Answer:
A. 502.4 cm^3
Step-by-step explanation:
r=8/2=4 cm
V=pi*r^2*h=3.14*16*10=502.4 cm^3 (A)
Answer:
x=ln(2)/3
Step-by-step explanation:
e^3x+6=8
e^3x=8-6
e^3x=2
ln(e^3x)=ln(2)
3x=ln(2)
x=ln(2)/3
Catherine has 12.
2 times 3 is 6. 6 times 2 is 12. Final answer is 12.
Answer:
B. 199
Step-by-step explanation:
We are given an Arithmetic sequence : 3, 7, 11, 15, ...
We are supposed to find the 50th term .
So, first consider the formula of nth term in Arithmetic mean:

where
a is first term of sequence
n is term position
d is common difference
= the term you are supposed to find
Now,
a = 3 ( first term )
n = 50 th term ( given )
d = 7-3 = 11-7 = 4(common difference
Substitute these value in the formula given above
⇒
⇒
⇒
⇒
Hence ,The 50th term of given arithmetic sequence is 199
So, OPTION B is correct .
Answer:
b=16
Step-by-step explanation:
