Answer: Yes, you can tell how to model real life relationships. For example, a linear function is written at y=mx+b. Y is the total value, b is initial value, and m is the slope of the function.
Step-by-step explanation:
Real life example:
Your school needs to raise money. To do this, they host a school dance! The admission is $5 (initial cost, b), plus an additional $3 dollars for drinks. 3 would be the slope per drink, so this can be represented by y=3x+5!
Its 4 easy Thank me later
The area of a circle = pi * radius squared. so if the area = 136.45, start by dividing by pi to get about 43.43. this means the radius squared = 43.43. square root both sides to get about 6.59 = radius of the circle. the circumference can be found by multiplying the diameter * pi. since the diameter = the radius * 2, we know the diameter of the circle is 13.18. multiply by pi to find the circumference, which would be about 41.41.
Answer:
$91
Step-by-step explanation:
f(x) = 2.5 x
$25 more would + $25 to the function
60% = .6
Revenue is f(x) = 2.5x which we have to multiply by the .6
g(x) = $25 + .6 (2.5 x)
If we have 44 watermelons then we plug in 44 for x
x = 44
g(x) = $25 + .6 (2.5*44)
g(x) = $25 + .6 (110)
g(x) = 25 + 66
g(x) = $91
The profit is $91
