Answer:

Area of the rectangle = 144 square inches

Step-by-step explanation:

Area of a rectangle = length × width

Width = 4 inches

Length = 3 feet

1 feet = 12 inches

3 feet = 36 inches

Area of a rectangle = length × width

= 36 inches × 4 inches

= 144 square inches

Therefore,

Area of the rectangle = 144 square inches

Mrac [35]

To add 11% to an amount means to multiply the amount by 1.11.

You can start with $115 and multiply it by 1.11 eleven times.

A quicker way is to find 1.11^11 and then multiply by $115.

$115 * 1.11^11 = $115 * = 3.151757 = $362.45

Simplify the following expression. cot^2x secx-cosx

Solnce55 [7]

ANSWER

$\cos(x) \cot ^{2} (x)$

EXPLANATION

The given expression is;

$\cot^{2} (x) \sec(x) - \cos(x)$

Change everything to

$\sin(x)$

and

$\cos(x)$

This implies that,

$\frac{ \cos^{2} (x) }{ \sin^{2} (x) } \times ( \frac{1}{ \cos(x) } )- \cos(x)$

Cancel the common factors,

$\frac{ \cos(x) }{ \sin^{2} (x) } \times ( \frac{1}{1} )- \cos(x)$

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

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

$= \frac{ \cos(x)(1 - \sin ^{2} (x) ) }{ \sin^{2} (x) }$

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

$= \cos(x) \cot^{2} (x)$
