Answer:
<h2>33</h2>
Step-by-step explanation:
Given the average low temperature by month in Nashville is represented by the function f(x)=-1.4x² + 19x +1.7, where x is the month, the average rate of change is expressed as d[f(x)]/dx = 2(1.4x) + 19
d[f(x)]/dx = 2.8x + 19
Since the number of months between March and August is 5 months and x is in months, hence we will substitute x = 5 into the resulting function to get the average rate of change from March to August as shown;
d[f(x)]/dx at x = 5
= 2.8(5)+ 19
= 14 + 19
= 33
<em>Hence the average rate of change from March to August is 33</em>
Answer:
(See explanation)
Step-by-step explanation:
The function is:
Its simplified form is presented hereafter:
The resultant expression is a linear function, first-order polynomial, whose domain and range are the set of the real numbers.
Answer:
The correct option is B.
Step-by-step explanation:
The given equation are
On solving both the equation, we get
Put this value in the given equation.
The solution of the given system of equation is
The best approximation of the exact solution is (1.3,2.3). Therefore the correct option is B.
0.96 or 19/20
0.96 as fraction = 96/100 = 19.2 / 20 5 into 96 is 19.2 and 5 into 100 is 20
So 0.96 is the same as 19.2/20
Since 19.2 / 20 and 19 / 20 have the same denominator, therefore the 19.2 / 20 is bigger than 19 / 20.
So the 0.96 is bigger than the 19 / 20.
