Exercise 1. How fast does the level of the water contained in a cylindrical tank drop if we are emptying it at a rate of 3000 liters per minute?
Solution
Let r be the radius of the cylinder and h be the height measured in decimeters. Let V(t) be the volume of water, measured in liters (=dcm3), that is in the cylinder at time t measured in minutes. The information they give us is a variation rate
V(t + 1) − V(t) = −3000 liters per minute
In this type of exercise, the variation rate is interpreted as a derivative: V ′(t) = −3000. Notice that V(t + to) − V(to) u V′(to)t, so the interpretation is reasonable. The negative sign of the derivative is required since the volume decreases with time. Since the radius is constant but the height of the water depends on time, we have
and we deduce therefore
V(t) = πr2h(t)
V′(t) = −3000 = πr2h′(t)
h′(t) = −3000 decimeters per minute πr2
If we express the measurements in meters, then h ′ (t) = − 3 meters per minute. πr2
Exercise 2. A point P moves on the part of the parabola x = y 2 situated in the first quadrant in such a way that its x coordinate is increasing at a rate of 5 cm/sg. Find the speed at which point P recedes from the origin when x = 9.
Miguel Martín and Javier Pérez (University of Granada)
Solved exercises chapter 2 2 Solution
Let (x(t), y(t)) be the coordinates, measured in centimeters, of the point P at the instant t measured in seconds. They tell us that y(t) > 0 and that x(t) = y(t)2. The distance from point P to the origin is given by f (t) = px(t)2 + y(t)2 , so
′ x(t)x ′(t) + y(t)y ′(t) f (t) = px(t)2 + y(t)2
What we are asked for is f ′(to) knowing that x(to) = 9. In this case it must be y(to) = 3. We also know x′(t) = 5 (cm/sg). With this it is easy to deduce the value of y′(to) = x′(to) = 5. Finally,
2y(to) 6
′ x(to)x′(to)+y(to)y′(to) 45+3(5/6) 95
f (to)= px(to)2+y(to)2 = 81+9 =6√10 cm/s sorry is a lot

Order the numbers from closest to zero to farthest from zero:

HELPPPPP
Answers
The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.
With that being said, here is the order of the numbers from smallest to largest:
4.38
4.5
4.6

The value of x in the regular polygon is 15.4.
What is the value of x?
The value of x is calculated as follows;The sum of the interior angles of a polygon with n sides is given by the formula;(n-2) x 180
Since the regular polygon in question can be decomposed into 46 triangles, it has 46 x 3 = 138 sides.The value of each interior angle is calculated as;= (n - 2) x 180 / n = (138 - 2) x 180 / 138 = 169.6⁰9.5x + 26.2 = 169.69.5x = 143.4x = 15.1

Description by county:
Land areas won by Republicans is greater than those won by Democrats.
Description by state:
Democrat winner = approximately half
Republican winner = approximately half
The above means that

Answer:
The answer is The Democrats won the most electoral votes in the election.
The map showing the results by county shows that the Republicans won more land area, but the map showing the results by state shows that the Democrats won more states. The electoral college is made up of electors from each state, and the number of electors each state has is equal to the number of seats it has in Congress plus its two senators. The Democrats won more states in 2008, so they won more electoral votes and the election.

What is the scale factor?

3
Answers
Answer:
The result of this dilation is an enlargement. The scale factor is 3.
Step-by-step explanation:
The original figure has coordinates (0,0), (1,0), (2,0), (2,1), and (1,1). The dilated figure has coordinates (0,0), (3,0), (6,0), (6,3), and (3,3). Notice that the distances between corresponding points in the original and dilated figures are all multiples of 3. This means that the dilation has a scale factor of 3.
In general, a dilation is an enlargement if the scale factor is greater than 1, a reduction if the scale factor is less than 1, and a congruent image if the scale factor is equal to 1.

Answer:
105 square inches
Step-by-step explanation:
area of a triangle = 1/2( base * height)
The base is 5 and the height is 8.
= 1/2 ( 5 *8)
= 1/2(40)
= 20
The area of each triangle = 20 sq inches
So 4 triangles x 20 sq inches each = 80 sq inches.
The area of the square is 5 x 5 = 25 sq inches.
Add them together.
80 + 25 = 105 square inches
