Answer:
Step-by-step explanation:
According to the blueprint, the floor area of the stage in the new auditorium at my college must be rectangular and equal to 1200 sq. feet.
If the width of the stage is w feet and depth of the stage is equal to d feet, then being a rectangle, we can write
Therefore, the equation that represents the depth d as a function of width w is given by (Answer)
Question s Incomplete; Complete question is given below;
There is a mound of g pounds of gravel in a quarry. Throughout the day, 400 pounds of gravel are added to the mound. Two orders of 900 pounds are sold and the gravel is removed from the mound. At the end of the day, the mound has 1,500 pounds of gravel. Write the equation that best describes the situation.
Answer:
The equation that best describes the situation is .
Step-by-step explanation:
Given:
Amount of gravel present initially = ''.
Now Given:
Throughout the day, 400 pounds of gravel are added to the mound.
So we can say that;
Amount of gravel after addition =
Also given:
Two orders of 900 pounds are sold and the gravel is removed from the mound.
Now Two orders of 900 pounds =
So we can say that;
Amount of gravel after removing =
Now Given:
Amount left in mount at the end of the day = 1300 pounds.
So we can say that;
Hence the equation that best describes the situation is .
Answer:
See below
Step-by-step explanation:
For the model function ,
is the vertex, and
is the horizontal growth or shrink factor.
We know that our vertex is from our graph, so we'll need to determine the value of
by using one of the points on the graph:
Thus, our equation for the given graph is .
The domain of a function is the set of all existing real x-values, thus, our domain for the given function is , or all real x-values.
The range of a function is the set of all existing real y-values, thus, our range for the given function is , or all real y-values starting with y=-1 which is included.
