The solution to the piecewise problem given are :

Difference in cost of 2 and 3 line ad is 0
Cost of 10-line ad = $108
Cost of 11 - line ad = $117

From the piecewice function given :

x = number of lines in ad

The cost of ad when x ≤ 3 is 45

Hence, the cost of a 2 and 3 line ad is 45, Therefore, the difference is 0 ;

The cost of a 10 - line ad ;

x = 10

Cost = 45 + 9(x - 3)

Cost = 45 + 9(10 - 3)

Cost = 45 + 9(7)

Cost = 45 + 63 = 108

The cost of a 11 - line ad ;

x = 11

Cost = 45 + 9(x - 3)

Cost = 45 + 9(11 - 3)

Cost = 45 + 9(8)

Cost = 45 + 72 = 117

Hence, the solution to the piecewise related questions.

A granite monument has a volume of 25,365.4 cm3. The density of granite is 2.7 g/cm3. Use this information to calculate the mass

kiruha [24]

V = 25,364.4 cm^3 Is volume
r = 2.7g/cm^3 Is density

To calculate mass you use formula:
m= V*r
To avoid remembering this formula you can see the type of unit on each given variable. We can see that we have g/cm^3 and cm^3. If we multiply them, we negate cm^3 and cm^3 and we are left with g which is unit for mass.

m = 68,486,6 g is the answer.

Given the points P(2,-1) and Q(-9,-6), what are the coordinates of the point on directed line segment PQ that partitions PQ in t

gayaneshka [121]

ANSWER

$( - \frac{23}{5} , - 4)$

EXPLANATION

Given the points P(2,-1) and Q(-9,-6),the coordinates of the point that partition the directed line segment PQ in the ratio 3:2 is given by

$x = \frac{ mx_2+nx_1}{m + n}$

$y= \frac{ my_2+ny_1}{m + n}$

Where m=3 and n=2

$x = \frac{ 3 ( - 9)+2(2)}{3+ 2}$

$x = \frac{ - 23}{5}$

$y= \frac{ 3( - 6)+2( - 1)}{3 + 2}$

$y= \frac{ - 20}{5} = - 4$

The point is

$( - \frac{23}{5} , - 4)$

(a) How is the number e defined? e is the number such that lim h → 0 e−h − 1 h = 1. e is the number such that lim h → 0 eh − 1 h

Fed [463]

Answer:

is the number such that lim h → [infinity] eh + 1 h = 1.

Step-by-step explanation:

The number e is known as the Euler's constant or Euler's number. The number basically is a mathematical expression that is equal to the rational number 2.71828. In addition, it is also the base of the natural logarithm or the Naperian logarithms. It is the number that the natural logarithm is equal to one. In addition, it is the limit of :

$\lim_{n \to \infty} (1 + \frac{1}{n })^{n}$

as n approaches infinity.

The expression is calculated as a sum of the infinite series

e = $\frac{1}{1!} = \frac{1}{1} + \frac{1}{1} + \frac{1}{1*2} + \frac{1}{1*2*3}+ ...$
