What is the question tho?????
29 jars because if every box as 12 jars you multiply 12×29= 348
then multiply 29×16=$464
Answer:
f(x) = -5.1x² +14.6x +3
Step-by-step explanation:
The three given points are obviously not on a line, but can be modeled exactly by a 2nd degree polynomial. (The degree is 1 less than the number of points.) I find it convenient to let a graphing calculator's quadratic regression function tell me the coefficients.
<em>Solving by hand</em>
Since the "y-intercept" is 3, the equation can be written
... f(x) = ax² +bx + 3
Filling in the given numbers, we have 2 equations in the 2 unknowns, <em>a</em> and <em>b</em>.
... f(1) = 12.5 = a·1² +b·1 +3
... f(2) = 11.8 = a·2² +b·2 +3
Simplifying these gives ...
Subtracting the first equation from the second gives ...
... (2a +b) -(a +b) = (4.4) -(9.5)
... a = -5.1
The first equation tells us
... b = 9.5 -a = 9.5 +5.1
... b = 14.6
The equation is f(x) = -5.1x² +14.6x +3.
The best answer to go with is b
Answer:
<em>Answer: B San Francisco</em>
Step-by-step explanation:
It can be read that Geneva is 12°C colder than Nikki's hometown. It can be seen in the table that Geneva is at -3°C.
This means that Nikki's hometown is 12°C hotter than Geneva, thus:
Temperature of Nikki's hometown = -3°C + 12°C = 9°C.
The only city with a temperature of 9°C is San Francisco.
Answer: B San Francisco
