Since 360 pennies are added to Susan's penny bank and it ends up as being 5/8 full, we need to find out how many pennies is equivalent to 8/8 (1, or full).

We already know that 360 equals 5/8 of Susan's penny bank, so divide 360 by 8.

360 / 8 = 45

Then, multiply 45 by 3 in order to find how many pennies is equivalent to 3/8 of the penny bank.

45 x 3 = 135

After that, add 360 to 135, which is theoretically the same as 5/8 + 3/8.

360 + 135 = 495

5/8 + 3/8 = 8/8 or 1

Therefore, Susan's penny bank can hold 495 pennies in total.






P.S. This may not be your preferred method of solving this problem, but this is certainly one of the ways of understanding them. -AM

if you deposit $8000 into an account paying 9% annual interest compunded semi anually how long will it take for your money to do
Anna007 [38]

Answer:

7.87 years

Step-by-step explanation:

#First we determine the effective annual rate based on the 9% compounded semi annual;

i_m=(1+i/m)^m-1\\\\=(1+0.09/2)^2-1\\\\=0.09203

#We then use this effective rate in the compound interest formula to solve for n. Given that the principal doubles after 2 yrs:

A=P(1+i)^n\\\\A=2P, i=i_m\\\\16000=8000(1.09203)^n\\\\2=1.09203^n\\\\n=\frac{log \ 2}{log \ 1.09203}\\\\=7.87324\approx7.87 \ yrs

Hence, it takes 7.87 years for the principal amount to double.

4. The following set of points belong to a specific function: {(-3,0)(-2,4), (-1,0 ), (0,-6),(1,-8), (2,0),(3,24)} Based on the
notsponge [240]

The type of function that these sets of points are known to produce is the cubic function.

<h3>What is a cubic function?</h3>

This is a function that is known to be a polynomial of degree 3. This type of polynomial is one that the coefficients are known to be complex numbers.

This is a cubic function given that the x axis is known to go through these points (-3,0), (-1,0), (2,0).

b. Given the sets of pints that we have, we have the equation

f(x) = a(x+3)(x+1)(x-2)

Such that

f = -2 =

4 = a x 1 x -1 x -4

4 = 4a

a = 1
