First you calculate the total cost of the pears:
18,4 pounds x $1,75 = $32,2
Them you add the cost of the pineapple:
$32,2 + $2,89 = $35,09
After this you can divide the total cost (35,09) for 4 friends getting the amount due to each one:
35,09/4 = $8,77
The graph shows that x=1 and x=6 will make the factors be zero. This polynomial has factors (x -1) and (x -6).
The 2nd selection is appropriate.
We are given
rectangle
length is 6 inches
so,
width is 4 inches
so,
now, we can find area
now, we can plug values
now, we are given scale
we can take square both sides
now, we can find 1 in^2
now, we can multiply both sides by 24
so,
Area of rectangle is 1536 feet^2..........Answer
Answer:
Total credit hours a student have = 2.5 hours.
Step-by-step explanation:
P.S - The exact question is -
Given - The tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h, where h represents the number of credit hours taken. The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h.
To find - How many credit hours will a student have to take for the two tuition costs to be equal.
Proof -
If the two tuition cost are equal, then
C(h) = S(h)
⇒250 + 200h = 300 + 180h
⇒200h - 180h = 300 - 250
⇒20h = 50
⇒2h = 5
⇒h =
⇒h = 2.5
∴ we get
Total credit hours a student have = 2.5 hours.
The first derivative of the function f(x) = x² - 5 is equal to f'(x) = 2 · x.
<h3>How to find the derivative of a quadratic equation by definition of derivative</h3>
In this question we have a quadratic function, in which we must make use of the definition of derivative to find the expression of its first derivative. Then, the procedure is shown below:
f(x) = x² - 5 Given
f' = [(x + h)² - 5 - x² + 5] / h Definition of derivative
(x² + 2 · x · h + h² - 5 - x² + 5) / h Perfect square trinomial
(2 · x · h + h²) / h Associative, commutative and modulative properties / Existence of additive inverse
2 · x + h Distributive, commutative and associative properties / Definition of division / Existence of multiplicative inverse
2 · x h = 0 / Result
The first derivative of the function f(x) = x² - 5 is equal to f'(x) = 2 · x.
