The coefficient of y∧15×∧2 in expansion of (y∧3+x)∧7 is (15×2)+(3×7)= 51
Step-by-step explanation:
y-75
Answer:
h(f(x)) = x
Step-by-step explanation:
Since the functions are inverses h(x) undoes f(x)
That is if f(x) = x then inverse function maps back to x
h(f(x)) = x

Answer:
3 1/5
Step-by-step explanation:
Okay, this is a standard division problem, so our equation is:
2 2/5 ÷ 3/4
but then we have to covert the mixed number to an improper fraction:
12/5 ÷ 3/4
do the cross thingy:
4/5 x 4/1 = 16/5 = 3 1/5
So Jason can cut 3 1/5 sections or 3 if you round
