Answer:
945x^3·y^16
Step-by-step explanation:
The 5th term will be ...
C(7,4)(3x)^3(y^4)^4 = 35·27·x^3·y^(4·4)
= 945x^3·y^16
_____
The coefficients of the expansion are C(n, k) where n is the exponent of the binomial, and k+1 is the term number. This is n!/(k!(n-k)!). The general (k-th) term of the expansion (a+b)^n is C(n, k)a^(n-k)b^(k) where k ranges from 0 to n.
Answer:
The first answer choice is the correct one.
Step-by-step explanation:
Going from (1, 4) and ending up at (-2, 2), we see that the original point is now 3 units to the left of its starting position, and 2 units down.
Clarification: from x = 1 to x = -2 is 3 units (to the left), and
from y = 4 to y = 2 is 2 units (down)
The first answer choice is the correct one.
Answer:
shape is how it looks like Square is a shape and size is how big something in like my size of my foot is 6 inches
Step-by-step explanation:
well idk your real question i think it is that your shape and size can change
Fraction- 12/15
80% that it won't land on green
20%that it will land on green
(i wasn't sure what your ? was, so i put both choices.)
we are given
we can see that
degree of numerator = degree of denominator =2
so, we can divide both numerator and denominator by n^2
and we get
now, we can simplify it
now, we can plug n=inf
