Answer:
3 sips equal a gulp
Step-by-step explanation:
we have
----> equation A
Divide by 2 both sides
----> equation B
equate equation A and equation B
Group terms that contain the same variable

Answer:
x represents +50 for every hour. the inequality is y = 4x + 500 or y = x + 500.
they can ride it for 4 hours
Step-by-step explanation:
y(total cost) = x(50 per hour) + 500(y-intercept)
The answer is C, mean =100 and standard deviation=15
Answer: A.
B. A'(5) = 1.76 cm/s
Step-by-step explanation: <u>Rate</u> <u>of</u> <u>change</u> measures the slope of a curve at a certain instant, therefore, rate is the derivative.
A. Area of a circle is given by
So to find the rate of the area:
Using
Then
Multipying and simplifying:
The rate at which the area is increasing is given by expression .
B. At t = 5, rate is:
At 5 seconds, the area is expanded at a rate of 1.76 cm/s.
