Anna’s bank gives her a loan with a stated interest rate of 10.22%. How much greater will Anna’s effective interest rate be if t

nata0808 [166]

If the interest rate is compounded daily, we have the effective interest rate calculated as:
r = (1 + 0.1022/30)^30 -1
r = 0.1074 or 10.74%

Therefore, the effective interest rate if the compounded daily rather than monthly is 10.74-10.22 = 0.52 points higher.

The star aldebaran, visible from earth, lies about 65 light years away from us. What is the minimum amount of time that would be

makkiz [27]

A beam of light (travelling at the speed of light) would take 65 years to go and 65 years to come back from aldebaran, i.e. 130 years. You can send and receive a radio message (travelling at the speed of light, being electromagnetic radiation) taking so 130 years.

Explain why f(x)= 1/(x-x3)^3 is not continuous at x = 3.

Sloan [31]

Answer: Option b.

Step-by-step explanation:

1. You have the function $f(x)=\frac{1}{(x-3)^{3}}$ given in the problem above.

2. You must keep on mind that. by definition, the division by zero does not exist.

3. The value x=3 makes the denominator of the function f(x) equal to zero. Therefore you can conclude that the function shown in the problem is not defined at x=3.

The answer is the option b.

780 students stand in rows and columns. each row has an equal number of students and each column has an equal number of students

Alex73 [517]

Answer:

Step-by-step explanation:

x = number of rows

780=x(x+4)

$780=x^{2} +4x$

$x^{2} +4x-780=0\\(x+26)(x-30)=0\\x=30 \\x\neq -26\\$

there are 26 rows and 30 students in each row 26*30=780
