Answer:

2x^2-17x+9

Step-by-step explanation:

Insert the two functions.

3x^2 -12x - (x^2 +5x -9)

Simplify.

3x^2 -12x -x^2 -5x +9

Combine like terms.

2x^2-17x+9

A particle is moving along the x-axis so that its position at t ≥ 0 is given by s(t) = (t)In(5t). Find the acceleration of the p
Anika [276]

position =  s(t) = (t)In(5t)

velocity = ds/dt =  t d/dt (ln (5t)) +d/dt (t) ln (5t)

              = t * 5 1/5t  + ln (5t)

          =  1 + ln (5t)

acceleration = dv/dt = d^2s/dt^2 = d/dt (1 + ln(5t))

                      =d/dt (1) + d/dt (ln 5t)

                        = 0 + 1/5t * 5

                       = 1/t

0 = 1 + ln (5t)

-1 = ln (5t)

e^-1 = 5t

1/e = 5t

1/(5e) =t

acceleration = 1/t = 1/(1/5e) = 5e

Answer: 5e

if a ball is thrown into the air with a velocity of 40 ft s its height in feet after t seconds is given by s(t)=40t-16t2 find th
dalvyx [7]

Answer with Step-by-step explanation:

We are given that a ball is thrown into the air with velocity

v=40ft/s

Height  after t seconds is given by

s(t)=40t-16t^2

We have to find the average velocity for the ball during the time [1,2].

We know that average velocity=\frac{ds}{dt}

Average velocity=v=\frac{d(40t-16t^2)}{dt}=40-32t

Substitute t=1 then we get

Average velocity=40-32(1)=40-32=8 m/s

Substitute t=2 then

Average velocity=40-32(2)=40-64

Average velocity[/tex]=-24 m/s[/tex]

What is the value of y?<br><br> a. 30<br> b. 26<br> c. 28<br> d. 24
Verizon [17]

Answer:

option-b

Step-by-step explanation:

we are given three parallel lines

so, corresponding angles must be equal

we get

126=5y-4

now, we can solve for y

Add both sides by 4

126+4=5y-4+4

130=5y

Divide both sides by 5

and we get

y=26...........Answer

How might the crisis in biodiversity lead to a food crisis for humans?
EleoNora [17]

Answer:

Hi and heres your answer!

Step-by-step explanation:

The crisis of biodiversity will lead to a food crisis for humans because:

1.No varieties in certain foods like plants and animals that are healthy

2.The Less food there is,more animals go extinct which means humans will go extinct too.

and finally 3: Without certain types of species like the bee, humans have no chance of survival (since bees pollinate flowers,fruits,and plants which could be used for human consumption and medicine)

Hope this helped

Dont forget smash that heart at the bottom <3

Have a great day,Youre amazing!
