Which equation best describes the pattern in the table below?

1 answer:

7 0

First find the slope, (y2-y1)/(x2-x1)=(20-10)/(40-20)=10/20=1/2

y=mx+b, where m is the slope and b is the y-intercept

y=x/2+b, using any point we can solve for b, I'll use (20, 10)

10=20/2+b

10=10+b

0=b, so the cost function is:

C(m)=m/2 (cost in dollars as a function of minutes is minutes divided by two)

· The volume of a box in the shape of a cube<br>is 2197 cm3. Find the area of one side of the box.

Yuliya22 [10]

Answer:

Let the side of the cube be x.

Volume = length × width × height

For a cube:

Length = width = height

Now volume = x × x × x = x³

This equals 2197

Therefore :

X³ = 2197

X = ∛2197

= 13

The side of the cube = 13cm

Area = length × width

Length = width = 13cm

Area = 13 × 13 = 169

= 169 cm²

I hope this helps!

6. An airplane is taking off headed due north with an air speed of 173 miles per hour at an angle of 18° relative to the horizon

exis [7]

Answer: The answer is $u$ $plane$ 30.72 $i$ + 193. 18 $j$ + 53. 46 $k .$

Step-by-step explanation:

Component of the plane's velocity in the direction of vector relative to the air: ;

Component of the plane's velocity in the direction of vector relative to the air: .

The direction of the plane's velocity relative to the air is normal to vector . Therefore, the component of the plane's velocity (relative to the air) in that direction will equal zero. Thus

Refer to the second diagram,

Component of the velocity of the wind in the direction of vector : ;

Component of the velocity of the wind in the direction of vector : .

Assume that the wind blows horizontally. The direction of the wind will be normal to vector . The component of the velocity of the wind in the direction of vector will thus equal zero. Therefore,

The ground speed of the plane is the sum of and .

That is:
