Answer is A
It would be 2 root 2
bc it simplifies to root 2 and root 4
root 4 simplifies to 2
so its 2√2
Answer:
the answer should be 9/14
Step-by-step explanation:
you add them all up then subtract the red for your denominator
then just put the number of white on top for your numerator
Since f(x) is (strictly) increasing, we know that it is one-to-one and has an inverse f^(-1)(x). Then we can apply the inverse function theorem. Suppose f(a) = b and a = f^(-1)(b). By definition of inverse function, we have
f^(-1)(f(x)) = x
Differentiating with the chain rule gives
(f^(-1))'(f(x)) f'(x) = 1
so that
(f^(-1))'(f(x)) = 1/f'(x)
Let x = a; then
(f^(-1))'(f(a)) = 1/f'(a)
(f^(-1))'(b) = 1/f'(a)
In particular, we take a = 2 and b = 7; then
(f^(-1))'(7) = 1/f'(2) = 1/5
Answer:
7 quarters and 3 dimes
Step-by-step explanation:
x: quarter y: dime
25x + 10y = 205
x+y=10
y = 10-x
25x + 10*(10-x) = 205
25x+100 -10x = 205
15x = 105
x = 7
7 = 10-7 = 3
