What is vertex of x^2+5x-3
Art [367]

\text{The vertex of}\ ax^2+bx+c:\\\\(h,\ k),\ \text{where}\ h=\dfrac{-b}{2a};\ k=f(h)=\dfrac{-(-b^2-4ac)}{4a}

\text{We have:}\\f(x)=x^2+5x-3\\\\a=1,\ b=5,\ c=-3\\\\h=\dfrac{-5}{2\cdot1}=\dfrac{-5}{2}=-2.5\\\\k=f(-2.5)=(-2.5)^2+5(-2.5)-3=6.25-12.5-3=-9.25

\text{Answer: the vertex is in}\ (-2.5;\ -9.25)

The formula
son4ous [18]

Answer:

The truck travel must to have a constant speed of 22.06\ ft/sec

Step-by-step explanation:

we have

d=1.3t^{2}+t+2

where

d expresses a car's distance in feet

t is the number of seconds

<em>Find the distance d for t=8 sec</em>

d=1.3(8)^{2}+8+2=93.2\ ft

<em>Find the distance d for t=8.2 sec</em>

d=1.3(8.2)^{2}+8.2+2=97.612\ ft

The total distance in this interval of 0.2 sec is

97.612-93.2=4.412\ ft

<em>Find the speed of the car</em>

Divide the total distance by the time

4.412/0.2=22.06\ ft/sec

therefore

The truck travel must to have a constant speed of 22.06\ ft/sec
