Answer:
By putting x = -x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
Step-by-step explanation:
We need to explain why the function of
is neither even or odd
First we will understand, when the function is even and odd
Even function:
<em>A function is even if f(-x) = f(x) </em>
Odd function:
<em>A function is odd if f(-x) = -f(x) </em>
So, if we get the above result by putting x = -x, then we can say that the function is even or odd.
If we don't get any of the above results then the function is neither even nor odd.
So, for the given function: ![f(x)=4x^2+8x](https://tex.z-dn.net/?f=f%28x%29%3D4x%5E2%2B8x)
Put x = -x
![f(x)=4x^2+8x\\Put x=-x\\f(-x)=4(-x)^2+8(-x)\\f(-x)=4x^2-8x](https://tex.z-dn.net/?f=f%28x%29%3D4x%5E2%2B8x%5C%5CPut%20x%3D-x%5C%5Cf%28-x%29%3D4%28-x%29%5E2%2B8%28-x%29%5C%5Cf%28-x%29%3D4x%5E2-8x)
So, by putting x=-x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
Hello! :) So we know perimeter means around, right? So we would do 20 + 20 + 26 + 18 which equals 84. Finally 84 ft is our answer!
Hope it helps! :)
Answer:
Time taken to travel at 3 miles = 1.875
Time taken to travel at 5miles = 1.125
Total distance = 11.25
Step-by-step explanation:
D = speed x time
Time = distance/speed
Time at 3 miles per hour and 5 miles per hour
T1 = d/3
T2 = d/5
Total time = 3 hours
T1+t2 = 3 hours
d/3 + d/5 = 3
= d(1/2+1/5) = 3
d(5+3/15) = 3
d(8/15) = 3
We cross multiply
8d = 45
d = 45/8
= 5.625 miles
Total distance = 2d
2x5.625 = 11.25 miles
Since d is now known
T1 = 5.625/3 = 1.875 hours also 1 hour 52.5 minutes
T2 = 5.625/5 = 1.125 hours = 1 hour 7.5 minutes
Total distance 2xd = 11.25
Answer:
A
Step-by-step explanation:
it just is.
Answer:8:00
Step-by-step explanation:
You do 20+45 which =65 therefore there’s 60 min in a hour so it would be 7:00 then add the 5 mins =7:05 A.m , then you add 55+5 which =60 and add that to get 8:00
