The mistake Pedro made was he said 19 goes into 146 6 times instead of 7.

Explanation: 526/19
19 goes into 52 twice, 52-38 is 14, bring down the 6, 146. 19 goes into 146 7 times, 146-133 is 13, giving you an answer of 27 R 13

Create an exponential to describe $100 at 2% interest, compounded annually, for x years. y=100(.98)^x y=100(.8)^x y=100(1.2)^x y

zysi [14]

The exponential to describe $100 at 2% interest, compounded annually, for x years is $y=100(1.02)^{x}$

<h3>Solution:</h3>

Given that $ 100 at 2 % interest , compounded annually for "x" years

The formula for compound interest, including principal sum, is:

$A=P\left(1+\frac{r}{n}\right)^{n t}$

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per unit t

t = the time the money is invested or borrowed for

Here in this sum,

P = $ 100

$r = 2 \% = \frac{2}{100} = 0.02$

number of years = x

Here given that compounded annually , so n = 1

Let "y" be the amount after "x" years

Substituting the values in formula we get,

$\begin{aligned}&y=100\left(1+\frac{0.02}{1}\right)^{1 \times x}\\\\&y=100(1+0.02)^{x}\\\\&y=100(1.02)^{x}\end{aligned}$

Thus the exponential to describe is $y=100(1.02)^{x}$

levacccp [35]

Answer:

2815 views

Step-by-step explanation:

Given :

⇒ Views on first day = 500

⇒ Rate of increase = 28%

============================================================

Creating a function :

⇒ Let y be the total number of views and x be the number of days since posted

⇒ y = 500 (1 + 0.28)ˣ = y = 500(1.28)ˣ

============================================================

Solving :

⇒ y = 500(1.28)⁷

⇒ y = 500(5.62949953)

⇒ y = 2815 views (nearest whole number)
