Harita still needs to memorize, as a function of d, the number of days of practice since she began learning the piece <span>m = 90 - 6d</span>
Given the equation:
You know that the radioactive substance has this half-life (in years)
And:
Therefore, you can rewrite the equation in this form in order to find "k":
Solve for "k":
For lines to be perpendicular they would need to have opposite slopes, so for a slope of -3/7 the slope of a perpendicular line would be 7/3
They all use the metric unit to measure things (e.g. inches, centimeters, etc.)
As far as I know, I think the difference might be that a yardstick only measures 1 yard. It has 36 inches (which is 3 feet, which is also 1 yard).
A ruler usually is only 12 inches.
A measuring tape is usually 12 feet.
That's what I know.
