This is middle school work woah
First you can convert 45 miles per hour to feet per hour:
45 × 5,280 = 237,600 feet per hour
Now you must remember that there are 60 minutes in an hour, and 60 seconds in a minute. So you can divide 237,600 feet per hour by 60 to get feet per minute:
237,600 ÷ 60 = 3,960 feet per minute
Now you just have to divide 3,960 by 60 again to get feet per second:
3,960 ÷ 60 = 66 feet per second
Now you know how fast the car can travel (in feet) in a second. So to work out how many feet it travels in 3 seconds, you just have to multiply 66 by 3:
66 × 3 = 198 feet
Therefore your final answer is <em>198 feet</em> :)
The average rate of change for a function over an interval is the slope
<h3>How to explain the steps?</h3>
Take for instance, we have the function to be
Function f(x)
And the interval is (a,b)
The average rate of change for the function over the interval is
Rate = (f(b) - f(a))/(b - a)
The above represents the slope
Take for instance, we have:
f(x) = x^2 [2, 4]
We have:
f(2) = 2^2 = 4
f(4) = 4^2 = 16
So, we have:
Rate = (16 - 4)/(4 - 2)
Rate = 6

Answer:
9a-65
Step-by-step explanation:
simply write 9a+(add the remaining numbers all together)
It would probably be 1 real zero and 2 complex zeros.
