It looks like part of your question got cut off, but from the information provided you should use the equation q=mcΔT, where q is heat, m is mass, c is specific heat capacity, and ΔT is the temperature change (final temperature - initial temperature)
q = ?
m = 47 kg = 47,000 g
(a + b)^4 = a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + b^4
First you need to figure out the slope of the given line (2x - 4y =5) by putting it in slope intercept form (y = mx + b).
subtract 2x from both sides to get -4y = -2x - 5
divide both sides by -4 to get y = (1/2)x + (5/4)
So the slope of this line is 1/2.
Any lines that are...
Numbers in scientific notation consist of two parts - a base number that is greater than or equal to one and less than 10, and a multiplier of 10 raised to an exponent.
Locate the decimal point in the number in question (if no decimal point, create one at the very end of the number). Move...
To put a number into standard notation from scientific notation, you move the decimal point in the base number (ie, 3.2) the number of spaces indicated by the exponent (ie, 4). If the exponent is negative, the decimal moves to the left (if positive, it
moves to the right). When you...
