Hey there!!

How do we solve this?

We substitute the value of 0 instead of x

f ( 0 ) = - 7 ( 0 ) + 1

f(0) = 1

Hence, the required answer is 1

Hope my answer helps!!

F(x) is also y
So they said find x when y = 0

0= -7x + 1
Minus 1 from both sides

-1 = -7x

Divide-7 from both sides
X = 1/7

Find the sum of the infinite geometric series: 9 – 6 + 4 – …
balandron [24]
The defining characteristic of all geometric sequences is a common ratio which is a constant when dividing any term by the term preceding it.

In this case the common ratio is:  -6/9=4/-6=r=-2/3

An infinite series will have a sum when r^2<1, so in this case the sum will converge to an actual value because (-2/3)^(+oo) approaches zero.

The sum of any geometric sequence is:

s(n)=a(1-r^n)/(1-r), since we have a common ratio of -2/3 and we want to calculate an infinite series, ie, n approaches infinity, the sum becomes simply:

s(n)=a/(1-r)    (because (1-r^+oo) approaches 1 as n approaches +oo)

So our infinite sum is:

s(+oo)=9/(1--2/3)

s(+oo)=9/(1+2/3)

s(+oo)=9/(5/3)

s(+oo)=27/5

s(+oo)=54/10

s(+oo)=5.4

A bad contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 14% are pennies are 32% are dimes
Contact [7]

Answer:

$6.22

Step-by-step explanation:

Given;

Total number of coins N = 50

Number of pennies p = 14% of N = 0.14 × 50 = 7

Number of dimes d = 32% of N = 0.32×50 = 16

Number of nickels n = 4 + number of pennies = 4+p

n = 4+7 = 11

Number of quarters q;

N = p+d+n+q

q = N - (p+d+n)

q = 50-(7+16+11)

q = 16

1 Penny = 1 cent = $0.01

1 Nickel = 5 cent = $0.05

1 dime = 10 cents = $0.10

1 quarter = 25 cents = $0.25

Total amount in the bag is;

C = 0.01p + 0.05n + 0.10d +0.25q

Substituting the values;

C = 0.01(7) + 0.05(11) + 0.10(16) + 0.25(16)

C = $6.22

The bag contains $6.22
