Answer:

\approx 9.0\:\mathrm{units}

Step-by-step explanation:

The magnitude of 3D vector \vec{v} can be given by the following:

| \overline{v}| =\sqrt{{v_x}^2+{v_y}^2+{v_z}^2}

Plugging in given values, we have:

| \overline{v}|=\sqrt{3^2+7.2^2+4.5^2},\\| \overline{v}| \approx \fbox{$9.0\:\mathrm{units}$}.

The vertical angle to the top of a flagpole from point A on the ground is observed to be 37°11'. The observer walks 17 m directl
inysia [295]

Answer:

22m

Step-by-step explanation:

Let height of flagpole=h

AB==17 m

\angle CAD=37^{\circ}11'=37+\frac{11}{60}=37.183^{\circ}(1 degree= 60 minute)

\angle B=25^{\circ}43'=25+\frac{43}{60}=25.72^{\circ}

We have to find the approximate height of the flagpole.

In triangle CDA,

\frac{CD}{DA}=tan\theta=\frac{Perpendicular\;side}{Base}

\frac{h}{DA}=tan37.183^{\circ}

h=DA(0.759)

In triangle CDB,

tan 25.72^{\circ}=\frac{CD}{DB}

0.482=\frac{h}{DA+17}

0.482DA+8.194=h

Substitute the value

0.482DA+8.194=0.759DA

8.194=0.759DA-0.482DA

8.194=0.277DA

DA=\frac{8.194}{0.277}=29.58

Substitute the value

h=29.58 \times 0.759=22.45 m\approx 22m

Hence, the height of the flagpole=22 m

gregorys nine chickens laid an average of six eggs each per week. gergory sold those eggs for $3 per dozen. how much did he coll
WARRIOR [948]
The answer is 27 dollars. 9 chickens X 6 eggs per chicken = 54. 54 eggs divided by 12 = 4.5 cartons (dozen) 4.5 x 3 = 13.5. That's in a week, so 2 weeks means you just multiply 13.5 X 2 which equals 27

Can someone please help me with this paper? (Instructions are in Project Part 5)
IRINA_888 [86]

Answer:

Step-by-step explanation:

IT can be easy to compromise your experience in graduate school or work because you’re trying to get the most you can out of both experiences at once. Especially since you’re essentially doubling the demands and responsibilities in your life for the duration of your degree. Working full-time while also studying full-time clearly requires a lot of effort. Putting so much of your mental and physical energy into this uneasy arrangement can quickly leave you feel.

The flexibility of your employer and your grad program are critical factors in your ability to balance the two endeavors. If your employer understands that you will have academic demands and your will sometimes require shifts in schedule or occasional personal days to deal with school-related obligations, it will make the prospect of studying that much easier. Similarly, finding a graduate program that can accommodate some of the requirements of your work life can make a big difference. That said, finding out that your boss won’t let you shuffle some work hours so that you can attend a 12:30 class twice a week is not something you want to discover after enrolling. It’s best to start talking with your managers about your graduate study plans early, while also researching schools that offer worker-friendly programs (evening or weekend classes, online courses or components, and part-time options). Even if class schedules appear to complement your work schedule, be cognizant of the scheduling issues that can arise from out-of-the-classroom requirements, such as field research, practical experience components, or group projects.  

Given the fatigue and stress involved with studying and working full-time, it’s important to recall your motivations for taking this approach, and to regularly evaluate your ability to continue at this pace. If you are really finding it too much to handle, remember that it’s usually possible to reduce your course load once you’ve started your studies and in consultation with your advisor and program director. Keep in mind that shifting the number of credit hours you take each term may also shift your eligibility for some financial aid and impact the time it takes to complete your degree.
