The stock of Company A gained 2% today to $79.56. What was the opening price of the stock in the beginning of the day?

CaHeK987 [17]

Answer: $78

Step-by-step explanation:

From the question, we are informed that the stock of Company A gained 2% today to $79.56. The opening price of the stock in the beginning of the day will be calculated as:

= [100% / (100% + 2%)] × 79.56

= (100% / 102%) × 79.56

= 1/1.02 × 79.56

= 79.56/1.02

= 78

Therefore, opening price of the stock in the beginning of the day is $78

Does anyone know how to solve this?

Margarita [4]

Answer:

The correct option is c.

Step-by-step explanation:

Given that,

u = 7i+4j and v = 2i-3j

We need to find the product of u and v. The dot product of two vectors is given by :

$u{\cdot}v=(7i+4j){\cdot} (2i-3j)\\\\=(7i)(2i)+(4j)(-3j)\\\\=14-12\\\\=2$

So, the dot product of u and v is equal to 2.
