Answer:

Option A) A = 100(1.005)^12t

Step-by-step explanation:

The formula for Total Amount obtained using compound interest is given as:

A = P( 1 + r/n) ^nt

Where

A = Total amount received or obtained after investing

P = Principal or Initial Amount invested

r = interest rate

n = rate or number of times the interest is compounded

t = time in years.

In the question we obtained this values

P = $100

r = 6% = 0.06

n = compounded monthly, we have 12 months in a year, hence, n = 12

t = t

Using the compound interest formula for Amount A,

A = P( 1 + r/n) ^nt

A = 100(1 + 0.06/12)^12 × t

A = 100(1 + 0.005)^12t

A = 100(1.005)^12t

Therefore, the value of Mari's Investment if the interest is compounded monthly is

A = 100(1.005)^12t

Hence, Option A is correct.

Prove that if d|m and d|n, then d|(m+n)

Mila [183]

$d\mid m$ means to say there is some $k_1$ such that $m=dk_1$ . Similarly, $d\mid n$ is equivalent to saying there exists $k_2[/te]x such that [tex]n=dk_2$ .

Now, $m+n=dk_1+dk_2=d(k_1+k_2)=dk_3$ , i.e. there is some $k_3$ such that $m+n$ is a multiple of $d$ , i.e. $d\mid(m+n)$ .

Godel is asked to perform the addition problem below. Godel believes that because there are more negative numbers, the answer wi

Answer:

$-7+12-3+9+(-5)=6$

Godbel is wrong in the reasoning as the answer does not depend on the number of negative numbers in the expression. Instead it depends on the value of the sum of positive terms and the value of the sum of negative terms. If the values of sum of positive terms is greater than the value of the sum of negative terms then the answer will be a positive and vice versa.

Step-by-step explanation:

Given expression:

$-7+12-3+9+(-5)$

To evaluate the expression.

Solution:

We have: $-7+12-3+9+(-5)$

Removing parenthesis first as a positive and negative multiply to give a negative.

⇒ $-7+12-3+9-5$

Then we can group the positives and negatives together.

⇒ $12+9-7-3-5$

⇒ $21-7-3-5$

Since the negatives combine by getting added up with the sum being negative, so we have:

⇒ $21-15$

As, we can see the positive value (21) is greater than the negative value (15) and hence the answer would be a positive.

⇒ 6

− 2/3 (x − 4) = − 4 thanks

ELEN [110]

Step 1: Simplify both sides of the equation.
-2/3x + 8/3 = -4

Step 2: Subtract 8/3 from both sides.

-2/3x+ 8/3 - 8/3 = -4-83
-2/3x = -20/3

Step 3: Multiply both sides by 3/(-2).

3/-2 x -2/3x = 3/-2 x -20/3
X = 10

All in all, x = 10
