11 th term of the following geometric sequence.<br> 10,50,250,1250

Natasha2012 [34]

Answer:

97,656,250

Step-by-step explanation:

The first term, a(1), is 10. The next is 5 times greater. And so on. Thus, the common ratio is 5, and the general formula for this sequence is

a(n) = a(1)*5^(n -1).

Therefore,

a(11) = 10*5^(11 - 1) = 10*5^10 = 97,656,250

Find the balance on a deposit of $455 that earns 4% interest compounded annually for 2 years. $36.40 $491.40 $492.13 $819

STatiana [176]

$A=P(1+ \frac{r}{n})^{tn}$
A=future amount
P=present amount
r=rate in decimal
n=number of times per year compounded
t=time in years

given
P=455
r=4%=0.04
n=1
t=2

$A=455(1+ \frac{0.04}{1})^{(2)(1)}$
$A=455(1+ 0.04)^{2}$
$A=455(1.04)^{2}$
A=492.128
round
$492.13
3rd option

Answer:

$90\pi$

Step-by-step explanation:

The first step is to find the slant height of the cone. Using the pythagorean theorem, you can find that $\sqrt{12^2+5^2}=13$ cm. Plugging this into the equation, you get $\pi \cdot 5 \cdot 13=90\pi$ . Hope this helps!
