Find a1 if Sn = 89,800, r = 3.4, and n = 10. Round to the nearest hundredth if necessary.

xxMikexx [17]

Answer:

$a_1=1.04$

Step-by-step explanation:

We have a geometric sequence with:

$Sn = 89,800$ , $r = 3.4$ , and $n = 10$

Where

Sn is the sum of the sequence

r is the common ratio

$a_1$ is the first term in the sequence

n is the number of terms in the sequence

The formula to calculate the sum of a finite geometric sequence is:

$S_n=\frac{a_1(1-r^n)}{1-r}$

Then:

$89,800=\frac{a_1(1-(3.4)^{10})}{1-3.4}$

Now we solve for $a_1$

$89,800(1-3.4)=a_1(1-(3.4)^{10})$

$a_1=\frac{89,800(1-3.4)}{1-(3.4)^{10}}\\\\a_1=1.04$

Find the slope of the line that passes through (-5,-6), (-14,10)

Nostrana [21]

Answer:

$m=-\frac{4}{3}$

Step-by-step explanation:

Formula

$m=\frac{rise}{run}=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

Solve

$m=\frac{10+6}{-14+5}=\frac{16}{-9}=-\frac{4}{3}$

You can pay $10 for 2 movie tickets assuming the same rate , how much would you pay for 5 movie tickets ?

11Alexandr11 [23.1K]

Answer:

If we assume every 2 movie tickets is $10 then every one ticket would be $5. Assuming this to be true then 5 tickets is $25.

StepByStep Explanation:

movie tickets = t

2t=10

t=5

5t=?

5(5)=?

25=?

?=25
