to solve this, you have to do a lot of reverse calculations. g = 4.5 e.2t 4= 4.5 e.2t divide both sides by 4.5 .889 = e.2t take the natural log of both sides (ln) -.1178 = .2t divide both sides by .2 -.5889 = t

stem and leaf plots are used to easily see large amounts of data. usually, you take the first digits and place them on one side of the table- the stem side, and the rightmost digit on the left side- the leaf side. for example, the number ten would be 1 | 0 or the number 135 would be 13...

an angle is the conjoining point between two intersecting lines. these can be measured in degrees or radians. for example, a triangle ("tri- angle") has three angles, with all three adding up to 180 degrees. a square/rectangle has four angles, all of which are 90 degrees.  /_...

for this question, it helps to know what cards are in the deck. since there are four of everything (four suits), there will be four 8's and four kings. this means that we are aiming for one of 8 cards. therefore, 8/52= .1538 or answer C.

looks like you're just solving for y... in which case, add nine to both sides and you get y = 20

false. it will only be negative if the number is negative with an odd exponent. what you're actually doing is dividing instead of multiplying. for example: 42 = 16 4-2 = 1/16 basically, it is x-n =1/xn

because there is only one of them. technically speaking, you don't need to do that. you're essentially saying "one times b"

the best way to do this is to break it down. the first part says, four times the reciprocal of a number. this can be translated to: 4* (1/x) the second part is 8 times the reciprocal of 24. this translates to: 8*(1/24) so now we just set these equal to each other and solve for x...

The compound interest equation is P = C (1 + r/n)(nt). Where P is the calculated value, C is the initial amount, r is the interest rate, n is the # of times per year the interest is compounded, and t is the number of years invested. If you need 70,000 in 7 years...

Yes, Yes, a million times, Yes! Ender's game is a fantastic sci-fi book that delves into the mind of a tactical genius. I have read the book three or four times and each time I learn something new. The biggest part of this book is that it teaches what it means to be human, not so much by comparing...

I don't know that To Kill a Mockingbird is influential to today's culture, but it is a reminder of our past. The book discusses various topics including racism, social constructs, rape, and murder. The most important part of the book for me, was in the discussion on racism. The father of the main...
