Answer:
-55
Step-by-step explanation:
The answer is f(x) = 75, g(x) = 5x, h(x) = 5x + 75
Let x be the number of lessons.
The <u>flat rate of $75</u> as function f(x) can be expressed as: f(x) = <u>75</u>
<u>$5.00 per lesson x</u> as function g(x) can be expressed as: g(x) = <u>5x
</u>
The combination of two functions (f(x) and g(x)) is the amount the parent should pay:
h(x) = g(x) + f(x)
h(x) = 5x + 75
Answer:
87.92 ft
Step-by-step explanation:
The circumference of a circle can be found using the formula: c = 2pi(r) OR c = pi(d).
r stands for the radius, d stands for the diameter. Because you're given the diameter of the circle, you can simply multiply 28 by pi (3.14), and you'll get the circumference!
