Assessing negative exponents on your calculator
With your dilemmas, you will need to raise figures to negative abilities. Many calculators have button that is separate negating a quantity that is unique of the subtraction switch. Some calculators label this (-) , some with +/- . The switch is normally nearby the = key or perhaps the decimal point.
Should your calculator shows operations about it (typically a calculator with multiline display), to calculate 1.005 -240 youвЂ™d type something similar to: 1.005 ^ (-) 240
Then usually you hit the (-) key after a number to negate it, so youвЂ™d hit: 1.005 yx 240 (-) = if your calculator only shows one value at a time,

A donor provides $100,000 up to a college, and specifies it is to be utilized to offer scholarships that are annual the following twenty years. In the event that college can make 4% interest, simply how much can they provide in scholarships every year?
r = 0.04 4% yearly price
k = 1 since weвЂ™re doing scholarships that are annual
P0 = 100,000 weвЂ™re you start with $100,000
re Solving for d gives $7,358.18 every year they can surrender scholarships.
It really is well well well well worth noting that always donors alternatively specify that only interest is to be utilized for scholarship, helping to make the first contribution final indefinitely. If this donor had specified that, $100,000(0.04) = $4,000 a 12 months might have been available.
