Step-by-step explanation:
Y=2x²-x+4
1) we have to find the slope of this line.
we have to calculate the first derivative of this function.
y´=4x-1
The slope in x=3 will be: m(3)=4(3)-1=12-1=11.
2)We have to find a point of this line:
if x=3; ⇒y=2(3)²-3+4=18-3+4=19; Our point will be (3,19)
2) point-slope form: we need a point (x₀,y₀) and the slope.
y-y₀=m(x-x₀)
We know the slope (m=11) and the point (3,19); therefore:
y-19=11(x-3)
y=11x-33+19
y=11x-14
Answer: A. y=11x-14
You can simplify the fraction to get 2/5. If you convert this into a decimal you will get 0.4, so D is your answer.
350 miles/7 hours = 50 miles per hour
200 miles/ 3.75 hours =53 1/3 miles per hour
200 miles in 3.75 hours is faster
