In an arithmetic sequence {an}, if a1 = 5 and d = 3, find a72. A) 216 B) 218 C) 221 D) 223

Phoenix [80]

The arithmetic sequence with the given condition is determined recursively by

$\begin{cases}a_1=5\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}$

So we have

$a_2=a_1+3$

$a_3=a_2+3=a_1+3(2)$

$a_4=a_3+3=a_1+3(3)$

and so on with the general pattern

$a_n=a_1+3(n-1)$

This means the 72nd term in the sequence is

$a_{72}=a_1+3(72-1)=5+3(71)=218$

so the answer is B.

a satellite's escape velocity is 6.5 mi/sec, the radius of the earth is 3960 mi, and the earth's gravitational constant is 32.2

Artyom0805 [142]

Answer:

$23.89x10^{6}$ ft

Step-by-step explanation:

$\frac{V^{2} }{R^{2} } = \frac{2g}{R+h} \\$ This is the formula to find satellite's escape velocity V , where R is earth's radius, h is the satellite's height from the earth surface and g is the earth's gravitational constant.

$R^{2}(R+h) \frac{V^{2} }{R^{2} } =R^{2} (R+h)\frac{2g}{R+h}$ (Multiplying to clear the fractions)

(R+h) $V^{2} =R^{2} 2g$

$R+h=\frac{2R^{2}g }{V^{2} }$

$h= \frac{2R^{2} g}{V^{2} } -R$

Now, we can determine height of satellite from the surface of the earth

by putting the values in above equation

$h= \frac{2 * (3960)^{2}*32.2 }{6.5^{2} } -3960\\h= 23.902 x10^{6} - 3960\\ h=23.89x10^{6} ft$

A sequence is defined that the first term is 4 and each term after the first term is found by adding 4 5 to the preceding term.

The 8th term of the sequence is 9.6
Hope this helped! :)
