D. is the correct answer, as functions cannot have the same x value correspond to different y values. For a function to be considered a function, it must always pass the vertical line test.
Answer:
50.031 watts
Step-by-step explanation:
Formula
Power = Force * distance / time
The units are critical
distance = meters
time = seconds
force = newtons = kg * m / s^2
Solution
F = m * a
a = 9.81
m = 102 kg
F = 102 * 9.81 = 1000.62 Newtons
T = minute = 60 sec/min * 1 min
T = 60 seconds
d = 3 meters
Power = 1000.62 * 3 / 60
Power = 50.031
Hello!
Another way to put it would be scientific notation. to do so, you would need to get a digit 1-10 multiplied by 10 to a certain power.
For this problem, scientific notation is 1.67(10^16).
To check our answer, we will move the decimal to the right sixteen times because the exponent is positive. In other words, we will add fourteen zeros because we need two to turn 1.67 into 167. This gives us 16,700,000,000,000,000, which matches the question. (This number in word form is 16 quadrillion seven hundred trillion.)
Our final answer is 1.67(10^16).
I hope this helps!
The annual number of cases can be modeled using a quadratic equation y = 14x2 – 9x + 1. the variable x represents the number of years after 2008. the variable y represents the number of pertussis cases in year x. according to the equation, in what year can the county be expected to have 2,619 cases of pertussis?
