First we use product rule
y=x^2lnx
dy/dx = x^2 d/dx (lnx) + lnx d/dx (x^2)
dy/dx = x^2 (1/x) + lnx (2x)
dy/dx = x + 2xlnx
now taking second derivative:
d2y/dx2 = 1 + 2[x (1/x) + lnx (1)]
d2y/dx2 = 1 + 2[1+lnx]
1+2+2lnx
3+2lnx is the answer
Answer:
y = -2x + 5
Step-by-step explanation:
Assuming this is linear, the slope would be constant. For every 1 x, y decreases by 2. This means that the slope is -2.
y = -2x + b
Now all we need is the y-intercept.
If we plug in the first point (1,3), we get:
3 = -2*1+b
3 = -2+b
b = 5
This is the y-intercept.
y = -2x + 5
base = 3*3 = 9 sq. in.
side = 1/2 *3*6 = 9 sq. in.
4 sides x 9 = 36 + 9 (base) = 45 in^2
Answer is A
Answer:
no rain today = 35%
Step-by-step explanation:
In probability, the Complement Rule states that the sum of the probability of an event and its complement must = 1
i.e
P( Event) + P (Complement) = 1
In this sense, we can think of the complement of an event as the "not-event". I.e the event does not happen.
In our case, the event = "rain today",
hence the complement will be = "not rain today" (i.e no rain today)
using the formula above, we are given that P(rain today) = 65% = 0.65
hence
0.65 + P(Complement) = 1
P(Complement) = 1 - 0.65 = 0.35 = 35%
