What is the equation in point-slope form of the line passing through (3, 6) and (−2, 1)?
tankabanditka [31]

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (3, 6) and (-2, 1). Substitute:

m=\dfrac{1-6}{-2-3}=\dfrac{-5}{-5}=1\\\\y-6=1(x-3)

<h3>Answer: 4. y - 6 = 1(x - 3)</h3>

The figures below are based on semicircles and squares. Find the perimeter and the area of each shape. Give your answer as a com
irina1246 [14]

Answer:

Part 1) The area of the figure is A=48\ cm^2

Part 2) The perimeter of the figure is P=4(2+3\pi)\ cm

Step-by-step explanation:

Part 1) Find the area of the figure

we know that

The area of the figure is equal to the area of three squares

so

A=3[4^2]=48\ cm^2

Part 2) Find the perimeter of the figure

we know that

The perimeter of the figure is equal to two times the length side of the square, plus the circumference of six semicircles ( or the circumference of three circles)

Remember that

The circumference of a circle is equal to

C=\pi D

where

D is the diameter of the circle

In this problem

D=4\ cm

so

P=2(4)+3[\pi(4)]=(8+12\pi)\ cm

simplify

P=4(2+3\pi)\ cm

The Rodriguez family went to dinner at at Pasta Palace. Mr. Rodriguez ordered a meal for $6.25; Mrs. R ordered a meal for $7.50;
lidiya [134]
Cost of the meal ordered by Mr. Rodriguez = $6.25
Cost of the meal ordered by Mrs. Rodriguez = $7.50
Cost of each pizza ordered by the two children = $4.99
Then
The cost of the 2 pizzas ordered by the 2 children = (2 * 4.99) dollars
                                                                                 = 9.98 dollars
So
The total cost of the orders = (6.25 + 7.50 + 9.98) dollars
                                             = 23.73 dollars
Percentage of tip on the bill = 15%
Then
Amount of tip paid = (15/100) * 23.73 dollars
                              = 355.95/100 dollars
                              = 3.56 dollars
Percentage of tax paid on the bill = 7.25%
Amount of sales tax that was paid = (7.25/100) * 23.73 dollars
                                                       = 172.04/100 dollars
                                                       = 1.72 dollars
So
The total bill that was paid = (23.73 + 3.56 + 1.72) dollars
                                           = 29.01 dollars
