For the scientific notation, write the standard form: 5.61 x 102

The standard form is 5.61 x 10^2

Step-by-step explanation:

The standard form for a scientific notation is expressed as A * 10^n

A is any value between 1 and 10

n is an integer

Given the notation 5.61 x 10^2, this is already in scientific notation since;

A = 5.61 which is between 1 and 10 and n = 2 which is a positive integer

the 3rd option is right

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
