However (7^3)^-2 would equal to 343^-2 which would equal to 1/117649 or 8.49985 * 10^-6.

If you break it down more:

Answer:

(a) The closet to the simple interest eaened in 5 years is $275.00.

(b) The closet to the compound interest earned in 5 years is $276.28.

Step-by-step explanation:

These can be determine as follows:

(a) Simple Interest

The interest earned and be determined using the simple interest formula as follows:

Simple interest = P * R * T ....................... (1)

Where;

P = Principal = $1,000

R = interest rate = 5.5%

T = term = 5

Substituting the values into equation (1), we have:

Simple interest = $1,000 * 5.5% * 5 = $275.00

(b) Compound Interest

The interest earned and be determined using the compound interest formula as follows:

Compound interest = P(1 + R)^T - P ....................... (2)

Where;

P = Principal = $1,000

R = interest rate = 5%, or 0.05

T = term = 5

Substituting the values into equation (2), we have:

Compound interest = $1,000(1 + 0.05)^5 - $1,000 = ($1,000 * 1.05^5) - $1,000 = ($1,000 * 1.2762815625) - $1,000 =$1,276.28 - $1,000 = $276.28

Interest earned in savings Account 1 = 275

Interest earned in savings Account 2= 276.282

Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period.

interest earned by savings account 1

I₁=P*R*T/100

where,

P= Principal

R= rate of simple interest

T = time

I₁=1000*5.5*5/100

compound interest I₁=275

Interest earned by savings account2

amount A after n years= [tex]P(1+\frac{r}{100} )^n[/tex]

where,

A= amount received after 5 years

P= principal

r = rate(compound annually)

n = time

[tex]A = 1000(1+\frac{5}{100} )^5\\\\A=1276.282[/tex]

Compound interest I₂ = 1276.282-1000=276.282

Therefore,

interest earned in savings Account 1 = 275

interest earned in savings Account 2= 276.282

Answer:

a)Write the equation.

y = 40x + 75

b) What is the slope and y-intercept?

The slope = 40

y - Intercept = 75

Step-by-step explanation:

On a two week job a repairman works a total of 70 hours. He charges 75$ plus 40$ per hour.

The equation shows this realationship where x is the number of hours and y is the total fee is given using the equation of a straight line which is given as:

y = mx + c

Where m = Slope

c = y intercept

Applying this equation to our question , we have:

y= 40x + 75

The slope = m = 40

y-intercept = c = 75

Answer:

75 y intercept.

Step-by-step explanation:

Given that :

The United States has about 100,300,000 registered to use cellular phones in the year 2000

100,300,000 in scientific notation:

(100,000,000) + (300,000)

(1 * 10^8) + (3 * 10^5)

To ensure equal power :

300,000 = 3 * 10^5 = 0.003 * 10^8

Answer:

9.5 in

Step-by-step explanation:

The receiver is placed at the focus of the parabola at a distance of 1/4a from the vertex. Here that would be 1/(4*(1/38)) or 38/4 inches or 9.5 in

The receiver lies 9.5 inches far from the vertex of the cross-section.

Given that,
The cross-section (with units in inches) of a parabolic satellite dish can be modeled by the equation y=1/38 x².
To determine how far is the receiver from the vertex of the cross-section.

A parabola is a cross-section cut out of the cone and represented by an equation, y =4ax².

Here,
The receiver is located near the parabola's focus, 1/4a away from the vertex. That would be 1/(4×(1/38)) or 38/4 inches or 9.5 in. in this case.

Thus, the receiver lies 9.5 inches far from the vertex of the cross-section.

Answer:

This question is incomplete as it lacks the actual question. The question describes how Joe solved a system of equations step-by-step using elimination method. The steps used by Joe are as follows:

1. The equations given are: 2x + y = 9 and 3x - 2y = 10.

2. Multiply the first equation by 3 to get 6x + 3y = 27

3. Multiply the second equation by -2 to get -6x - 4y = -20

4. Add the equations to get -y = 7

5. Divide both sides of the equation by -1 to get y = -7

The statement that correctly identifies the mistake Joe made is: In step 3, Joe multiplied the term -2y by 2 instead of by-2.​

Step-by-step explanation:

Elimination method of solving a simultaneous equation in Mathematics involves removing one variable in order to solve another variable. In this case of equations:

2x + y = 9

3x - 2y = 10

Joe eliminates the x variable in order to solve for the y variable first. To do this;

- In step 2, he correctly multiplies the first equation by 3 to get 6x + 3y = 27

- In step 3, he multiplies the second equation by -2 to INCORRECTLY get -6x - 4y = -20

Joe made a mistake in this step 3 because he multiplied -2y in the original equation (3x - 2y = 10) by 2 and not -2. He should have gotten -6x + 4y = -20 if he multiplied by (-2). That is (-2 × -2y) to give +4y.

Answer:

Înălțimea bazinului este de 20 m

Step-by-step explanation:

Raza de bază a bazinului cilindric = lățimea peretelui dreptunghiular = 15 m

Suprafața peretelui dreptunghiular = lungime × lățime = 300 m²

300 m² = lungime × 15 m

lungime = 300 m² / 15m

lungime = 20 m

Lungimea peretelui dreptunghiular = înălțimea bazinului cilindric = 20 m

Prin urmare, înălțimea bazinului = 20 m.

The weight of the sea water in the aquarium is 3827.119 lb

Step-by-step explanation:

We start by calculating the volume of the aquarium

Since it is a cuboid, the volume will be L * B * H

= 4.4 * 2.5 * 5.3 = 58.3 ft^3

Mathematically;

Mass = density * volume

The density of sea water is 63.93 lb/ft^3

Mass = 63,93 * 58.3 = 3,827.119 lb

Answer:

n = (123 - 3a) / 0.1

Step-by-step explanation:

Given:

3a + 0.1n = 123

Solve for n

3a + 0.1n = 123

Subtract 3a from both sides

3a + 0.1n - 3a = 123 - 3a

0.1n = 123 - 3a

Divide both sides by 0.1

n = (123 - 3a) / 0.1

The resulting equation if 3a + 0.1n = 123 is solved for n is n = (123 - 3a) / 0.1

Answer: 2.8 minutes

Step-by-step explanation:

If it takes 12.5 gallons per minutes to fill the reservoir, then we have to divide 35 and 12.5.

35 ÷ 12.5 = 2.8 minutes

Since it takes 12.5 gallons per minutes to fill the reservoir, it will take 2.8 minutes to fill the reservoir.
