Answer:

The height of the model is 2 feet 10.5 inches.

Step-by-step explanation:

Given:

scale of 1/3 inch=2ft

actual tower is 207 feet

To Find:

The height of the model = ?

Solution:

We know that 1 feet is 12 inches

Then 2 feet is $12 \times 2$ = 24 inches

24 inches= $72 \times \frac{1}{3}$ of a inch.

The tower is 72 times the scale of the model.

Now the actual tower is 207 feet

$\frac{207}{72}$ = $\frac{23}{8}$ , units feet

=> $2 \frac{7}{8} feet$

=> 2 feet 10.5 inches.

A car is traveling at 46 mph. it its tires have a diameter of 26 inches, how fast are the car's tires turning? express the answe

leva [86]

Circumference of the tire:

PI x diameter = 3.14 x 26 = 81.6814 Round to 81.68

Speed of the car in inches per minute:

46*5280*12/60 = 48576 inches per minute

48576/81.68 = 594.711

Round to 594.71 revolutions per minute

How do I get (tan^2(x)-sin^2(x))/tan(x) equal to (sin^2(x))/cot(x)

shepuryov [24]

$LHS\\ \\ =\frac { \tan ^{ 2 }{ x-\sin ^{ 2 }{ x } } }{ \tan { x } } \\ \\ =\frac { 1 }{ \tan { x } } \left( \tan ^{ 2 }{ x-\sin ^{ 2 }{ x } } \right)$

$\\ \\ =\frac { \cos { x } }{ \sin { x } } \left( \frac { \sin ^{ 2 }{ x } }{ \cos ^{ 2 }{ x } } -\frac { \sin ^{ 2 }{ x\cos ^{ 2 }{ x } } }{ \cos ^{ 2 }{ x } } \right) \\ \\ =\frac { \cos { x } }{ \sin { x } } \left( \frac { \sin ^{ 2 }{ x-\sin ^{ 2 }{ x\cos ^{ 2 }{ x } } } }{ \cos ^{ 2 }{ x } } \right)$

$\\ \\ =\frac { \cos { x } }{ \sin { x } } \cdot \frac { \sin ^{ 2 }{ x\left( 1-\cos ^{ 2 }{ x } \right) } }{ \cos ^{ 2 }{ x } } \\ \\ =\frac { \cos { x } }{ \sin { x } } \cdot \frac { \sin ^{ 2 }{ x\cdot \sin ^{ 2 }{ x } } }{ \cos ^{ 2 }{ x } } \\ \\ =\frac { \cos { x } \sin ^{ 4 }{ x } }{ \sin { x\cos ^{ 2 }{ x } } } \\ \\ =\frac { \sin ^{ 3 }{ x } }{ \cos { x } }$

$\\ \\ =\sin ^{ 2 }{ x } \cdot \frac { \sin { x } }{ \cos { x } } \\ \\ =\sin ^{ 2 }{ x } \cdot \frac { 1 }{ \frac { \cos { x } }{ \sin { x } } } \\ \\ =\sin ^{ 2 }{ x } \cdot \frac { 1 }{ \cot { x } } \\ \\ =\frac { \sin ^{ 2 }{ x } }{ \cot { x } } \\ \\ =RHS$
