aleksley [76]

Answer:

The answer is (-$200) to the left

Step-by-step explanation:

Solution

It is assumed that when a number is positive, it is a distance to the right, also when a number is negative, it is a distance to the left. If a positive number is referred to as deposit to a bank account, then a negative number is a withdrawal from that bank account.

So, If a positive number means addition, then a negative number would also mean subtraction.

The amount that represents a withdrawal of less than $200 would be (-$200)

they are identical. proved below.

Step-by-step explanation:

formula: $sin(t)+sin(s) = 2sin(\frac{t+s}{2} )cos(\frac{t-s}{2} )$

using the formula to proof:

$sin9a+sin5a$

$2sin(\frac{9+5}{2})* cos(\frac{9-5}{2})$

$2sin7a * cos2a$

True. proved that they are identical.
