Lindbergh's Air Speed Charles Lindbergh estimated that at the start of his historic flight the practical economical air speed wa

s 95 mph and at 4000 statute miles from the starting point it was 75 mph (www.charleslindbergh.com). Assume that the practical cconomical air speed S is a linear function of the distance D from the starting point as shown in the accompanying figure. Find a formula for that function.

The function based on the information will be S = -0.005D + 95.

<h3>How to illustrate the function?</h3>

It should be noted that d is the distance from the starting point while S is the speed.

The points given are (0 95)( 4000, 75).

Slope = (75 - 95)(4000 - 0)

= 0.005

The equation will be:

S = -0.005D + 95

Which of the following relations is a function?
MrMuchimi

Answer:

<em>A. (1,4), (-5, 2), (7, 1), (-8, 2)</em>

Step-by-step explanation:

<u>Definition of a Function</u>

A function is a relation between an input and an output set of values with the condition that every element in the input set relates only to one element in the output set.

From the four options presented in the question, we must select the only one that doesn't repeat the value for x and has a different value of y.

For example, the set

B. (1,4), (-5, 6), (1, 3), (-8, 2) is not a function because the input value of 1 has two different output values

C. (1,0), (-5,3), (7, 1), (-5,5) is not a function either because the input value of -5 has two different output values

The correct choice is:

A. (1,4), (-5, 2), (7, 1), (-8, 2)

The length of a rectangular park is four timesfour times its width. The park is surrounded by a 33​-foot-wide path. Let x denote
tiny-mole [99]

Answer:

A(x) = 4x^2 + 330x + 4356

Step-by-step explanation:

width of park: x

length of park: 4x

width + path width = x + 66

length + path width = 4x + 66

area = (x + 66)(4x + 66)

area = 4x^2 + 66x + 264x + 4356

area = 4x^2 + 330x + 4356

A(x) = 4x^2 + 330x + 4356
