Dixon is performing stunts for a show where he launches off from the edge of a ramp on his motorbike. The graph shown below trac

es the path of the bike while it is in the air, where y is the height of the bike above the ground and x is the horizontal distance from the edge of the ramp. Five stages of the bike's path through the air are marked on the graph below.
Select all the true statements about the graph.

The height of the bike changes more quickly at piece A than at piece B.
The height of the bike changes at the same rate throughout the entire path.
The height of the bike changes at the same rate at pieces A and B.
The height of the bike changes at the slowest rate at piece C.
The height of the bike changes at the same rate at pieces B and D.
The height of the bike changes more slowly at piece A than at piece D.

Answer:

Answer+Step-by-step explanation: 2019 game of the year award limited edition.

Step-by-step explanation:

This is all about carefully examining the slope. If you look carefully you will notice B curves in at the top just a little more than A so the first one is correct.

The second one is obviously not true.

The third one is disproved by the first.

The fourth one is correct as C is the peak and has little to no drop or rise.

The 5th one is correct, after spending several minutes examining it with 200%+ zoom I will tell you that it is correct B and D are the same.

I'm not 100% sure but I'm probably 95% sure that The 6th one is incorrect and A is changing height faster than D.

Use lagrange multipliers to find the points on the given surface that are closest to the origin. y2 = 64 + xz
Inessa [10]
The distance between an arbitrary point on the surface and the origin is

d(x,y,z)=\sqrt{x^2+y^2+z^2}

Recall that for differentiable functions g(x) and h(x), the composition g(h(x)) attains extrema at the same points that h(x) does, so we can consider an augmented distance function

D(x,y,z)=x^2+y^2+z^2

The Lagrangian would then be

L(x,y,z,\lambda)=x^2+y^2+z^2+\lambda(y^2-64-xz)

We have partial derivatives

\begin{cases}L_x=2x-\lambda z\\L_y=2y+2y\lambda\\L_z=2z-\lambda x\\L_\lambda=y^2-64-xz\end{cases}

Set each partial derivative to 0 and solve the system to find the critical points.

From the second equation it follows that either y=0 or \lambda=-1. In the first case we arrive at a contradiction (I'll leave establishing that to you). If \lambda=-1, then we have

\begin{cases}2x+z=0\\2z+x=0\end{cases}\implies x=0,z=0

This means y^2=64\implies y=\pm8

so that the points on the surface closest to the origin are (0,\pm8,0).

The average density of Styrofoam is 1.00 kg/m^3. If a Styrofoam cooler is made with outside dimensions of 50.0 x 35.0 x 30.0 cm
Nadusha1986 [10]

Answer:

View graph

Step-by-step explanation:

The closest by default to 1100 cubic inches is taking two side and two front covers and that would give you 1080.12 cubic inches since two of the covers you must subtract 3 cm per side and side which would add 6 cm in total so outside would be 35 cm and indoor 29 cm . According the graph

29*50*3= 4350 * 2 lid = 8700 cm3

30*50*3= 4500*2 lid = 9000 cm3

So 8700+9000 = 17700 cm3 to inches 3 = 1080.12 cm3

Barrett works at an ice cream shop. The function f(x) represents the amount of money PLEASE HELP!!!!!!!!!!!!!
oee [108]

Answer:

f(g(x))=6x^3+4, it is the amount of money earned per number of hours of work, x

Step-by-step explanation:

Here we have two functions:

f(x)=2x^2 +4

This function represents the amount of money (the earning) per unit x

Then we have the function

g(x)=\sqrt{3x^3}

which represents the number of gallons of ice cream that Barrett makes per hour, where x is the number of hours he works.

Here we want to find the composite function

f(g(x))

which means that we use the output of g(x) as input for f(x). In this context, this means that the function f(g(x)) represents the amount of money earned per number of hours of work, x.

Substituting g(x) into the x of f(x), we find:

f(g(x))=2(g(x))^2+4=2(\sqrt{3x^3})^2+4=2(3x^3)+4=6x^3+4

Amy, Rick, and Nisha are investing in three different types of stocks. What type of stock is each person Investing in?
GenaCL600 [577]

Answer: Amy = domestic stock

Rick = Employer stock

Nisha = International stock

Step-by-step explanation:

Amy invests in shares that won't be affected by exchange rate fluctuations. This shows that the stock that Amy invested in is a domestic stock. These are the stocks that are usually sold by companies in the home country.

As a part of Rick's full-time benefits package, he can invest in compally stock. This shows that Rick invested in the employer stock.

Nisha needs to research the political situation in a specific country before she purchases stock. Nisha invested in an international stock.
