Scientific notation is written as #.## x 10^#.
Our number, 3,050,000, needs to be written in scientific notation.
The best way to write scientific notation is by "#.## x 10^#".
In this case, it will be 3.05 x 10^#, # being the amount of times we move the decimal to the right. We have moved it 6 times to the right, so our expression is:
3.05 x 10^6.
I hope this helps!
Answer:
B, D, E
Step-by-step explanation:
The parenthesis can be removed and this is the same answer as D.
Moving the parenthesis to the first two terms gives B.
Lastly using multiplication sign rules that say -(-) = +, E is the same expression.
He can buy up to 71 trees with $1000. He could also buy up to 199 bushes with $1000. Any combination of the two would work.
You need the number of miles per kilometer, or vice versa.
Answer:
Horizontal tangent
(x, y) = (1, 0)
Vertical tangent
(x, y) = DNE
Step-by-step explanation:
The equation for the slope (m) of the tangent line at any point of a parametric curve is:
Where 
and 
are the first derivatives of the horizontal and vertical components of the parametric curves. Now, the first derivatives are now obtained:
and 
The equation of the slope is:
As resulting expression is a linear function, there are no discontinuities and for that reason there are no vertical tangents. However, there is one horizontal tangent, which is:
The point associated with the horizontal tangent is:
The answer is:
Horizontal tangent
(x, y) = (1, 0)
Vertical tangent
(x, y) = DNE
