So 0.344 means 344/1000
(0.1=1/10 0.21=21/100 0.213=213/1000)
factor out the 'ones' (exg 4/8=1/2 times 4/4[4/4=1 so it can be canceled out])
344=2*2*2*43
1000=2*2*2*5*5*5
we notice that there is a 2*2*2 in both groups so we can cross it out (or 2*2*2=8 so divide top number and bottom number by 8)
43/(5*5*5)
43/125
Answer: C - distributive property of multiplication over subtraction
Step-by-step explanation:
Answer:
332 - 333, for nearest its 333
Step-by-step explanation:
I don't understand what you mean by 'mentally' but anyways, here is how to solve it.
(z−12)(z+12)
=(z+−12)(z+12)
=(z)(z)+(z)(12)+(−12)(z)+(−12)(12)
=z^2+12z−12z−144
=z^2−144
F(x) = one fourth to the power of x-2 f(x) = (1/4)^(x-2)
It is a decreasing function that when x= 2, (1/4) is raised to the zero power which is 1, which is what the point (2,1) asks for.
