Detailed explanation-1: -Answer: 0.0056 is 5.6×10−3 in standard form.
Detailed explanation-2: -0.0018 = 1.8 1000 = 1.8 × 1 1000 = 1.8 × 10−3. This alternative form is called scientific notation and is based on the fact that moving the decimal point to the left or right in a number is equivalent to multiplying the number by a power of 10 (negative powers amount to dividing).
Detailed explanation-3: -The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it’s pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
Detailed explanation-4: -Answer and Explanation: In scientific notation 0.005 is 5×10−3 5 × 10 − 3 . To convert 0.005 to scientific notation we first move the decimal place to the right by 3 places, giving us just 5.
