The domain is the input or x value in the coordinate and the range is the output or y value of the coordinate.

Wewaii [24]

I think it’s 15 percent

2/20=10/100
1/20=5/100
10+5=15

Which division problem does the number line below best illustrate? A number line going from 0 to 13. An arrow jumps from 0 to 3,

Brums [2.3K]

Without the screenshot, it's fairly difficult to know what your teacher wants exactly. I found this similar problem

brainly.com/question/13583475

which might help. It sounds like you have 4 semicircles which can be thought of as a division problem 12/3 = 4. Note how I'm dividing by 3 which is the width of each section (eg: from 6 to 9 is 9-6 = 3 units)

Three forces act on a hook. Determine the magnitude of the resultant of the force.

Novay_Z [31]

Use Hooke's law... (just kidding)

Break down each force vector into horizontal and vertical components.

$\vec F_1=(1000\,\mathrm N)(\cos30^\circ\,\vec x+\sin30^\circ\,\vec y)\approx(866.025\,\mathrm N)\,\vec x+(500\,\mathrm N)\,\vec y$

$\vec F_2=(1500\,\mathrm N)(\cos160^\circ\,\vec x+\sin160^\circ\,\vec y)\approx(-1409.54\,\mathrm N)\,\vec x+(513.03\,\mathrm N)\,\vec y$

$\vec F_3=(750\,\mathrm N)(\cos195^\circ\,\vec x+\sin195^\circ\,\vec y)\approx(-724.444\,\mathrm N)\,\vec x+(-194.114\,\mathrm N)\,\vec y$

The resultant force is the sum of these vectors,

$\vec F=\displaystyle\sum_{i=1}^3\vec F_i\approx(-1267.96\,\mathrm N)\,\vec x+(818.916\,\mathrm N)\,\vec y$

and has magnitude

$|\vec F|\approx\sqrt{(-1267.96\,\mathrm N)^2+(818.916\,\mathrm N)^2}\approx1509.42\,\mathrm N$

The closest answer is D.

A city is 7,642 feet above sea level. Is this elevation closer to the highest point or the lowest point?

tekilochka [14]

Answer:

It must be closer to the lowest point.

Step-by-step explanation:

There is a simple and a general explanation to it. As it gets higher up from the sea level, the elevation gets closer to the lowest point simply because the distance from the highest point keeps decreasing as you get closer. The elevation is the distance left between the highest point and the current point.
