Well, this is a broad question but I would say pie. Pie is used very early on in secondary school and therefore a lot of people already know about it and how to use it. But for example if your a banker E would be more important as banks use e to calculate interest.
Hope this helps, have a great day.
Answer:
y = -2x + 28
Step-by-step explanation:
Slope intercept form is-
y = mx + b
y = y coordinate
m = slope, the rise/run
x = x coordinate
b = the y-intercept, the place the line crosses the y-axis.
Now, fill in the formula with the proper information.
y = -2x + b You can use the point (10, 8) for the x and y coordinates to find b
8 = -2(10) + b Now solve for b
8 = -20 + b
<u>+20 +20 </u>
28 = b Now substitute 28 in for b
y = -2x + 28
The possible functions for f and g are f(x) = 
and g(x) = 
<h3>What is an exponential function?</h3>
An exponential function is a mathematical function of the following form: f ( x ) = 
where x is a variable, and p is a constant called the base of the function. The most commonly encountered exponential function base is the transcendental number e.
Analysis:
If for every value of x being positive and y is a positive whole number and for every x being negative y is a positive fraction, then that exponential function has a whole number base, Other wise it would have a fractional base. From the above explanation, f has (1,3) (positive x and whole number y) and (-1, 1/3) (negative x and positive fraction y). so therefore f has a whole number base and g has a fraction base.
Therefore f(x) = and g(x) =

Answer:
√75, 9, 9.5, √99, 10
Step-by-step explanation:
that's what I got
Let tomatoes be as x and corn be as y.
Total cans is 36 cans.
$20.8 = 2080 cents
1. x + y = 36
2. 80x + 40y = 2080
From equation 1, we get
y = 36 - x
Substitute into equation 2,
80x + 40(36 - x) = 2080
80x + 1440 - 40x = 2080
40x = 2080 - 1440
x = 640 ÷ 40
x = 16
x + y = 36
16 + y = 36
y = 36 - 16
y = 20
Alex does buy 16 tomatoes.
