Answer:
x(θ) = 5 tan θ
Step-by-step explanation:
Given that:
[tex]\int (25+x^2)^{-6} \ dx[/tex]
we are to state the trigonometric substitution to be used to find the indefinite integral.
Suppose u is the variable and a is the constant
u = x
a = 5
So; (a² + x²)ⁿ
which is a trigonometric substitution for x = a tanθ
Then,
x(θ) = 5 tan θ
In this exercise we have to use the knowledge of trigonometric substitution to calculate the indefinite integral, so we have that this is:
[tex]x(\theta) = 5 tan \theta[/tex]
Knowing that the indefinite integral corresponds to:
[tex]\int\limits {(25+x^2)^{-6}} \, dx[/tex]
we are to state the trigonometric substitution to be used to find the indefinite integral. Suppose u is the variable and a is the constant:
[tex]u = x\\a = 5\\(a^2 + x^2)^n[/tex]
Which is a trigonometric substitution for:
[tex]x = a tan\theta\\x(\theta) = 5 tan \theta[/tex]

Answer:
D
Step-by-step explanation:
Less than 75% of workers got their job through internet resume sites. A researcher thinks it has increased.
Express the null and alternative hypotheses in symbolic form for this claim. For example, if you have 35%, enter it as 0.35.
H0: p H1: p
Use the following codes to enter the following symbols: ? enter >= ? enter <= ? enter ! =
Answer:
H0 : p = 0.75 against H1: p > 0.75 One tailed test.
Step-by-step explanation:
We state our null and alternative hypotheses as
H0 : p = 0.75 against H1: p > 0.75 One tailed test.
In this case H0 is not defined as p≤ 0.75 because the acceptance and rejection regions cannot be set up. Therefore we take the exact value of H0 : p= 0.75.
The claim is that the probability of the workers getting their job through the internet is greater than 75% or 0.75.
As H0 is supposed to be less than we choose H1 to be greater than equality.
Write down each of the following statement
using the symbol a and the constant of pro-
portionality, k.
(a) p is directly proportional to q.
(b) y varies directly as the square of x.
(c) y varies directly as the cube of x.
(d) T varies directly as the square root of l.
(e) y is directly proportional to the cube
root of x.
Step-by-step explanation:
Option (e) is the right answer.

Solve for x x/5= 5 NEED TO KNOW FAST!!!! PLEASE
Answer:
x = 25
Step-by-step explanation:
Multiplying both sides by 5 (to get rid of the denominator) gives us:
x / 5 * 5 = 5 * 5
x = 25
