Answer:
C(n, 2)a^(n-2)b^2
Step-by-step explanation:
Generally, the expansion is written in decreasing powers of "a", so the first few terms would have variable constellations that look like ...
a^n, a^(n-1)b, a^(n-2)b^2, ...
The coefficients would be (in order), C(n, k) for k increasing from 0, so the coefficient of the 3rd term would be C(n, 2).
C:65% Would be the answer i believe you're looking for, hope this helps!
Answer:
B
Step-by-step explanation:
The y-axis shows the number of gallons of water left (with respect to time).
The x-axis shows the time.
Domain is the set of x-values that is allowed. Looking at the graph, we see that the water drains within 0 to 12 minutes. After 12 minutes there is no water left, so that's not feasible. Hence, the domain would be from 0 to 12.
Looking at the choices, that is B, 0 ≤ x ≤ 12
Answer:
5, 1 , -3 ,-7
Step-by-step explanation:
When x = -1
y = - 4 * (-1) + 1
= 4 + 1
= 5
When x = 0
y = - 4 * 0 + 1
= 0+ 1
= 1
When x = 1
y = - 4 *1 + 1
= - 4 + 1
= - 3
When x = 2
y = -4 * 2 + 1
= - 8 + 1
= - 7
