Answer: f(x) = 3(0.7)^x
Because as the exponent (x) of 0.7 grows the result decreases. When x is a big negative number the decay is fast, when the x is a big positive number the decay is low, and the function appraches assymptotically to a constant value. This is the behavior of an exponentially decaying function.
Answer:
Up 1 and over 3
Step-by-step explanation:
The answer is 1000. 172,090 - 171,090 is 1000 so when you do it backwards and add 1000 to 171,090 you get 172,090. Hope this helps, good luck.
Answer:
6 laptops.
Step-by-step explanation:
$6500 is the budget. If each textbook costs $116, and 30 textbooks are needed, you multiply.
116 x 30 = 3480.
3480 was spent on the textbooks, and the rest needs to go into laptops.
6500 - 3480 = 3020.
Now to find out how many laptops can be bought with the remaining money, divide.
3020 / 439 = 6.88 (You can't buy a portion of a laptop, so you have to take the biggest whole number, which is 6).
