You've learned about the properties and characteristics of exponential and logarithmic functions, including their domain and range, what their graphs look like, and how they can be applied in economic and scientific contexts. Many observers assume linear rates of change in technology and social development. Inventor and entrepreneur Ray Kurzweil has put forth evidence of an exponential rate of change in human development of technology and draws some controversial conclusions about future change. Review this talk by Kurzweil, and discuss your reactions. Consider these questions:
• What leads many observers to assume a linear progression?
• Why do you accept or reject the evidence that Kurzweil presented of an exponential model of growth?
• What conclusions can you draw about change in the next 10 to 20 years based on an exponential model of growth in technology, communications, and other fields?
• What other areas of human or societal change have models that would fit an exponential curve?

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i
