When written in scientific notation, 3,900 = 3.9 x 10^3
Answer:
x = 7, -2
Step-by-step explanation:
<h2><em><u>
Factor and set each factor equal to 0</u></em></h2>
Parametrically for real t the line is



That's three equations; we substitute into





The intersection is a single point (7,-6,5).
Answer:
The result is 7.8 * 10^3
Step-by-step explanation:
When we are dividing in scientific notation, divide the numbers in front
7.8/1 = 7.8
Subtract the exponents on the powers of 10
10^(7-4) = 10 ^3
The result is 7.8 * 10^3
