The answer is 
Step-by-step explanation:
Now, to find the number of players to make the team by solving an inequality.
Let the number of players that can make team be 
Total number of players high school soccer team can have = 27.
Already players chosen by coach = 
.
According to question:
<em>Subtracting both sides by 18 we get:</em>
Therefore, the answer is
Hi there!
The perimeter of any square is the side of the square multiplied by four.
Perimeter= 4 x (5x-2)
Then distribute the four over parentheses.
Perimeter= 4(5x)-4(2)
Perimeter= 20x-8
Hope this helps :)
Answer:
The output for x = 2 is
Step-by-step explanation:
Function:
A function is like a machine that gives an output for a given input.
A function has an independent variable which is called the input of the function.
The output for a given input is called the dependent variable.
Here. 'x' independent variable
f(x) is the function dependent variable
So Put x = 2 in the f(x) we get
The output for x = 2 is
Answer:
59cm^2
Step-by-step explanation:
first you can do 8x9 to get 72 then you can subtract 4x2 from 72 to get 64 and lastly you have to subtract 4 from 9 to get the area of the small rectangle on the left so you get 5 and then you have to get the width which is 4+3 from the top and subtract that from 8 on the bottom which is 1 so now you have 5x1 which is 5 and subtract that from 64 to get 59cm^2
hope this helps
Information about concavity is contained in the second derivative of a function. Given f(x) = ax² + bx + c, we have
f'(x) = 2ax + b
and
f''(x) = 2a
Concavity changes at a function's inflection points, which can occur wherever the second derivative is zero or undefined. In this case, since a ≠ 0, the function's concavity is uniform over its entire domain.
(i) f is concave up when f'' > 0, which occurs when a > 0.
(ii) f is concave down when f'' < 0, and this is the case if a < 0.
In Mathematica, define f by entering
f[x_] := a*x^2 + b*x + c
Then solve for intervals over which the second derivative is positive or negative, respectively, using
Reduce[f''[x] > 0, x]
Reduce[f''[x] < 0, x]
