Answer:
Coordinates of A prime will be (-4,0).
Step-by-step explanation:
Given:
ABC is a triangle on a grid with its coordinates in (x,y).
The coordinates are as follows:
According to the question.
The points are translated by (x-2,y+2) rule.
We have to find A prime i.e A' the coordinate of A after it is translated.
In translation we move the coordinates without rotating and resizing.
So
Point A after translation will be called A'.
⇒ A =
Subtracting 2 with the 'x' value and adding 2 with the 'y' value coordinate.
⇒ A' =
⇒ A '=
So the value of A prime after translating it by (x-2,y+2) is (-4,0).
Given:
A prism has a base area of square units and a volume of
cubic units.
To find:
The volume of the cylinder if the cylinder has the same base area and height.
Solution:
Volume of a prism is:
Where, B is the base area and h is the height of the prism.
The volume of cylinder is:
Where, r is the radius, h is the height of the cylinder and is the base area.
Since base area and height of the cylinder are same as the prism, therefore, there volumes are equal.
Hence the volume of the cylinder is cubic units.
Money earned by restaurant on Friday=$1073
Money earned by restaurant on Saturday=$1108
Let Money earned by restaurant on Sunday=$x
Average=$1000
Number of observation=3
⇒ 3× 1000=1073+1108+x
⇒3000= 2 181+x
⇒3000-2181=x
⇒x=819
The restaurant needs to earn on Sunday to average $1000 per day over the three-day period=$819
