The surface of a mountain is modeled by the equation h(x, y) = 5000 - 0.001x² - 0.004y². A mountain climber is at the point (500, 300, 4390). In what direction should the climber move in order to ascend at the greatest rate?

Answers

Answer:

i-2.4j

Step-by-step explanation:

Given that,

The surface of a mountain is modeled by the equation as follows :

h(x,y)=5000 -0.001x^2-0.004y^2

A mountain climber is at the point (500, 300, 4390).

We need to find the direction in which he should move in order to ascend at the greatest rate.

To find direction, first finding the gradient of h as follows :

\nabla h(x,y)=-0.002xi-0.008yj

Now put x = 500 and y = 300

So,

\nabla h(x,y)=-0.002(500)i-0.008(300)j\n\n\nabla h(x,y)=i-2.4j

The direction of the climber is i-2.4j

How many degrees does the minute hand of a clock travel in 1 minute? What angle does an hour hand travel in 1 min?

Answers

Answer:

Step-by-step explanation:

The movement of the minute hand of the clock is circular. This means that a complete movement of the minute hand of the clock is the same as the angle formed at the center of the circle. The sum of the angles at a point is 360 degrees. The minute hand travels 360 degrees in a 60 minutes. It means that the degrees travelled in a minute is

360/60 = 6 degrees

The hour hand travels 360 degrees in 60 minutes. Therefore, the angle that the hour hand travels in 1 minute is

360/6 = 6 degrees

Final answer:

The minute hand of a clock travels 6° in 1 minute. The hour hand travels 0.5° in 1 minute.

Explanation:

To answer this question, we first need to consider what a full rotation is. A complete circle, one full rotation, is 360°. The minute hand of a clock completes one full rotation, or 360°, every hour or 60 minutes.

In 1 minute, the minute hand would have covered 1/60 of a full rotation. To calculate this in degrees, we multiply 360° by 1/60, which gives us 6°. Therefore, the minute hand of a clock travels 6° in one minute.

The hour hand moves more slowly. It takes 12 hours to complete a full rotation or 360°. In 1 minute, the hour hand covers, 360° divided by (12 hours x 60 minutes), which gives us 0.5°. Therefore, the hour hand of a clock moves 0.5° in 1 minute.

What are the x-intercepts of the parabola represented by the equation y = 3x2 + 6x − 10

Answers

Answer:

x ≈ {-3.082, 1.082}

Step-by-step explanation:

I find the easiest way to answer such a question (with medium accuracy) is to use a graphing calculator. The graph shown in the attachment gives the answers listed above.

___

From vertex form

The graphing calculator also makes it easy to find the vertex of the parabola. If we divide by 3 so the scale factor is 1, then the y-value of the vertex is -13/3 and the vertex form of the equation can be written ...

... y = (x +1)² -13/3

This has x-intercepts easily found.

... 0 = (x +1)² -13/3 . . . . x-intercepts are where y=0

... (x +1)² = 13/3 . . . . . . . add 13/3

... x +1 = ±√(13/3) . . . . . take the square root

... x = -1 ±√(13/3) . . . . . subtract 1

... x ≈ {-3.0816660, 1.0816660}

_____

Using the quadratic formula

This equation has a=3, b=6, c=-10, so we can put these values into the quadratic formula to find the x-interecepts.

... x = (-b±√(b²-4ac))/(2a)

... x = (-6 ±√(6² -4(3)(-10)))/(2(3))

... x = (-6 ±√156)/6 = -1 ±√(13/3) . . .  or . . . -1 ±(√39)/3
