Answer:

<em>Spaghetti and Pizza are preferred almost equally.</em>

Step-by-step explanation:

Daniel surveyed a random sample of 100 students from his middle school to learn more about what type of school lunches are preferred based on his observation the table of the following is given as:

                        <u> Hamburgers  </u>           <u>Spaghetti </u>         <u> Pizza</u>

<u>Sample 1:</u>                 13                              43                     44

                      -----------------------------------------------------------------------

<u>Sample 2:</u>                20                              41                     39

                      -------------------------------------------------------------------------

<u> Total:</u>                       33                               84                   83

By looking at the table we see that the total number of spaghetti and Pizza chosen are almost equal as:

Total number of Spaghetti preferred=84.

and Total number of Pizza preferred=83.

Answer:

B. Time(length)

Step-by-step explanation:

The function that would be represented as a good name for a function for the length of the race and the return the time required to finished it

here the independent variable or the INPUT is the length while the output would be the time that required to finish it

Hence, the correct option is B,

Therefore all the other options would be incorrect

State the solutions for the quadratic equation depicted in the graph.
anzhelika [568]

Answer:

(-4,0), (-3,0)

Step-by-step explanation:

The solution of a quadratic equation is simply when the graph crosses the x-axis. This is because at that point, the function will equal 0.

From the graph, we can see that the graph touches the x-axis at x=-4 and x=-3.

Therefore, our solutions for the graphed quadratic is x=-4 and x=-3.

And we're done!

Find the work done by the force field F(x,y,z)=6xi+6yj+6k on a particle that moves along the helix r(t)=3 cos(t)i+3sin(t)j+2 tk,
kramer

Answer:

the work done by the force field = 24 π

Step-by-step explanation:

From the information given:

r(t) = 3 cos (t)i + 3 sin (t) j + 2 tk

= xi + yj + zk

∴

x = 3 cos (t)

y =  3 sin (t)

z = 2t

dr = (-3 sin (t)i + 3 cos (t) j + 2 k ) dt

Also F(x,y,z) = 6xi + 6yj + 6k

∴  F(t) = 18 cos (t) i + 18 sin (t) j +6 k

Workdone = 0 to 2π ∫ F(t) dr

\mathbf{= \int \limits ^{2 \pi} _{0} (18 cos (t) i + 18 sin (t) j +6k)(-3 sin (t)i+3cos (t) j +2k)\ dt}

\mathbf{= \int \limits ^{2 \pi} _{0} (-54 \ cos (t).sin(t) + 54 \ sin (t).cos (t) + 12 )    \ dt}

\mathbf{= \int \limits ^{2 \pi} _{0} 12    \ dt}

\mathbf{= 12 \times 2 \pi}

= 24 π
