Answer: a) S'(1) = 136; S'(2) = 104; S'(4) = 76;
b) S''(1) = -38; S''(2) = -26; S''(4) = -2
Step-by-step explanation:
a) S' means first derivative;
(6t³ - 45t² +180t +130) = 6t² - 50t + 180
S'(1) = 6.1² - 50.1 + 180
S'(1) = 136
S'(2) = 6.2² - 50.2 + 180
S'(2) = 104
S'(4) = 6.4² - 50.4 + 180
S'(4) = 76
b) S'' is the second derivative of S:
(6t² - 50t + 180) = 12t - 50
S''(1) = 12.1 - 50
S''(1) = -38
S''(2) = 12.2 - 50
S"(2) = -26
S"(4) = 12.6 - 50
S"(4) = -2
c) Derivative is the rate of change of a function. The first derivative is the slope of the tangent line to the graph if the function in a determined point, while the second derivative measures how the rate of change is changing.
Analysing the values, we can conclude that the sales of the product after t months is decreasing at a rate of 12.
4 and 12 are the factors 48 is the product
Answer:
A
Step-by-step explanation:
Let x= number of visits she makes
9(number of visits she makes) + 32 (less than or equal to) <= 122
9x+32<= 122
Answer:
fire and in some places natural disasters but it costs.
Step-by-step explanation:
fire
There isn't universal coverage on the other two. If you can't pay your mortgage, generally the banks get very upset and foreclose. Banks are not very understanding about late mortgage payments.
natural disaster is usually not covered. Flooding earthquakes are usually not part of insurance coverage. Hurricanes aren't either. You can get such coverage, but it likely is not cheap.
Property taxes will cause the city to put a lien on your dwelling and there is usually no insurance for that.
Fire and with a lot of extra money natural disaster are your only choices.
