So, in order, you have to multiply first. 3x3=9, now you have to do 2+2=4. Since there is a "plus" in between "2+2" and "3x3" you have to add, 9+4=13.

Which equation represents the area of the triangle? A) A = 1 2 (AC)(AB)(sin A) B) A = 1 2 (AC)(BC)(sin A) C) A = 1 2 (BC)(BD)(si

Juliette [100K]

Answer:

The correct option is A.

Step-by-step explanation:

Let the vertices of the triangle be ABC.

Draw a perpendicular on AC from B. The height of triangle is represented by the altitude from B.

$\sin A=\frac{BD}{AB}$

$AB\sin A=BD$

Area of the triangle is

$A=\frac{1}{2}\times base\times height$

$A=\frac{1}{2}\times (AC)\times (BD)$

$A=\frac{1}{2}\times (AC)\times (AB)\sin A$

$A=\frac{1}{2}(AC)(AB)\sin A$

Therefore option A is correct.

Answer:

During the first year he had an annual interest of 12%, and in the second year of 25%

Step-by-step explanation:

To calculate the interest of the first year:

(Initial capital of the first year / final capital of the first year) - 1 = interest of the first year

(300/336) - 1 = 0.12 = 12%

To calculate the interest of the second year:

(Initial capital of the secondyear / final capital of the second year) - 1 = interest of the second year

(336/420) - 1 = 0.25 = 25%
