Answer:

-3/500, Celsius per meter

Step-by-step explanation:

Slope: $\frac{y_{2} - y_{1} }{x_{2}-x_{1} }$

Slope = 25-13/ 200-2200= -12/2000= -3/500

Rate of change. Celsius per meters (?) I'm not sure about that.

A cylinder is filled with 900 liters of water.find the area of its base if height of cylinder is 20dm.

Lisa [10]

The formula of the volume of a cylinder:

$V=\pi r^2H\\\\where:\\\\r-a\ radius\\H-a\ height\\\pi r^2-an\ area\ of\ base$

We have:

$V=900\ liters\\1L=1dm^3\ therefore\ V=900L=900dm^3$

and

$H=20\ dm$

substitute:

$\pi r^2\cdot20=900\ \ \ |:20\\\\\pi r^2=45\ dm^2$

Answer: The area of a base of the cylinder is equal 45 dm².

Zepler [3.9K]

The tangent function gives the ratio of vertical to horizontal distance in this case.
.. vertical distance = (horizontal distance)*tan(angle of depression)
.. = (40 m)*tan(50°)
.. vertical distance ≈ 47.7 m

Each calendar will sell for 5 each. Write an equation to model the total income, y, for selling x calendars

OleMash [197]

Answer:

y = 5x

Step-by-step explanation:

If each calendar, <em>x</em>, sells for $5 each, you would multiply 5·x because $5 is how much you earn per calender. Therefore, your total income would be 5 times the number of calendars you sell, or in equation "language", y = 5x
