hello,

" a turning point is defined as the point where a graph changes from either  increasing to decreasing, or  decreasing to increasing"

a)

y=x^3+x^2-6x\\\\y'=3x^2+2x-6=0\\x=\dfrac{-2-\sqrt{76} }{6} \approx{-1.786299647...}\\or\\x=\dfrac{-2+\sqrt{76} }{6} \approx{1.1196329...}\\

b)

Zeros are -3,0,2.

Sol={-3,0,2}

A train travels at 45 mph for 3 h and then increases its speed to 55 mph for 2 more hours. How far does the train travel in the
sammy [17]

Answer:

<h2> 245miles</h2>

Step-by-step explanation:

Step one:

given that the first 3 hours the train travels at a speed of 45 mph.

i.e Time = 3 hours

    speed =45 mph

    distance=?

we know that speed = distance/time

distance= speed*time

distance= 45*3

distance=135miles

Step two:

For the nex two hours it travels at 55 mph

i.e time= 2hours

   speed= 55mph

  distance=?

distance= speed*time

distance= 2*55

 distance= 110mile

Step three:

Hence for a total of 5 hours drive, the total distance covered is

135+110= 245miles

What is the distance in meter of an object that has an angular diameter of 30 arcseconds and a linear diameter of 10 cm?
Leya [2.2K]

Answer:

Distance of object = 0.0144 meter

Step-by-step explanation:

Given:

Angular diameter = 30 arcseconds = 30[100 / 3600]

Length of diameter = 10 cm

Find:

Distance of object

Computation:

Distance of object = [(2)(a)][TanФ / 2]

Distance of object = [(2)(10)][Tan(300 / 7200]

Distance of object = [20][Tan 0.04167]

Distance of object = [20][0.00072]]

Distance of object = 0.0144 meter
