There has to be more to the question, anything?
Answer:
$4.86
Step-by-step explanation:
we must found cost of 1 slice of cheese first.
11 slices of cheese are $2.97
1 slice of cheese is $2.97÷11
18 slices of cheese are $2.97÷11×18 = $4.86
or you can calculated 1 slice of cheese
2.97÷11 = $0.27 and 0.27×18 = $4.86
both methods are correct
Answer:
Step-by-step explanation:
Area = 25 cm^2
1. Pretend it is a square
2. Multiply the two dimensions (5x10)
3. Take that answer and divide it by two (to get rid of the invisible square) (50/2)
4. Add the measurement
(-3, 2) -6+12=-6
(3, -2) 6-12=-6
Answer:
- zeros are {-2, 3, 7} as verified by graphing
- end behavior: f(x) tends toward infinity with the same sign as x
Step-by-step explanation:
A graphing calculator makes finding or verifying the zeros of a polynomial function as simple as typing the function into the input box.
<h3>Zeros</h3>
The attachment shows the function zeros to be x ∈ {-2, 3, 7}, as required.
<h3>End behavior</h3>
The leading coefficient of this odd-degree polynomial is positive, so the value of f(x) tends toward infinity of the same sign as x when the magnitude of x tends toward infinity.
- x → -∞; f(x) → -∞
- x → ∞; f(x) → ∞

<em>Additional comment</em>
The function is entered in the graphing calculator input box in "Horner form," which is also a convenient form for hand-evaluation of the function.
We know the x^2 coefficient is the opposite of the sum of the zeros:
-(7 +(-2) +3) = -8 . . . . x^2 coefficient
And we know the constant is the opposite of the product of the zeros:
-(7)(-2)(3) = 42 . . . . . constant
These checks lend further confidence that the zeros are those given.
(The constant is the opposite of the product of zeros only for odd-degree polynomials. For even-degree polynomials. the constant is the product of zeros.)
