Answer:
About 384.3 feet
Step-by-step explanation:
The formula for that is given by,
Where,
S is the speed of the car
d is the distance of skid
f is the drag factor for the road surface
n is breaking efficiency as percentage
Putting the values we get,
feet
So the length of skid marks would be 384.3 feet.
When you have f(3), that means X is equal to 3.
The problem states if x <-3 then f(x) would be -2.
If x is between -1 and -3, then f(x) would be 4x.
If x is greater than -1, f(x) would be x^2.
3 is greater then -1, so f(3) would be x^2, now replace x with 3 to get 3^2, which equals 9.
f(3) = 9
Answer:
f light is imagined as a flow of particles, the particles are called photons with each photon carrying a discrete packet of energy.
Answer:
x | y
10 1 = 1/2 (10) -4=5-5= 1
-2 -5 = 1/2(-2)-4=-1-4= -5
4 -2 = 1/2(4)-4=2-4= -2
-8 -8 = 1/2(-8)-4=-4-4= -8
