Answer:
The area under the curve y = f(x) at x-axis, on the interval x E (5, ∞) is equal to 7.
Step-by-step explanation:
Solution
Given that:
f(x) = 7√x-5
The function of domain is:
D = x-5 > 0
x>5
so,
x← (5, ∞)
Now,
(1) The sequence root function is always known as positive, i.p defined from x E (5, ∞)
i.p =√x-5
Thus,
7/√x-5 >0
Therefore f(x) = 7/√√x-5 which is a positive integer, which is defined in domain x E (5, ∞).
Each value exist a real and unique values of f(x)
Now,
The function f(x) is continuous and over the interval(5, ∞)

Answer:
300 students
Step-by-step explanation:
To know the number of students, we must divide the total amount of milk spent by the amount spent for each and in this way we will obtain the value we are looking for, like this (both have the same units of L, so there is no problem ):
30 / (1/10) = 300
that is to say that there are a total of 300 students
Answer:
C
Step-by-step explanation:
The table shows a linear function.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (2, 7) ← 2 ordered pairs from the table
m = 
= 4, thus
y = 4x + c ← is the partial equation
To find c substitute any ordered pair into the partial equation
Using (1, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 4x - 1 → C
