$1 invested for 1 Year at 7.2% compound semiannually

Mathematics
1 answer:
WITCHER [35]3 years ago
7 0

Answer:

Sum = $1.073

Interest = $0.073

Step-by-step explanation:

Given that $1 is invested for one year at 7.2% interest which compounds semi-annually.

Semi-annual means there should be two equal intervals in a year i.e. 6 months interval.

Now, the semi-annual rate of interest is \frac{7.2}{2} = 3.6%.

Therefore, the invested money will become 1\times [1 + \frac{3.6}{100} ]^{2}  

= $1.073

Therefore, the interest obtained will be $(1.073 - 1) = $0.073. ( Answer )

Bryce tried to solve an equation step by step.
Aloiza [94]

$c=\frac{1}{3}

Solution:

Given equation is \frac{8}{3}=3c+\frac{5}{3}.

To solve the equation by step by step.

Step 1: Given

$\frac{8}{3}=3c+\frac{5}{3}$

Step 2: Combine like terms together.

Plus symbol changed to minus when the term goes from right to left (or) left to right of the equal sign.

$\frac{8}{3}-\frac{5}{3}=3c$

Step 3: Subtract the fractions in the left side.

$\frac{3}{3}=3c$

⇒ 1=3c$

Step 4: Divide both side of the equation by 3, we get

$\frac{1}{3} =\frac{3c}{3}$

$\frac{1}{3} =c$

Hence, the answer is c=\frac{1}{3}.

Find the common ratio for 0.1,0.01,0.001
yulyashka [42]

The common ratio of the set of data is 0. 1

<h3>How to determine the common ratio</h3>

To determine the common ratio of a set of data, we have to

  • Divide the second term by the first term or
  • Divide the third term by the second term

For the given set of data

0.1,0.01,0.001

Let's divide the second term by the first term

= 0. 01/ 0. 1

= 0. 1

Thus, the common ratio of the set of data is 0. 1
