      I = Prnwhere I is the interest, P is the principal, r is the decimal equivalent of the given rate, and n  is the number of years. In this item, we assume that n is equal to 1. Solving for the interests,                $200:     I = ($200)(0.03)(1) = $6                $150:     I = ($150)(0.03)(1) = $4.5The difference between the two calculated interests is $1.5. 
Therefore, you could have earned $1.5 more if you invested $200 rather than $150. 
hope this helps (^>^)

Find the approximate value of each trigonometric function.
vodka [1.7K]

Answer:

<u>Given</u>

  • tanθ = 3.454
  • θ is in the III quadrant

We know in the III quadrant both sine and cosine are negative.

<u>Use the following identities to get values of sinθ and cos θ</u>

  • sinθ = - tanθ/√(1 +tan²θ)
  • cosθ = - 1/√(1 +tan²θ)

<u>Substitute the value of tanθ and find sine and cosine:</u>

  • sinθ = - 3.454/√(1 + 3.454²) = - 0.961
  • cosθ = - 1/√(1 + 3.454²) = - 0.278

Consider a system of two linear equations in two variables. If the graphs of the equations are not the same line, is it possible
FinnZ [79.3K]

Answer:

No

Step-by-step explanation:

Solutions to systems of equations are points at which the lines of the equations intersect. Knowing this, only equations representing the same line would have infinitely many solutions because they would intersect at every one of each other's points - they're the exact same line. Therefore, if they are not the same line, they would not intersect at each and every point, and would not have infinitely many solutions.

What is the balance after 15 years in a savings account that earns 2% interest compounded bimonthly when the initial deposit is
motikmotik

The amount will be equal to $1348.07. The correct option is A.

<h3>What is compound interest?</h3>

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

\rm A = P(1+\dfrac{r}{n})^{nt}

Compound Interest Formula:

A = Account Balance

P = Principle/Initial Amount

r = Rate of Interest (decimal)

n = Number of times compounded (per year)

t = Number of Years

Given Information

Account Balance = ?

It is given that the balance after 15 years in a savings account earns 2% interest compounded bi-monthly when the initial deposit is 1000.

This is because we are gaining money, so the multiplier should be greater than 1. We already added 1, which is 100% so you simply add the 0.02 for the extra 2%.

Number of times compounded per year = 6

This is because it is being compounded bi-monthly, or once every 2 months. 12 months divided by 2 months is 6 months, so 6 times a year.

Number of years = 15

Solve by plugging the given values into the formula.

\rm A = P(1+\dfrac{r}{n})^{nt}

\rm A = 1000(1+\dfrac{0.02}{6})^{6 \times 15}

A = 1000 x (1.14)

A = $1348.07.

Therefore, the amount will be equal to $1348.07. The correct option is A.
