Answer:
When we have a function f(x) = y.
The rate of change between a and b (where a < b) is:
R = (f(b) - f(a))/(b - a)
In this case:
b = 3
a = 1
f(3) = 127
f(1) = 95
R = (127 - 95)/(3 - 1) = 16
The rate of change in that interval is 16.
Answer:
20.
$18.40.
Step-by-step explanation:
The mean number of people = (12+19+17+26+26)/5
= 100/5
= 20.
Karmin's original hourly rate = 480/30
= $16 per hour.
With a 15% rise it is 16 * 1.15
= $18.40 / hour.
Let the angle be y;
Then the supplement is 5y
y+5y=180
6y=180
y=30
The angle is 30 degrees
Answer:
11 months
Step-by-step explanation:
185 - 20 = 165
165 ÷ 15 = 11
Answer:
