Step-by-step explanation:

<u>Step 1; Define</u>

<em>Identify</em>

f(x) = 5ˣ + 1

Interval <em>x</em> [0, 4] →<em>b</em> = 4, <em>a</em> = 0

<u>Step 2: Find Rate of Change</u>

  1. Substitute in variables [Average Rate of Change]:                                        \displaystyle \displaystyle \frac{f(4) - f(0)}{4 - 0}
  2. [Average Rate of Change] Substitute in <em>x</em> [Function f(x)]:                              \displaystyle \displaystyle \frac{(5^4 + 1) - (5^0 + 1)}{4 - 0}

You deposit $650 in a savings account. How long does it take an account with an annual interest rate of 5% to earn $178.25 in in
laiz [17]

Answer:

It takes an account 5.4 years  to earn $178.25 in interest with an annual interest rate of 5%.

Step-by-step explanation:

You can use the following formula to calculate the time it takes an account to earn a certain amount in interest:

t=(1/r)*((F/P)-1), where:

t= time

r= rate of interest= 5%

F= future value= 650+178.25=828.25

P= present value= 650

Now, you can replace the values on the formula:

t=(1/0.05)*((828.25/650)-1)

t=20*0.27

t=5.4

According to this, the answer is that it takes an account 5.4 years  to earn $178.25 in interest with an annual interest rate of 5%.

There are 4 generations. Daughter, mother, grandma, and great-grandma. The daughter is 44 less than the grandma's age. The great
Snezhnost [94]

Answer:

Age of Grandma = 59 years.

Age of great Grandma = 81 years

Ages of Mother = 38 years

Age of Daughter = 15 years

Step-by-step explanation:

Given:

Total years they all lived = 193

We need to find the ages of all lady.

Solution:

Let the age of grandma be 'x'.

Now Given:

The daughter is 44 less than the grandma's age.

So we can say that;

Age of the Daughter = x-44

The great-grandma is 22 more than the grandma's age.

So we can say that;

Age of the great grandma  = x+22

The mother is 80 less than twice the grandma's age.

So we can say that;

Age of the mother  = 2x-80

Now we can say that;

Total years they all lived  is equal to sum of age of grandma, Age of the Daughter, Age of the great grandma, Age of the mother.

framing in equation form we get;

x+x-44+x+22+2x-80=193\\\\5x-102=193

Adding both side by 102 we get;

5x-102+102=193+102\\\\5x= 295

Dividing both side by 5 we get;

\frac{5x}{5}=\frac{295}{5}\\\\x= 59\ years

Hence Age of Grandma = 59 years.

Age of great Grandma = x+22 =59+22 = 81\ years

Ages of Mother = 2x-80= 2\times 59-80 = 38\ years

Age of Daughter = x-44=59-44=15\ years
