12.50h = 143.75 - 50

12.50h = 93.75

h = 93.75 / 12.50

h = 7.5 (or 7 1/2) hrs <====

Edwin deposited money into a savings account that pays a simple annual interest rate of 1.4%. He

mafiozo [28]

<h3>The deposited sum of money by Edwin is $350.</h3>

Step-by-step explanation:

Let us assume that the amount deposited = P

The rate of interest = 1.4%

The Simple Interest earned = $24.50

Time = T = 5 years

Now, as we know:

SIMPLE INTEREST = $\frac{P \times R \times T}{100}$

$\implies 24.50 = \frac{P \times 1.4 \times 5}{100} \\\implies P = \frac{24.50 \times 100}{1.4 \times 5} = 350\\\implies P = 350$

Hence, the deposited sum of money by Edwin is $350.

Write the first five terms of the sequence defined by the explicit formula an=-4n(n-1)

vladimir2022 [97]

The explicit formula of the sequence is given by a_n = -4n(n-1).

We have to find the first five terms of the sequence.

The first term:

$\begin{gathered} a_1=-4\times(1)(1-1) \\ =-4(0) \\ =0 \end{gathered}$

The second term:

$\begin{gathered} a_2=-4(2)(2-1) \\ =-8(1) \\ =-8 \end{gathered}$

The third sum:

$\begin{gathered} a_3=-4(3)(3-1) \\ =-12(2) \\ =-24 \end{gathered}$

The fourth term:

$\begin{gathered} a_4=-4(4)(4-1) \\ =-16(3) \\ =-48 \end{gathered}$

The fifth term:

$\begin{gathered} a_5=-4(5)(5-1) \\ =-20(4) \\ =-80 \end{gathered}$

Thus, option D is correct.
