The speed at which a certain computer can access the internet is 2 megabytes per second. How fast is this in megabytes per hour.

Ainat [17]

$Converting\ units:\\\\ 2\frac{megabytes}{second}\\\\ 1second=\frac{1}{3600}h\\\\ 2\frac{megabytes}{second}*\frac{1}{\frac{1}{3600}}=2\frac{megabytes}{second}*\frac{3600}{1}=7200\frac{megabytes}{second}\\\\If\ 1second=\frac{1}{3600}\ you\ must\ multiply\ 2*\frac{1}{3600}\ to\ convert\ 1\ second\\ into\ hour.$

Which polynomial is in standard form?

Tamiku [17]

Answer:

D). $5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9$

Step-by-step explanation:

For better clarity let us re write the options

A). $2xy^3+3x^3y^4-4x^4y^5+9x^5y^6$

B). $8x^5-5y^4-2xy^5+x^2y$

C). $x^3y^2-3x^2y-9x^4y^3+11x$

D). $5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9$

To express polynomial with mixed variables in standard form, we begin by the highest coefficient of x to the smallest (we place high precedence on the coefficient x terms)
