Answer:
As only the length of the room changed. It means the length of the room is increased by 175%, because of which the area is increased by 175%.
Therefore, the expression become


And the area of Megan's room is increased by 0.75 square meters.
Step-by-step explanation:
- Let
be the length of the room
- Let
be the width of the room
So the area of the rectangle will be:

As the statement mentions that the new area of the room is
% of the previous area.
So the new area of the room becomes:

As only the length of the room changed. It means the length of the room is increased by 175%, because of which the area is increased by 175%.
Therefore, the expression become


also


so, the area of Megan's room is increased by 0.75 square meters.
Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (8, - 14), thus
y = a(x - 8)² - 14
To find a substitute (5, 13) into the equation
13 = a(5 - 8)² - 14
13 = a(- 3)² - 14
13 = 9a - 14 ( add 14 to both sides )
27 = 9a ( divide both sides by 9 )
a = 3
Thus
y = 3(x - 8)² - 14 → C
Answer:
if we take the total cost of the grapes, and divide by the number of pounds of grapes we can conclude that each pound of grapes costs $3. so 5 pounds of grapes multiplied by $3 per pound, gives us $15 for 5 pounds of grapes.
