Which equation represents the volume of a cone with the same base and height as the cylinder below?

Answers

Answer:

Volume of cone $V=(\pi.t^(2).k)/(3)$

Step-by-step explanation:

Since cone is having same base and height that means base of the cone is circular with radius t and height of the cone is k same of cylinder shown.

Now volume of a cone V = $(1)/(2)\pi .r^(2).h$

Since r = radius of the base of cone

h = height of the cone

Now we put the values of height and radius in the formula

$V=(\pi.t^(2).k)/(3)$

So the equation that represents the volume of cone is V = $(\pi.t^(2).k)/(3)$

check the picture below.

Solve each compound Inequality.42. -2 ≤ d + 1/2 < 4 1/2
44. 2t ≤ -4 or 7t ≥ 49
46. -1 ≤ a - 3 ≤ 2
48. A town's high temperature for a given month is 88 degrees Fahrenheit and the low temperature is 65 degrees Fahrenheit. Write a compound inequality to represent the range of temperatures for the given month.

Answers

42.
-2 ≤ d + 1/2 < 4 1/2 (-1/2)
-2 1/2 ≤ d ≤ 4

44.
2t ≤ -4 or 7t ≥ 49
2t ≤ -4 (/2)
t ≤ -2
7t ≥ 49 (/7)
t ≥ 7

46.
-1 ≤ a - 3 ≤ 2 (+3)
2 ≤ a ≤ 5

The key to solving these types of questions is to think to yourself - what do I need to do to get the variable on its own? Then, apply this action to every part of the inequality separated by inequality signs. When you get two separate inequalities describing the value of the variable, just think about them separately and apply the same logic.

All you have to do for the last question (48.) is turn the question into an inequality. Calling the temperature t:

65 ≤ t ≤ 88

Notice the use of greater-than-or-equal symbols - this is because 65 and 88 were recorded temperatures, so are included in the range of values for t

How can I find slope

Answers

To find the slope of a line, you first chooses 2 points with known coordinates that belongs to the line. Let those points be A(x1,y1) and B(x2,y2) with x2>x1.You then divide the subtraction of their Ys as y2-y1 by the subtractions of their Xs as x2-x1 (the point with the higher x comes first, this is why x2>x1). And let the slope be m.m= (y2-y1) / (x2-x1). If the slope is positive, the line croissant and y2>y1. If the slope is negative, the line is decroissant and y1>y2.Hope this helps! :)
