Answer:
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount deposited.
P represents the principal or amount amount deposited
R represents interest rate
T represents the duration in years.
From the information given,
P = 560
R = 2%
T = 3 years
I = (560 × 2 × 3)/100 = $33.6
Therefore, the total amount that Mr. Caldwell will have in his account at the end of 3 years is
560 + 33.6 = $593.6
Answer:
3.5 seconds, B
Step-by-step explanation:
This is an upside down parabola, a function that is extremetly useful in helping us to understand position and velocity and time and how they are all related. Her upwards velocity is 16 ft/sec and she starts from a height of 140 feet, according to the problem. The h is the height she ends up at after a certain amount of time has gone by. You want to know how long it will take her to hit the water. When she hits the water, she has no more height. Therefore, her height above the water when she hits the water is 0. Plug in a 0 for h and factor the quadratic to get t = -2.5 seconds and t = 3.5 seconds. The only two things in math that will never ever be negative is a distance measure and time, so we can disregard the -2.5 and go with 3.5 seconds as our answer.
Function notation replaces the 'y' with a letter, usually 'f' and then puts the variable in parenthesis.
f(x) = 3x
Other equivalent examples would be:
g(x) = 3x
f(z) = 3z
h(a) = 3a
All of these represent the same function, just written in different forms of function notation. The variable can be represented as any letter and the function name can be different letters as well.
-x + 4 and that is the correct answer
