Answer:

16.52%

Step-by-step explanation:

The effective interest rate is the real interest rate you have to pay on a loan when the compounding effect is considered. The formula to calculate it is:

Effective annual interest rate= (1+ $\frac{i}{n}$ )^n-1

i= interest rate: 15.3%

n= number of compounding periods: 365 as it is compounded daily and a year has 365 days.

Effective annual interest rate= (1+(0.153/365))^365-1

Effective annual interest rate= 0.1652→16.52%

According to this, the effective interest rate is 16.52%.

Finally, suppose m1→∞, while m2 remains finite. what value does the the magnitude of the tension approach?

Anna007 [38]

The answer is not infinity.
Consider FBDs of each mass with the direction of motion of m1 as positive 

m1*g-T=m1*a 

T-m2*g=m2*a 

assuming mass less cord and mass less, friction less pulley 
the accelerations are equal 
a=(T-m2*g)/m2 

m1*g-T=m1*(T-m2*g)/m2 
do some algebra 
m1*g-T=m1*T/m2-m1*g 
2*m1*g=T*(1+m1/m2) 
2*m1*m2*g=T*(m2+m1) 
2*m1*m2*g/(m2+m1)=T 
now take the limit of T as m1->infinity 
T=2*m2*g 

this is intuitively correct since the maximum acceleration of m1 is -g, the cord transfers the acceleration to m2, which is being acted on by gravity downward and an upward acceleration of g. Therefore the maximum acceleration of m1 is 2*g upward.

What is an equation of the line that passes through the points (-2, -5)and (-1, 1)?

suter [353]

First find the slope(m)

Slope= y2-y1/x2-x1= (1-(-5))/(-1-(-2))= 6/1 = 6

Then find the y intercept (move up six and right one from (-1, 1) to get (0, 7)

The y-intercept is y=7

Now make the equation

Y= slope(x) + y-intercept

Y=6x+7

Calculate the population variance of a population with data of {-3, - 5, 8, 11, 13}.

Mashutka [201]

Answer:

Step-by-step explanation:

First find the airithmatic mean

(-3-5+8+11+13)/5= 4.8

$\frac{(-3-4.8)^2+(-5-4.8)^2+(8-4.8)^2+(11-4.8)^2+(13-4.8)^2}{5}= 54.56$
