Your science teacher has a 1:200 scale model of the space shuttle Atlantis. Which of the proportions can you use to find the act

ual length x of Atlantis? Explain
a- 1/200 = 19.5/x
b- 1/200 = x/19.5
c-200/19.5=x/1
d-x/200=1/19.5

Answer: B. (1/200 = x/19.5)

 

EXPLANATION

 

Space shuttle Atlantis model scale 1:200

Length of Atlantis on model = 19.5

The actual length of Atlantis = x

Find x

 

Scale = 1:200; in decimal = 1/200

When length on model = 1

Actual length = 200

 

When actual length = x

Length on model = 19.5

Scale = x:19.5 ; in decimal = x/19.5

 

Equating both scales,

1/200 = x/19.5 (Option B)

Differentiating a Logarithmic Function in Exercise, find the derivative of the function. See Examples 1, 2, 3, and 4.
kotykmax [81]

Answer:

f'(x) = -\frac{2x}{1 - x^{2}}

Step-by-step explanation:

The derivative of an addition/subtraction of terms is the addition/subtraction of the derivatives of these terms.

The derivative of a constant is 0.

The derivative of a*x^{n} is a*n*x^{n-1}. The derivative of x^{3} is 3x^{2}, for example.

The derivative of the ln function:

If we have:

y = \ln{g(x)}

The derivative is

y' = g'(x)*\frac{1}{g(x)}

In this problem, we have that:

y = \ln{1 - x^{2}}

So g(x) = 1 - x^{2} and g'(x) = -2x

So the derivative to this function is

f'(x) = -\frac{2x}{1 - x^{2}}
