Answer:

i think you can use this formula

$\cos( \frac{\pi}{12 } ) = \cos( \frac{\pi}{4} - \frac{\pi}{6} ) = - \cos( \frac{\pi}{6} ) = \frac{ \sqrt{3} }{2}$

(Help please) Find both the perimeter and the area of the following rectangle

Nikolay [14]

Given:

Length of a rectangle = (2x+3) units

Width of the rectangle = (x+6) units

To find:

The perimeter and the area of the rectangle.

Solution:

We know that, the perimeter of the rectangle is

$Perimeter=2(Length+Width)$

$Perimeter=2((2x+3)+(x+6))$

$Perimeter=2(3x+9)$

$Perimeter=6x+18$

The area of rectangle is

$Area=Length\times width$

$Area=(2x+3)\times (x+6)$

$Area=2x^2+12x+3x+18$

$Area=2x^2+15x+18$

Therefore, $Perimeter=6x+18$ and $Area=2x^2+15x+18$ .

A principal of $2000 is invested at 7% interest, compounded annually. How much will the investment be worth after 10 years? Use

zubka84 [21]

Answer:

$4,027.51

Step-by-step explanation:

Use the formula P*e^(r * t)

P = principal amount

e = the constant e

r = rate

t = time, in years

2,000 * e ^ (0.07 * 10)

2,000 * e ^ (0.7) ≈ 4,027.51
