Answer:
He is false
Step-by-step explanation:
Hey there!
The area of a shape is the total measurement of the inside of the shape
Meaning the parts I shaded in the screenshot
As you can see in the image, there is less area in shape B than shape A
Meaning, that the area has decreased
Now, Tom says that both area and perimeter has decreased
Lets check if the perimeter has decreased
If you look at it, the perimeter hasn't decreased at all
All that has happened was the shape getting a new form
The dimension are basically split
For example, if the top side of the square was 6 inches
Then the dimension after taking out a square from the shape would split
The top side of that square after is was split would be something along the ligns of 4 inches, and 2 inches and other dimensions like that
That is how I think of the perimeter and if it changes or not
But this explains why Tom is wrong
Since the perimeter is still the same
Tom is wrong
The given function is a quadratic equation. Any quadratic equation can be written in the form :
The given points can be taken as (2,23) ,(4,55) and(10,247)
We form three equations with the given points
For point (2,23 ) the equation is
23 = 4a + 2b + c
For point (4,55) the equation is
55 = 16a + 4b + c
For point (10,247) the equation is:
247 = 100a+10b+c.
Solving the three equations for a,b,c we have :
32 = 12a + 2b
16 = 6a + b
and,
192 = 84 a + 6b
32 = 14a + b
Solving for a,b,c we have:
a=2 b=4 c=7
The quadratic equation is c(x)=
When x=8
c(x)=]
Option C. $167 is the right answer.
