The graphs below have the same shape. What is the equation of the red graph?
2 answers:
Answer:
The answer is A.
Step-by-step explanation:
Realize that the red graph is simply the blue graph shifted downwards. Hence, we simply need to subtract the units shifted from the original equation.
We see that the red graph shifted downwards by 3 units. Thus, we simply need to subtract three from the original equation.
Thus we have:
Which gives:
Here, 1 is also the y-intercept, verifying our answer.

Answer:
87.73 inches
Step-by-step explanation:
We are given that the dimensions of the rectangular doorway are,
Length = 6 ft 8 inches = 80 inches and Width = 3 feet = 36 inches.
Using Pythagoras Theorem, we will find the diagonal of the rectangular doorway.
i.e.
i.e.
i.e.
i.e.
i.e. Hypotenuse = ±87.73 inches
Since, the length cannot be negative.
So, the length of the diagonal is 87.73 inches.
As, the largest side of a rectangle is represented by the diagonal.
So, the largest dimension that will fit through the doorway without bending is 87.73 inches.
