A sum of money is deposited in a bank which offers a simple interest rate of 0.325% per annum. At the end of the 4 years, the total amount receives is $50 650. Find the sum of money deposited.

50.000

Step-by-step explanation:

the formula to get ther is the following:

X + ( X * * 4 ) = 50.650

X is the initial amount of money you need to find

4 are the years of interests

So, If you have interests, it means that some money will be added to yours. But how much?

The problem says that every year 0.325% of your initial amount will be added, so you will calculate that amount( X * ) and you multiply it by four.

All this added to your initial amount will be the final number you have 50.560

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
