Answer: f(x) = 7x

See this table

x [ ft^3 of air in the ballon]    f(x) [grams that can be lifted]

1                                          7
2                                          14
3                                          21

An airplane begins a descent to a sea-level airport at an angle of -4° to the horizon. What is the change in elevation after it
mote1985 [20]

Using the slope concept, it is found that the change in elevation was of -699 feet.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.

In this problem, we have that:

  • The vertical change is of h.
  • The horizontal change is of 10,000 feet.
  • The angle is of -4º.

Hence:

tan(-4º) = h/10000

h = 10000 x tan(-4º)

h = -699.

The graph of the equation y=f(x) passes through the points (-3,-5), (-2,-3),(0,1) and (4,9). What is the value of y in the equat
lapo4ka [179]
<h3>Answer:</h3>

-5

<h3>Explanation:</h3>

Each ordered pair is a list of an x-vaue and the corresponding f(x) value.

Hence the first ordered pair listed, (-3, -5), means that when x = -3, f(x) = -5. In other words, f(-3) = -5. By the transitive property of equality,

... y = f(-3) = -5

means

... y = -5
