Could someone help please?The Sales S (in thousands of units) of a cleaning solution after X hundred dollars is spent on advertising are given:
S = 10(1 - e^(kx))
Now when $325 is spent on advertising 2300 units are sold.

(a)Complete by solving for k. (Round your answer to 4 decimal places)
k = _

(b) What number of units that will be sold if advertising is raised up to $425
_ Units.

Answer 1

Answer: $2.3=10(1-e^(3.25k)))\n2.3=10-10e^(3.25k)\n10e^(3.25k)=7.7\ne^(3.25k)=0.77\n3.25k=\ln 0.77\nk=(\ln 0.77)/(3.25)\nk\approx-0.0804$

$S=10(1-e^{(\ln 0.77)/(3.25)\cdot4.25})\n$

Calculating this is a pain in the ***, but as a result you get approximately 2.8949 which in thousands of units is 2894 (rounded down since you can't have a fraction of a unit).

How is the graph of the cosine function different from the graph of the sine function? How is it the same?

Answers

Answer:

Similarity:

In Both cosine and sine graphs, a positive and negative number vertically flips the graph and tells whether the graph starts at maximum (positive) or minimum (negative).

Difference:

The difference between the sine and the cosine graph is the point where they start.

The graph of positive cosine starts at the maximum while that of the negative cosine starts at the minimum.

The graph of a positive sine starts at the middle, goes up and then down while that of the negative sine starts at the middle goes down and then up.

$(9x - 15)/(4) = x$ / * 4 (both sides)
9x - 15 = 4x / - 9x (both sides)
-15 = -5x / ÷ (-5) (both sides)
x = 3

(9x-15)/4=x /*4...... 9x-15=4x........ 5x=15........ x=3

g(x)=x+5/2. Find g(3), g(0), g(-3) and g(x)=0

Please solve this quickly. I need it right now. No silly answer will not be allowed.

Answers

Step-by-step explanation:

i. 3x-1=20

or, 3x= 21

x= 7

ii. 3x+1= 22

3x= 21

x= 7

iii. 2x-5=99

2x= 104

x=52

iv. g(3)= 3+5/2= 11/2

g(0)= 0+ 5/2=5/2

g(-3)= -3+5/2 = -1/2

x+5/2= 0

so, x= -5/2
