.4 x $1000 = $400.

Considering the markup, 100 bracelets will be sold for $1,400, hence, the price of each bracelet will be given by:

$1,400/100 = $14.

Answer:

x= 25.5 not rounded x=25.51393657

Step-by-step explanation:

Decide what trig ration you need/want to use. The 27 degrees are opposite of the 13 and adjacent to the x which means your ratio should be o/a or 13/x. The trig ratio needed is Tangent. Now you can write the equation as tan(27)=13/x and start solving.

tan(27)=13/x multiply the x on both sides and you'll have x * tan(27)=13 and decide which to put into your calculator and you'll get x=25.51393657 rounded as 25.5
