If the FDIC has an insurance fund of $67. 8 billion and must use 7. 6% of it to cover several failed banks, approximately how mu

Black_prince [1.1K]

The remaining money will be $62. 65 billion

<h3>What will be the remaining fund in FDIC?</h3>

Given amount =$67. 8 billion

Amount used to cover several failed banks = 7.6% of the total amount

So the amount used to cover several failed banks= $\dfrac{67.8\times 7.6}{100}$

$Amount = 5.1528$

So the remaining amount = $67.8-5.15=62.65$

Thus the remaining money will be $62. 65 billion

What is the sum of a geometric sequence 1, 3, 9, ... if there are 12 terms?

attashe74 [19]

We know that
a1=1
a2=3
a3=9
a2/a1=3/1----> 3
a3/a2=9/3----> 3
common ration r is equal to 3
number of terms n is 12

The Sum of geometric series is given by the formula
Sum=a1*[1-r^n]/[1-r]
Sum=1*[1-3^12]/[1-3]-----> Sum=[1-3^12]/[1-3]----> [3^12-1]/[3-1]
Sum=531440/2-----> 265720

the answer is
265720

Write the slope intercept form of the equation of the line through the given points. (5,-1) and (-5,2)

Lelu [443]

Answer:

$y=-\frac{3}{10} x+\frac{1}{2}$ or $-\frac{3}{10}$

Step-by-step explanation:

first use the y2-y1/x2-x1 formula then use y=mx+b after

plug in 2 for y2 and -1 for y1

plug in -5 for x2 and 5 for x1

$\frac{2-(-1)}{-5-5}$ =

2+1=3

-5-5=-10

$-\frac{3}{10}$ is ur slope

_____________________

this is the y=mx+b formula *extra info ig*

i usually use the first point for this but u can use watever point u want

plug in 5 for x

plug in -1 for y

and plug -3/10 for m

-1=-3/10(5)+b

-3/10*5=-3/2

-1=-3/2+b

add -3/2 on both sides

-1+3/2=1/2

1/2=b and b is ur y-intercept

y=-3/10x+1/2

hope this helps
