Answer:
A= 10 units squared
Step-by-step explanation:
Because we are fully given points A and B, as well as the knowledge that ABC is a right triangle, we can assume that point C is the last needed point to form the right angle of this triangle. Meaning, point c has to have <em>one</em> identical coordinate out of (x,y) that is the same from <em>each</em> of our pre-existing coordinates in order to successfully form a right angle.
Due to the fact that we are told that Point C lies on y=2, we know that it already has an identical 'y' coordinate as Point A.
We can now decode that the x coordinate of Point C must be identical to the x coordinate of Point B, In this case, -2
We can conclude that point C lies on (-2,2)
If we look at the length of the sides of the triangle, ignoring the hypotenuse, we can see that one is 4 units long and the other is 5 units long.
To find the area of a square the formula is A= l x w x 0.5
Since 4x 5 = 20 and half of 20 is ten, we know that the final answer will be 10 units^2

Answer:
Part A: 15
Part B:
Point slope form: 
Slope intercept form: 
Standard Form: 
Part C: 
Part D: 505
Step-by-step explanation:
We are given the following
x g(x)
5 $400
10 $475
We can see that these are two points on the line.
i.e. (5, 400) and (10, 475)
OR

<u>Part A: </u>Slope of the function:

So, slope of the line = 15
<em>It has a positive slope and the function will be increasing with the increasing value of 'x'.</em>
<em></em>
<u>Part B:</u>
Point slope form of a line is given as:

Putting
:

Slope intercept form:
where c is the intercept.

Putting (x,y) as (5, 400) to find c:

So, the equation in slope intercept form:

Standard form of line:

Rewriting the slope intercept form:

<u>Part C:</u>
Using the function notation, putting y = g(x) in slope intercept form:

<u>Part D:</u>
Balance after 12 days = ?
i.e. g(x) = ? at x = 12
Putting x = 12 in 

Answer: 19/22
Step-by-step explanation:
= 3 + 4/11 - 2 -1/2
Then, 3-2= 1
Next, 4/11 -1/2= ?
LCD of 4/11 and 1/2 and you would get this 8/22 - 11/22= 3/22
Finally, 1 - 3/22 = 19/22

Answer:
She can paint <u>6 rooms</u>.
Step-by-step explanation:
Given:
Maya decided to paint some of the rooms in her hotel. She found out that a room required 3/2 cans of paint.
If Maya buys 9 cans of paint.
Now, to find the rooms she can paint.
So, we use unitary method to get the number of rooms:
If,
cans of paint is needed to paint 1 room.
Then, 1 can of paint is needed to paint =
room.
Thus, 9 cans of paint is needed to paint =

Therefore, she can paint 6 rooms.
Answer:
- 24x + 9
Step-by-step explanation:
Differentiate each term using the power rule
( a
) = na
Given
f(x) = - 12x² + 9x, then
f'(x) = (2 × - 12)x + (9 × 1)
= - 24x + 9
