Answer:
65%
Step-by-step explanation:
325-195=130
130/200= 65
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.
Answer:
Step-by-step explanation:
well the negative correlations are the number of calories consumed and the amount of weight lost by a person and the thickness of the ice on a lake and the likelihood of falling through the ice.
Negative correlation is defined as an inverse relationship between two entities. If entity 1 increases, entity 2 decreases and if entity 2 increases, then entity 1 decreases.
So the postive are
the temperature outside and the number of pool guests
the number of children assigned to a class and the number of desks
the number of children assigned to a class and the number of desks
the price of apples and the number of giraffes in Africa
If we use the width as x we have 2x with both widths and 4x with both lengths. So 6x=24 and x=4. So length is 8 and width is 4.
You can first convert the mixed numbers into fractions and then operate them
if for example you have 3 4/3
to convert it you first multiply the whole by the denominator and then you add the nominator. The denominator is the same.
so 3 4/3=13/3
