Answer:
1
Step-by-step explanation:
Here f(x) = x^2 - 2x - 5, which at x - -5 is 25 +10 - 5 = 30 and at x = 6 is 19.
The average value of a function f(x) over an interval [a, b] is
f(b) - f(a)
ave. val. = ---------------
b - a
which in this particular case is
19 - 30
ave. val. = ----------------- = -11/11 = 1
6 - (-5)
The average value of this function f(x) = x^2 - 2x - 5 on [-5, 6] is 1.
The axis of symmetry for this parabola is the x-axis. The general form of the equation is:
4p(x-h) = (y-k)^2
where the focus has the coordinates of (h+p,k)
Manipulating the given equation to the general form:
4(1/3)(x-7)^2 = (y - 0)^2
Therefore the coordinates of the focus is:
(7+(1/3),0)
The answer is A.) (71/3,0)
Answer:
600
Step-by-step explanation:
Given,
Numbers are 825 and 213.
If the number are equal or greater than 50 then one number will be rounded up. if the number is less then it will rounded down.
Like in this case 25 and 13 are less than 50 so, they will not rounded up.
825 will be rounded to 800.
213 will be rounded to 200.
Subtraction of number
= 800 - 200 = 600
Subtract $145-$53 and you will get 92.
Then divide 92 by 23 and you get 4.
The answer is 4 because when you subract 53 from 145 you are seeing how much you paid without the fee.
Answer:
28
Step-by-step explanation:
a³+b³= (a+b)³ - 3ab(a+b)
= 4³ -3×3×4 = 64-36 = 28
