I’m back!! I feel so embarrassed that I can’t answer it. Look- my brain died in a fire. plez help lol

You would have to pay back $448 in total after one year.

The simple interest formula can be expressed as;

I = P × r × t

Where I is interest, P is principal, r is interest rate and t is time.

Given the parameters:

Principal P = $400 (the initial loan amount)

Rate r = 12% = 12/100 = 0.12

Time t = 1 year

Interest = ?

To determine the interest, we can use the above formula for simple interest:

I = P × r × t

Interest = $400 × 0.12 × 1

Interest = $48

Money to be paid back will be:

Amount = Principal + Interest

Amount = $400 + $48

Amount = $448

Therefore, the accrued amount to be paid is $448.

Using exponential functions, the ending balances are given as follows:

1. $1,490.07.

2. $1,073.83.

3. $358.04.

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

Item a:

The parameters are:

A(0) = 939, r = 0.08, t = 6.

Hence the balance is:

[tex]A(6) = 939(1.08)^6 = 1490.07[/tex]

Item b:

The parameters are:

A(0) = 823, r = 0.03, t = 9.

Hence the balance is:

[tex]A(9) = 823(1.03)^9 = 1073.83[/tex]

Item c:

The parameters are:

A(0) = 269, r = 0.1, t = 3.

Hence the balance is:

9² or 9^2

Because the base is the same on the top and the bottom which is "9", you would either add or subtract the top and bottom exponent based on the arithmetic symbol used.

Because the arithmetic symbol division sign is used, you subtract the top exponent by the bottom giving you the answer nine to the power of two.

Answer:

The correct answer is [tex]9^2[/tex]

Step-by-step explanation:

9 is the base and 7-5=2. so n=2.

2a. -13

2b. 5

3. 8

Step-by-step explanation:

-5 to 8 is 13

-13 feet below cuz Below of number line

Answer:

Step-by-step explanation:

the answer is

$194 (start) / 100 (100%) = $1.94 (1%)

$1.94 * 7 = $13.58 (7%)

$13.58 * 13 (13 years) = $176.54

$194 (start) + $176.54 (interest) = $370.54

the interest on $194 at 7% interest rate for 13 years is approximately $176.54.

To find the interest on $194 at an annual interest rate of 7% for 13 years, we can use the formula for simple interest:

Interest = Principal * Rate * Time

Where:

Principal = $194 (initial amount)

Rate = 7% (convert to decimal: 7% = 0.07)

Time = 13 years

Now, plug in the values:

Interest = $194 * 0.07 * 13

Calculate the interest:

Interest = $194 * 0.91

Interest ≈ $176.54

So, the interest on $194 at 7% interest rate for 13 years is approximately $176.54.

Answer:

11/6 or 1 5/6yards

Step-by-step explanation:

Area = Length x Width

2 3/4 = 1 1/2 w

11/4 = 3/2w  to change 2 3/4  into an improper fraction see this as 2 wholes plus 3/4.  Another name for 2 wholes is 8/4 then add the 3/4.  8/4 + 3/4 is 11/4.

Do the same for 1 1/2 which is 1 + 1/2 change 1 into 2/2 and add it to 1/2 which would be 3/2.

Now solve for x

(2/3) (11/4) = (3/2) (2/3) w  when I multiply 3/2 by its reciprocal of 2/3, I get the number 1 and 1 times w is just w.

22/12 =w.  I just multiplies the tops with the bottoms.  Now, divide the top and the bottom by 2 and you end up with 11/6.  If I divide 11 by 6, it will go into 11 one time with 5 left over.  The denominator remains 6.

Answer:

Step-by-step explanation:

The area A of a rectangle of length L and width W is A = L*W.  Solving this for W, we get A/L.

Substituting 2 3/4 yd^2 for A and 1 1/2 yd for L, we get:

W = (2 3/4 yd)^2 / (1 1/2 yd)

This is equivalent to (11/4 yd^2 divided by (6/4 yd), or 11/6 yd.

Answer:

0.00998 Inches

Step-by-step explanation:

Thickness of the light bulb filament = 0.01 Inch

Allowable error = 2%.

2% of 0.01 = 0.02 X 0.01 =0.0002 Inch

Therefore, the allowable thickness of the bulb filament

We can then calculate the least allowable thickness of the filament as:

The least allowable thickness of the filament is 0.00998 Inches.

Answer:

C. 0.0098

Explanation:

one-hundredth of an inch: 1/100 ≈ 0.01 (inch)

Upper-bound (maximum error):

= 0.01 × (100% + 2%)

= 0.01 × 102%

= 0.0102 inches

Lower-bound (minimum error):

= 0.01 × (100% - 2%)

= 0.01 × 98%

= 0.0098 inches

Hence, the greatest allowable thickness of filament is 0.0102 inches and mostly the least allowable thickness is 0.0098 inches, which is the answer.

To remove the exponent from the v you need to square root both sides,

the exponent on the v is then canceled out giving you:

Answer:

Both C & D are correct

[tex]v^{2} =\frac{25}{81}[/tex]

Root both sides of the equation to remove the square.

[tex]v=\±\sqrt{\frac{25}{81} }[/tex]

Answer:

38 degrees

Step-by-step explanation:

Since angles KLO and OLM are supplementary, they add up to 180 degrees

So,  angle OLM is 180-134=46 degrees

Similarly, angles OMN and OML are supplementary, so they also add up to 180 degrees

So, angle OML is 180-84=96 degrees

You also know that the angles of a triangle sum up to 180 degrees

So, 46+96+x=180

180-142=38

Step-by-step explanation:

Answer:

Step-by-step explanation:

The equation y=7x+1 is written in slope intercept form. That would be:

y=mx+b

m is the slope

b is the y intercept, or where the line first is seen on the y axis.

Because b=1, the y intercept is 1.

Because m=7, the slope is 7.

STEP 1: GRAPH THE Y INTERCEPT.

Since b=1, the line crosses the y intercept when y=1. So graph y=1 on the coordinate plane.

STEP 2: GRAPH THE SLOPE

Do this by going up 7, then right 1. Because 7 is a positive number, you go up.
