$1 invested for 1 Year at 7.2% compound semiannually

1 answer:

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 )

y = - 4x + - 8 is equation of slope-intercept form.

What is in slope-intercept form?

Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.

the equation of slope - intercept form

y = mx + c

( -1 , -4 ) is point shown in graph

slope = -y/x

= - ( -4)/-1 = 4/-1 = -4

- 4 = -4 * - 1 + c

- 4 = 4 + c

c = - 4 - 4 = - 8

put value of c in the equation of slope - intercept form

y = - 4x + - 8
