Prove that the inverse of an invertible mapping is invertible?
Assume that f:S->T is invertible with inverse g:T->S, then by definition of invertible mappings f*g=i(S) and g*f=i(T), which defines f as the inverse of g. So g is invertible.
What mathematical equation does law of free fall has?
s = 1/2 g t squared (s = 1/2 gt^2) s = distance g= acceleration of gravity t = time
What s the G of x if it equals log 2 x plus 2?
G(x) = log(2x) + 2, obviously!
How to find the side of the square with an area of 256m squared?
A = s^2 256 m^2 = s^2 √(256 m^2) = √(s^2) 16 m = s Thus, the side of the square has a length measure of 16 m.
One half of the students in alex's science class are girls one third of the girls in the class have blonde hair if 10 girls do not have blonde hair how many students are in alex's science class?
Let's say that s is the total number of students, b is the number of boys, g is the total number of girls, n is the number of non-blonde girls, and e is the number if blonde girls. We know that s = b + g, b = g, g = n + e, e = g/3, and n = 10. Substituting for b in the first equation gives us s = g + g = 2g Then we substitute for n and e in the third equation and solve for g: g = g/3 + 10 g - g/3 = 10 g - (1/3)g = 10 (2/3)g = 10 g = 10 x (3/2) = 15 Finally, solve for s: s = 2g = 2 x 15 = 30

What has the author G M L Gladwell written?
Malcolm Gladwell has written several bestselling books such as "Outliers," "Blink," and "The Tipping Point." He is known for exploring social and psychological phenomena in an engaging and thought-provoking way.
Are absolute value and additive inverse equal why?
No. This is because absolute values are always positive. For example: |2|=2 absolute value Additive inverse means the opposite sign of that number so 2's additive inverse is -2. But sometimes if the number is -2 then the additive inverse equals the absolute value. therefore the answer is sometimes
What is Inverse-Square rule of gravitation?
You are at earths surface (call this 1 radius (1r) from earth center) with acceleration due to gravity at say 10 (m/s)/s, if you double your distance (in terms of radius this = 2r) and install in equation: a= 10/(2(r)^2) inverse square law a= 10/4 a= 2.5 (m/s)/s 2* distance = 1/4 the gravity 3* distance = 1/9 the gravity 4* distance = 1/16 the gravity
What is G. E. M.'s birthday?
G. E. M. was born on August 16, 1991.
What is the formula for free fall aceleration?
d = -(1/2)g*t^2 v = - g*(squareroot(2(d/g))) wrong the real formula is: h=-16t^2+s h= ending height usually 0" t=time s= starting height (example) 0=-16t^2+256 -256 -256 -256=-16t^2 __________ -16 16=t^2 t=4 seconds They're both the same formula, they are just transposed. The ending height is always zero since you want the intermittent distance and time of that distance. d = -(1/2)g*t^2 =-(1/2)(32)*t^2=-16*(t^2)

Is Na (g) plus 2HCl (g) H2 (g) plus 2NaCl (s) is a balanced equation?
No, it should be:2 Na(s) + 2HCl(g) --> H2(g) + 2 NaCl(s)By the way: sodium at normal conditions is a solid metal (s), not gaseous (g)
A compound is found to contain 50.05 percent sulfur and 49.95 percent oxygen by mass. What is the empirical formula for this compound?
Assuming 100 g of compound50.05 g S x 1 mol S/32 g S = 1.56 moles S present49.95 g O x 1 mol O/16 g O = 3.12 moles O presentmole ratio of O to S is 3.12/1/56 = 2 to 1Empirical formula = SO2
