Answer:

2520ft

Step-by-step explanation:

Calculation for what is the scale of the model?

Let x will be the span length

Hence,

x= 4200 feet long/20 inches long

x=210

Thus:

1 inch = 210 ft

1 ft = 2520

=2520ft

Therefore the scale of the model will be 2520ft

The black graph is the graph of y=f(x). Choose the equation for the red graph.<br> Please Help me!!
katen-ka-za [31]

Answer:

c

Step-by-step explanation:

The red graph is the black graph translated vertically by 1 unit

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Thus f(x) + 1

Note

y - 1 = f(x) ← add 1 to both sides

y = f(x) + 1 ← as required

The equation of the red graph is

y - 1 = f(x) → c

Which statement best defines the two quantities that are measured to find the rate at which an airplane descends? A) The quantit
Schach [20]

The <em>correct answer</em> is:


C) The quantity of distance measured in feet depends on the quantity of time measured in minutes.


Explanation:


The rate of an airplane's descent would be found using the distance it descends and the amount of time that takes.


In this situation, the amount of time that passes causes the distance the plane descends to change; this means that the distance depends on the time.
